C64 JiffyDOS question

Retroplay · 27 July 2011, 14:07

I have a JiffyDOS rom with an on/off switch which I haven't installed yet because I need to desolder the old 28 pin kernal rom first (C64c rev. 4 mobo).

Question is do I have to piggyback the old kernal rom if I want to run standard C64 DOS or is that included in JiffyDOS aswell (hence the switch) ?

Nevermind, no piggyback method needed.

You better post your question at lemon64.com or comp.sys.cbm. Kamel

No need to, I figured it out already.

Btw why didn't they use IC sockets in newer C64s.

Cheaper manufacturing costs and the fact that CBM didn't officially support hardware mods like this

And yet the SID chip is mounted on an IC socket.
