I am now a proud owner of an OSI Superboard II
First a little about me, I am an Electronics Engineer who loves electronics as a hobby too. During the day I volunteer at a tourist railway doing things from electronics design (doing a new automatic gearbox controller) to auto electrical and it.
I live in Perth Western Australia, just outside the Swan Valley
My My Superboard nearly works. It can get to the W/C/D/M ? Screen, caps lock is on if I scope the data bus I can see changes when I hold a key down and release it. After a random time 0 -30 seconds I loose most of the address bus. It looks like it is hitting a small loop. I will connect a logic analyser and do a trace from power up. I re seated all the socketed chips, sprayed all sockets with deoxit, swapped cpu. I have read all the roms but can not find a list of checksums to see if mine are still good.
Any ideas great fully appreciated
Regards,
Kat.
