I guess that you have to learn French first. :-)
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

So the next problem is the far right gang does not appear to be working :roll:

IMG_1105.JPG

I swapped the EPROMS around and it had no effect.

So I swapped the panel (bank of 4) with the other side and the form as well. So that fault is definitely on the panel!

After continuity checking the EPROM to the bottom pins, it was clear there was several things not contacting. Oddly the ZIF sockets actually seem to be in sockets! :shrug:

IMG_1107.JPG

Unsoldered the thing. Afterwards I realised I probably needn't have bothered doing this! :roll:

IMG_1108.JPG

Removed the two tiny screws.

IMG_1109.JPG

Gave it a good dose with contact cleaner spray.

IMG_1110.JPG

Then back together again. Now continuity checks all fine!

IMG_1111.JPG

Quick cleanup.

IMG_1112.JPG

Sockets soldered back in.

IMG_1113.JPG

Hurray!

IMG_1114.JPG

Next up to get a serial link to my PC!

That does look a nice bit of kit, not that I ever have to burn more than one rom at a time but I bet you enjoyed the challenge of getting it running again.
If it ain't broke, test it to Destruction.

Next problem is I get "framing error". No idea why.

The manual says:
RS232-Framing
While receiving data through the RS232 port, a framing error has occurred because
a valid stop bit has not been detected. Check that the baud rate, number of data and
stop bits, and parity are the same for both the programmer and the remote
computer.
I have matched the programmer to what it is set in windows but makes no odds :roll: .

@exxos are you using a USB serial or a proper one on the computer MB? Some old stuff I used to use would not work with USB adaptors.
