Using this used to help in testing the program on a Battery backed up Ram. The final program could be burnt on the Eprom which was erased in UV Box and could be rewritten probably 50 times only. Hence testing and debugging in the RAM is much easier. You could use Software Test Points to tell the PC the status of each stage of the program. This helps in debugging or building software block by block.
8051 Single Board Computer - This is a Kit you can use to learn the 8051 family.
This is a 8051 Operating System ;-) . In an old elektor
issue, around 1990 perhaps, i got a 8031 circuit and monitor
code by Grodzik. This helped me interface a 8051 to PC via
RS232-serial-comm port with HyperTerminal. Now you can use Termite
- a simple RS232 terminal to transfer and receive
bits-n-bytes to the outside world.
