Hi all, I've had another PET 4032 (2001N, no crtc) to repair lately. This one had an add-on daughterboard, a Microtech Spacemaker II, I believe it's a multiple ROM selector board that allows up to 4 ROM images to be switched on the same PET add-on ROM socket. It was removed by the owner of this PET so I'm unsure whether it was installed on $A000 or $9000 position, however it has two EPROMs onboard that I dumped and attached the dump here if someone wants to have a look and archive them should they be unknown so far. One is a 2716 labeled 8-4032-9", it reads always the same content with my DATA I/O 201, but always fails the verify mode. The other one is a 2532 labeled Basic Plus I (and 1980 COM4 OU 1581 on the back) and it reads and verifies fine. Can someone identify at least the starting SYS points? Thanks Frank IZ8DWF
