HP 935

Either that or they left out the "8" in 9835 and it is a desktop computer, possibly with a one-line LED display (9835B) or with a CRT display (9835A). Well, those are my guesses. I'm interested in hearing how far off I am. -Frank McConnell

old SCSI controller

by rexstout＠ptld.uswest.net

The only things I know about this board is that it's a SCSI controller, and it's BIG. It's about 10"x12", has an 86-pin edge connectr on the bottom, two 50-pin edge connectors on the top, and uses eight 2651 SCSI chips. It's labeled "DATASTREAM ASSY 100716 REV A". Does anyone have any idea what this is for? TIA -JR http://members.tripod.com/~jrollins/index.html - Computers http://www.geocities.com/Area51/Lair/1681/ - Star Trek

Recent Finds...

by foxnhare＠goldrush.com

This weekend's recent finds netted me two books: The first is called Computers and Man, by Richard C. Dorf, published by Boyd and Fraser Publishing Co. in 1974. It looks like it could have been a college text at one time. The real notable part is it is loaded with alot of pictures of earlier machines and computers from the late 60s and early 70s (such as a picture of an IBM 2321 strip file, which I think was mentioned here a few months back.). also a good description of core memory (which I have been searching for to go with my core memory board I won at VCF.) The other, which may be a duplicate (for me) was PET/CBM BASIC Programming and Applications by Gene Streitmatter and Larry Joel Goldstein published by Brady Books which had an unlabeled 5 1/4" disk shoved in it, the disk contained a few examples from the book written by the last owner (for the PET)... You never know what you may find though. Not as bad a Programming books of the time go, even some nice type-in games in the back.

Weekend Additions

by dastar＠wco.com

Well, I thought I'd trumpet my trophies from today's hunting since I haven't done a trip like this one in a while and it was fun. Nothing really amazingly special today, but there were some nice finds. First stop: Computer Recycling Center Commodore Colt (PC-10C) - the Commodore IBM PC compatible, kinda neat. Has a WD hard drive inside (don't know what size) Radio Shack CoCo1 with the old-style (original) keyboard. I believe this is a 4K model. Came with the RS Modem I and a manual set plus some carts and a bunch of tapes with instructions Radio Shack Line Printer VII Zenith Data Systems Portable - this is the OEM'd Morrow Pivot Portable Everex external tape backup - this is cool...it uses cassette tapes for (apparently) 40MB backup. Coincidentally I found another one of these at stop #4 with a cassette. The cassette looks like your standard tape cassette but it has a notch on the tope of the casing in the middle. Can this drive use standard cassettes? It apparently plugs into the external floppy connector of an IBM PC Mac SE with 4MB RAM and 20MB HD Bunch of books, cables, Apple II software, other miscellany Total: $50 Second Stop: Surplus Store Atari 600XL with Atari 1027 printer (2) Lobo 5.25" drives for the Apple II (of course Marvin knows these were manufactured in Santa Barbara, CA!) Apple //e numeric keypad, joystick (2) Apple //c power supplies Miscellany Total: $30 (haggled down from $45) Third Stop: Thrift Store #1 Mattel Aquarius with Mini-expander and two game controllers in excellent condition (my first computer!) Atari 800XL Total: ~$15 Fourth Stop: Thrift Store #2 Burroughs C-7400 Electronic Adding Machine - I don't know if this should be called an adding machine or a computer. It seems to have some sort of computing ability. The keypad has this overlay with commands such as "GOTO", "IF" and "GOSUB" printed on it. I haven't fired it up yet but it has a one line LED (LCD?) display. Looks very neat. I don't normally collect adding machines except when one really jumps out at me. Any info? Data General External 5.25" Floppy Drive - I believe this drive was specific to the DG1 laptop. The funny thing is I just recently saw a photo of it on a web page and was thinking "Hey, I want one of those" A whole OS/2 library of books (like 10 volumes on OS/2 including developer manuals for Presentation Manager, etc). Total: ~$15.00 Fifth Stop: Surplus Store Northstar Advantage in excellent condition Panasonic Portable Data Terminal - similar to the TI Silent 700 but a little more polished Televideo PC-605 - this is a more IBM compatible model of the Televideo PC. This one apparently has a color CGA monitor instead of the more standard monochrome display. It also is supposed to have a PC compatible BIOS and can thus run some PC apps. It also has a HD (probably 20MB) Corvus Systems Hard Drive unit - I believe this goes with the rest of the Corvus Concepts computer. It has several connectors on the back labeled "Processor", "Drive"...it also has one labeled "VCR" and a video IN and OUT jack. McFrank, this is so you can backup to a VCR right? Misc. MicroPro software packages (CalcStar) Misc. books: Rexx, 8080/8085 Assembly Programming Total: $80 Grand Total: ~$190 Total spots visited: 5 Total Elapsed Time: 7hrs Deal Scale: 4 (1=Bad Deal...10=Great Deal!)

front panels

by allisonp＠world.std.com

<>> panel. Does anyone remember other front panel S-100 cards besides MIT <>> IMSAI, Ithaca, and Wameco? Wasn't there a Byte-8 sold by Olson <Electronics <>> for a while that also had a front panel? < <>Yes, the Byte-8 had a front panel with, I believe, a hex keypad and a tw <>digit 7-segment LED display. Godbout. Equinox_100. <Was that just a display driven from a boot ROM or was it a real front pan <with displays directly driven from the bus, examine/deposit, single step <etc.? Usually a hex keypad meant a simulated front panel (CPU actually <running a debug program in the boot ROM). A true front panel needed 16 L <or 4 hex digits for address, 8 LEDs or 2 hex digits for data, and at leas <status LEDs for bus signals (SINP, SOUT, MEMR, INTA, etc.). Most were "simulated FP" though most offered better than real front pannel abilities. A few were hybrid, IE: the leds really did indicate what was on the bus and the cpu only ran the rom code needed to perform the needed actions and stopped. <All the panels <I have seen also had an extra 8 LED latched output port and sense switch <input port. Altair compatability hack. The sense switches were also port 0FFh so the software could read them. Allison

HP 7958B

by healyzh＠ix.netcom.com

Today I picked up a HP 7958B unit which contains a "Bauart Gepruft model 97533-60051" Hard Drive. It is my understanding that this Hard Drive is an MFM Hard Drive, and I got this thing expecting to be able to find enough info on the net that I could hopefully fake my way through formating it for one of my MicroVAX's. No such luck, I've been able to dig up a big fat nothing on the net. Does anyone have any info on these things? I gather they were used with HP9000/300 systems. Zane | Zane H.

IBM Techref

by maxeskin＠hotmail.com

Tony, you mentioned that a lot of info was mentioned in the IBM techref, on the AT in your case. What is the kind of size of this set, for the AT let's say, and does anyone have extra copies? What about XT? (I have the quickref to it already) ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
