    ARCNET users: What does your setup look like?

    Somebody asked me about ARCNET performance problems with mTCP, and I went down the rabbit hole. They are using the ARCETHER packet driver as mTCP is only designed for Ethernet. With smaller packet sizes it works fine but the performance is bad. With larger packet sizes and buffers it runs...

    Public Service Announcement: Beware of scammers, they work here too ...

    Suggestions for hand tools that are helpful when working with vintage machines?

    A friend introduced me to the Wiha Chip Lifter, which is basically a small prybar that seems to allow more control when removing chips from sockets. I've also discovered the dental picks are useful for scraping corrosion and manipulating flexible copper contacts in tight locations. Are there...

    Rules/Guidelines for the Off Topic area

    We have an off-topic area for discussion of newer machines and tech that are not vintage. There is also a quite a bit of very off-topic chatter, and we acknowledge and allow it because this is a community. However, I've had to just outright delete a few threads that have "gone off the rails."...

    Docs wanted: Motorola Universal Data Systems 212A/D

    I came across this today and rescued it: However, documentation seems to be very hard to find. I have found some manuals for earlier modems from the same company, but not anything for this modem. By chance there was a paper note inside of the cover that gave me the magic sequence to get into...

    News: Sale of .org registrar to a private equity firm

    And this is not good news ... basically, the group that handles registering .org domain names has been sold to a private equity group. It is certain that prices will rise because private equity groups exist to make a profit, not serve the public interest. Here is a petition backed by nten.org...

    Importing old messages

    Shawn provided me with a Zip file of the Yahoo! group that somebody scraped. The messages are in "email" format, so they look like full emails with all of the headers. vBulletin has an API for creating threads. Writing some code to import each message and add it to a new thread (or an...
