Craig message reminded me of a CGA emulation program that allows auto- booting programs to work under emulation mode. The program came with the hercules clone graphics card that came with my system. The name is COLOR. From the replies I've received, it seems that my best shot is to see how COLOR handles the rebooting and whether I can do the same to slow down the computer. If results are positive, I'll post a message and if there is a demand, I'll post the specifics.
