Hello there :

	Can someone provide me some technical information about the
Adaptec AHA-1640 Microchannel SCSI adapter ?

The information I would like to obtain is :
- What processor/controller, if any, does this board use ?

- Does it have any on board RAM, if yes, how much ?

- Does this board use the parity bits on the Microchannel bus ?

- Does this board use the parity bit on the SCSI bus ?

- How many SCSI channel does it provide ?

- Am I correct that the transfer rate for this board is:
	MCA         SCSI async        SCSI sync
        8MB/s       5MB/s             2MB/s

- What is the average cost of the board.


Any help will be appreciated.

Ken
