Can recommend the following:
Accelerator:
Phase 5/ DCE Blizzard 1230 MKVI or 1240 or 1260. These are great classic accelerators and just work.
It just depends if you want a classic setup? What do you plan to use the A1200 for?
If not classic setup. Then for a CD;
The Sony VAIO PCMCIA CD drive
If staying classic;
Archos PCMCIA 2x or 4x CD Drive.
