I wasn't quite sure which forum to post this in, a programming/hardware project on a bit of 6502 nostalgia.

That is just sick. I like it.

I'm surprised the VIC-20 has the cycles to do that. I'm impressed!

Given that the ping reply is 10ms or so it could probably support being pinged from 70 locations at once (standard DOS 32 byte ping) without using up all the cpu time.

As it only supports one TCP connection at any time web pages appear slow due to multiple simutaneous requests from the browser mostly being ignored and so waiting the retry timeout. I have some plans to improve this by stacking a few half open connects.

Lots to do on the code yet, TCP is mostly a kludge and needs the error packet handling cleaning up.

You know what would be absolutely sweet is if you could get this thing to talk also to a Commodore 1541 disk drive. The software could be a Citadel-family BBS (these kinds of BBSes are awfully small and compact, and with their circular message stores, require virtually no maintenance from the sysop). Maybe support some 8 to 16 people online at a given time. Just make sure you remember to knock inactive people offline, otherwise, denial of service can be easily achieved. I'm thinking something they could telnet to.

Done an update, the TCP/IP code now handles up to eight threads at once. There's also a page on the Vic PSU as mine errrrr .. anyhow you can fix them. 8^)=
