STBook/STylus test board found

Postby sarnau » Tue May 09, 2017 8:49 am

I just found this board in the basement. Am I correct: it looks like a test board for an ST Book?

You have a really interesting basement. ;-) Would be nice to see a dump of the EPROMs on this board.

Fascinating! There's 128k of ROM and 64K of RAM on the board but also a three-wire serial EEPROM… There's also two GAL/PALs (one for I/O, one for Memory?) on there as well…

Any chance you could dump the content of the two EPROMs?
