Details ... I want to know that ISA. :)

Nope Just the X brand of FPGA's. I use the A-brand of FPGA's because at
the time the 10K10 was the only chip that looked BIG in a low cost FPGA
kit. ( 2 years ago ). They don't have 16 bit dual port memory like X.
I may do a CPU design with PLD's rather than one large FPGA as they have
two advantages 1) They can be programed externaly and stay that way 2)
they are about the right submodule size --- uart , floppy disk, bit
slice for playing around with custom logic.
