I was offered one several years ago. I'm not sure of the configuration, but the storage was 2 x 8" floppies and I think it was a lot cheaper than a small PDP-11. Unfortunately, I didn't appreciate what I was looking at, turned down the (free) offer, and apparently it ended up in a skip (dumpster).

I do every day, and I can tell you that none of the ones I deal with -- and I mean *none* -- know what a ROM is, or what BASIC is. "No ROM BASIC" tells you, Tony Duell, what happened, but for the vast majority of users, it doesn't mean a thing. Glen 0/0

VAX 4000 Power Cord (BA440)

I remember a couple of months ago there was discussion on the proper cable for a BA440 power supply (normal North American three prong power cord but with a notch where it plugs in to the power supply).

Radio Shack Armatron NEW page

by mythtech＠Mac.com

Ok.. the May 85 Radio-Electronics pages have been moved. The (or should I say A, since others are welcome to mirror them) page to download them is: <http://www.mythtech.net/armatron/> There are 6 pages, you can DL them individually (approx 150k each JPEGs), or you can download the single PDF of the pages (approx 5mb). They can stay here until someone that owns the copyright to them yells at me to take them down... or until further notice (which means, by tomorrow, I will have forgotten they are on my site, and they will end up being there pretty much forever). If anyone wants the original TIFF files, let me know. There was no real difference between the TIFF and the JPEG, except that the JPEG is about 4 times smaller. I have no plans on posting the TIFFs, but I will be archiving them to CD if anyone decides they want them. Thanks go out to Mike for taking the time to scan these, and work with me to get a good copy of them. -chris <http://www.mythtech.net>

Bad bad DECstation

by optimus＠canit.se

Our DECstation 3100 has been in a sad state recently. Both the monitor (that old monochrome thing without a stand which was used with the VS2000 amongst others) and the keyboard (LK201) had given up the gist (the monitor would just make a flickery sound, without the CRT coming alive, the keyboard didn't blink and the console would blink "??" when it reached test 3). I plugged in a Nokia monitor, which worked, if you can live with the green picture, and another LK201. That worked for a while, but when I managed to boot it (NFS wasn't so cooperative this day), and reached X, the mouse just stopped moving after a while. I rebooted it, and suddenly this keyboard had died as well. What the hell is going on? Is it possible to save the LK201s? We're running short of DEC keyboards as it is, and we certainly don't need this. -- En ligne avec Thor 2.6a. If the designers of X-Windows built cars, there would be no fewer than five steering wheels hidden about the cockpit, none of which followed the same principles -- but you'd be able to shift gears with your car stereo. Useful feature, that. - Marus J. Ranum, Digital Equipment Corporation

8080 vs. 8080A

by ajp166＠bellatlantic.net

Track the clock through the logic... there is a divide by 2 in there. Also the 9080 250ns part was late in the game and hard to find. If you want an 8080 that was really fast use a 8085-5 (5mhz) or the later 80c85-6(6mhz). the latter was a nice part as it was CMOS. I still have a potload of 8080s and 8085s and my design favorite for small systems is the 8085 over the Z80.

Hello, I just picked up a 9K 847S, upgraded to H50 with two SCSI-buses, one mux panel, a few disks and 384MB of memory (hmmmmm...).

A few questions: a) Introduction date ? b) Where can I get HP-UX 10.x cheaply :)? (ie. for free) -- jht

I believe that qbasic was included in some older nt and win9x installations only as support for "edit"; i.e., you typed "edit autoexec.bat" and the qbasic editor would be the actual invoked program. carlos.

So I dropped by the computer shop today and they had a Tandy 1800HD laptop for $10. I grabbed it. It's in excellent condition. Unfortunately, someone stole the power-supply... Any idea where I can get one? Also, were might I find a scanned manual for this thing? Blair

Boot Disk Needed

by mythtech＠Mac.com

>/U (do a REAL format) is faster for you than >/Q (DON'T do a real format, just write an empty directory) ?? > >Would you care to post some measured times for how much faster it is? Speed will be HIGHLY dependant on what size disk it is. A 360k disk formats with /u fairly fast, and although it is STILL quicker to do /q, it isn't a huge difference... however, when doing a 1.4 disk, it cam be the difference between over a minute and under 10 seconds. /q is basically the same as doing "del *.*", it doesn't reformat the disk at all, it just rewrites the FAT so the disk thinks it is blank, the fastest way to clear a disk is "format a: /q /u"... UNLESS there are only a few items on it, then del *.* might edge it out Also, with all this /u business... be careful when doing that on 5.25" disks in a high density drive. If you put a DD disk in, and do format /u, it will NOT warn you that it is going to attempt to format a DD disk as HD. In MS DOS, when you format on a HD 5.25 drive, it automatically tries to format HD... you need to specify the format size (or use /4) to format 360k... leaving off the /u will warn you that the format is different then what you are about to try. Unfortuantly, leaving off the /u ALSO fails to remap bad sectors, AND saves the unformat info adding a few more seconds onto the disk format. None of this warning business applies to 3.5" drives, they will detect the HD vs DD disk, and format correctly... so with those it is safe to always use /u if you want to. -chris <http://www.mythtech.net>

