My IBM 1410 FPGA project now features a working 1401 mode as well, with
the flip of a switch, exactly like the original IBM 1410.
There are still a few real problems (e.g., Console I/O Input under
program control doesn't seem to be working), a few minor issues
involving console problems when d
Over the past couple of months I have been working on my FPGA
implementation of the IBM 1410 1960's era pre System/360 system again.
I am pleased to share that the CPU now passes a significant diagnostic,
CU01, which tests almost all of the instructions, and also tests I/O
with overlap and the
