I'd be my old faithful 1986 Apple //c, with it's optional disk drive and its green 9" monitor. Or perhaps an SGI indigo2 MaximumImpact R10000.
update : corrected, Yes it really is a 9 inches monitor, not a 9 feet monitor :)
Comment on Re: Would kind of computer would you be?
Old thread, but the //c would be me as well - foshure. Only three programs would be needed - Ultima IV, the edasm macro assembler and the Beagle Bros Bag of Tricks :)
