A copy of Donald Davis' space art that he placed in the public domain in February 2007. His website is here.

Burroughs Corp. Nixie datasheets that don't fit anywhere else.

Old Intel bubble memory datasheets and documentation. This was a non-volatile magnetic memory technology that came and went in a few years in the late 1970's/early 1980's. I wget'd this data from a personal website at www.xs4all.nl and neglected to note or even contact the author. If you have information on the original poster please let me know.

Burroughs Corp. Nixie and Panaplex display data and application notes. You'll need this stuff if you want to use this old display tech.

My semi-extensive collection of electron tube (vacuum tube, aka valve) catalogs and datasheets, from 1958 - 1961, scanned and indexed. This does not include any radio or TV tubes, only industrial types.

Really old integrated circuit and transistor data sheets. Unlike tubes, the sheer number of unique components confounds easy documentation; even by the mid 1960's there were thousands of vaguely distinguishable, poorly documented, crappy parts with more specology than spec. Here's a few, for amusement purposes.

Oddly, it's sometimes hard to find basic specs on old miniature lamps; here's a simple CRAMER catalog page from the 1970's.

A random, unorganized list of technical catalogs from the late 1950's that I will not index or scan. If you need any of this data, yell.

Photomultiplier tubes are fun; detect single photons at home! Here's a nice practical PMT circuit and theory page, by Charlie Thompson of Buda Seismic Observatory. I hope it's still there when you click. Complaints to /dev/null. Personally, I would use a negative HV supply, put the anode and signal pickoff near ground potential. I made a backup copy of this page here just in case.

Here's a datasheet for the long-obsolete 7441/74141 Nixie driver chip from an early 1970's National TTL databook.

While working for Phoenix Software Associates I ported MSDOS to the Z80-based Otrona Attache 8:16 (Mike Aronson fit an 8086 into the printer option slot!). Here's a copy of the floppies I had for mine.

My foolish, and now dwindled, collection of radiacs and dosimeters.

Some scanned images from some old Civil Defense film strips. They're a nice graphical style, and as meaningless as Homeland Security. Been there, done that.

I converted my 1963 Rambler Classic (that's an automobile) to run on i propane (LPG) in 1989. Still driving it in 2005.

The still-useful chart of DB-25 and DB-9 serial pin-outs. This was the very first file I ever posted via http, in 1993 or 1992.

A wonderful list of "atomic"-themed films used to be at www.arts.usf.edu/art/nixnukes/nukemyth/film.html, but the site died; luckily I knew that would happen and saved a copy here.

Before all the security meltdowns at the Los Alamos lab, these images of "device" (nuclear bomb) tests was posted on wxvax7.esa.lanl.gov. Turns out that machine contained classified data! D'OH! Luckily I made a complete copy of these entirely public-domain images before the plug was pulled in 1999.
