<How about an original Shugart Technology (now Seagate) ST506 drive, <first year they came out? Forget the year now, must have been 1980 or I have a sample from 1980, still working. along the way it was ued to test a disk controller using NEC d7261 in an early XT. BEfore that it was on a multibus 8088 system and it was my first drive when I got a teltek controller. It's still good and I checked reciently it still has the copy of CP/M I last updated in 84ish before bumping up to a Quantum D540. I still have a sa400 that was original to the NS* MDS-A controller (1977) and a later SA400L both working. <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. My NS* is running a soft sector controller I built in '81(765 based) though the MDS-A is still operational in a netronics box from '79. Both are still in use and used for assorted development work. 20 and 19 years later! Allison

Interesting VAXen drive problem

by healyzh＠ix.netcom.com

This is just sort of a FYI message, I've already solved my problem. It started off easy enough, I needed to use one of my Q-Bus VAXen, and was planning on using the big old MV2. Turns out one of it's power supplies is apparently dead :^( Haven't really had time to look into that. No problem says I, I'll just throw one of the disks in my VAXstation II/RC. The disk freaked out and made some really alarming noises. Turns out the RQDX3 is apparently bad. I replaced it, and then it told me the drive was off line. I proceeded to give the system a good checkup, and couldn't find anything wrong, finally I pulled the other HD out of the MV2. It worked just fine. The answer to the problem appears to be that the first HD had been initialized on a Emulex controller which is the primary controller in my MV2, the second one was initialized on a RQDX3 (the secondary controller in the MV2). Both had bootable VMS installs on them, unfortunatly the one I needed was the first, but I've now got that taken care of. Just an interesting and educational problem I thought I'd share.

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
