Hello, all, As part of a project to revive a hacked-on 8K PET board, I was thinking about mass storage. I have one of Nicholas Welte's RAM/ROM boards here, so I can get around the defective ROM IEEE routines, but I don't happen to have a floppy drive with me (for those that might not know, I'm at the South Pole, and Winter starts in two weeks, so there's no time to ship one here, let alone the cost of moving a heavy beast like that). What I am after is something to plug into the PET's IEEE port that can emulate a drive up to "B-R" and "B-W" commands. For simple loading and saving, I have a C2N232, which will do for 90% of things, but there are a few programs (most notably Infocom's Z-Machine-based Text Adventures) that do direct block access. I have an ISA IEEE-488 card here, so one thought was to turn an old PC into a floppy drive emulator. It would mount disk image files and respond to a subset of CBM DOS commands (SEQ file load/save, "$", B-R, B-W...) I'm hoping I don't have to start from scratch, so I'm asking if anyone has seen any IEEE drive emulator projects out there and could point me to them. There are a few IEC-bus emulators (1541-III, etc.), but IEEE-488 drive emulators seem to be a bit less common. Thanks, -ethan Message was sent through the cbm-hackers mailing list
