Here are some files that might be useful to somebody but which aren't worth building a whole web page for.
A former Wang engineer, Max Blomme, had the foresight to hold on to a service manual containing a ton of schematics for various Wang hardware designs. I scanned them all in 2003, and some of them have made it online in my Wang 1200 and Wang 2200 websites.
His manual had schematics for some Wang calculators as well. I don't have any pressing interest in them, but I scanned them all anyway. Here they are.
A Kaypro 10 that I was given had a number of source files in one of the user directories. A quick web search indicated they weren't already on the web. I snarfed them for posterity and present them here. On boot the screen reads:
* KAYPRO 10 v 1.9E *
Then it prints a version string and settles into the command prompt.
KAYPRO 10 CP/M Version 2.2F
Each file was dumped twice and compared for integrity. Your browser might think these are some type of quicktime file because of the suffix, but they are plain old ascii. If you can't view them in your browser, save them and open them in your favorite editor.

Here are five years of the North Star Horizon Compass newsletter, published by INSUA. Each year is a separate pdf file; each is about 4-5 MB, containing only image scans; no OCR.
For a short while I had an Interact Model One Computer, acquired off Ebay. It was a later version of the Interact Home Computer System. The Model One had been repackaged for easier assembly and more reliable operation, but otherwise appears to be electrically identical to the non-Model One version.
Sadly, the computer got somewhat damaged in transit, but it still worked. I couldn't find schematics online, but I was helped out by Joe Britt, who kindly sent along the following scan of the schematic. He said it was OK to post it, and so here it is for your benefit.
While I was poking around in the machine, I dumped the ROM (a masked ROM, EA 8316E093, date code 7836F, I believe the label says). This ROM has the same pinout as a single voltage 2716 EPROM. If yours gets corrupted, the 2716 will replace it nicely.
A few years ago I traded a working Sol-20 computer and an OSI 4P for a working Exidy Sorcerer. I had always wanted one since I was a young teen, reading the ads in Byte Magazine. Due to a lack of software and time, I eventually sold it off, but not until after I scanned a few docs that came with it that weren't online (that I could find, anyway).
My Sorcerer came with a demo tape. The Sorcerer uses the CUTS format, which first appeared on the Sol-20 computer. Martin Ward has written a program which can analyze a .wav recording of a CUTS tape and produce binary files with the contents of each logical file on tape. If that doesn't work for you, you can also try this one written by Ed (no last name given).
If you are successful in recovering the files, any BASIC program can be
this quick and dirty perl program
that I wrote for the job. If you've named the binary file produced by Martin
program.txt, you can produce a listing like this:
exidy_detokenize.pl program.txt | more
Because it was very common to embed user definable characters directly into
The first few lines of each listing contain information about the file header,
and aren't part of the program proper.
Here is a zip file containing the eight BASIC programs which appeared on the demo tape, both in binary form and as readable ASCII listings.
Bob Senzig sent along this vintage computer store catalog (72 pages, 1.7 MB), in memory of his brother, Don Senzig, Jr., of Milwaukee, Wisconsin. It is full of 1977 goodness.
