Have a mangled or broken ADB port on your keyboard or computer? While many times, the port may just need fresh solder, it is possible that something truly is broken.These are used and have been carefully removed and tested before and after to work.
This should work on every Apple external ADB keyboard, and appears to be identical to the one on the motherboard or logic board of the computer (Apple IIGS, Macintosh II/SE through Beige G3) as well.
Used to attach the keyboard or other ADB device such as a trackball.
This cable will work for Macintosh SE through early G3’s and the Apple IIGS.These 3′ coiled genuine Apple ADB cables may come with any of the following part numbers: 590-0361-A / 590-0361-B / 590-0616-A
These caps are unique to the Apple Adjustable Keyboard, Model M1242. The bottom row of keys are angled to fit the design. Key caps look Nice. The space bar assembly includes stabilizer wires and spring. Although provisions were made in every non square cap for wires, only the following keys have them and they are included: Delete, return, left and right shift, tab and caps lock.
Apple Adjustable Keyboard, Model M1242. This unique keyboard doesn’t share parts with any other model. Keyboard tested to work, although several keys have the common malady of not registering a key press and then you get a bunchhhhhh. Cosmetically Nice, it was missing the rests and flip down feet when it came in. Key caps are available on this page. Available here are the base plate, base plate screws (set of 6), side wing screws (set of 2, on set per side), flip down feet tension clips, and the top covers.
As soon as I figure out how to get the ribbon cable out of each side (see last 2 pics) more parts will be available. Please Contact me if you know how these ribbon cable clips work.
Apple Design Keyboard, Model M2980. This ADB keyboard was one of the last and most common models made before the USB keyboards were introduced with the iMac. Release in the early ’90’s, to match the Power Macs and Performa’s. It will work on any Mac with an ADB port from the Macintosh II to the Beige G3. This is the only ADB keyboard with an integrated cable.
Shown are some of the many variations in stock. Keyboards range from Nice, Light discoloration, Medium discoloration, and Severe and are priced accordingly. Most of the Severe only have discoloration on one end as if they were sitting on end inside an open top box in the sun.These will ship with a color matched Apple Desktop Bus Mouse II.
Apple Design Keyboard ~ Model M2980
There are 4 versions of the Apple Design Keyboard, M2980, that I know of. None of the parts are interchangeable.
Step 1, determine which version you need parts for by where it was made or assembled and what the flip down and rubber feet look like:
Pictured above in manufacturing date order, from left to right – USA/Mexico, Thailand, China. Last two photos are of the four different key caps all are an F15 key cap in the order of China, Mexico/USA, Thailand A, and Thailand B from left to right.
Thailand ~ Long, narrow flip down feet. (3) Rectangular rubber feet. Stamped label on left. 4 screws.
Alternate version has (2) rectangular rubber feet and 8 screws.
Macintosh II and SE to Beige G3, IIGS
This is the first ADB (Apple Desktop Bus) mouse made for the Mac. Family number G5431 was introduced with the Macintosh II and SE. It will work on all Macs through the beige G3 although it was replace by the Desktop Bus Mouse II in 1993. The Apple IIGS mouse is identical except for the model number.
There were 3 versions of the G5431 that I am aware of. The top and case look identical, the original is the one on the left with the black mouse ball (Taiwan). I think the one in the middle (USA) was next and the one on the right is the last (Malaysia).
Last photo shows some of the coloring variations, most will look like the middle two. They are matched to a keyboard if purchased together.
Apple M2706. Introduced in 1993, this one button teardrop mouse is the second and last ADB mouse model for the Macintosh. It works on any Mac with an ADB port from the Macintosh II through the Beige G3. It will also work on the Apple IIGS.
Cosmetics on this mouse vary greatly from very Nice, with no or little discoloration, Lightly discolored or faded, Medium or splotchy discoloration often seen in one area, and Severely discolorated to orange. Choose below, priced accordingly. All have been cleaned and work as they should. The mouse you receive may have a different color mouse ball and a stamped label instead of the actual label. When purchased with a keyboard, color will be matched as closely as possible.
Introduced in 1993, the Apple Desktop Bus Mouse II was the last ADB mouse model. On the outside they look the same, but I have identified 4 versions over their long life. No parts except the 7/8” mouse ball are interchangeable between them.
1) Made in Taiwan. These have black mouse balls. Manufactured by Logitech. Black ball cage. The mouse “tail” or cable is removable. The two screws holding it together are underneath the label. Ball retainer has no hole, and has 2 plain tabs on the underside.

A9M0331 & G5431 Parts
Introduced with the Apple IIGS in 1986, it didn’t have a name printed on the label, simply Model No A9M0331.
The Macintosh got the same mouse later – introduced with the Macintosh II and the SE. The label not only sported a name, Apple Desktop Bus Mouse, but was given a Family Number G5431.
