I have been planning to build a computer from about 1973, with Star Trek
as my only computer model. Finally 50 years later I have one that works.
Most of it finished now because of low cost PCB's off the internet.
Getting a working mother board is harder than it looks.
I totally forgot about the on-chip register file! Thanks for correcting
me.
Thinks, I still need more blinking lights on the front panel.
Star Trek's computer displays always had interesting patterns.

After reading the ALGOL 60 paper, why did I go 18 bits, I could have had
27 bits or a V8. :) I have 9 bit alu bit slices.
The Electrologica X1, had the upper block of core memory as ROM for
fixed system programs use. I am doing the same for my computer.
Did any other computers have the same concept before the 1977?
