This was mail-order from a wholesaler, in 1993. $287 got me a Maxtor 213MB SCSI drive. Which is a little over $1/MB. << How about an original Shugart Technology (now Seagate) ST506 drive, first year they came out? Forget the year now, must have been 1980 or close to it. It ran me $1500 with a case and power supply, no controller, all for a gigantic 5MB and a blinding fast 90msec access time. That would be, oh, about US$300/MB. That much gets you an 18GB disk these days. I used a Konan controller connected to my IMSAI, development for Z80 code and BIOS device drivers for CP/M v3 and MP/M. I still have that drive, though it doesn't read/write so well now, but the head still moves ok. The IMSAI has had many a MFM drive since those days, the Konan (not very good) was replaced by an SDS VersaFloppy III, and it's due for an upgrade to a 3.5" Tandon 20MB in the near future. I plan to mount it on a prototype card inside the chassis and eliminate a cabinet. Maybe even 3.5" floppy if I can find some 720K drives. For all you purists who want to keep machines original, what do you do when the machine in question isn't retired yet, and there are 20 years worth of upgrades installed? I figure that old IMSAI will be running for another 5-10 years yet, cranking out the occasional Z80 program. Jack Peacock
