They switched to a packet driver interface when the variety of Ethernet cards mushroomed. Anyway, I am sure some folks are curious to the system itself, so here are some pictures. Stated requirements are DOS 2. For this system to work you need to tell the packet driver what software interrupt it should claim. This page barely scratches the surface of DOS networking. Unfortunately the web pages for Trumpet are gone now. I hope at least this will work in XT.

An 8-bit Western Digital WD Ethernet card from is very different from a NE clone in a PC, yet c3509b packet drivers for each card make them look the same to the rest of the system. Pioneer SX, fully serviced! They switched to a packet driver interface when the variety of Ethernet cards mushroomed. Return to General Old Hardware.

I tried to load NE packet driver and ping. This isn’t the only silver-faced beauty I own, either.

3Com 3c – Wikipedia

Has anybody tested similar card? After the packet driver is installed, other software will 3x509b the packet driver by setting parameters and issuing the software interrupt. I checked out the Vogons’ driver data base, and came up empty handed for anything network related, but it was super nice for the GPU drivers! Where and how much should one pay for one. However, the 3cB will only work in a computer with a or higher processor.


Application software would use the API to send and receive packets. The growth ods DSL and cable modem devices in the early s made home networks almost a requirement, if only to allow sharing the one connection point to the Internet.

Other applications were written to use it too. Here’s a picture of the board with the VRM installed, outside of the case. Serial 3cc509b supported “hot plugging” removing and connecting devices while running while parallel ports did not, so swapping devices on a parallel port often required shutting the computer and the devices off.

Norton System Info reports this: Using a home network cuts down on your time “doing the floppy shuffle” and saves wear and tear on your system. I’ve been curious about Descent’s networking ability as well, between machines.

I was unable to find anything older than drivers, and thusly couldn’t verify if it was working in my 8-bit slots on my If people had any sort of connectivity it might have been to use a bulletin board 3cc509b BBS through a dial-up modem or to talk to a Novell Netware server running on their local network.

3Com 3c509

If that jumper is removed the card wouldn’t be generating IRQs at all. On the other hand, the rewards are well worth it. A full 3c509bb requires more memory than is usually available on an old PC. One of the great things about NCSA Telnet is that the source code is readily doe for download – with the correct build environment, you can modify it!


Often there was just one parallel port compared with two serial ports on a computer, and the parallel port was often connected to a printer. But the overhead of the parallel port does hurt performance, so while it is a good basic solution it will never beat the performance of an Ethernet adapter on a card.

I also changed IRQ to 5. Here are some places to look for a packet driver for a specific Ethernet device. There are lots of ways to doss computers together. Not sure on VRAM amount. The 3Com 3C based adapters are good choices.

They are not ne compatible. Back when DOS was a current operating system many machines were not network connected at all. Parallel ports also evolved to doz at faster and faster speeds using improved handshaking on the wires and even DMA. A packet driver makes the hardware and network accessible in an easy manner. Here are some examples:.
