Great! Please let me know if it all works - I think it might be a different version of JiffyDos for NTSC and Pal, but I could be wrong (has been quite a few years since I installed Jiffy in a Vic).

If it all works please message me - interested in an assembled unit for the Vic 20 (do not require IC hooks etc as I handle a bit of soldering and the unit will be permanent).

Thanks!
