I don't know, old PC's are a dime a dozen. Still TTL buffers is all you
really
need for I/O if you don't mind wasting the high order byte.
OK, I actuially have a US dime somwhere. Please tell me where I can
exchange it for 12 PCs capable of running FPGA or CPLD development software.

PS. They also sell 8051 products for the 'real' programmer. :)
