you can't just write the guru rom. you need the oh-so-special adapter which you can't find anywhere ...

go for latest gvp rom (4.15) it should help things a little.

In the "old days" (when I was younger), I could have made one of those adapter boards. But my PCB chemicals are ancient, I wouldn't want to re-leard the process, and my eyes aren't as good and my hands aren't as steady, so I ordered the 4.15 ROM.

Thanks for the help!


Guru ROM adapter is not just a passive PCB. There's a GAL mounted, which probably does somekind of bank switching.
