This reply is a bit late, but I just received my digests this morning.... Although I have contributed some items, the Sol site is Jim Battle's - not mine. It is a wonderful resource for Processor Technology, the Sol, and also has some NorthStar materials. Jim's SolACE emulator is one of the best classic computer emulators I am familiar with. So if you haven't been there, I suggest a visit: http://www.thebattles.net/sol20/sol.html Bob Stek Saver of Lost Sols
