I would get the 50Mhz PGA if you have a Blizzard 1230-IV, I'm not sure if 33MHz will work properly (or at least efficiently) with a 50Mhz '030.
There's also space on the SX32/Pro for a PGA FPU.
Dumb terminals often have NAND Eeprom drives of 256MB or less which, when ripped out, can be plugged into the A1200 IDE interface to give you a super-fast solid-state disk!
:-)
Be careful when removing the PGA ones at least - the pins are extremely fragile.
EDIT:
Slightly off-topic but has anyone ever seen a plug-in clock for the A1200's clockport on eBay or somewhere?
