I think it would be about time that there was a dedicated section for old 8/16 bit programming.

Great idea!

I agree and it will be done. Sorry about the lack of forum admin recently from my side but I'm snowed under with real life coding work :( - Don't worry though as soon as I've hit the last key on the backlog coding shite I'll leap into action and be uber Qube once again :P
Until the next time...

Excellent.   :D

Look what arrived today, the LumaFix64 (it improves C64 image quality).

While my tv picture is much better than this example, here's a review of what it does for image quality:  http://biosrhythm.com/?p=1340

Decided to get the C64 up and running properly today. Stuck it into Vic 20 mode and got tinkering. Surprising all the old manual poke addresses I still remembered such as 36879 to change the colours.

Yes the emulators really cover all the bases, so are great for testing...I just wish they could offer smooth scrolling though.

Here's another find on the net that maybe worth a look at for the C64.

Cool.  We really need to put this info into the new 8-bit page.

This guy seems to know his C64, Commodore 64 Assembly Language Programming of particular interest here.

Well I've been gradually increasing the amount of time I leave the old C64 on for.  A few days ago I came back to the computer to see 'Mayhem in Monsterland' exhibiting some worrying screen corruption in the top third of the screen (dark lines at first).  As I watched the scrolling it got worse as the top section of the scrolling background began to tear back n forth.  At this point I turned the computer off.  I tried it the next day and those dark lines within the top third are still present.

I know that replacing the capacitors can improve picture quality, but I'd hoped that I wouldn't have to do any repairs for a little while.  I don't yet even have a soldering iron so am not equiped to make any running repairs.  I'd seen C64's listed as 're-capped' but they cost more than I was willing to pay, because I knew I wanted to also buy a modern replacement power supply and floppy disk emulator drive (and those things weren't cheap).

So basically it's man down for now until I can get at least a soldering iron and new capacitors.  I don't have any spare cash at the moment so that will have to wait, a shame.   :(

When it's running, do the finger test on the IC's. If they are hot, then there is a chip failing.

Thanks, I'll try that when I'm in a position to do some proper maintenance.

So I guess it's back to the emulator for now...

Well we're all in lockdown and guess what?  The TV goes.  So I bring the TV that the C64 is using downstairs...And that quickly goes completely nuts.

So no TV what-so-ever!...On the (possible) plus side the trouble with the C64 picture could well have been a TV rather than computer problem.

You meanwhile could try to stream the video streams of your beloved TV channels - most of them offer "live feeds". If uncomfortable, then install Kodi on a connected laptop / box and run some ipTV addons.