Both numbers were used for the duration of this wedge shaped mouse, and there are several versions of them over the next 6 years.
If the mouse ball is black and there are two diagonal notches or cutouts on the bottom for the mouse retainer, all parts seem to be interchangeable between 1 and 2 below for the purpose of this website. The teflon strips are notorious for coming unglued on these versions, so priority is given to complete working mice, I cannot guarantee that the bottom case or retainer ring will have these strips:
1) A9M0331 (black ball). The mouse was made by Logitech in Taiwan. The controller board is beige colored on the top and green underneath. Printed on the underside of the board is “A D B Mouse by Logitech” and the particular one I am looking at says Rev C2. The interior ball cage is white. The mouse base is stamped 400116. The mouse top is stamped 400115. The button part of the top is stamped 400117. The retainer ring is stamped 400118.
2) G5431 (black ball). The mouse was made by Logitech in Taiwan. The controller board is green. Printed on the board is “Logitech AT Rev B”, P/N 200048-00. The interior ball cage is black. The mouse base is stamped 400116. The mouse top is stamped 400115. The button part of the top is stamped 400234. The retainer ring is stamped 400235.
3) G5431 (gray ball). This mouse was made by Alps in the U.S.A. The controller board is brown. Stamped Alps 820-0232. The gray mouse ball is 1” (25mm). The ball ball retainer is round with a V at the bottom indicating pull it down to remove it. There is no separate ball cage, it is part of the case. The mouse base is stamped 815-1090. The mouse top is stamped 815-1092. The button part of the top is stamped 815-1091. The retainer ring does not have a number. The lower teflon is not on the ring, but on the base. Upon removal of the board assy, one roller and spring may fall out. Two little white plastic supports for the other rollers may fall off.
The following two look identical from the outside, but the ball and ribbed retainer are the only parts interchangeable:
4) A9M0331 (gray ball). The mouse was made in the USA. The controller board is green. Unknown manufacturer, but board stamped 820-0146. The gray mouse ball is 1” (25mm). The mouse ball retainer (gray or black) is round and ribbed with 3 tabs that mate to the bottom of the case. The ball cage is white. The controller board is screwed to the bottom of the case with 3 screws.The mouse base is stamped 815-0733. The mouse top is stamped 815-0732. The button part of the top is stamped 815-0852. The retainer ring may be unstamped. Two or all three of the rollers are steel.
5) G5431 (gray ball). The mouse was made by Mitsumi in Malaysia. The controller board is brown. Stamped Mitsumi. The gray mouse ball is 1” (25mm). The mouse ball retainer (gray) is round and ribbed with 3 tabs that mate to the bottom of the case. The ball cage is black. The controller board is screwed to the bottom of the case with 2 screws.The mouse base is stamped 64-1259. The mouse top is stamped 64-1260. The button part of the top is stamped 64-1261. The retainer ring may be unstamped or marked 64-1262.

Regarding the controller boards: They are for parts or repair only. The mice used for parts do not work at all, have a smashed cable end, the cursor is very jumpy, or the click is funky – it doesn’t stay held down, or come up, or a single click is two, etc.
Introduced in 1987, the Apple Extended Keyboard, M0115 is Apple’s heaviest keyboard and first extended keyboard to include F keys and PC style navigation keys. Introduced alongside the smaller Apple Keyboard, M0116 it was offered as the other optional keyboard with the Macintosh II and Macintosh SE. Featuring an ADB port on both sides for cable connection to the Mac from one and a mouse in the other. As with it’s successor, the Extended Keyboard II, it includes guide posts for templates that came with many software applications. Still one of the most popular keyboards ever with it’s clicky Alps key switches!
Keyboard comes with an ADB cable and matching mouse. While all of the keys retain their original color (other than the spacebar), the cases are prone to discoloration. In stock are keyboards with Medium and Severe discoloration. The Medium has engraving on the top left corner.
Introduced in 1990, the Apple Extended Keyboard II, M3501 replaced the Extended Keyboard. Changes include some cosmetics, a slightly softer and quieter key click, and an adjustable height bar. Featuring an ADB port on both sides for cable connection to the Mac from one and a mouse in the other. As with it’s predecessor, the Extended Keyboard, it includes guide posts for templates that came with many software applications. Apple’s last mechanical keyboard, it is still one of the most popular keyboards ever with it’s clicky Alps key switches!
Keyboard comes with an ADB cable and matching mouse. Note that this keyboard came out before the Apple Desktop Bus Mouse II, so depending on your Macintosh Model, it would have been used with either mouse – Apple ADB Mouse or ADB Mouse II – take your pick.
Keyboards available as Nice, Light, Medium and Severe discoloration, and priced accordingly.
The template guide shown in the last picture is for illustration in case you’re wondering why the pattern of discoloration appears the same on many of these keyboards. It is the only one I have been able to locate and it has been modified by the previous owner, so is not included.
