Seeking 8-bit etherent card that will work with AT&T 6300

What brand\type of Ethernet card will work in AT&T 6300?

[Chuck(G)]

When I still had a 6300, I used an Artisoft AE-3 card. Worked fine.

Most should work fine, but I can verify the Intel Etherexpress 8/16 card does *not* work and never will. It has two modes of operation, port reads and memory window. It only supports memory window on 286+ systems, and the port reads are done via IN AX,DX, which is a word-sized read, and the hi/low bytes get swapped because of a flaw in the M24/6300 architecture. If you have the bus correction kit it will work, but if you don't, look elsewhere.

Chuck:

I looked up the Artisoft AE-3 and found only 16-bit. Did you recall if yours was a 16-bit card or 8-bit? Can a 16-bit card work in the 6300? If I did get this card, where would I find the driver's for it for DOS 6.22?

Trixter:

Would a 3-comm 16-bit work with AT&T?

[Trixter]

Only the 3c509b variant, if memory serves. An older 8-bit 3com is a safer bet, although since almost none of them have RJ45 jacks, you'll need one with an AUI interface and an AUI transceiver.

Don't know where you're getting your data, but here's the official datasheet. Note jumpers W5C and w5D that determine 8- or 16-bits. I like this card a lot because there's no setup program--it's all done with jumpers. If you're using UTP for connections, the Artisoft AE2/T is very similar.

I use a standard Novel NE2000 driver for it, which is available from a variety of places.

Sorry about the data mix up, I was looking at their picture of the Artisoft AE-3. I have reviewed the manual and 8-bit is supported through jumpers as was suggested. Thank you both for the information. While the Artisoft AE-3 or AE2/T cards are still out there. Their affordability comes into question. Also, the 3COMM 3c509b is affordable, however, the media converter for AUI and/or Thin or Thick net is not.

[Trixter]

AUI converters are around $15 on ebay, and if you set up a saved search you can find them for less from time to time. There are for sale/wanted areas on this forum. There are also vintage computer groups on facebook, email, and discord you could ask.

This card comes in many flavors. There is a 3c509b-Combo card that comes with AUI, BNC, and TP. There is a 3c509b-TP card that comes with AUI and TP. There is a 3c509b-TPO that is TP only. 3c509b-coax is AUI and BNC
