[comp.sys.ibm.pc] PC cards work in new motherboard?

kahn@xanth.cs.odu.edu (Gary I Kahn) (01/03/89)

If I install an AT clone motherboard in my XT clone, what compatibility
problems can I expect with my current expansion boards?  The floppy
disk controller, for example, is currently running at the standard bus
speed of a 4.77MHz XT clone.  Will the controller, and the drives, work
at the higher AT bus speeds?  Also, will my Seagate ST238 and Adaptec RLL
controller work in the an AT clone?  Will my memory expansion board, with
its 150ns RAM, work on an AT bus?  I understand that 8-bit boards will
be limited to 8-bit use, but I want to know whether they'll work at all.
Thanks in advance.  If anyone is interested, I'll post a summary of
the answers that get e-mailed.
