The following IBM PC and PC-compatible systems have been tested and found
to work with the LocalTalk PC Card and AppleShare PC. The actual working
configuration depends on what other cards are in the machine.
- Wyse 286
- Compaq 386, and portable PC
- IBM PC, XT, AT
- PS/2 Model 30
- AT&T 5300
Units that have problems are:
- The Compaq 286 running in 25-MHz mode. This can be changed to run at
8 MHz to work with the LocalTalk PC Card.
- The IBM PC 3270 is not an IBM PC and is not compatible with the LocalTalk
PC Card. It is essentially a 3270 workstation whose expanded
capabilities include PC operations. This system uses all of the DMA
lines and is not compatible with the LocalTalk PC Card.
- Any system that has a bus speed higher the 8 MHz. (Most do not provide
provide a speed-mode to switch to a slower speed, compatible with the
standard PC bus timing of 8 MHz.)
- Any system that uses all of the DMA lines.
- All pre-2.0 versions of ATALK.EXE do not support noninterrupt operation.
(Anyone running AppleShare PC or anyone who has purchased the LocalTalk PC
Card since mid-1988 will have version 2.0 or later, which DOES support
noninterrupt operation and will work in this situation.)
