A few more style tweaks, both to center the menu tabs, and to make things work better on IE6.
(My apologies to those using non-CSS browsers who are also not using IE6. The following is a public service announcement.)
Speaking of which, you should really upgrade from IE6 to something, anything, more modern. IE6 was released in 2001 and hasn't been maintained in years. Besides getting a worse user experience, you are exposing yourself to numerous, known security risks.
Please, download the latest version of Internet Explorer and install it. It will replace IE6 on your system and you will be much better off.

A number of style changes, but no new content. In particular, the main font size has been reduced a bit, the menu system was reworked, and the bar at the top was restyled.

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 Senzig, 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.
- 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 ...
