Here are some files that might be useful to somebody but which aren't worth building a whole web page for.
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:Then it prints a version string and settles into the command prompt.* KAYPRO 10 v 1.9E *KAYPRO 10 CP/M Version 2.2FEach 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.
I recently (early 2008) acquired an Interact Model One Computer off Ebay. This is a later version of the Interact Home Computer System. Although it has been repackaged for easier assembly and more reliable operation, it appears to be electrically identical.Sadly, the computer got somewhat damaged in transit, but it still works. 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.
InteractSchem.pdf (six 11"x17" pages, 3.5 MB)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.interact_boot_rom.hexIf you have any other documents from the Interact computers, please send them along.
If you want to contact me for whatever reason, try me at frustum@pacbell.net.
