Yup. the 1542 series all supports standard floppies. That's what distinguishes then from the 1540 series. 1542B is a good solid card. I've got one in my unix machine. Place I was working at said they were too obselete to use. Other topic: I know it was mentioned here before that the rz23 drives don't autostart. Does anyone know if older macintosh's (say, an se30) can give the device start sequence? or if there's any simple way to force the drive to start anyway? -- Jim Strickland jim(a)DIESPAMMERSCUMcalico.litterbox.com ----------------------------------------------------------------------- Vote Meadocrat!

There were aftermarket 2880k external floppies with SCSI interfaces that would give an '030 cube (without its own floppy controller) or a Cube that'd been upgraded to '040 (and thus lacked the milled opening for a floppy disk on the front panel) a floppy disk drive. I have one of the more popular versions of this disk drive---a PLI SuperFloppy. Also, SCSI floppy disks were offered on some of the earlier HP 9000-700 series machines that also lacked floppy controllers. The 715/60, /80, and a few others had onboard floppy controllers that I believe support standard PC-type 1440k floppy disk drives. I can't test this because I need a keyboard interface (what a thoughtful design! q: ) for my 715/80 and have been thus far unable to locate one. These don't even come close to being within the scope of this list, though. The floppy disk drive that was an option on the old SGI Iris Indigo R3000 machines was also SCSI interfaced, and I believe had a 1440k capacity. -- ok r. r e d @ b e a r s . o r g =========================== [ urs longa | vita brevis ]

Besides the Kim-1 (which isn't mine <sigh>), I did acquire a few interesting things. I got a Radio Shack Micro Color Computer (the first in my collection!), a Sharp PC-5000 portable computer w/ built in printer and external floppy drive, and a Silent 700 Data terminal WITH manuals! I have several of the Silent 700's but this is the first manuals I have seen for the unit. There are still a number of bankers boxes full of documentation that I will be picking up in the future. Re: the Kim-1, there was also Educassette Computer Aid Digital Data Recorder with docs that is believed to have gone with the Kim-1. It looks like a neat system and the description reads "Uses the industry standard tape saturation method to beat all FSK systems ten to one. No modems or FSK decoders required. Loads 8K of memory in 17 seconds ..." There is a tape in it labeled 8080 software. I suspect the tape at least was not used in the Kim-1 :).
