Hi Mips (are you named after the microprocessor architecture?) Yes! I have a 1987 Model M myself. In my opinion the keyfeel of Ellipse's Model Fs is much better. Sound-wise, I'm not sure. Model Fs sure are loud and harsh. Good to know, thanks. As for the beamsprings, Input Club is doing something a...

Resolution is noted in the review: 216 ppr / 49 cpi. Low by modern standards, but numbers are not exclusive property here: with freely spinning ball, different usage technique is used. You can flick the ball in desired direction, and stop it when the pointer has reached intended zone. In fact, quite...

Speaking of inflation here's someone selling a rubber dome Lexmark Model M that's got a broken cable and missing six keycaps asking for $49 USD. If it sells for that I've lost faith in humanity. https://www.ebay.com/itm/Lexmark-IBM-Model-M-Rubber-Dome-Keyboard-Made-In-USA-P-N-1398601-Read/1847654904...

I talked about this in another thread, but wanted to put it here for reference. The instructions/links in TMK/QMK GitHub are a bit dated and contained some worries about clones not working. The instructions on GH for making a Pro Micro version require a 3.3v system, so here’s how to do it with curre...

How do you actually make one? I've read about it a couple of times over the years and always stumble on the "Arduino USB shield" hardware part. The one I could find was bulky and discontinued. You’ll enjoy this. Here’s my BOM: Bootleg Leonardo $13.88 Bootleg USB Host Shield $11.99 Project Box 2-pac...

Okay. I believe I know what is going on here. It is indeed 9600 baud and there are indeed two codes for each key press / release. But it is reverse polarity from what the microcontroller expects, that is, idle low rather than idle high. C3-Maestro-ESC.png Normal key down is C1 and normal key up is C...

There are easy ways to dump 8048/49/50(?) ROMs. I may look into throwing together a little PCB for this as I think it would be very useful to have in the future. You're right; I was confused about which models still had that capability. I do have such a reader here already. I don't think the chip i...

An 8049 has a masked ROM, so there isn't a (practical) way to get the program off of it. It's possible that there is a newer Service Manual around someplace that just hasn't been scanned yet. So I actually mapped the matrix and sold the keyboard a while back, so I can't test it anymore unfortunatel...

This Micro Switch SD-16192 / 78SD12-6 board has an AMI encoder. SD-16192-top.jpg SD-16192-bottom.jpg SD-16192-converter.jpg Most switches are 4B3B, 2.5 oz. sink pulse. The key in the lower-left is 4B8B, 8.0 oz., but still a pulse, which is close to synchronized with the strobe pulse. The three keys ...

better be careful around this snake

Yes, be careful!

Here shot_1608622786.jpg The keyboard is just a USB HID, remove it and build your own enclosure with cherrymx or whatever and a screen if you want. Added bonus GPIO. That being said I agree with Findecanor that most of MCU we use today inside keyboards are more than capable of doing anything and mo...

That is almost the perfect board for replacing the controller in given it is mostly single sided and also has diodes so you will not have the keypress limit and also should have a fairly logical order. What i find helpful is to draw the layout of the board itself and the connections to the old cont...

This is an external keypad for a Toshiba T1000/T1200 8086 laptop. toshiba-case.jpg It is model PA7354E and from around 1987. toshiba-back.jpg It has Mitsumi switches, so it's okay for the time, but nothing special. What is unusual is how it connected to the motherboard. It has a 2.5mm mono sub-mini ...

Oooh. Google has results. Here's a take-apart guide for an Apple Extended Keyboard II, M0312 and M3501. I couldn't immediately find a guide for the M0116, but I saw a post that said that all it has are the four screws on the bottom case and that's it. No snaps or anything. If this is your first time...

Thanks for the reviews and photos BucklingSprings and Scarpia! BucklingSprings, regarding the Unicomp key binding, it was discussed previously in the thread I believe to move the stabilizer insert about 1mm higher, and/or add a felt pad or O ring on top of the stabilizer insert to help reduce the bi...

You could also take a look at Matias boards, but then you won't have genuine Alps switches. But the Matias clicky is really, really nice. Backing up slightly, if you do get a Dell, make sure it really is model AT101W. If it's something like "AT101RW," it's a rubber dome. It doesn't help that they o...

A follow up to my earlier "project philosophy" message (from a discussion over on GH): In the below file, check out page 49, IBM 4704 section, 4662 and 4677 keyboards (F62 and F77): $21 a month minimum maintenance charges per keyboard as of January 1984. The F62 cost $340 and the F77 cost $375 in 19...

Hi, here's a quick update - your comment on an "auto-configuration-feature" made me searching the net ...

I got his board with NMB Hi-Tek switches some time ago. nmb-110695-top.jpg nmb-110695-bottom.jpg All the chips have 84 datestamps, so I assume it was made around 1985. There is no OEM branding that I can spot. It shows no sign of ever having been used and came in its original(?) foam-lined box. It a...

Great work! It works perfectly with my HP 98203C keyboard, it seems to use its device specific 'Keycode Set 2' like below. Interestingly, the keyboard has no ghost-blocking and phantom key can appear with specific three keys. I had broken its rotary encoder a few years ago and can't test the dial un...

Awesome piece of history you got there! It definitely seems like a prototype for IBM's 49-key POS keyboard (and its LCD-equipped Model M8 cousin), which has two slightly different variants; a silver-square badged one possibly known as the IBM 3320 (for 4683/4684) made in Mexico (possibly in their ow...

Made in 1986 silver badge M122 for 49.99$ is decent price.

oops...shipping is inflated to make up for the decent price...
