  • Rocking the ROM

    Dave's Dev Lab • 08/01/2019 at 23:05 • 0 comments

    I got my 8-Bit ISA ROM Card assembled and tested! Of course I had to do a Hello World! program for a test! I've populated a Low Insertion Force (not Zero!) socket for easy insertion and removal of the EEPROM. I using a set of tools created by fellow hackday.io user SHAOS. He created some ROM tools for IBM PCjr, which I have created a separate hackaday.io project for. I was also able to write some code to test my 8-Bit ISA I/O Card as well!
