You are watching the EPROMs for using Linndrum sounds (erroneously known as Linn LM-2) in Sequential Circuits Drumtraks:

one 2732 EPROM with the bass/kick sound of the Linndrum
one 2764 EPROM with the snare sound of the Linndrum and the original Drumtraks RIM sound (actually the RIM sound is the same in both Linndrum and Drumtraks).
one 2764 EPROM with the Hi-Hat sound of the Linndrum
one 2764 EPROM with the claps and the tambourine sound of the Linndrum.

The crash and ride sounds are the same in Linndrum and Drumtraks and the cowbell and cabasa too. The tom is really close. If you need, just ask and I will send you the sound samples in .wav format. All the EPROMs are new and the quartz window is covered by a UV proof sticker. Check my other items, I still have a small lot of low profile zero insertion force sockets. Changing sound with it is a breeze...

You can buy it individually or as a set to save some money.

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.
