Hi! I'm looking for info on the SUN-3 floating point accelerators like the FPA, and FPA+. Programming info, header files, maybe even the libraries if they're avaliable. Also, before I pop in to motorols.com, does anyone have a quick little snippet of code to excersize a 68882? I just upgraded my SUN-3/280 to a '882, and I want to verify that everything's working right before I solder in some sockets and start playing with the clock. Thanks! Bob

Drive inventory

by vcf＠vintage.org

Ok, I scored quite a few drives for my data conversion machine project yesterday: Iomega Ditto Easy3200 (floppy interface) Colorado T4000 (SCSI) Exabyte EXB-8200 (SCSI) Bernoulli Box 20+20 (DC-37 proprietary?) WORM Drive of some type (SCSI) QIC-150 tape drive (SCSI) Iomega 150 MultiDisk (SCSI) Iomega 90 Pro (SCSI) DAT of some type (SCSI) Iomega Jaz (SCSI) Iomega ZIP (IDE) Conner 420 (floppy interface) Colorado 250 (floppy interface) Archive 4320NT DAT (SCSI) Conner 700 (floppy interface) Colorado T1000 (floppy) SyQuest EZ135 (SCSI) The trick now is to figure out what is downward compatible with what and eliminate those drives. The Conner 700 is obviously compatible with the 420, the Colorado T4000 is probably downward compatible with the T1000, the Iomega 150 is downward compatible with the 90, I think the Ditto drive is basically the same as the Colorado Jumbo drives and the Conners, so I would want to choose the one that is most downward compatible in terms of maximum storage. I have no idea what various DAT formats there are so I'll have to research that. Ditto for the WORM drives (I have one more somewhere in my collection). Did the Bernoulli Box have a proprietary interface? If so, does anyone have one they want to get rid of? I would imagine I can hook as many of the floppy interface drives as I need to a single cable, providing I can crimp on the proper connectors. Will there be any issues with conflicts or power? I imagine as long as I'm not using two drives on the same cable at a time then I should be fine. I think I have QIC-40/80 covered. My Tecmar QT-125e does QIC-2 up to 125MB, but from what I can tell from research that standard goes up to at least 500MB. I'm still trying to figure out what QIC-1000 is. Tecmar is still around (www.tecmar.com) but they only do Travan and DAT. Their older products (QIC and 8MM) are obsolete and they don't have drivers available. I guess what I really want to know is if the various tape drives from different manufacturers for a certain specification, say QIC-40/80, read and write the same low- or high-level format. So for instance, if I create a tape on a Colorado drive and stick it into a Conner drive, will the Conner be able to read it? -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

That, and they _never_ significantly lower the price of their media. A Zip disk still costs $15.00 in quantity 1 in this era of 19 cent CDRs; Jaz 1GB are still $100.00 per, and may heaven help you if you need a Bernoulli 90MB cartridge! In 1991, they were about $90.00-- today, they're about $90.00. >It's just another IOMEGA boondoggle, though.

nice find - now I have a PDP-11/93 question

by GOOI＠oce.nl

The 11/93 is hardly "classic", but to my DIGITAL collection it is still a nice addition and I would like to get it running. I agree with Jerome that the M9047 grant continuity card could be removed and move all other boards one position 'up', but the system had the M8047 when I got it, so I left it there. Perhaps the cooling of the cpu board is better ... > What do the DL interface connections consist of? I have a set > from an 11/94 system, but they really don't seem to fit from a > hardware point of view into a Qbus system, in particular, in a > BA23 box. That is exactly what I have. It is an 11/93 in a BA23 box. I read somewhere that the 11/94 uses a KTJ11 (?) board to bridge to UNIBUS, and that the 11/94 system comsumes more power. The rear panel that connects to the M8981 in my BA23 box has the following parts on it: + 8 9-pin D-shape (DE-9) connectors for 8 extra terminals + 1 25-pin D-shape (DB25) connector with "CONSOLE" text next to it + 2 7-segment displays + 1 DIP switch block with 8 switches The M8981 board has on the front side a 40-pin male header, next to it are the 8 LEDs followed by a 50-pin male header. Behind the LEDs is an other DIP switch module. The 40- and 50-pin headers are connected to the rear panel with 2 flatcables. I am still looking for the DIP switch positions. I will gather all info on the 11/93 and put it on my website. Of course with several pictures of the system. Several Google searches did not produce much technical detail info. TIA, - Henk.

