I have some pictures I can scan if anyone cares. Now that you've said it, I do recall Dmitri called it the "Buran"; it was some other reference lost to memory that called it the "Snowflake"...

HP-1000E PSU

I spent some time staring at the manual convincing myself that there were no directions for testing the power supply with a less expensive load. I suspect HP's thought was that they would probably have the service contract, and if the power supply was going to fail in a way that fried other stuff then it would have already fried the other stuff by the time the service call was placed, and the CE would have those boards in his kit too. > Incidentally, am I the only person who finds the faultfinding flowcharts > (like the ones that HP published in a lot of their service manuals) to be > fairly useless? You know the ones that say > 'Is there a clock at pin 3 of U5 > Yes : Is there a high level at .... > No : Replace U5, X1, C1, C2 in order.' It looks vaguely useful for people like me: a programmer with soldering iron type who appears to have a read-only mind w/r/t the more interesting bits of electronics. At least it would get me to a board that I could then try to trace out and ask questions about. That's why I pointed rdd through the first couple of bits -- they will tell whether the power supply is alive at all and whether the fundamental adjustment has any effect. Unfortunately I don't think I have schematics for 1000s or 21MXs. Well, not complete ones. Tonight I picked up the 21MX E-series Installation and Service Manual instead of the 1000 E-series one. Guess what, it's got appendices, including Appendix B with schematics for the operator panel, 16K memory module, 8K memory module, and 4K memory module. Not the power supply though. Hmm, on the other hand I'm not sure it would matter, it looks like the power supply is different in the 21MX -- instead of board with daughterboards, it's got an upper and a lower board. Guess the difference is deeper than the front panel silk-screening. -Frank McConnell

Review of Apple Confidential: The Real Story of Apple Computer, Inc.

by vcf＠siconic.com

I've posted a review of Apple Confidential: The Real Story of Apple Computer, Inc., to the VCF website. http://www.vintage.org/cgi-bin/content.pl?id=003 It's a good book and I highly recommend it, especially if you're an Apple fan.

More Stuff

by foo＠siconic.com

More from the same issue of Computers & Electronics (Nov/82). Has anyone ever heard of this machine? Introducing a Brand New Microcomputer: Venture VENTURE is a single board computer that is an adventure for the hobbyist. It is a learning training computer as well as just plain fun for anyone who wants to get into a state-of-the-art computer at reasonable cost. VENTURE comes in kit form or fully assembled and tested. You can get it in its minimum configuration for as little as $195.00 or take it all the way to floppy disks and voice. It can be expanded as a kit or fully assembled, at your own pace and choice. VENTURE is a 16" by 20" main board with separate ASCII and HEX keyboards. It runs fast, almost 4 MHz and has the capability of putting 1.5 megabytes of RAM and ROM on the board along with a variety of inexpensive options. On Board Options: 16 channel A to D; 5 slot 60 pin bus, 2 serial ports, parallel ports; 4 video options incl. color, 52K RAM, Votrax voice synthesizer, sound generator, EPROM; Full Basic, disassembler, editor, assembler; metal cabinet, additional power supply, ASCII keyboard, real time clock calendar. Expansion Options: Floppy Disc, EPROM Programmer, light pen, universal user programmable music, sound board, high resolution color/grayscale pixel mapped video board, General Purpose Instrument Bus, 8088 co-processor board. Minimum VENTURE System: $195.00 Kit includes CPU and control with 4K of RAM, 1K of scratchpad, 2K monitor, 1861 video graphics, cassette interface and separate HEX keyboard with LED displays for address and output. Power supply is included along with 2 game cassettes, The main board is 16" x 20" and includes space for all of the previously dicussed on-board options. Full on-board expansion can be completed for under $1000.00. I want one! The ad is from Quest Electronics in Santa Clara, CA. They also sold kits for the RCA Cosmac 1802 Super Elf, the Rockwell AIM 65, as well as a modem kit, a Z80 Microcomputer kit, and various ICs and such. The ads in the back (the low budget ones) have an even neater array of single board computers being sold by what would seem to be hobbyists trying to sell their creations in the commercial arena. There's an ad for a 68000-based singleboard, a port expander module for the HP-41, plus various add-ons for various computers of the day (Sinclair, Atari, TRS-80, etc). Finally, there's a small add for a IBM Selectric-to-computer adaptor to use the typewriter as a printer. Anyone ever hear of Synchro-Sette magazine (for the Sinclair ZX-81, TS-1000)?

I'm bidding on a DECwriter III so that I can have something I can load greenbar into on the Prime; I also bought a wide-carriage Imagewriter for the same reason. That gives me a backup, I guess.

Yeah, the phrase "line printer" will probably elicit as much of a furrowed brow from these newbies as would "unit record". > Hopefully line printers and wide dot-matrix printers aren't on their > way to becoming obsolete. Well, both printers alluded to above were found on E-Bay, so they must be rare.... :-) -dq

Well, okay, the 2CV, but > I did say *car*... :-) Yup...look at the Firebird or the Camaro. How many completly different body styles from the late 60's til now? Five? Six? And we don't even want to talk about what happened to the Chevelle and the Nova. The only similarities between the old & new of those models are in the names. -Dave McGuire
