Hi all, I've just programmed an 82S100 (actually a clone, but my DATA I/O 2900 didn't complain and verifies ok) with the .jed file contained here: http://www.zimmers.net/anonftp/pub/cbm/firmware/computers/c64/82S100%2bJedec.zip The programmed IC gives a black screen on my SX-64 (It works fine with the original F93459 chip). The F93459 IC seems unreadable with the 2900 anyway, it gives just an almost all "1" jed file, so maybe they can be protected or the 93459 isn't really readable as an 82S100 (the 93459 is unsupported by the 2900 it seems). Can anyone confirm that jedec file is good? Checksum verifies correctly too. WTF? Frank IZ8DWFReceived on 2020-05-30 01:46:27
