< I visited a surplus dealer today and picked up an external hard drive <case that he was throwing out. The case has a Seagate 225 drive in it with <some kind of Western Digital interface card. The card has MFM connection o <one end and a 50 pin header on the other. The header is connected to a <cable that had a SCSI type plug on it. Does anyone know if the card is a <SCSI to MFM interface or what? Well St225 is MFM so the card is either a host to MFM bridge or SCSI(SASI) to MFM bridge. The real answer is a part number on the card like WD1002-HDO (host interface number). Someone else may be able to confrm if the SHD is SASI or at that time early SCSI. Allison

(SOT) IBM 730T and PCMCIA hard drives

by rutledge＠cx47646-a.phnx1.az.home.com

(somewhat off topic... only 5 or 6 years old and a PC at that :-) Well as I mentioned in that screenphone thread I bought an IBM 730T. There are lots of them on ebay right now at prices which make me wish I'd not bought that ill-fated DTR-1. This is a tablet type pen-based computer which has 8 megs RAM built-in, 3 PCMCIA slots and 1 RAM card slot which collectively take up the space of 2 type-III slots. So if you put in a hard drive you have 1 type-II slot and 1 RAM slot free. (I don't know if the RAM slot is what is known as type-I, but the pins are arranged differently and it takes a DRAM card... I'm hoping those cards are interchangeable regardless of manufacturer but I'm not sure. IBM intended a 4 or 8 meg card to go in there.) When you turn it on, there is no BIOS setup screen that I have found, it just immediately proceeds to load DOS off the 105 meg hard drive that came with it. Mine came with nothing other than command.com loaded on it so I have no way of putting other software on right now. Floppies for them are rare and expensive. I tried borrowing a coworker's laptop last night to transfer software to the hard drive, but I couldn't make it show up in any of WinNT, FreeDOS or Linux. So I will have to either buy a floppy or a PCMCIA card drive for a desktop PC I guess. I want to try and put Linux on it and get X working with the pen. So if any of you have any of the following for sale or trade: PCMCIA hard drive with more of DOS installed so I can use intersvr at least or Linux a clever substitute for that PCMCIA slot for a PC floppy for the 730T other ideas on how I can try to install Linux ... let me know. I have quite a significant pile of junk^H^H^H^Htrading stock. Hmmm, matter of fact I think I'm going to go add a list of stuff to my home page right now because it's accumulating fast and I need to start losing some. I don't know even if I get Linux onto it, if the fact that DOS boots without any card services being installed, implies that Linux will also see the hard drive as an ordinary one or if I'm going to have to build a kernel that has the PCMCIA support compiled in rather than as modules. I'm beginning to wonder if the hard drive itself is special. Since there is no BIOS setup could I get it to boot from a different sized drive... and maybe also this accounts for why the hard drive didn't look normal to the other OS's. -- _______ http://www.bigfoot.com/~ecloud (_ | |_) ecloud(a)bigfoot.com finger rutledge(a)cx47646-a.phnx1.az.home.com __) | | \__________________________________________________________________

Hamfests, Amiga Drives (was: Re: dumpster diving and other sources , of goodies

If anyone is looking for a similar item, I have a box of Sony MP-F11W-72 drives, 720K DSDD 3.5" floppies for various Tandy boxes, including the Tandy 1000. One catch: they don't have a power connector. They draw power over the 34-pin data cable. Typically, floppies have grounds on the odd pins; this one scopes out thusly... 1 NC (uninstalled jumper at RJ1 (GND) and R1 (?)) 3 NC (uninstalled jumper at RJ3 (GND)) (FAQ claims +5VDC) 5-11 +5VDC 13-19 GND 29,31 NC (uninstalled jumper at RJ7 (GND)) (FAQ claims +12VDC) 33 NC (FAQ claims +12VDC) (cf. the Tandy 1000 FAQ - http://www.oldskool.org/~tvdog/1kfaq.html#II.C ) There is a space for a power connector, but it is not installed. If you feel like migrating a connector from a dead floppy, it's doable, but for non-Tandy use, a modified cable might be the better solution. I got these from the Dayton Hamfest in a "you want one, you take the box" deal from the local Radio Shack guys that used to have a great booth in the white tent in the corner of the flea market. I will never use more than one or two of them. Now's your chance to stock up on bizarre Tandy drives. -ethan ===== Infinet has been sold. The domain is going away in February.