Odd VT100 question

by healyzh＠aracnet.com

OK, I'm thinking of doing a wierd mod on a VT100, just how much room is inside one of them? I need room for a 7 1/2" x 9" x 2 1/2" board (the 2 1/2" is thanks to the heatsink and RAM), and would also like to be able to fit in a smallish 250W PS (3 1/2" x 5 1/2" x 6"), and a 3 1/2" HD. I've got 2 or 3 VT100's, but they're so buried it's going to take a lot of work to get to them so was hoping to get an idea if there is room first. Basically I'm trying to build a PDP-10 into a VT100 by using an Intel D810EMO MicroATX board. Zane -- | Zane H.

Power connectors

by tniemann＠msn.com

Hans.... I may be wrong in my explanation to the following question you posed but I will give it a shot.....You said: I don't know any reason why the system has to be keyed, I always assumed the US development of keyed plugs was triggered by old DC systems (since in DC Eq. it is necersarry to know the orientation), but not a new addition. Strange, we dropped all orientationwhen switching to AC (with Protective Ground). Could anyone give give a reason why the system has to be keyed _IF_ a Protective Ground is included (other than define the Protective Ground pin) If you hook an scope up circuit such as a TV and hook the ground probe up to signal ground but you have the plug reversed the circuit will short out and you will blow the device you are testing. That is because you just provided a current path to frame ground for the signal which you thought was signal ground. TV repairman who have used scopes have done this more than once.

FT: Alpha Architecture Docs

by cmcmanis＠mcmanis.com

The Alpha was started by DEC in 1988 as a replacement for the VAX, it extends the address space to 64 bits and switches from a CISC architecture to a RISC architecture. I've got a copy the Alpha Architecture Reference Manual (AARM) and the Alpha Architecture Handbook (AAH) which combined give you everything you need to know about the Alpha. They're extras. I'd like to offer them in trade to anyone who has EITHER: KA640 Technical Manual KA680 Technical Manual Also published by Digital. --Chuck

Anyone ever heard of a Canon BX-1?

by greg＠cosc.canterbury.ac.nz

I have recently acquired a Canon BX-1 Desktop Computer. It's a self-contained unit incorporating an alpha keyboard, a single-line alpha display, thermal printer and 5.25" disk drive. From the markings on the keyboard it seems to be programmed in some dialect of Basic. Does anyone know where I can find any information about this machine? A web search turned up exactly one page mentioning it, which didn't tell me much. It didn't work at all when I first switched it on. I found and repaired a fault in the power supply, but that doesn't seem to be the end of its problems. At switch-on, it beeps, and then starts flashing a row of up-arrows in the display. There is *almost* no response from the keyboard, except that after about 20 or so keystrokes it flashes something like KEYBOARD OV'FLO very briefly and then goes back to the up-arrows. Is there anyone out there with any experience with one of these things who can tell me whether it's trying to signal some sort of error condition with the up- arrows, or is it just totally insane?

Altair 8800a on EBAY

by ajp166＠bellatlantic.net

Hi, Please understand I dont collect for economic gain. I'd have to hit the big one to pay back for some of the machines I built new back when. I collect to have the machine I could not afford back when but wanted to experiment with. So happens along the way some of them became interesting as so called rare items. To me my Altair was a relly poor machine and the NorthStar I replaced it with was far superior, yet the first is collectable even though it was truly a peice of junk compared to even the IMSAI. Anywho I'll look when time permits.

I believe the Z80B is 6MHz and the Z80H 8MHz. SGS-Thomson list them as 6MHz and 8MHz now, but IIRC the Z80H was originally 6MHz.

I imagine the switch is to select different code versions. The thing I like most about the Spectrum service manual (apart from the inclusion of a proper schematic and other diagrams) is the fault-finding list. Most such lists begin with mundane things like checking the fuse. The Spectrum begins with: "TV appears dead. Smoke appears" and describes additional symptoms as "TR4 shorted. TR4 blows again". -- Pete Peter Turnbull Network Manager University of York

blank 11/16" paper tape rolls available.

by f.bonomi＠agora.stm.it

Hi all If anyone is interested I have some rolls of paper tape available for shipping cost, if anyone has a good use for them (i.e. anyone has a punch in need of paper) Must be rather standard, where used in a Telex, but due to my ignorance in tape I will try to describe as precisely as possible. characteristics: Tape width 11/16" (ca 17.9 mm) tape length: unknown (should I unroll one of them ?) color (white-ish) Rolls diameter abt 7"" (18 cm) The "hole" of the rolls (about 2" or 5 cm in diameter) has a "square wave" profile to be better mounted. Anyone interested? Only drawback: I am in Italy, shipping will not be cheap... ciao Francesco

Appropriate for early embedded stuff. that is the exact reason why the 8085 was successful. As to the comment about the SIO/SID pins they were used by the TU58 for serial data and were very hand for when a few bits of IO were needed for simple things. Allison
