<I finally picked up the DECMate III that was at my uncle's house. The WPS <binders and software got thrown away, but I suppose I could download that <stuff from SunSite. I have been told that this is a PDP-8. Is it possible You can get os/278 as well. <to use 8" disks with this? It only has a dual 5.25" drive (RX50?). Yes they are RX50s. There was no provision for 8" disks on the DMIII. FYI: 8" RX01 were 512blocks (256k), 8" RX02 were 1000blocks(512k) and RX50s are 800blocks (400k). So the 5.25 media is really nicer. <Forgive me, I am not familiar with DEC machines. Oh, and one more thing. <Can the screen/keyboard be replaced with a PC running a terminal emulator? <The screen is attached via a 15-pin cable but otherwise resembles a <VT-220. Thanks. No. It expects a VRR201 monitor and a LK201 or LK401 keyboard. There are two serial ports, modem and serial printer. The chances of getting those are really good around here (eastern MA) and if by may you don't have one the MIT flea is a good shot. Allison

I need a ST-419 hard drive

by jeff.kaneko＠juno.com

Hey Joe! I went down to the junkyard near where I worked, and managed to turn not one, not two, but *three* HP 9133XV's! There were also "V"'s a "D", and an "H". I grabbed one of the XV's, and plan to test it with my 9816. If the platters are in good condix, would you be interested? I could even just pull the HDD unit (14.8Mb :) and send *that* if you like!

The manual I have was a 3rd edition dated 1982, (the 2nd 1981) so he must have sold quite a few of these. The company was known as CompuKits and TMK was marketed widely in N. A. His name IIRC Was Jim Reiss. I'll have to see if he's still at my old alma mater. It's possible the one you're talking about was a later model if he joined the Uof T faculty. The built kit looked really neat. Everything was entered from the console by toggle switches or pushbuttons and it had LED indicators. It had provisions to expand memory allowing use of Motorola's MIKBUG monitor ROM to interface with a T-T or RS232 device as well as a provision to add 256 bytes of non-volatile memory. You could expand memory up to 8k x 8 static ram and suggests you use the less expensive and smaller chips like the 2102 rather than the 6810s used in RAM 1 and RAM 2. Would be an interesting project to build one, if I ever get the time. ciao larry lwalker(a)interlog.com

question about viruses

No...

Call A.P.P.L.E.

by dpeschel＠u.washington.edu

I couldn't send e-mail to you. > book. Still, in my paper, Apple Worm (published in the November > 1986 issue of Call A.P.P.L.E. magazine - as the cover story), I > make reference to the book. That's a name I haven't heard in a while. What was your involvement with A.P.P.L.E.? I grew up with the Apple ][. (I mostly played games, although I wrote a few interesting programs which I may still have.) I've lived in Seattle for the past 16 years, and my family belonged to A.P.P.L.E. We didn't go to many meetings. I was the main computer user in the family, but I was much too young to drive; my mom was almost totally uninterested in computers at the time, and my dad was only slightly interested. (Admittedly, I still can't drive, because my vision is not good enough, but I think you see what I mean. And I only got one good game out of my parents, which I let them sell -- see below.) Still, at one time we had a stack of magazines, a lowercase chip for our Apple ][+, something else (came in a plastic bag with a white manual, like the lowercase chip, except the title was in yellow instead of orange... maybe related to accounting? I don't remember), The Graphics Magician (?) and its companion program, The Mummy's Curse, and assorted public-domain disks. This was all from A.P.P.L.E. I'm not nearly as Apple-centric as I used to be (for example, I now appreciate the design of the Atari and Commodore, which I basically sneered at when I was younger; and I'm experienced enough to understand the ]['s flaws). But I still feel fond about my Apples. The access to machine language is still a strong point, the disk system has an admirable design, and some of the software produced for the ][ still amazes me. And we sold the software we had and now I'm looking for some replacement items. :( -- Derek

Classic Calculator: Value?

by kyrrin＠bluefeathertech.com

Ok, so I'm not a big calculator collector. ;-) However, I did pick up a neat little box recently, one that I'd like to (a) find out, ballpark, what similar units have been going for on the swap market, and (b), use it myself for a while. What I've gotten is an HP-65, in pretty darn good shape, in its hard case with a bunch of the program pacs and all its manuals. I know I've got at least one, possibly two EE pacs, a stat pac, and others that I've not looked at just yet. The batteries are dead, of course, so I think I'd like to get them replaced at least. Are they generic NiCds or what? Thanks in advance. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner and head honcho, Blue Feather Technologies http://www.bluefeathertech.com Amateur Radio:(WD6EOS) E-mail: kyrrin(a)bluefeathertech.com SysOp: The Dragon's Cave (Fido 1:343/272, 253-639-9905) "Our science can only describe an object, event, or living thing in our own human terms.

Quick and easy way of removing a few bytes, that's all. As I mentioned previously, there are companies which specialize in data recovery from disks... and the disks don't even have to be operational.

Anyone have any boards made by CESI in their PDP8/e ? I have a bunch of advertizement fliers describing many of these boards, if somoene is interested in the information. They made a replacement cpu board and quite a few other boards. -Lawrence LeMay
