- This is BS. If you have ANY fast ram (which will be 32bit ram) the 28.8 WILL

- Unlike the PC machines, the Amiga handles the serial MUCH better and MUCH
- faster. The bottle neck is not really the CPU but rather interupts. As the
- amiga internal serial port will create an interupt for EVERY byte sent, this
- is a problem. So the CPU has something to do with it, but not everything.

- Again, if you have any 32bit ram you should be fine.

- I have an A3000/030 with 14 megs of ram and a GVP I/O Extender. Now at one
- time I had a two line BBS. I own a V.Everthing USR 33.6 modem and a ZyXEL,
- which can connect at 19.2.
-
- I had both modems on the GVP and hooked up a null modem cable. I was
- recieving fido mail at 33.6, had a user on the ZyXEL and was sending files to
- my Amiga from the PC at 9600. My machine DID it. It was a bit slow but it
- did work. The user on the board did not notice ANY slow down.
