        Does ex-Port really work?  How slow would it be to use a 8-

bit parallel port into a 16-bit 8Mhz bus.  I don't know, but it must 
be really slow, I would not put anything that requires a lot of use 
on that bus.  I have a IBM PS/2 Model 70-A21.  I would use a TransFormer 
2 for your purpose because it has to be faster that a parallel port. 
It is made by Advanced Digital Corporation.  Description:  Converts 
the MCA bus to PC XT computer bus so you can use PC XT computer interface 
card with PS/2.  This cost more that $1000 though.  I'm going to call 
CCSI and look into this product you brought up.  It would be great, 
but I know the parallel port is slow! for a computer bus, lots of 
wait states.
