[sdiy] TR909 clone PCB pictures

[Trevor Page]

Hi again,

For those who are interested, I've uploaded some jpegs of one of the two
TR909 boards that has been completed. Sorry for the crappiness of the
images. My ancient camera together with my dodgy photography skills make for
rather undazzling results.

Looking at the first image, from left to right, EPROMed hihat and cymbal
circuits occupy roughly 1/2 of the board. Then the rimshot and hanclap
circuits, then and the hitom circuit. The MIDI interface can be seen along
the bottom. The second board will contain the remaining toms, snare and
bassdrum and power supply.

I'll get some html up there sometime with more info, but in the meantime
feel free to email me if there's anything you'd like to know.

Cheers,

Trevor.
