[sdiy] hammond and pratt-read?

[Tom Wiltshire]

David,

Here's some photos of the 44-key keyboard I took out of a 1970's transistor hammond:

It has spaces for 3 sets of contacts, but only has one set fitted. The contacts have very fine pieces of some corrosion-proof wire on them. It's extremely well made and quite heavy. I wired it up as a diode matrix, although it wasn't originally.