festivals, flea markets, and surplus dealers

by jon＠slurpee.org

I'm rather new to the mailing list, and I poked through some of the previous messages on the site, but didnt see this one directly answered. I live in texas, and know of a few here haaug meet, first saturday, san antonio's 2nd sat, but is there a place where I can find out more of them located in this area (texas, oklahoma, arkansas, lousiana)? I figure here would be the best place to ask, because I'm really not interested in buying pc stuff, but love old unix equipment, and misc electronics. Any huge festivals that I should be going too every year that I'm not? (I go to trenton nj)... what about surplus places (I love to find junk at places that take computers to scrap them for metal... I get some awesome deals there)? Any help would be nice :) Thanks, jon

card punch

by lemay＠cs.umn.edu

Well, my latest acquisition finally arrived from England (why are all the good things in Europe...). Anyways, I finally have a Hollerith Manual Card Punch. You can see a picture of one at the Computer Museum of America web site: http://www.computer-museum.org/collections/hollerith.html Mine was made in england, by International Computers and Tabulators Limited. Does anyone know if that company was a part of what became IBM, or did they just make an unauthorized copy of the machine? My punch is slightly different that the one at that web site, in that it never had a nameplate below the keys, and the uppermost button on the picture isnt a part of my card punch. Basically, you have the 12 keys that punch the 12 hole positions and advance the card one row, with a button to inhibit the advance so you can multi-punch the same row (or allows skipping a row), and a second button that releases the remainer of the card. The button that is missing in the design of the punch I have must not have been very useful, as I cant imagine what else a person would need to do. There is an adjustable card stop, so that you can set the punch to allow you to skip any number of initial columns on each card automatically. The chad just drops to the ground underneath the punch. If I can find some information about this punch, i'll make a nice web page about it. -Lawrence LeMay

FA: Intel MDS-800

by rigdonj＠cfl.rr.com

<http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=2002926621>. He has no docs, drives or software with it. Damm! and I just threw out a drive chassis that went with this one! FWIW it uses CDC drives like these <http://www.classiccmp.org/hp/mds-800/cdc-dr-f.jpg>. I don't know if Shugart drives can be made to work with his controller cards or not But Intel uses a different connecting cable and a different set of controller cards for the Shugart drives. One the MDS-800s, the Shugart drives uses M2MFM encoding that's not capable with any other system that I know of but the CDC drives use MFM encoding and the "standard" CPM disk format aka IBM 3470 format.

I thought DAT was the audio format (48Khz, 16[?}bit, up to 4 channels), and the tapes are pretty identical to DDS? I do have a DDS (DDS2, I think) drive that will read/write audio DAT in my Indigo2.

Old manuals

by dtwright＠uiuc.edu

A couple weeks ago, I was given the following manuals and thought I'd see if anyone wanted them, otherwise they're getting dumped. - 3 Teletype corporation binders labeled "Technical Manual" -- there's more on the labels, but I don't want to type it all out. If you're intested I'll write it all down and post it. These are from ~1974. - IBM Customer Engineering Manual of Instruction for "24 card punch" and "26 printing card punch" (appears to be from ~1962) - IBM Personal Computer Professional Graphics Display Technical Reference (includes specs, logic diagrams, etc) (1984) I don't own, nor do I plan to own, any of this equipment, so I thought I'd pass these on to anyone interested... you'd need to pay shipping but that's it.

Nitpick alert: DDS = DDS-1 (ie, it's the same thing -- originally called DDS but now sometimes called DDS-1 so that it's clearly not one of the later versions). So there are only 4 formats, not 5. Nitpick 2: 8mm is not DDS or DAT. It's Exabyte videotape. -- Pete Peter Turnbull Network Manager University of York

It has been my experience over several years that the only problems with incompatible hardware compression on DDS drives was with the original generation of DDS and DDS-DC drives, before DDS2.
