I remember those alpha days ,,@exxos, are you sure it was just the ports?

It is good to see an actual PCB, good luck with getting it all up and running.

Has there been any more progress on this ? Would be cool to attend another Cyber Legends event, as last year's was cool :) CiH and I are possibly considering renting a table, so do please let us know details on this. The location at Leighton Buzzard does look good too. Yes Leighton Buzzard does loo...

The CPUs we tried with the TF536 did work okay, so you should be fine at 25mhz

I’ve ordered some caps and will try the other board in a few days.

rubber_jonnie its the deflection coils plug that’s the main difference, the spare board has an offset pin but this one doesn’t. Then of course I haven’t got and radial 2200uf or 470uf caps to complete the recap. I’m going to see if I can find a new HT coil for it. Something a bit like this. IMG_307...

Is it from the same machine or something different?

Same machine but the analog board must be a different revision.

And of course I’ve spoke too soon, the HT has now started to make that distinct high pitched whine that it does. Fortunately I have a spare analogue board, so let’s hope the pinout is the same.

So a bit of news, In between being unwell (ongoing unfortunately but no sympathy needed :lol:). Ive been working on and off with a few things, so the Mac C classic has had a bit of attention over the last week. The good news is that after changing the Misfit, Opto Coupler, Switch mode cPSU chip, all...
