Cromemco 8K Bytesaver EPROM board. Working. My dad and I each built one of these. I think this one was mine.
Here is the .PRN file from a simple program I loaded into a 2708 to test my ability to program an EPROM with Martin Eberhard’s post era ME2700 Orphan EPROM Programmer. On my Imsai front panel I examined the address C000 then pressed run. Yup the programmed output LEDs change state based on the programmed input paddle switches.
Now it's off to find a simple monitor program to load in EPROM(s) and decide which I/O card to use for serial communications.
; jha 2/10/2016 !Light data LED for corresponding switch
; ImsaiTp1.asm Imsai Test Program 1 from pp. 35. of Imsai documentation.
START:
C000 org 0c000h
LOOP:
C000 DBFF in 0FFh
C002 D3FF out 0FFh
C004 C300C0 jmp LOOP
C007 end
