Hey all, happy to announce that NODE Vol 02 is out featuring 180 pages of articles and interviews about P2P and open hardware projects, with an updated Open Source Directory and new Meshnet Atlas! Download a digital version for free or preorder a hard copy https://n-o-d-e.net/zine/index.html
Happy Friday the 13th! Wednesday is celebrating appropriately. #cats #mastocats
I got 2/3 of my Gandalf short haul #modems working! Now I can theoretically do RS232 over miles of two-pair. Still want to fix the third modem but that might be tricky. #modempunk
If you have a TTY/TTD device and want to give it a try, I have one set on auto-answer mode at 484.996.1337. Feel free to leave a message!
Here is a photo of me connecting to it via a baudot-compatible modem.

NIST still offers a dial-up service that will give you the current time.

The lab's still a mess in case anyone was wondering.
Updated http://dialup.world with info for what I'm doing! I'm sure I'm doing something incorrectly but it all sort of works.

Tonight I ported @neauoire@merveilles.town 's Uxn VM to the MegaGRRL hardware (my ESP32-powered VGM player). Seemed like it would be fun, and it was :)
Here is a little demo...
Had to lower the screen resolution (not enough RAM for full screen framebuffers!), but it has sound, output through the YM2612's DAC register. D-pad emulates a mouse. Also had to do a bodge to the drum-rack example to get it working on the lower resolution.
Third modem in the pool! I don't think I need three modems for the ISP, maybe I'll dedicate one to fax later.
Don't know how I had so many missing/incorrect words in the last toot, but I think it still makes enough sense.
Previous thread on the project is here, https://mastodon.sdf.org/@Famicoman/106502130156592758
An update to my dial-up ISP project. I got a two node modem pool working a PCI card to add more serial ports. Instead of my Verizon line, I patched these modems into my PBX running asterisk with a Grandstream ATA with 4 internal lines. The PBX takes incoming calls from a new voip.ms number and uses a basic hunt group to connect to caller to the next free line.
Got a dialup modem? Feel free to give a call and let me know what OS you are using, how it goes. Details at http://dialup.world
Had this for years, never any idea what it was. Decided to open it and turns out it is a 40 meg SCSI drive. I have a friend with SCSI gear that should be able to image it, so I'll add that to the to-do list.
If you spend a few days playing with modems it feels natural that you eventually create a dialup ISP.

@Famicoman reminds me of the time I turned a TRS-80 Model 100 into a serial terminal.
