Computer Interests

edit
  • The PL/I programming language. I have been a PL/I enthusiast since 1967. I am an evangelist for the language, and also work to retrieve old PL/I software and documentation to make it accessible on the web. I manage "The PL/I Language", a website devoted to PL/I. I have a large collection of PL/I books and materials, and hope eventually to write a history of the language.
  • Software Archaeology. I would like to spend more time with the revived Multics Operating System and IBM TSS. I am trying to help with the revival of the XDS CP-V operating system.
  • OS/2. I started using OS/2 2.0 at introduction. I have been an OS/2 supporter and member of Team-OS/2. I moved to eCS and then to ArcaOS.
  • Since retirement in 2010 I have written a PL/I compiler, and founded and run Iron Spring Software. I hope to promote use of PL/I and maybe eventually make some money.
  • I have been a contributor to Wikipedia since 2008, mostly minor changes to articles in my areas of interest, and occasional articles on subjects where I have some knowledge and Wikipedia has no information.

122 Regent St., Saratoga Springs NY

Previously, I enjoyed taking (not-very-good) photos of local Saratoga Springs and Troy, New York historical sites, some of which I uploaded to Wikipedia. If anyone wants to take a better photo, you won't hurt my feelings if you replace mine.
