TCP/IP for Econet

Postby philb » Sun Sep 10, 2017 8:11 am

Continuing my trawl through old disks, I uncovered the source code to an implementation of TCP/IP that I wrote for the BBC in about 1995. It speaks the same wire protocol as EconetA. In case anybody is interested I have put the source on github:

Back in the 1990s I converted the source code into BBC BASIC source here: http://mdfs.net/Apps/Networking/

It notes I found a couple of bugs, but I can't remember what they are.

Code: Select all

$ bbcbasic
PDP11 BBC BASIC IV Version 0.25

Oh, so you did. Good job there.

I have no doubt there are at least a couple of bugs in it. :D I should get it running again myself and see if I encounter any of those issues.

Ah, that takes me back.

Once upon a time, the house had Econet but no Ethernet. But we wanted to connect a Linux PC.

My solution: I hacked together a SLIP to IP-over-Econet bridge in a mixture of BBC Basic and Assembler then ran it on the host processor of a spare Z80 Acorn Business Computer. Happy days. (-8

Presumably, I still have that somewhere...
