hi mike/all, 
i�m looking for something to read/study on memory registers, eproms, etc. 
can you recommend/link anything? i want to make a start. 
 
reason being, i�ve been messing around with synthedit, the modular synthesis 
program, and have learnt a fair bit about the voltage control/logic control side 
of things, in terms of routing signals, etc. and think i�m ready to start thinking 
about programming memory locations/patterns etc. 
 
at some point, i�ll �up� my findings, re: randomizers and resets and stuff, as 
it�s all reasonably interesting, informative and meticulously laid-out, so maybe 
being useful, to synth bods in general, without wishing to be a smartass newb.
any help from anyone, most appreciated. 
cheers all, 
dom
