One ROM usage in vintage synths and drum machines

[perbal]

Hello all,

A large number of vintage synthesizers and drum machines - several hundred, in fact - used EPROMs to store firmware and/or sound samples. If you look at the well-known DBWBP website, you’ll find more than 1,200 EPROM dumps from vintage synthesizers.

For example, the Sequential Circuits DrumTraks from 1984 is powered by a Z80 microprocessor and uses 2764 EPROMs to store and run its firmware, as well as to store drum sounds.

Can One ROM be used in such devices to both store and run firmware and/or store digital sounds?

Thank you!

generally speaking yes, it certainly can.

vintage synths and drum machines are really just vintage computers with really nice sound cards and bad user interfaces.

Yes, a 2764 is really not going to cause One ROM any issues. I'd recommend you think about space around the ROM - whether you want an inline USB-C connector or upright one.

For 2764 you need a 28 pin One ROM. upright USB-C connector versions of those are available from me and others - and of course you can have your own made.
