I was thinking like "ok, there are two extra ROM sockets, so they should be ROM A and B, no idea what the ROM9 is".

Olaf: spot on, both about the memory location and that I was using 8032: the Visicalc ROM was supposed to be at ROM9, and now it's working! I can now run my original VisiCalc disk's image with the dump of the original protection-ROM inside xpet, great! Thanks.
