Burning C64 ROMs ( part 1 ) : Kernel ROMs

I've always wanted to try to burn new EPROMS for my C64.  I remember as a kid pulling apart my carts and pretending I could mod all sorts of stuff into them.  Well now I can . . . sort of.

As part of my trouble shooting it looked like the Kernel/Basic ROM was shot so I thought I'd have a go at burning one.  Turns out it's actually pretty easy with the right equipment (It also turned out the Kernel ROM on the board was fine after all).

I bought myself a "TL866 II plus" and some 27128 EPROMS from Ebay.

This site has the C64 ROM images and which EPROMS are compatible:

The UV Erasable ROMs I got were actually ST27c128 which the software didn't have an entry for, but I read on the internet that if you just use the AMD AM27C128 and turn off the "Check ID" it works fine, and it does.
