Bought a new PAL 800XL from B &C Computervisions

Being in the US I doubt the difference between PAL B and I will bother you but quite a lot of the new flatscreen TVs sold in Europe tend to support the common PAL formats, out of the box.

You can alwayse find the commonly available TTL logic ICs that the non-freddy XLs use for these circuits.

 

There's one exception, and that's the delay line part. Fortunately, I don't think they're easy to kill. Freddie uses a ~14MHz clock and doesn't need a delay line to make sub-cycle RAS and CAS transitions.

You could even build the delay line out of analog components if you had to.. The MIo uses a similar design for it's on-board PHI2 generation when the atari is off.. Its just 2 chokes and 3 caps..

Looking at the 1064 schematics, it appears to just run /RAS through LS04 invertors 4 times in order to get a delay.
