First achievement with Bidule88: it is actually running some code that I've written and uploaded into its EEPROM! Here is the result:
The parts are connected as described on Homebrew8088 except that the EEPROM I used is bigger. Not that it is needed, though, the code is only a few bytes...
The 74hc373 on the left will latch the value written to any I/O port, it simply ignores the address.
What surprised me was how few loops I had to do for a 1 second delay between the counts. Clearly, that CPU isn't fast, and some instructions need a lot of cycles.
Next time we will start playing with a small LCD. Having some correct feedback will definitely ease debugging.
