You are watching a set of two items:
One EPROM with the last OS for the Sequential Circuits Drumtraks (0.5) and a 32 pages booklet titled "MIDIGUIDE" with 3 extra pages titled "HOW TO UPDATE THE DRUMTRAKS SOFTWARE".
The booklet is a must for the basic and advanced Drumtraks users and refers to both versions 0.4 and 0.5 of the firmware. There is a lot of information like "Hidden Functions", "MIDI implementation", "MIDI key assignments", etc.
Contact if you need information.
I repair and collect synthesizers since 1992, I have more than 70 synths and I sell hundreds of parts for it. For the Drumtraks, I can provide you almost everything - Sounds' EPROMs, the RAM chips (MB8416-20), the DACs (Am6070 and AD7524), the TC4001 from Toshiba, NE5556, CEM3320, the potentiometers and even the double 7 segment displays (also in blue!!). I bought my Drumtraks without all the chips that could be removed from sockets and some malfunctions and had to source almost everything. I am sure that I can help you in any problem that you have.
My items are new and I send same or next day (depending on payment hours) in tracked mail with shipping costs included to anywhere in the world.
