I want to know if there is a PCMCIA LAN card that don't conflict with the accelerator card
PCMCIA don't conflict with Blizzard 1240-T. New Blizzard turbos have their memory in 32-bit area, so there is no problem in this respect.
You can use most NE2000 compatible cards with cnet.device. To see a list of the compatible cards, check
cnetdevice.lha for the compatibility list.
You can also use some 3com compatible cards with
hard/drivr/3c589.lha.
