ROM-copy for 8052-BASIC computer

In an earlier article on our popular 8052-BASIC computer we showed a way to replace the 8052AH-BASIC microcontroller with the much cheaper 8032 or 80C32 and an external EPROM. This month we take a second look at unloading the BASIC interpreter from the 8052AH-BASIC and transferring it to an EPROM. We also avail ourselves of the opportunity to get to grips with serial communication protocols for the BASIC computer.
