Quote from: Bryce on Today at 10:41If the jumper wire is lying across the PCB and (as is the case here), the user doesn't have a scope to confirm the clock signal, then they have no way of knowing if their test is running as expected or not and the results can't be trusted.
Quote from: McArti0 on Today at 10:32Quote from: Bryce on Today at 10:25Just out of interest. Have you actually tried to do this setup in reality and confirmed it works? Or is this all based on theory?I did exactly that yesterday. Everything I write in this thread is tested (on real CPC16128)Quote from: Bryce on Today at 10:25The reason I ask, is that connecting anything at all directly to a crystal pin will usually dis-balance the capacitance enough so thatAnd that's how it should work. GA is supposed to permanently turn off the clock and thereby freeze itself in a specific state.
the clock will either not start at all or will be unstable.

Quote from: McArti0 on Yesterday at 23:56How to test 74LS373 without desoldering.Just out of interest. Have you actually tried to do this setup in reality and confirmed it works? Or is this all based on theory?
The pictures show the procedure for stopping CPC on a single read from the internal RAM memory. at the end we have the state of open 74LS373. RAMRD and READY are low.
ORG #0638
LD HL,#B100
LD DE,#B101
LD BC,#07F9
LD (HL),A
.L0642
LDIR <----- here we are stoping CPC
By setting the data pins of the internal bus, you can check whether these states pass to the external bus side. RAM pin 14 set to Lo (grounded) should show the same on pin 2.
If you are surprised by the polarization of diodes, know that I am surprised too.
