My CP/M (Version 1) Gets an Upgrade
My CP/M is a very small CP/M computerbased on the 8085 CPU.
While it worked, many programs over-wrote the serial I/O interrupt address (i.e. RST6.5) and the two 32kb FRAM disks were just too small to be useful.
So My CP/M Version 1A, swaps RST6.5 for RST7.5 (hopefully this works), and the FRAM chip capacity has been increased from 32kb to 256kb.
The available RAM is still 32kb.
