A friend of mine has the same burner, and happened upon your channel when he saw me post a video of your about the teletype restoration. He needs to burn EPROMs for some older analog tape machines that we still use to record music. Your video helped him a lot.
Data IO made some real tanks. I used a later one attached to a VT100 to program EPROMs for use in a satellite I worked on in the early 90's. They featured a multi-voltage driver for every pin, so they were theoretically a universal programmer.
I suppose that design schematics for this unit are not readily available. I don't know where one would begin to find them. Do you think that this will end up being a "trace every circuit path" project. I hope you can get it working. Keep up the great videos!
That sent me looking... It appears to be a Cherry M8 or Hirose Cherry switch: mousefan.telcontar.net/jiku.htm mousefan.telcontar.net/image/hc20.htm deskthority.net/wiki/Cherry_M8 deskthority.net/w/images/d/d1/Keymodule_M8.pdf Now that they are repaired, they have the greatest key feel, solid and very easy to actuate. No slop.
That's what a sensible person would do! It looks like it supports devices all the way back to 2732's, albeit as one generic device (the Data IO has many different settings per brand). But I wouldn't get to play with a clunky 1980 device, and I don't think it would do older 1k or 4k bipolar PROM (program once!), which is really what I am after. But most of all, it would be way less fun!

It'd be horribly ironic that if to fix one of these you needed to reprogram it's EPROM. ;)
Love those old power supplies. None of that switching rubbish!

CuriousMarc the playlist for this is set up backwards! :o
Oops. Thanks for reporting. Can you try it now?
great, do you have a type/specification of the old and the new fan?
Not so old as sof of our products still use EPROMS for operational and programming software.... :)
Did you follow up the use of Caig DeOxit with Caig MCL after the switches dried?
Maybe a Tantalum capacitor went bang?
I think those are Alps keyswitches.

+CuriousMarc What did you use to clean the keys?
It's just Deox-it.
i think that you are awesome!
Thanks and great organ playing Emil!
+CuriousMarc haha! Thanks!
You load hex file or bin?
MCUmall programmers won't work?

what year was this product manufactured?
I believe 1980 for the 29A. This is a B, so a few years after?
+CuriousMarc thanks
