Just to discover that code in this ram couldn't run, because the
Z80 was too slow. Only useable for data.
Huh? An opcode fetch takes the same amount of time as a data fetch. The
opcode fetch also has a bit of extra time in the cycle (4 clocks vs 3)
to squeeze in a DRAM refresh (damn near everyone recognized this ability
when designing memory controllers; stalling the MCUs accesses just
to steal a bus cycle would be a significant hit on bandwidth).
clair voyance test system, and the program (assembler) fitted in
1 K Ram and the testresults were stored in the 16 (maybe 32 ram).
The idea was that you couldn't discriminate clair voyance for
paranormal communication, unless the result were checked by
a computer and not shown to any one.
I bought a DEC writer (5 by 7) for 2000 guilders to print theYes, increasing levels of integration have taken a lot of the
test results, and use a black and white television for the
monitor. Those were the days.
[There we no indications for paranormal happening.
The circuit to generate random targets was hardware and
pretty solid.]
