Hi Ewan !

I recently bought a Percuter in a package-deal and got a bunch of cartridges for it too. Including a Boomer-cart.

It is nothing I plan on keeping and was actually off to my workshop today to pick it up prior to putting it up for auction locally in Sweden. What a coincidence !

I can sell you the Boomer cart and one other if you want to for you to reverse-engineer.

Let me pick them up and get back to you with some pictures.

sorry to speak about non Simmons electronic drums! but i suspect that some of you electronic drum nerds here might be able to help me (there dosen't seem to be a group for dynacord drums anywhere on the net)

i recently got a Dynacord Percuter that doesn't have any sound cartridges.
being an electronics nerd, i have decided to make my own cartridges.

i have found the service manual for the percuter and they seem simple enough to make, but it would make my life much easier to have high res fotos of the pcbs inside the cartridge. since the cartridges are not covered by the service manual

there are several different cartridges, a 32k factory cart, a 64k factory cart and an eprom cart(from the boomer) the most interesting one is the boomer cart, because it has switches to set decay length, and filter frequency. but fotos of any would be enough to build a replica.

i might be interested in buying a working or non working cartridge if somebody has one for sale at a reasonable price.

thanks, and sorry for the offtopic post.
