Drawmer M500

Version: 1.79

An oddball compresor that used two Z80 cpus to control VCAs. Didn't sound any good at all.
Had it in my hands a million years ago, so don't remember anything more about their internals,
as well as unlikely there were any photos from the insides (if I made any, those could only be on film...).

However, since I found those dumps in my old archives, maybe these can be useful to resurrect a box or two.

Chips: 27C256 and 27C128A

Serial number is hard coded in master rom at ~@$7FE4, but, if I remember correctly, there is no checksum, so you can freely change it.
