Fixing "old" (but not quite classic) IDE and MFM drives?

by jeff.kaneko＠ifrsys.com

While we're on this subject. . . Does anyone out there have a copy of SpeedStor that can access Storage Dimensions old 8-bit scsi host adaptors? (Specifically, the DataCannon 800). I'm trying to test an old scsi MFM controller board, and I need to format the drive, first! Jeff > > > On Tue, 16 Jun 1998, Charles E.

Fixing "old" (but not quite classic) IDE and MFM drives?

by bjorn＠ktb.net

Hi, I've got a question about "borderline" classics. I've got a few old PCs >from right around 1990, maybe a bit earlier and I've got several small IDE and MFM drives that I've scavenged from various places. Several of these drives seem to almost work (they make the usual sounds at power up and can be detected by the bios of a newer PC) but they won't format/fdisk for me. Anyone have any tips of things to try as far as simple troubleshooting? Or are they doomed for the dumpster? Thanks, Bjorn

ATT 6310

by ddameron＠earthlink.net

Hello all, I have found a AT&T 6310 PC box. Can anyone tell me anything about it? Is it 10 years old, yet? It is heavy enough I'd thought it had a large linear supply in it, but only a switcher ps! It was made in Italy by Olivetti, as mentioned on the 6300 thread. Opening the top reveals a AT type passive motherboard- the CPU, etc. is apparently on another one in another compartment below it, which I haven't gotten to yet. All the cards are 8 bits, except a Mouse Systems serial card which extends about 1/3 way into the "16 bit extension". There is another 2 port serial card and also a MIcrosoft Inport card with a mini-DIN connector. There is also a serial and printer port on the "hidden" CPU card, both DB-25, and a DB-9 connector for the keyboard. There is a volume control on the front, but haven't found the speaker, either. -Dave

RA82: Does it need...?

by emu＠ecubics.com

Hi Bruce, ---------- > From: Bruce Lane <kyrrin(a)jps.net> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: RA82: Does it need...? > Date: Tuesday, June 16, 1998 12:21 AM > > Does the DEC RA82 drive need to see an active SDI controller in order to > spin up without a FAULT light? I know that RL02's needed power on the > controller before their FAULT indicators would clear. as far i know, YES. My ra90 spins up without sdi controller, but after few seconds you get an error with soemthing like "sync errors" whitch means there is no communication. then you never get the ready light. hope it helps, emanuel

The way I understand it, IDE drives should automatically map out bad blocks, (is this true for all IDE drives?) whereas MFM disks won't. Therefore I'd assume that once an IDE drive starts presenting bad blocks to the user its days are pretty numbered... I was once told that a small percentage of an IDE disk is unused, purely for the sake of providing a "reserve" area so that the disk could cope with some bad blocks whilst still giving the user the impression that full capacity was available - is this true, or just one of those stories that I happened to turn up over the years?? cheers J. >

Old Microsoft stuff...

by photze＠batelco.com.bh

Hi. Now, I don't want to start a flamewar, but still, Microsoft HAS played an important part in personal computing, for better or for worse. From 1986 or so onwards, they were a industry dominator. Now, from what I understand, the origional MS logo was GREEN? Somebody have a picture? Other than OS's and current Office Applications (and, of course, Internet Explorer, which is a decent browser, and DOES have pleanty of innovation, if you're prepared to admit it.), what did MS make? Anything for say... the Apple II? PDP's? UN*X boxes (once again, omitting current ports of IE 4.0)? Thanks, Tim D. Hotze

Backwater areas Was: Re: Cross listing Ebay items

<> Say a real goodie shows up, like a perfect DEC Straight-8 or an unbuil <> Altair kit. Assume the price is good, Assuming the price was affordable I'd drive a good distance. So far I've gone as far as 180miles. For a working PDP-8(any) I'd cross a few states if I could swing it. For an altair... I have one, thanks. I've assembled three of them back when. Have the shirt, been there. I'd look for an IMSAI it was a better machine. Allison PS: periodic request... IMSAI IMP-48 docs, I'm looking for a copy.

Windows CE: Future classic (OT, in a way...)

by peacock＠simconv.com

I know I can type it as: "You know, the 00's really suck!" But how the heck are we supposed to pronounce it? Simple, as anyone who owns a .30-06 deer rifle can tell tell you, it will be the "double ought" decade. Same as 100 years ago, the first year will be "ought zero". BTW, .30-06 is a US rifle caliber, .308 inches (7.62mm), designed in 1906, or "thirty ought six". 20 years from now, we'll be talking about that old 500Mhz P II made back in "Ought One".
