A JiffyDos from Retro Innovations.
I didn't want to make any hole in my C64's, but a couple of weeks ago I taked the "ugly" one to make all of the holes and "things" that you don't usually like to make. Well, you know... you want but you ... "shouldn't" if you understand me.
I've also ordered switches, leds, connectors and things like that.
I just think that this will be the C=64 that will give me more fun in return.
Edit: I've bought a switchless kernal switcher in Ebay... I don't like holes if I can avoid them.
Edit: I think that I commented here that I bought a C=128. Well... that was a BAD deal with my wife. It was a bargain and I couldn't let it pass, so I told her that it would be for my birthday. Puff, ahem ahem. Well... it will be in march and come on... the parcel unopened here, beside me
