ZX81 peripheral supply PCB

For this project you will need :-

Some Veroboard

10uf 16v capacitor

7805 5v regulator

9v dc supply and connector for it ( mine is center positive )

some hook up wire

Here it is in use powering a ram pack for voltage testing!

It could be made a bit smaller and tidied up a bit. all 46 pins could be "broken out" to a header if a double sided version was drawn up in a cad package like EAGLE.

I might do this at a later stage! so come back and see if it is done!
