Greg–I have a LUCAS/FRANCES board that I've been trying to get running. I
recently installed the 1.3 ROM upgrade published in amazing computing
(which involves removing the daughterboard and installing a ROM socket. I
cheated by using back to back sockets and not removing the daughterboaRD
connector pins, so the mod is reverible and I can add Rejuvenator at a
future time. Antyway the new PAL chips are faster than the old setup. I
have gotten LUCAS/FRANCES working fairly well at 12 MHz, but am having
compatibility problems with LUCAS/FRANCES and my XETEC HD and Ramboard. I
suspect the faster PALs are altering the syste timing just enough to throw
off the HD and ramboard. They sometimes work at 12 M but the system won't
boot at faster clock speeds. Anyway I mention this to you in case it helps
with your debugging of rejuvenator and because you mentioned to me at
AmiExpo that a new capacitor might be needed to improve LUCAS/ HD
compatibility with rejuvenator. I assume we'd be talking about a cap to
delay AS slightly. Anything further on that? Good luck.
