2 IBM 5.25" external floppy drives available + mics old PC stuff

by gunther＠aurora.regenstrief.org

Hi cleaning out offices and found 2 IBM 5.25" floppy drives EXTERNAL says something like "type 4865" on the bottom and has some 50-ish pin male plug. Also an old AUI/BNC ethernet card and a 128 kB memory extension card. This is in Indianapolis. Let me know or by the end of the week this stuff is going to dumpster. -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

GEM-OS

> -----Original Message----- > From: Bryan Pope [mailto:bpope@wordstock.com] > Does the GEM TOS have any relationship to the GEM OS > that was available > for the PC? (Other then name) Indeed it does. GEM was DR's GUI that sort of "went with" CP/M, though, not many people that I know of really used them together. It was available for a few systems, though, I can't name them other than MS-DOS and Atari's STs right off. Atari is the major exception (in that TOS is actually based on CP/M...

BA23 vs. BA123 vs. 42" cabinet?

by doc＠mdrconsult.com

Hi, all. I went last night and picked up (OK, dragged, while groaning) the MicroVAX Terry Murphy posted for rescue Thursday night. I'm fairly certain he hadn't ever used it, as the description was not terribly accurate. There was no DELQA, several of the cab kits aren't there, memory is only 16M, etc. Nice haul, anyway. The thing came in a 42" elephant-ear cabinet, which is in fair cosmetic shape, and without plugging it in, I'd guess good to excellent functional shape. Some QBus boards I can't ID, and the other goodies that came with, I'll post separately. So. I'm not enamored of the idea of running a 240VAC rack in my garage if not necessary. That leaves me with two other ideas. 1) The "drawers" are simply BA23 enclosures, right? Any reason I can't use the primary enclosure as a stand-alone unit? It's going to be running a minimal set of hardware: KA655 CPU Dataram 63016 16M RAM DMV11 (simply to occupy the last CD slot) DEQNA/DELQA (whichever I can scrounge cheapest, first) TQK50 (undecided) RQDX3 (with probably only the RX50 or an RX33 attached) That _is_ the right bus order, isn't it? Will either the power requirements or cooling be a problem? What if I decide to run the RD54 instead of the TK50? Is it OK to run the BA23 without skins, lying flat? And, if I want to run the second backplane and extra drives, can I just stack them? 2) I can put all the above in the BA123 lurking downstairs. But it seems a huge waste of space & power over the BA23. Plus, I don't have cooling vanes for the dual cards in the added CD slots, or enough D<mumble>11 boards to go around. Plus, the BA23 I can wedge into my office, but the BA123 would have to live in the garage. Advice, discussion, points I've missed, all welcome. Doc

Inter-Listmember Contact Difficulties

by dquebbeman＠acm.org

There are a number of denial-of-service attacks under way on ther Internet all the time, but we're in a wave of heavy attacks right now. Once by one, DNS servers are getting hijacked, and as a result, domains are evaporating into the ether. Sometimes, one person can get through to another for a while because their domain remains cached somewhere along the route. But eventually, you get cut off. When it happend to us last week, our ISP tracked down the hijacking machine, which itself had been hijacked, and managed to well, it has a cold, shall we say? Nice to have an ISP with good Kung Fu... ;) In the meantime, list members might volunteer to get word through to some member that some other particular member might not be able to reach. And there are these things called telephones, too... -dq -Douglas Hurst Quebbeman (DougQ at ixnayamspayIgLou.com) [Call me "Doug"] Surgically excise the pig-latin from my e-mail address in order to reply "The large print giveth, and the small print taketh away." -Tom Waits

need the use of a scanner with sheet feeder (near Seattle if possible)

Too thin. Intuitively, I thought I'd get better results (fewer rips) by feeding the opposite edge into the gripper. But more taint tore that way than when fed in hole-edge first. And in the old days, I did repair pages using the hole reinforcers (back before they were self-adhesive and thinner than they are now), and the result is that the manual takes up twise as much space in the binder. No, I want to meet the genius who invented this binding system. Like GBC but not GBC. I also would like to find a connection for the yellow construction-paper (not really but that's close) that CDC used for the 70s era covers. Some mill in Minneapolis must have a ton of it laying around... -dq -Douglas Hurst Quebbeman (DougQ at ixnayamspayIgLou.com) [Call me "Doug"] Surgically excise the pig-latin from my e-mail address in order to reply "The large print giveth, and the small print taketh away." -Tom Waits

Ancient Ampex core memory board

by borisg＠unixg.ubc.ca

Hi: During a search I did tonight trying to locate info on a core-memory module, I kept running into references to this list, so I thought I'd joing. I've been going through some of my ancient electronics stuff and just came across a 42*100 bit Ampex core memory module. This module has P/N 3255780-01 S/N FA 2655 04570061. It consists of 2 boards fastened together with screws and spacers with the core plane sitting on the lower board under a plexiglass cover. It appears to be made up of 2 separate core planes of 42*50 bits. The board is 5.5 * 5.5 inches by 9/16" deep. The edge connectors are broken off, for their gold plating I suspect. I have a faint memory of picking up this board around 1976 in a computer surplus store. I've separated it into two boards (connections between the two boards are made by 12 wires soldered to the boards) and scanned it and these jpegs are available if anyone needs them to help out. I was wondering if anyone had any information of where I can find more information about this core-memory module. I haven't been able to find out anything about the IC's which populate this board (TI AAAL4 and Fairchild AAVA1) and even info on what these IC's are would be usefull as the board appears to be a simple 2 layer circuit board with very wide (compared to modern boards) traces that are trivial to convert to a schematic by using the scans of the two sides of each board. It would be neat to get this board up and running someday, and hopefully someone on this list has the info. Regards, Boris Gimbarzevsky
