Bill - I don't have an IMSAI PCS 80. But perhaps you would find something close in either a VDP-40 (never turned it on, 5.25" floppies) or a VDP-80. My VDP-80 got smashed in transit, but the ROMS could still be gone. Let me know if you want be to dig around Bob Roswell broswell at syssrc.com 410-771-5544 ext 4336 https://museum.syssrc.com -----Original Message----- From: cctech On Behalf Of Bill Degnan via cctech Sent: Monday, March 09, 2020 8:31 PM To: cctech <cctech at classiccmp.org> Subject: [EXTERNAL] IMSAI PCS 80 30 ROM (original) Hi - I am looking for an IMSAI PCS 80-30 ROM image made for with the Tarbell 1011 controller and Persci 277..anyone have this? I received a system and drive but I think the ROM was replaced and since then I was told the system would no longer boot. In the meantime I am going to find a drive and controller that is compatible. Or, ug, have to try to edit the ROM I have (version 1.1) to operate with this hardware. I would not having a copy of ROM 1.0 at least to start from scratch with. Thanks Bill Degnan
