Fixing my C128D

Oh and maybe I’ll fix this too whilst I’m at it.

I’m surprised it booted.

Is that the power connector?

I really hate unannounced hack jobs that you find when your ebay item arrives :(

That was the power switch, found a few other nastys too but got them fixed now and all the C128D bits transferred across and working.

Splendid :)

Just swapped the roms over between the two boards and the new board boots fine with the ones from the other, so at least I can rule that out now, same for the SID and VIC I & II Chips.

That's good, narrows things down a bit.

@rubber_jonnie the good thing is now that I've got a working C128D for Cyber Legends I can take my time and fix this other board up properly.

Yeah, that's great, will certainly take the pressure off.

Well done Phil. The show must go on eh? :D

[PhilC]

It certainly must @mrbombermillzy.

Not sure if it’ll end up being black by then but you never know.

Tried stereo SID in it and I’ll probably remove it as on some games it sounds worse not better.

EDIT:

So I remnoved the stereo SID board and had a bit of a play and decided on an R4 6581 for the C128D, it does sound a little more basie and has more of the pops and clicks that the SIDs are known for.

Right, must get back to fixing the other board!

Been doing a bit more work with the C128 board on and off. I’ve removed half of the 74 chips and replaced and socketed them. I’ll test the ones I replaced after I get this up and running.

I’ve got a new power switch ordered, one with all its pins present.

Next I’ll socket the rest of the chips including the ram after I give that a good test. Mind you, that’s only if it doesn’t boot with what I’ve done so far. So hurry up power switch!
