Minimum hardware requirements (Was: Old, but not "Classic"

Actually, now that I think about it, I think it was Xenix it ran. But I know I saw SCO mentioned in it somewhere. >The Altos 486 was so called because it supported 4 users on an '86. Ok, that explains the name, anyway. Thanks for that. Cheers Geoff Computer Room Internet Cafe Port Pirie South Australia. netcafe(a)pirie.mtx.net.au

What is a Motorola Exorset ?

by rigdonj＠intellistar.net

I picked up some more odd-ball manuals. One of the ones that I got is for the Motorola EXORset 30 XDOS Operating System. From the description in the introduction, the system appears to be a development system with two SS 5 1/4" floppy drives and 16K of RAM. Is anyone familar with this system? Anyone need the manuals? Hmmm. Just found a couple of more manuals for this. These manuals are for a GPIB card and an Input Output card. Lots of schematics and hardware descriptions in these manuals. The pictures show large cards similar to S-100 cards but with 86 contacts. The descriptions mention 8" discs containing 6809 code. Joe

The system was intended to be used as 68xx development system for Motorola products, but I've also seen an 8080 Assembler :) Gruss hans -- Ich denke, also bin ich, also gut HRK

I saw a strange machine here a couple weeks ago. It was called an Altos 486, and a guy brought it into the shop because it had a password and he couldn't get past it. He thought it was a 486 PC obviously, but when he brought it in, he brought a serial terminal in with it! When we eventually fired it up, it turned out to be running SCO Unix (somewhat trimmed!) on an 8086, with (I think) 512k of RAM. It also had z80's on there, port controllers I think. Evidently it multitasked pretty well, it had 4 terminal ports and was bundled with a business package, that did debtors & creditors, stock control and word processing etc. I'm trying to get him to part with it. The guy is about smart enough to turn on a light switch without written instructions, but I tried teaching him enough about it to make it useable for his (very) simple purposes (just some record keeping) but it was a hopeless cause. I'm going to do up an old 386 with a VGA monitor and see if he'll swap it for the Altos. Seems he bought it at auction (thought it was a pc because it said 486) for A$40. Anybody here got any more info on it? Couldn't find a date on the machine itself, but the chips seem to be circa 1979. The terminal was also an Altos and was ansi/vt100 based. It also had a Wyse 50 term with it. Cheers Geoff Computer Room Internet Cafe Port Pirie South Australia. netcafe(a)pirie.mtx.net.au

modern removable media drives

by CLASSICCMP＠trailing-edge.com

>There was a ST3144A that liberally screamed in loud howling noise >when it went through it's death throes. At a lab I once worked at, a Fuji 2284 (14") drive in the computer room developed bad bearings and started screeching. We call System Industries field service, they log into the disk control unit remotely via a modem, check the error logs, and tell us there's nothing wrong :-) Tim.

On-topic Headcrash story..

by jpl15＠netcom.com

In '86 (in another life) I was a Systems Analyst for the deregulated side of GTE... I was also the MIS department, the LAN cable stringer-crimper, and I got to explain RS-232 to ex-PBX salespeople who trying to make a buck in the Brave New World... Anyway, my expensive 3Com server began to 'whistle' at about 10kHtz one day, and by the next morning it was screeching and warbling and quite obviously dying quickly. While it *was* backed up (the entire sales and marketing division was running in those 300 MBytes) I still had throughput goals to achieve, so I got the 3Com tech-rep out. By the time he arrived people were coming in my office to see what that awful noise was... I couldn't believe it was still *spinning*... let alone reading and writing. "Yup." He said. "No problem.." It was the absolute filter in the top cover of the drive. They offered to fix it... not under warranty!!! because it was not mis-performing... just annoying the hell out of all and sundry. Two whiny childish tantrums later... I got a new drive, which poor me had to format and restore to... all one Saturday... it was apparently a common problem w/that particular line of (Seagate??) drives. Cheers John