Available in San Antonio, TX, moderately boring stuff.

by mtapley＠swri.edu

All, At the Texas Thrift Store in San Antonio, loop 410 just south of Ingram, I found: AT&T 6300 and Xerox box - these two looked identical except different color schemes. Both $6.95, "as-is" and the Xerox says "works". Xerox claimed to be made in Italy, I didn't check AT&T. Apple IIGS - mmmm...$13.95? I didn't write it down. "as-is" Franklin Ace 100? - ... $6.95?? "as-is". All boxes were seperated from monitors, keyboards, cables, manuals, software - bare boxes only. I did not spot any such peripherals which looked at all related to any of the above, but didn't look very hard. If anyone is interested, email me offline and I'll buy, pack, ship, and let you know how much it cost to do all three. Hopefully, you'll then send me a check for that amount... - Mark PS are announcements like this of value to anyone? Should I continue them? Move them to the auction-announce list? Comments offline preferred, online OK if they are of general interest.

AT&T Sequent. . .

The classic place to begin such a search is in a long-standing minicomputer rag called _Processor_. They're mostly PC-clone ads these days, but they still have a few pages dedicated to DEC and Data General equipment, and there are certainly many outfits in there that'll be interested in quality (i.e. not PC-clone) terminals, network equipment, printers, etc. See http://www.processor.com/ for their on-line presence. It's expanding, though it's still not nearly as good as the actual printed edition. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

AT&T Sequent. . .

It might cover the Wyse terminals but it is more PC based. It has some mini stuff but I doubt the Sequent, routers, bridges UPS etc. Pawn shops use it to evaluate what they will loan on equipment. They are published by Orion Research Corp. in Durango Colorado. It is published yearly and cost about $150. It is actually blue colored. I could help evaluate it if they want to contact me off list. I suspect they would be shocked at the actual valuation. Of course it depends on the age of the equipment. It might be a candidate for a rescue though. Is anyone on the list running a Sequent.

IC question and hamfest finds

by dogas＠leading.net

-----Original Message----- From: Joe <rigdonj(a)intellistar.net> > ... Mike Haas came down from jacksonville and we went to the first day of >the Orlando hamfest. Mike scored big time! No less than 6 different TRS >computers. Several are like new and in their original boxs with all the >books. He also bought several other interesting toys! > It was fun! A boxed coco2 and mc-10, and letsee... a model 4, a model 1 L1, a model 1 L2, a Holmes Expansion Interface, 2 disks, a light pen, and ;) the plug&power controller with docs and cassette software. Non Radioshack stuff included a prettily outfitted Atari Portfolio, a Covox voice master again for the atari I hope, an Epson hx-20, and ;))) an Applied Microsystems diagnostic cpu emulator with a 6809 pod and documentation. I drove back down there later Sunday and didn't see anything more than I had on Friday, and am in some respects glad. This haul will take awile to assimilate.... Cheers! - Mike: dogas(a)leading.net

IC question and hamfest finds

by allisonp＠world.std.com

< What the Cosmac board? Let's see, It's 8 1/4" high x 9" deep. It has a <edge connector with about 88 contacts with what looks like .156" spacing. <There are four 1/2 AA size batteries near the top. Probably Nicads. They'r <growing white fuzz. The CPU is near the edge connector and is a RCA CDP <1802CE. It has the number 936 below the CDP number. Below it are three ZIF <sockets, two of them have 2516 EPROMs in them. To the left of the CPU are <two AMI 8039 22 pin ICs. All the other ICs are SSI. On the bottom edge it <says "TRANSYT CORP. CPU T-3020". The end opposite the edge connector has a < Any idea what it's out of? It is an 1802 CPU. the 936 is the 36th week of '79 most likely. Nope, not any of the 1802 SBC I know of and the connector was not typical of hobbiest class machines. My guess is a custom app. Allison
