I build one of those projects from BYTE in about 1984. A project for the
Commodore 64.
It was just two precision resistor networks connected through
CMOS drivers to the address lines of the C64. One network for
the lower 8 address lines and one for the upper 8. When the two
networks were connected to the XY inputs of a oscilloscope, you
had a 256 by 256 pixel display of where in memory the 6510
was executing.
I was making my living breaking the protection on disk software
at the time and this cartridge came in real handy for determining
where code was being loaded into memory.
I also started writing a TIC-TAC-TOE game for use with the
cartridge. The program would place JMP instructions in different
parts of memory to draw the TIC-TAC-TOE squares, Xs,and Os on
the oscilloscope. Sort of a vector graphic version. I had alot more time
on my hands back then.
