[sdiy] Midiverb reverse engineer project?

[Paul Schreiber]

MANY years ago, I reversed a MidiVerb to maybe 90% of the schematic.

As I recall, it was a standard Mealy-Moore state machine all done in TTL.
The EPROMs held had both 'microcode' and the reverb coefficients.

It ran fairly fast, like a 25MHz 'instruction cycle'. I don't remember it
having any calls/jumps, it was pretty much 'straight line' execution.

It would be a piece of cake to reverse one today, just saying. The whole
thing would fit in a $2 ARM part.
