Keyboard beeper

Post by Lardo Boffin » Mon Mar 19, 2018 1:46 pm

Hi all

I recently bought some ZX81 stuff as there was a set of assembly instructions included. As well as a 2K RAM expansion in a cassette case! :D

Clearly the previous owner was into electronics as there were a few snippings from electronics magazines.

One of them is this - a keyboard bleeper. Doubltess already posted but here you go.

In case anyone is curious here is the 2k RAM pack. The wires to the edge connector go through the case! :shock:

No - the paperwork etc. only arrived today. Plus all my retro stuff is in storage for a while. :cry:
