- I was not being cynical. I was merely hoping that it was not true.
- I apologise to Mr Townsend if I implied he was lying.

- Yes, but the ST also has a 16 bit processor. It is not crippled.
- The ST also does not have to deal with 16 bit graphics throughput.
- The Falcon on the other hand has a 32 bit '030, crammed into a 16 bit
- bus, similar to the Mac LCII. As for the Falcon not being crippled, I will
- wait to use the machine to see. I have my concerns about the speed of
- the graphics over a 16 bit bus, though. 16 bit graphics over a 16 bit
- bus, sharing access with the processor does not sound as though it will
- be particularly fast.

- And how do you intend to plug your 32 Ram expansion in?
- The PDS internal slot is 16/24 bit.
- The processor is surface mounted.
- Umm... not much else is there?
