Title: Help finding software and docs on a Development board with an EEPROM programmer
Post by: Straho on September 23, 2017, 04:14:31 pm
Hey guys, I have found this last week in the local flea market. It has an Atmel AT89C52 8 bit micro and several sockets for I presume flashing different EEPROMs. The only thing that identifies it is a small label on the PCB that says MULTIPROG Rev. A. Does anybody know where i can find info on this thing .. I can only find info on the Atmel micro ...everything else is ungoogable - no information whatsoever ..... I need documentation and software. Would be glad if someone has info on this :)

thats the beast :)

It clearly has a rs232 type serial connection - have you tried talking to ? It might identify itself.

It also has what looks like a second crystal in the middle of the cluster of programming sockets - I think this may be aimed at programming processors rather than EPROMs.

Thanks, I will follow the pinouts to determine a safe voltage and see if the thingie talks. Will post results when ready.

A quick Google suggests it could be PLC related.

There's a bazillion programmers like that out there. They're made by little outfits that come and go. I wouldn't be surprised if there was a lot of protocol re-use between models. The trick is to find models that obviously have an old 8051 MCU and an RS232 port. If they have USB, look for a USB-to-serial converter.

Maybe try:

In my searching, the "Wilar Programmer" kept coming up, and I've verified the Wilar Programmer SP200S uses an 8052 MCU. Probably start  there!

My beat is that this is an EPROM programmer