M0487 ~ Mitsumi
Keycaps for the Apple Keyboard II. These key caps are only used on Version A of Apple Model M0487.
Identifiers: The underside of the cap has a square post with round hole, and looking at the keyboard, there is a rubber cap sandwiched between the cap and the round, white switch. Serial number of keyboard starts with an M, and if you have taken the cover off, controller board and inside of top are clearly marked Mitsumi. Please refer to the Apple Keyboard II Parts page for more information.
Due to the number of variations (all keys are listed here), all other keyboard parts including the rubber cups and wires that go under the caps are found on the Apple Keyboard II Parts page.
The key caps from this set have medium discoloration. Wires and cups do not come with the caps and they are found here.
M0487 ~ SMK
Keycaps for the Apple Keyboard II. These key caps are only used on Version B of Apple Model M0487.
Identifiers: The underside of the cap has a rectangular post and legs that stick down, and looking at the keyboard, there is a white rectangular switch with wings. Serial number of keyboard starts with an S (also maybe T), and if you have taken the cover off, controller board and inside of top are clearly marked SMK. Please refer to the Apple Keyboard II Parts page for more information.
Due to the number of variations (all keys are listed here), all other keyboard parts including the switches, space bar spring and wires that go under the caps are found on the Apple Keyboard II Parts page.
These keys have light discoloration. The lettering on the keys – e – s – d – are worn. Key caps only – the wires and clips that go under large keys such as shift, space bar, etc. Are found here.
Note: Some of the plastic legs or posts on the underside of some of the keys have been bent or broken off. This does not seem to affect functionality. If this is a concern, contact me about the specific keys you are interested in.
A classic for your Classic or LC.
Introduced with the Classic and the LC, the Apple Keyboard II, M0487 was the second ADB keyboard for the Macintosh. It features an ADB port on each side – one for the cable to the computer and the other is to plug the mouse into. There are two flip down feet or legs in the back.
This keyboard will work with any Mac from the Macintosh II through the Beige G3 as well as the Apple IIGS.
The Apple Keyboard II includes a matching Apple Desktop Bus Mouse and an Apple ADB keyboard cable. Coloring ranges from Nice, with little to no discoloration to Light to Medium and are priced accordingly.
As you can see by the photos, the keyboard you receive may or may not have a rainbow Apple in the top left corner and may have no label, a paper label, or a stamped label on the bottom.
Discount available If purchased with a computer.
Repair parts for the Apple Keyboard II, Model M0487.
While they look identical on the outside, there are two versions of this keyboard available and none of the parts are interchangeable. According to Apple, Version A serial numbers start with “M”. Version B serial numbers start with “S” or “T”.
According to what I have in inventory, Version A (M) would have been made by Mitsumi, and Version B (S) would have been made by SMK. No keyboards with a serial number starting with T are in stock, so unable to verify manufacturer or parts at this time.
Other identifying indicators of which keyboard you need the part(s) for are:
If you have already carefully removed the cover of the keyboard, the inside of the cover and the controller (encoder) board will be stamped “Mitsumi” or “SMK”.
If you remove a keycap, look both at the underside of the key and at the keyboard. the underside of Version A (M), Mitsumi, has a square post with a round hole in it. The corresponding switch on the keyboard has a round rubber cup or dome over a round white post.
The underside of a key cap of Version B (S), SMK, has legs at opposing corners and a rectangular post. A white, plastic switch may or may not have come up with the keycap. If it did, you will see a spring sticking out the end of the switch. Looking at the switch on the board, will either be a large, white switch sticking up with a rectangular hole and wings on each end or a large hole where this switch goes (if it is still attached to the cap).
All other keyboard parts including switches, screws, case parts, controller, backplate, feet, springs and the wire and clips found under the keycaps are selectable below.
- Case screws are sold in a set
- Backplate / controller board screws are sold in a set
- The SMK (Version B) controller board has several mounting screws – they will go with the board
- The power button goes with the top case
- The backplate / membrane module assembly includes ALL switches for Version A (M) and only the caps lock switch (finicky) for Version B (S).
These were complete, working keyboards, the bottom case was broken in version A (M) and a combination of worn keys, a finicky caps lock and the loss of a few wire clips while cleaning made Version B (S) a parts candidate.

*Model number 62360 rolls smoothly, but needs a different (earlier) software version or dip switch setting as I can’t get the buttons to change from left = click, right = select and drag.
*Model number 64100 doesn’t roll as smoothly and may have issues rolling in one direction so may need the rollers adjusted. Buttons are perfectly programmable.

Mouse Systems A/3 Mouse. Model No. 403243-00. One of the first optical mice! This version was made for the Mac. As with many early computer items, very little information is available on the internet. I did find this interesting article at Low End Mac about optical ADB mice. This mouse requires the gridded mousepad from Mouse Systems to work. If I run across one, I’ll be sure to try it.
