I crafted a script that could relocate my borland C++ exe into a file that could be loaded into an EPROM.
Fantastic! Loved using the V25.

Very first game I bought for my newly created rig – Sierra Online’s Hero’s Quest, later renamed So You Want to be a Hero. Kept getting artifacts on the screen with the game. Did some reading, discovered my CPU was too slow. Did some research, found my solution in a Jameco catalog I got from tech school. Filled out the order form, and 2 weeks later, my upgrade arrived. WOW I WAS AMAZED at the huge speed boost. It wasn’t “a bit” or “a little”, it was a very large noticeable difference. I later sold that system (because I upgraded to an 80386-16 computer) to the head of security at work. The next day he commented “You’re right that computer’s fast, it’s almost as fast as a ‘286!”. Those were the days.
