Moved to a new web hosting service. Please let me know if you notice any missing links or other hiccups. One side effect of this move is that a few .pl files refuse to present as text/plain mime type despite the proper .htaccess file configuration, so now I expose them as zip files.

Don Sensig, Jr., of Milwaukee, Wis. was an avid participant in the microcomputer revolution. Sadly, he passed away a few years ago. His brother, Bob, sent me some of Don's things, which I've digitized and put online.
- Tad Enterprises tape -- convert PT BASIC to run under CP/M. Recovered from tape.
- Microchess, by Peter Jennings. This was recovered from tape.
- Bob sent a tape containing, among other things, the source code for the CUTER monitor. I wasn't able to cleanly recover it all from tape, but I did compare the boot parts to the listings I already had online. These older listings were generated by cleaning up the output from OCR'ing a printed listing. By diffing the two, I spotted a number number of errors, almost entirely in the commentary text. The updated cuter.orig and cuter.asm are now online.
- It isn't specifically about the Sol-20, so I am hosting it on another website, but there is a good chunk of a 1977 itty bitty machine co., inc. catalog containing PT goods.
I also took the opportunity to scan a few magazine ads and articles which I've been meaning to get around to. All are available from the Newsletters, Articles, Ads page.
Finally, I updated the links page for a very interesting utility that I used to recover the tapes Bob Senzig sent. Martin Ward wrote a KCS/CUTS decoder in Perl (of all things), and uses a sophisticated FFT approach to discriminating the 0s from 1s. It is slow and takes some fiddling sometimes to get the parameters right, but it works pretty well.

I added three manuals that I've had for a a couple years but never got around to scanning. All of them can be found on the Manuals page.
- ALS-8 Firmware Module Assembly Instructions
- CUTS, Computer Users Tape System, Assembly and Test Instructions
- Extended Disk BASIC User's Manual
... anything over a year old is no longer noted ...
