The manual I have is in the form of a large format (8 1/2 x 11) paperback, 237 pages with the authors of the software listed as Dale Buscaino and Scott Daniel (apparently aka Progressive Software Design) with the authorship of the manual given as them plus Michael Shrayer and Harvard Pennington ("TRS-80 Disk and Other Mysteries" and president of IJG). It was published in 1983 by IJG Inc. (the Thoughtware Company tm) of Upland, CA. A Google search revealed a review from 1984 by Betsy Staples, an editor at Creative Computing. It was a rewrite rather than a translation of the original code and had some expanded features and additional support programs. Bob Stek Saver of Lost Sols

HP 2784B Paper Tape Reader on ebay

by xds_sigma7＠hotmail.com

Well I wouldn't bid on it because I don't need 2... If someone does get it, I have the manual. And, FWIW, it is not a 2784B, it is a 2748B... I dunno what a 2784 is, but it ain't a paper tape reader...

Mode 0 is 80x32 mono, with no gaps between lines. You're probably thinking of Mode 3, 80x25, with gaps between the lines; also mono but you can set the foreground and background to be different from the gaps. > Something that is missing from todays machines.

I don't know about the rest of the list, but I don't want another MV II badly enough to go to Indonesia for it!

You could scrap a number of mice for the optical sensors ( two for each axis, 4 total per mouse ) or you could buy photo transistors from Jameco. In a pinch, the clear lensed LED's make reasonable detectors. Use a little imagination.

I noticed that one a couple of days ago and was somewhat interested. But it is listed at 40lb so shipping would probably cost more than the opening bid, plus it looks like it needs some weird type of V35ish connector which might be difficult and/or expensive to source if you don't happen to have one already. Has anyone built their own optical paper tape reader?

old test equipment found

by carlos_murillo＠epm.net.co

I've recently come across three pieces of vintage test equipment; a Precision brand signal tracer, a Heathkit audio analyzer and a Radiometer Copenhaguen model HO-32 beat frequency oscillator. Here are some pics; the ones marked "small" are 60KB on average and the others are roughly 600KB and highly detailed: http://nazas.autonoma.edu.co/heathkit_audioanalyzer-small.jpg http://nazas.autonoma.edu.co/heathkit_audioanalyzer.jpg http://nazas.autonoma.edu.co/heathkit_audioanalyzer_bottom-small.jpg http://nazas.autonoma.edu.co/heathkit_audioanalyzer_bottom.jpg http://nazas.autonoma.edu.co/heathkit_audioanalyzer_top-small.jpg http://nazas.autonoma.edu.co/heathkit_audioanalyzer_top.jpg http://nazas.autonoma.edu.co/precision_tracer_model_st-22.jpg http://nazas.autonoma.edu.co/precision_tracer_model_st-22_small.jpg http://nazas.autonoma.edu.co/radiometer_copenhagen_ho32_BFO-small.jpg http://nazas.autonoma.edu.co/radiometer_copenhagen_ho32_BFO.jpg The Heathkit audio analyzer passed visual inspection (pretty clean and caps looked ok) and I powered it up. It seems to work. The Precision signal tracer is not working; somebody took off the rectifier tube/valve and soldered a couple of diodes; I suspect that at least one filament is open (pins 3 and 4, right? It's been a long time since I last worked with tubes). I certainly want to restore it; I like the "magic eye" indicator tube. The Radiometer Copenhagen gear I haven't powered up because several large electrolitic caps show signs of deterioration. The construction of this last device is outstanding in terms of the quality of the components. The Heathkit is pretty good too; not so the Precision signal tracer. Now the question: can you please take a look and see if 1) you have docs for any of these, 2) might guess what the operating procedures are and what the controls and connectors are for? Some I can guess, others I don't know. regards, carlos. -------------------------------------------------------------- Carlos E. Murillo-Sanchez carlos_murillo(a)nospammers.ieee.org
