I'm new here. I have a number of old Sun Microsoft servers that I restored back to life. The latest is a Sun SPARCserver 670MP that I restored from two machines. It has three 5 1/4 inch hard drives that sound like a turbine engine when they spool up. The UNIX OS version is SunOS rel5.5.1 (Solaris 2.5.1). My favorite is my Sun Ultra Enterprise 450 SPARC server - has 20 hard drives of 36G each. Runs UNIX Solaris 10 as well as Windows running inside UNIX on a SunPCi3 card. This 300 lb beast that keeps my office warm in the winter. Other Sun machines are Sunfire V440, SPARC T-5 server, SPARCclassic lunchbox computer, and Sunfire X2100. I found two IBM (Power 720 & P615) servers and quickly found out why they were inexpensive - you have to buy the OS from IBM. They make good sea anchors! The WANG Professional Computer has got to be the heaviest PC built with the largest PCBs. Other PCs I've collected are ones I purchased new like the IBM PC and Compq 850. Still others I found are Commodore 64, TRS80 model 1, Morrow PC, Franklin PC, lots of Apples, Kim-1, SYM-1 and Rockwell-65. But the latest one that fascinates me is the Altos 8000 CP/M machine with a real nice TeleVideo 910 CRT. I want program in Z80 Assembly Language, but it has become more of a challenge than I thought. I put a thread about this in the CP/M & MP/M topic. --- Thanks!
