Can't find a lot of info on this rom, and it's not in my minipro chip supported list.

Any suggestions as to what I can use to read this chip? It's the ROM of a fairly rare system it seems, I'd like to archive it for posterity.

It is a Samsung 128KX8, CMOS, DIP32 and the datasheet is out there but does not give much info as to what it compatible with or comparable to 🙁
Do you have a PCI NIC with a 32pin rom socket ? If so you could try NSSI or other software ROM reading utility.....

The datasheet quite clearly says "JEDEC standard", which means this chip is compatible with nearly any other 128K x 8 DIP32 EPROM, EEPROM or Flash ROM, like e.g. the Winbond 29ee011 Flash ROM or the ST 27C1001 EPROM. I guess that winbond chip is supported by the minipro. If you can convince the minipro to read the chip like a 29ee011 even if it does not respond to an ID command, you have the dump.

Thanks, I was able to dump it as a 27C010 chip once I figured out how to disable chip id checking.

Hi there, what kind of this rare system?

Cheers,

Oh sorry, it's an Emerson 4412EC. A 286-12mhz with some nice built-in features.

Could you post a copy of the image file here, for anyone else who may need it?

I posted it in the Vogons Driver library thread.

Cool, thanks
