I have one model 21 and one model 11. Finch drive and ST506 drive respectively. Not sure about the status of disks, but I have a spare Finch drive. I also have three install tapes. One Sadie 3.5 and two ZEUS 3.21. When time permits I will read those. AJ Palmgren read a tape with a tar archive I ma

A very big and expensive door stopper without OS tapes. But most importantly: the CPU board is missing! The card in slot 2 appears to be an additional SIO card. This is a model 20, quite low-end. We have a model 32 (much rarer, I haven't found anyone else with a model 32), but it is non-functi
