John, Sounds like fun! I'd like to see a bit more comprehensive listing - each category may not need to be filled in for every computer, but if you start by defining a comprehensive list at the outset, at least all the entries will end up consistent. I'd like to see a list comprehensive enough that I can take it to a garage sale and know how I can use the box I find there. Also, remember that as time moves on, more and more capable machines will become "classic". My NeXT will be right in there in 4 more years or so.... :-) Things I'd like to add to the list in any case: Output device/resolution CPU type/speed Mass Storage (floppies, tapes, hard drives) Operating System(s) Things that may or may not belong on the list: Important Available Software (word proc, telecom, spreadsheet, etc.) Known Current Vendors/supporters Benchmark speed (a la Byte Magazine's Seive Benchmark) Neat things to be able to do with the list (or database): Sort by OS Sort by CPU Sort by date available Sort by Manufacturer Sort by Model Name A sample (not necessarily complete or correct) listing for my classic: Name/Model Rainbow 100A/B/+ Manufacturer Digital Equipment Corporation Date released/stopped 1983(?)-1986(?) CPU Z-80/4 MHz + 8088/4.8 (?) MHz RAM/ROM included 128k/32k(?) (RAM up to 832k (100A) or 896k (100B)) Output Device VR-201 (mono) or VR-241 (color) monitor; avail. graphics to 792 x 240 x 8 bits (?) Ports included 2*RS-232 (printer, modem); video/keyboard Mass Storage 2 or 4 * 400k 5.25" floppy; avail. MFM Hard Disk < 80M Peripherals offerred LA-50, LA-100 Printers Modem (any RS-232) ...
