I use QNX4.22. I have old ethernet( Ethernet SMC 16 Combo ISA working with BNC coax), I would like to change these ethernet card (using PCI or ISA bus) but agree with QNX4.22 ( not QNX4.25) . Are there any ethernet card ( with BNC) ??
I find a AT-2400BT from allied telesyn ( but working with QNX4.25 !)
I think any of those old NE2000 compatibles that have a BNC interface will work.
