Keyrah and Amiga 1000

[Zac67]

I think so - the reset works differently on the A1000 but the rest is exactly the same.

[Zac67]

On later models the reset signal (from three finger salute) is generated by the keyboard controller and there's a dedicated pin to run it to the system board.

The A1000 keyboard encodes it through a very long signal on KCLK and the actual _RST has to be regenerated by U4M (LM2901).

Since you probably don't need that function, it shouldn't really matter. ;-)

Oh, wait! Keyrah is only for passive keyboards like the A600/1200 ones, isn't it? So this won't work with the A1k KB.

[Zac67]

Possibly the A1k KB uses the same matrix as later models, so it might work with removing the controller and connecting the then passive matrix to a Keyrah.

However, there's been a controller change from A1000/A2000A to A500/A2000B (my A2000A keyboard hangs in some games), so there's a chance the matrix was changed as well. You'd have to compare the keyboards to find out.
