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.

Third modem in the pool! I don't think I need three modems for the ISP, maybe I'll dedicate one to fax later.

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.

After watching the recent LGR video, I knew that I had a few Cybikos kicking around and decided to transfer over a terminal emulator and connect to a Raspberry Pi. Surprisingly the Cybiko Console software works on Windows 10 and gives you a boot log, some basic commands, and the ability to file transfer. Next step will be battery replacement and figuring out why some of these just don't work. And if anyone knows how to do an OS upgrade these days let me know.

Can you tell I'm working through my mail pile? Wanted to test this new programmer I ordered.

The RetroSpy Game Boy Printer support works perfectly. Game Boy thinks that it is using an actual printer!

My first time soldering a SMD. Time for a break.

Installed two RCA jacks on the #pxl2000 for audio and composite video. Reassembled things and it works great with composite video from the new jack. The battery terminals are fairly trashed, but I wasn't planning on using this on-the-go anyway.

Added the underclock and link port mods to the Super Game Boy. Apparently the SGB runs faster than the actual GB which causes issues with the bitrate on the link port. So far nothing explodes when I turn it on, but it won't interface with the Game Boy Printer. Need more troubleshooting.

This will get a much longer writeup but I've been fixing up a broken PXL-2000 that records video to cassette tape. RF output didn't work so I performed a composite video mod. Then the lens assembly was wonky so I modified that. Soon I'll add some RCA connectors and clean heads.
