Hi Nicolas, I flashed some kernels for my SX-64 using the adapter in the VIC-20 but I haven't had time to test them yet. Unfortunately, when I swapped the VIC-20 EEPROM back in I managed to damage something so now the adapter doesn't work. Maybe we should take this off-list? I don't want to spam the list with this. Can I mail you on the x1541.de address I used earlier? /Niklas On Sun, Mar 7, 2021 at 9:16 AM Nicolas Welte <no_spam_at_x1541.de> wrote: > Hi Niklas, > > yes, I still have, or can make GALs for the 1541. > > Unfortunately, it turned out that the original design was in conflict with > all the I/O chip mirror addresses in the 1541, so I had to introduce a > patch wire to provide a manipulated A15 address line.
