Steve, Thanks for the link, I did actually read and use this info while working. If I have significant updates or learn something new that others may benefit from, I will post here.

No tempo changes are required as the C64 and P500 have the same clock speed. I also managed to convert the C64's "Master Composer" player to run on the B-series... almost. I'm sure it wouldn't take too much to get it to work on the P500. > > What is also interesting about the P500 is that an entire bank of 64K memory can be dedicated to the VIC-II chip. > > If you're looking for more P500 info check my CBM-II page... http://email@example.com/CBM/index.html > > I have some new info on the B-series HP internal drives, and I just managed to aquire a board I mentioned - an adapter board that plugs onto the SFD-1001 motherboard and adds the second drive, basically making it into an 8250LP. Unfortunately the board is not working, but the guy I got it from has a working unit so hopefully it can be fixed. > > Steve Gray > > PS: My first post to cbm-hackers... although I've been reading for quite a while. > > > > ----- Original Message ---- > >> From: B Degnan <firstname.lastname@example.org> >> To: email@example.com >> Sent: Saturday, July 11, 2009 10:01:16 PM >> Subject: P500 Conversion from PAL to NTSC >> >> I was able to convert my PAL P500 to NTSC using the directions found here: >> http://landover.no-ip.com/pet/forum/index.php?topic=196.0 and parts from a >> broken C64. >> >> Here is the boot screen: >> http://vintagecomputer.net/commodore/p500/thm_P500_NTSC_bootscreen.JPG >> >> I have also been able to write simple music programs using the SID chip, which >> appears to use the same memory location as the B Series, not the C64.
