Probably not counting... DECserver 200/MC

Is it not yet ten years old (for this list)? If not it's close. I was responsible for one or two in 1988 or so, and we got it from somewhere else so it must have been around for a little while before then. It's a terminal server. I never took a screwdriver to one but it clearly had some smarts inside. To the best of my knowledge it will not do TCP/IP, but my knowledge is a bit dated. Maybe DEC found a way to cram it in there but I think they only had TCP/IP support in later models of terminal server. On powerup it has about enough code in it to download the code that makes it useful over Ethernet using DEC MOP. Supposing it finds a willing MOP server with the appropriate loadable image it will then be able to do DEC LAT over Ethernet. So you could hook terminals or modems up with it and have them talk to a LAT host, or you could hook up a printer and establish a LAT print queue on a VMS host, or you could hook its serial ports up to some other computer's serial ports and set it up as a LAT server that other LAT users could connect to. Is it useful/usable with -11s? I don't know, I used it with VAXen, but that's been eight or nine years ago and I don't really remember them that well. -Frank McConnell

GridPad 1910

by sinasohn＠ricochet.net

I recently got a GridPad model 1910, and I have a few questions... Does anyone know of a source for batteries? (Mine doesn't have one) Is there a version of basic specifically for the gridpad, or does anyone know how to get input from the screen with a general PC Basic? Does it require any special type of keyboard? Anyone have any documentation for it, especially for the docking station? connector on the bottom? Anyone have or know of software for it? This thing is pretty rugged, and I'm thinking it would be great to mount in my Land Rover to use for navigation (which means finding a DOS-based nav program that can work with a GPS.) Thanks! --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad sinasohn(a)ricochet.net that none but madmen know."

I got (not yet -- it's on its way) my Amstrad PDA-600 for $60. Dauphins are more than a Pilot. Of the lot, the HP's are probably the most powerful.

Sick PDP-8/f: Need Diode Info!

by mcquiggi＠sfu.ca

Hi David: > boards for decoupling capacitors, if their is one near each chip then that > is what it is, any .01uf ceramic would replace it. It would be on the > traces to the corner power and ground pins. Well there ARE a bunch of them, they ARE near several ICs, and they are in parallel with one side at ground. I think you're right. I think I have found the major problem with my board: The symptom I'm experiencing is that the DC OK H line, nominally 3.2V, drops to 2.2V when the M8310 is inserted into the backplane, and then the machine doesn't work anymore (not really, just can't RUN from the toggle switches). This voltage stays constant at 3.2V either on an empty backplane, or with all boards except the M8310 installed. Put the 8310 in and the voltage drops to 2.2V. I've traced this DC OK H pin to the input of a 7404 IC on the 8310 board. With power off, the gate's input and output are seen to be at ground, i.e. I think the gate is shorted. I wonder if you could look at your printset and see where the DC OK H line actually goes and what happens after the 7404? I think this is a bad chip.

Victor 9000

by jrkeys＠concentric.net

This machine came with a green-phosphor, slow-phosphor screen that's sharp and rock steady. The screen tilts up and down and left and right for maximum comfort. It has a silent keyboard with a large shift key next to the Z, the return key is also large, and the cursor-movement keys are separate from the numeric keypad. The disk drives are 5 1/4-inch and hold 640k each and are expandable to 1200k each. 128k of user programmable memory is standard. It sold for $4995 new. It had a 16-bit processor like the IBM and you could buy a plug-in card that increased the memory by 64k for $600 that also had the Z-80 microprocessor on it and allows you to run CP/M. This was called a Victor-80 Card. The 9000 does excellent monochrome graphics but it will not do color graphics. Hopes this info helps John Keep Computing !!!

<Well I want it for my CPU collection and therefore it is QUITE different <to me... < Enrico, What your saying is you want a real Intel 1974 C8080D date code part! That's the commercial grade cermet package part that was the initial offering. Not an AMD, NEC or some dozen others, not all identical. On the other hand if you really wanted all of the various permutations of the 8080 and there are at least 4 or 5 (all pre 1979) I know of. You'd have to consider the 8080a a find as that is still pre '79 design! You have to qualify the vendor and mask set used of or if it was a reverse engineerd design like the NEC parts the 8080, 8080a and 8080af. Of course there were subtleties like the round lid uPD8080AFD or the square. So if you are going to preserve history, you have to be a lot more specific. Or otherwise an 8080A is really then just another 8080! It's the specific part, vendor and die level aspects of the history you loose by collecting those 40 pin slabs of plastic or ceramic indiscriminately. FYI: the MDS I have has a intel 8080 cermet late 74 date code nonstandard branding hand written part number. It appears to be a engineering sample marking. I also have several dated copies of the 8080 and NEC 8080 parts as they were different both in packaging and specifications. Never minding the other intel one from my altair(early 75). The 6800D1 board I have has a MC6800L, that's the cermet 1mhz part circa 1976(august if the datecode reads right). Since I was designing with and using these parts I retained samples that I never threw out as I figured some day I may use them again. they are also part of the collection of processors that includes the DEC T-11 single chip version of the PDP-11 chips I have with DC310es60 (engineering samples 4 of them). One of the ES parts is in a internal DEC demo/proto board. Then there are the pre '79 SC/MP, cosmac, Intersil, TI I know a bit about the history as I was one of the now older hackers from then!

Bogus CD drive

[11/34A] ARRRRGH!! <sound of head banging on wall>

by dseagrav＠bsdserver.tek-star.net

The BUS ERROR wasn't from the card not being installed. I reinstalled everything, and it refuses to boot. Apparently, I've snipped the wrong wires on the UDA50 slots. Or forgotten to plug things in... No, that's not it. EVerything's plugged in, the lights on the UDA strobe, I've cut the wrong pins and boogered this up worse. I really should stop destroying these machines and just pass them on to more capable people... But I like them too much. Where are the pins I am SUPPOSED to have clipped? I'll rejumper the old ones, it doesn't look hard...

Docs wanted: Scantron OMR units

by jimw＠agora.rdrop.com

Snickering quietly at the visions of people fleeing in terror and revulsion... B^} I'm seeking some docs on a couple of recent additions to the collection. (be kind, they both have microprocessors so they at least kind of fall into the charter) I've rescued a Scantron 888MP test scorer OMR unit and a model 8400 (option 40) OMR page reader, both (of course) with no docs, information, or software. (for the 8400 at least, the 888MP is a stanmd-alone) So... after the prerequsite inquires toward Scantron (which so far have netted a couple of nice catalogs, and an offer to sell me the latest/neatest units, but nothing useful for what I've got... I turn here... So... if anyone has (or has access to) spare manuals (or copies thereof), I'd appreciate hearing from you... Hey, this could even be an opportunity to dump that carton of old Scantron (bubble) forms you have been using for note pads and connect the dot (bubble?) games! <G> -jim --- jimw(a)agora.rdrop.com The Computer Garage - http://www.rdrop.com/~jimw Computer Garage Fax - (503) 646-0174

It is not IBM compatible, though - neither the architecture nor the disk format - so attempting to boot from a PC disk won't achieve much. I have an Act Sirius-1 which I believe is a re-badged Victor 9000. If the worst comes to the worst I can attempt to copy some disks and snail-mail them to you.
