Re: Running a beeb with no keyboard plugged in

I don't think they worked when i got the machine no, i've had a flick through the acorn service manual and I suspect ic20 74ls139n might be iffy as its linked to all the rom sockets and s20 s21 and s22 links, s12 ans s13 have no pins to link so are naturally open. Is there a way to test ic76? Apart ...

Ahh, the VTI VC2023 has a design fault, boards fitted with this chip should have a wire modification (normally hidden under the board on the bottom). Search the forum for "VC2023" for more details...

Re: Running a beeb with no keyboard plugged in

Err 8V??? Do you mean 5V or is it actually 8V? Must have had the meter on ac, just rechecked its 4.18v on boot then .19v after the *fx132,12 The resistance of IC76 pin 3 to IC1 (6502 CPU) pin 33 should be less than 20 ohms, as it is the D0 data bus line that you are measuring. And the power should ...
