[H]owever in the meantime I may just purchase a Unicomp Model M, seeing as they are the exact same thing, right down to the tools used to make them. As a former owner of a brand new Unicomp and current owner of a lot of Models M, at least one of which I'm probably going to post for sale today or to...

Nothing beats lead based solder in my opinion. :) Back when I had roommates they hated whenever I typed on my Model M LOL I never understood it. It's such a nice sound!!! I spent some time today cleaning my OmniKey and it's been used so much! The PBT keycaps are shined up! I'm having a few issues w...

Are you going to be using Lead solder? I would highly recommend it. My experience with Lead free solder in keyboards has been rather sad. It tends to crack and be more brittle then 60/40 tin/lead solder. Just to be clear I am not a professional and so your experience may vary LOL Cheers, --Given Do...

Does anyone on here possess the programming knowledge and tools to test, read and write EPROM chips? I ask because on my Mextel AutoKey 40 macro accessory board there is a EPROM chip with a quartz window on it. I think that this chip is what was used to store the boards operation programming and ove...

I might be able to provide you with a replacement taken from another Mextel Autokey 40, provided you can explain exactly how the Mextel works, as I have been unable to use it. I have been doing a lot of research lately on the components of the motherboard of the AutoKey, specifically the EPROM chip...

[…] If you would like, I could post some pictures of the flip tabs.

Please do!

There you go! I also did some research on the board and found out that the boards firmware was mostly likely stored on a EPROM chip, on the Autokey it is on the right side of the motherboard

The 74xx series chips are widespread and generic - many manufacturers make near-identical versions of those chips. Any other 74LS32 in that form factor will be a drop-in replacement. One to three extra letters at the front are a manufacturer ID code, an extra letter or two at the back is the packag...

I might be able to provide you with a replacement taken from another Mextel Autokey 40, provided you can explain exactly how the Mextel works, as I have been unable to use it. The one I purchased came with user instructions printed on the tops of the macro reference tabs that attach to the three pl...

I’m looking to replace a faulty logic IC on my Mextel Autokey 40. I googled 74LS32 and a whole bunch of options came up. I am unsure what do specifically look for when it comes to buying a replacement logic IC. I want to avoid buying the wrong one. Can anyone shed some light on my issue? I have atta...

I was thinking of doing just that, on un-related projects in the past, rustoleum has never let me down. I saw in your post that you used evapo-rust for your plate, I was thinking of doing that for mine, however in some spots the rust looks like it goes pretty deep sadly so I have decided to just san...

Thank you! The issue with the switch is that the switch plate itself is corroded beyond repair, not the contact leaf, but thank you anyways! I ended up buying 7 new old stock switches from eBay. I got 7 just in case another switch dies and I can’t repair it. I plan on taking all of the switches out ...

Here is the story of how I found this beauty. I was on youtube searching for reviews on a gaming keyboard I was looking to buy when I stumbled across a video by Chyrosran22 video for a $40 gaming keyboard (https://youtu.be/vsJq434UYTA). In the video he mentions that if you are worried about not havi...
