Hi,
An exciting change of priorities leaves me with many items looking for
new homes :-)
On offer here are the two PCBs, pre-programmed PIC and three EPROMs
(i.e. all the "custom" parts) for building Trevor Page's TR9090 drum
machine. This was one of the first TR909 clones and, I believe,
replicates the circuitry faithfully but omits the sequencer. Most of the
other parts are standard unless you are particularly finicky about the
VCA, in which case there are a couple of specific transistors to hunt down.
I thought it was a brilliant idea to build one of these and then
conspicuously failed to do so. All I managed to achieve was to fit and
beautifully solder the 100K resistors - you can do better than that!
I have all the latest documentation available to pass on.
Asking GBP50 plus postage at cost to wherever you are. Payment by bank
transfer or Wise preferred - can also take PayPal but with a surcharge
to cover their ridiculous fees.
If you really want a head start then I think I also have some of the
bulk components (TL072s, transistors) required - please ask.
Thanks for looking. Happy to answer any questions. More to come!
Cheers,
Steve L.
