replica 1 and apple 1 3 slot expansion board

Here is a photo of the prototype slot expander 1 board. It is compatible with both the replica 1 and apple 1 boards.

Slot Expander 1

I have more tests to run but it is working great. As long as all the tests work out production run will start in November. Estimated price is $59 assembled or kits for $49.

Maybe add a card edge connect

Maybe add a card edge connector to the left hand side so you can have more boards? Smile

Yeah but that would increase

Yeah but that would increase the price to have those added by about $15 for gold fingered edge. Besides, 3 should be plenty. Oh man, didn't Bill Gates eat words saying something like that.

It's not the fingers, but get

It's not the fingers, but getting them in gold for a slot connection. The apple 1 side is soldered directly so they don't have to be gold but to daisy-chain multiple boards you would want gold contacts for the fingered edge of the board. This adds about $10 a board depending on how many you get.

The Apple-1 would be fine wit

The Apple-1 would be fine with tinned fingers. My whole altair still works 30 years later and it has plenty of tinned fingers. : )
