EDIT ~
I've just discovered that my monitor cable is faulty as the screen went blue and flickered when jiggling it about, i've just swapped it for another cable and the screen is rock solid again

Once I get the PAL decoded I can hopefully shed some light on what's going wrong!
I usually find that a big hammer helps at this point.
Dave will that be with a GAL in it or PAL? How much?daveejhitchins wrote: ↑Mon Jun 25, 2018 7:41 amI could also test them before sending - Or i could just send you a working Turbo board . . . ?

Always a bit random from days to months. Sometimes even from the same supplier.
Cargo ships take ages. Any luck it will be air mail. We send boxes via Cargo ship can take anything from 1 month to 3 months. (When they arrive)CMcDougall wrote: ↑Fri Jun 29, 2018 12:02 pm^ depends on when the cargo ship sails, so if they catch day before bonus
The would be a GAL.

Has anyone got their old pal they can send me to replace my lost one otherwise this board is useless to me without one.

Well, as there are at least two versions of the Slogger Click PCB, and at least two versions of the Slogger Pegasus PCB, it's entirely possible...
