I remember scenes like those from when I was a kid and we'd go on field trips to places like Rockwell and Battelle. -ethan

Univac 422 sighting

by cclist＠sydex.com

Just happened to see one on an ancient rerun of the "Patty Duke Show". Although it was a "training computer", it still had 512 words of 15- bit storage and an instruction repertoire of 61 instructions. (6 bit opcode+9 bit address). Ed Thelen's list gives it as 1963. Power consumption, from the manufacturer's brochure, was 500W, with a 115VAC supply. Thelen gives it as 1.13KW, but I suspect that the difference is in the I/O device (typewriter, paper tape punch). Given the modest space and power requirements, would the 422 qualify as another one of the first minicomputers? Cheers, Chuck

Square D Sy/Max 8010-SPR-300 Programmer rescued

by wgungfu＠gmail.com

Hey all, just rescued a Sy/Max Programmer today. Same model as the following: http://www.maraindustrial.com/catalog/8010SPR300.jpg Unlike that pic, everything looks in great condition. Thought I'd check here for any interest. Looking for trades or cash (which will ultimately go towards other equipment anyways). Marty

Display peripherals for PDP-10

by legalize＠xmission.com

Do any of these still exist? >From 1970 PDP-10 reference manual, part 7, pg. 631: "346/ 340B PRECISION' INCREMENTAL CRT DIS- PLAY: plots points, lines, vectors, and char- acters on a 9 3/8 in. square raster of 1,024 points along each axis. 1 1/2 us is required per point in vector, increment, and character modes. Random point plotting rate of 35/is. A 370 high-speed Light Pen is included. 342B CHARACTER GENERATOR for 346/ 340B 348/VR30 PRECISION POINT PLOTTING DISPLAY: operates at a maximum plotting rate of 20 KC or one' point every 50 ,ts on a 9% in. x 9% in. display area. Number of addressable points along each axis is 1024. A 370 high-speed Light Pen is included. ' VP10 POINT PLOTIING DISPLAY CONTROL: operates at either of two maximum' plotting rates. Low rateis 10 KC (one point every 100 ns). High rate is 50 KC (one point every 20 Ms). Number of addressable points along each axis is 1024. Control interfaces to. a cus- tomer supplied oscilloscope (Tektronix Type RM503 or equivalent) or to a CRT display. 370 HIGH SPEED LIGHT PEN: for use with VPl0." I'd never heard of there being graphics display peripherals. Looks like these are storage tube technology based, even though the description says "raster". I think here they just mean the addressable range of points on the tube. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>

David Ahl sez: Phila. Computer Music Festival remastered onto CD

by evan＠snarc.net

Got this email from Dave Ahl tonight: -------------------------- Hi Evan: At VCF last summer, I mentioned the Phila Computer Music Festival (Aug 1978) and asked if anyone was interested in a CD of it. Quite a few hands went up. So I finally took the time to make a CD of the Festival. Unfortunately I had to start with the vinyl record because the tapes had long since disappeared. But in remastering it, I was able to balance the tracks (on the original, the left was at a higher volume) and also adjust the volume of the various pieces to make them more of less equal (there was a 50% difference on the original). So now I have remastered CDs available with all the original jacket and liner notes (slightly re-edited) for $7.95 postpaid in USA. Maybe you could put out a notice to the VCF list. Complete Info and how to order can be found at http://www.swapmeetdave.com/PhilaMusic/

HP HPIB chips

by ard＠p850ug1.demon.co.uk

A week or so ago there were a few messages about the HP 'Medusa' HPIB chip. While looking for indormation on the custom chips in the HP printer I'm working on from time to time, I cam across some comments that might be applicable. The HPIB interface chip in the HP2531 printer is called 'Phi'. According to HP Jorunal July 1978, it is a silicon-on-saphire CMOS device. It's pacakaged in a 48 'pin' leadless ceramic package, and has the number 1AA6-6004 The Medusa, packaged in a 48 pin DIL package, seems to be a closely related device. The pinot is in the same order, for example. This probably explains the rather curious numbering of the data bus pins on the Medusa (D0, D1, and D8-D15, with D15 as the LSB). The best reference I've found so far on this is the reference manual for the HP12009A HPIB interface for HP1000 machines. It's on http://www.hpmusuem,net. THe earlier version of the manual there covers the Phi-based board, the later version the Medusa-based one. They are very similar.. -tony
