Death of Ray Bradbury

by rampaginggreenhulk＠yahoo.com

>From the earliest writers, Verne, A.C. Doyle, etc. sf was all about futurism. They attempted to predict what the future would be like. Primarily. Some stories were set in the present. The combination became the genre as we know it today. Keep in mind a fair amount of scifi became scifact. ------------------------------ On Thu, Jun 7, 2012 11:19 AM PDT Curt @ Atari Museum wrote: >Bradbury was more of a Futurist imho.

which word procs used 2.5s David was Re: DD versus HD 5.25" floppy drives

by rampaginggreenhulk＠yahoo.com

name them please. We need a thorough discussion of w/p's anyway. The Canon VP-3000 is 8088 based in the event you werent aware.

The disk measured roughly 2.5" and stored analogue still images. This was fairly rare, but was much more common than the LT1 disk that the Zenith Minisport took. There was another 2.5"-ish disk called the QuickDisk which had a single track in a spiral.

Mystery Panel

by silent700＠gmail.com

I received this 23" panel strip recently along with a large lot of unrelated (DEC) items. I've tried some creative googling but have been unable to ID it. I'm hoping somewhere here may have encountered it in their past travels. Here is a gallery of pics: https://picasaweb.google.com/102190732096693814506/MysteryTelcoPanel Whatever it came from, it appears to be hand-wired with great care, perhaps even a one-off for its particular application. I thought at first it was telco-related, rather than computing, being a 23" rather than 19" mount. That may still be the case. Or, it could be both, given the intersection of the two industries. So, do those panel codes stir up any memories here? -- jht

P800 boards

by camiel＠camicom.com

I've completed a list of boards in the P800 haul: CPU BOX 1 - labeled P859 . CP7RA : 5111 199 62019 (P857R/A CPU for P858,P859) . MCU3 : 5111 199 77442 (Paper tape, serial control unit (partially populated)) . 2 x M128E : 5111 199 67592 (128Kx21 RAM) . MCU2 : 5111 199 78181 (Line printer, card reader control unit) .

AMA-8A : 5111 199 75318 (Asynchronous line multiplexer) . SLCU2 : 5111 199 69373 (Synchronous serial line control unit) CPU BOX 2 - labeled P859 . 2 x CP7RA : 5111 199 62019 (P857R/A CPU for P858,P859) . M128E : 5111 199 67592 (128Kx21 RAM) . MCU2 : 5111 199 78185 (Line printer, card reader control unit) . MCU2 : 5111 199 78186 (Line printer, card reader control unit) . MCU3 : 5111 199 77445 (Paper tape, serial control unit (partially populated)) . BIGD : 5111 199 73289 (Big disk (40/80MB CDC) controller) . BIGD2A : 5111 199 57852 (Big disk) The weirdness of Box 2 is - obviously - a second CPU in the same box. This can't be right. CPU BOX 3 - labeled P859 . CP7R : 5111 199 67589 (P857R CPU for P858,P859) . M128E : 5111 199 67593 (128Kx21 RAM) . TIMER CARD : 4022 422 20091 . ? : 4522 107 62304 .

CDD : 5111 199 78177 . CDD : 5111 199 78178 . 2 x MCU3 : 5111 199 78198 (Paper tape, serial control unit fully populated)) . MMU : 5111 199 75183 (Memory Management Unit) . GPC : 5111 199 79382 (Custom card) Box 4 just looks wrong. I don't know what the CDD cards are, but there doesn't appear to be a CPU or memory in there. However, there are P856 CPU's in the spare cards box, and I found references to the P856 being able to use MOS memory as well as core, so all might not be lost here.

SLCU2 : 5111 199 69373 (Synchronous serial line control unit) . TIMER CARD : 4022 422 20091 Looks like I should be able to get a few systems going with these parts. There's also a second box with spare cards, having different formats. Some of these are double eurocard format, like those used in the P85xE systems. There's also a spare power supply for a P859 box, as well as a spare power supply for a P856 box. I'm interested in finding out more about the cards I couldn't identify, these are: . ? : 4522 107 62304 . 4 x CDD : 5111 199 7817X . FLDB : 5111 199 69667 . 2 x MX : 5111 199 79335 . TIMER CARD : 4022 422 20091 I'm hoping CDD means Cartridge Disc Drive, and that these are the controllers for the X1215 disk drives. The 2 8" floppy disk drives are CDC BR8A8A type, looks like they are 800KB double sided, double density drives. They're very dusty.

Mac IIci/IIcx/Quadra 700 PSU schematics?

by fraveydank＠gmail.com

I've recently acquired a Quadra 700 from eBay. The power supply seems to be dead in the water; no voltage whatsoever on any of the lines, including the +5v trickle. Before I go delving into finding what may be wrong with the supply, does anyone happen to have a schematic for the GE version of this power supply? There's one available from bomarc.org, but they only deal with physical checks and mail, which means it would probably be about a week before I got anything back. Likewise, if anyone knows common failure modes for this particular supply (the Astec one has a known failure in the +5v trickle with a known hackish workaround, but the GE supply has a totally different reference designator schema and possibly completely different circuitry), I'd be interested in hearing about it. - Dave

2.9" spiral disks. Was: DD versus HD 5.25" floppy drives

Akai used a 2.8" spiral disk in a range of samplers in 1985. To add to the confusion, the disks were called QD, for "quick disk". The whole disk was read into memory in one read action, maybe that makes them quick. http://www.vintagesynth.com/akai/s612.php Fred Jan
