Well, Lee, Adrian and Mark - how about this?

DesTestKernal - a version of DesTest that you can program onto an appropriate PROM as a replacement for the C64 kernal ROM. When cartridges fail you, this little beauty might just get the job done!

Yesterday I was goaded by @morefunmakingit.bsky.social and @adriansdigitalbasement.com (with @theretrochannel.bsky.social as a likely accomplice).

Now what do I do?

At Heathrow central station waiting for a bus to take me to Swindon for RetroFest this weekend.

A few more and you'll be able to build a C64 completely from failed chips. That's got to be worth something to someone.

This is very cool. Glad to see it!

I bought myself some of the SuperPLA sockets recently with the intention of fully socketing my shortboard. I have found neither the time nor the testicular fortitude to do so. I think perhaps I've been inspired.

I venerate my '128.

Can has SCART too?

I'm glad to see you've put your new Swiftlink to such a great use!

The addresses all being the same turns out to be a bug that @morefunmakingit.bsky.social has expertly discovered in some new (not yet released) code. (now fixed).
The quickest way to find problems with code is simply to let other people try it.

Well now I'm wondering that too...

The border and address ($D800) indicate something went wrong testing video SRAM nybbles.
What is not clear is why the same address shows up so many times (the maximum should be 4 times per address).
Also, the colour RAM looks fine (well, black text is correct).

That monitor has some fine looking stickers!
