Hi, gang. A couple of years ago, I dove headlong into the old computer collecting thing, thinking naively that I was doing something unique. I was going to build a great online museum, and have all these neat machines displayed thoughout my house and possibly at the local university. Then I discovered this list, and realized that not only was I not alone in my pursuits, but that I was also small potatoes compared to some of you. Plus, the collection started to take over the basement, as they are wont to do. I also design theatrical sound effects, and I'm trying to build a small project studio here in the basement. That endeavour has taken over most of my free time. So, I started paring down the collection to a few choice pieces plus those with sentimental value to me. I did a entire display at the local library of Tandy equipment last year. I realized, while setting it up and subsequently taking it down, that I should keep the Model 1, the 100 & 200, the Pocket, and the Micro CoCo and jettison the rest of the Tandy collection. Rather than put this sucker on ebay, I thought I'd give first shot to my extended cyberfamily here on the list. I'm going to start with a Model 12, with two 8" floppy drives, keyboard, and two external 20mb hard drives. Don't know how well it works, but I was told that it booted last time it was powered up. I don't have any software other than what's loaded on the hd's. I've realized that I just don't have the time and no longer have the inclination to mess with all of this stuff, so it should go to someone who does. As I said, this is going in the kitty to finance the purchase of a synth or two for the studio, so I would like to get something out of it. This one wasn't a freebie for me. Also, if you know what one is, you know how bulky and heavy they are, so I would like to limit it to pickup in the Northwest Indiana/Chicago area. Valparaiso is about halfway between Chicago and South Bend, Indiana. Actually, I don't care where you live. If you're willing to drive to Valpo, that's fine with me. If you have problems with this email address, as my provider filters based on ORBS and sometimes things get stuck, use my work address pbraun(a)olivellp.com. I'll take the best offer as of Tuesday May 1st at midnight. Depending on how this goes, I have more Tandy pieces that I'll put up here first instead of ebay. I also have a mess of Bytes from the early 80's on that I'll offer as soon as I get 'em sorted, hopefully this weekend. Thanks.

MicroVAX 3100 booting... (now WinNT shutdown)

se/30 disk weirdness

by red＠bears.org

I brought home an external FDHD for my SE/30 last night, to facilitate retrocomputing tasks. Plugged it in, switched on the Mac, tested it out, shut the Mac down, and unplugged the disk. Now, when the external drive is unplugged, the system somehow still thinks it's there. I get a disk icon with an "x" in it at boot as it tries to boot from this external drive which is not there and finds (surprise!) no system folder on the disk. The system then goes on to boot more-or-less normally from the internal SCSI disk. Once finder starts loading, I get a dialog box that (depending) says one of two things: "This disk cannot be read by this Macintosh. (Eject) (Initialize)" with the icon indicating the (non-present) external floppy. ~or~ "Initialization faild: disk is locked. (OK)" Dismissing these dialogs result in processing resuming normally for a second or two, and then another identical dialog being thrown up. Repeat ad infinitum, et ad nauseam. The internal disk drive continues to work normally (within the above constraints). As soon as I reconnect the external disk drive, everything is happy again. As soon as I disconnect it... bang. Nose demons. I am utterly baffled. What's wrong? How do I fix it? ok r.

Motorola 68000-16 and 68450 chips...

Motorola made a version of their MC68HC000 that ran at 16MHz. Back in the late 80's I was doing processor design for Nortel switching equipment and we had some applications that were written for the 68000 that would have taken too much work to convert software over for the 68020 (a lot of our stuff ran in supervisor mode, not user mode). SGS-Thompson was a licensee for the 68K family, and was the first company that produced a 16 MHz 68000. I think theirs was NMOS, not CMOS (it sure got warm). One day the Motorola guys brought in one of their sales managers to try do drum up business for their 68020 and I showed them the SGS-T part and asked them if they had anything like that. The answer was "we'll get back to you on that", which was then followed up with "you can use our 12 MHz 68HC000, run it at 16 MHz at room temperature for development, and soon we can provide screened parts that will run at 16 MHz". Eventually they did provide MC68HC000-16 parts. Regards, Alex The Calculator Museum Web Page http://www.calcmuseum.com

MicroVAX 3100 booting question...

by kees.stravers＠iae.nl

On 2001-04-26 classiccmp(a)classiccmp.org said >I respect Apollo most for their solution. >On the early models we had they had a soft shutdown >switch right where the power switch was. You hit that >one and it does the preliminaries and then off. >>>>One button<<<, just the way it should be I think. The AT&T 3B2 does this too. Very nice indeed. I wish more machines had this feature. My old DEC 486 laptop did it even better: you hit the switch, it goes off instantly, and when you hit the switch again it came right back up where it was, no rebooting, no scratching on the disk, just instant on.

IBM 7171 Terminal Controllers

by ip500＠home.com

If anyone is interested ... there are a number of IBM 7171 that will be coming available in the near future. I would expect the price to be in the $100 range but as they are IBM .. they're probably HUGE and BLUE. Any interest I can find out more info and pass it along privately.
