Yeah its called the apple ][ ;-).

Does anyone know enough asm to allow backspaces on the board?

I tied the reset to the 8515 to the master reset switch (not the ground side ;-) ) so that the chip resets when the computer resets.

Seems to be working now.

...now that its built...what do I do with it :?:

Couldn't get the computer to work with a new chip.
Couldn't get the computer to work with a new ps/2 keyboard.

Every time I type a character that will cause a strobe to assert - I get a pulse out for 4 milliseconds. If I hold the key down it repeats every 50 milliseconds. When I type "L" no strobe occurs there are several other ascii compatible characters that don't cause a strobe to happen. When I type "2" ...

Different Keys produce other charachters like "return" would type "V" stuff like that. I think "1" is typed by pressing F6. I ohmed out the PS/2 connector to the 8515. The nets are correctly named as per the PS/2 spec but the traces go to the opposite pins. Schematic: KBD Data goes to pin 13 KBD Clo...

I'll just keep posting what I find as I debug the board. 1)Putting the 6821 back in did not solve the problem. 2)Examining the board with a microscope did not show any shorts - one joint looked bad but sufficient. 2)My 0-scope shows that the KBD CLOCK pin varies with what key I press and that KBD DA...

Not getting right characters PS/2 Keyboard

Assembly done today (same day I got the computer).

I'm not getting the right characters when I type on the PS/2 keyboard.

Not fun :-(

Has anyone else had this problem?

I've got the Serial Board Installed but not plugged into a computer.

Expansion

I would like to design an expansion card board for easily connecting boards to the replica 1. It would be able to connect boards to the replica that are single or double sided. It would carry three boards. This is going to be a good first project. Second Project: Flash card reader. Third project: Mo...

How many served?

Hey,

I find the replica 1 facinating and I would really like the computer to succeed. I was curious as to how many computers have actually been sold so far?
