Scott -- this is the low-end ("good") system specification:

ISA buss; VESA local-buss if no extra cost; FLASH BIOS (?)

386DX/33 or 40 (the AMD version) with 64K cache if possible

8mb RAM (eventually to be expanded in 4mb increments to 16mb)

2 serial connectors; 2 I/O (bidirectional) parallel connectors; 
PS/2-type mouseport optional

Local-buss 1024x768x8, x16- or x24bit color display system,
or superior (e. g., Hercules Graphite) ISA buss card 
(to be used with MultiSync or comparable monitor)

120-200mb IDE HDD - use Stacker 3.0 to expand this

1.2mb & 1.44mb FDDs

best quality keyboard, small-tower or desktop case
