I have a pair of P112 systems, both with GIDE interfaces, booting CP/M from CF cards successfully. I have not done anything with RSX180 though. I have been meaning to try and get one reading/writing 8", ideally 3270 format, CP/M floppies, but have not gotten around to working on this yet, and have no idea how easy or difficult that might be. When I put these together and was getting them working initially, Terry Gulczynski was very helpful. See his site at http://www.stack180.com/ You may want to get the latest P112 ROM image and corresponding CF card image from his site. Mark -- Mark G. Thomas <m...@misty.com>, KC3DRE
