Free Stuff - November 2022
The November recipient for the Great Scott Gadgets Free Stuff Program is Alex of the CCCSBG Hackerspace. A group of people at the CCCSBG Hackerspace are making an effort to explore the protocol spoken between ancient IBM3270 terminal equipment and their controller. Alex points out that Andrew Kay has done similar work for text-only traffic [1], but mentions that his hackerspace wants to chip away at the graphics capabilities of the IBM 3270. We have sent Alex and CCCSBG a GreatFET One so they can sniff the traffic that is going through the NS DP8340 and NS DP8341 chips on...

December Update: Merry Christmas and Happy New PineTab
Merry Christmas, happy holidays and a Happy New Year to you all. This month’s update has a different formula from the usual - aside from the announcement of the PineTab2, most of this month’s content is dedicated to looking back at this year and taking a sneak peak at what’s to come in 2023. I think that if you read between the lines, even poorly, you’ll get a good idea of what we’ll be up to next year.
RetroNetCall: "ISDN B-Channel protocols"
I've presented about ISDN B-Channel protocols (X.75, V.120, V.110, T.70, ...) as part of the RetroNetCall talk series on retro-networking technology.
You can find the video recording at https://media.ccc.de/v/retronetcall-20221207-laforge-isdn-b-channel-protocols
Many people with some kind of telecom background are familiar with D-channel (signalling) protocols of ISDN, and you can find many publications on that topic. Surprisingly, much less publications are talking about the B-channel protocols used for data transmission, like VX.75, V.110, V.120, T.70, ...

Updated Delivery Date
Note: This is a crosspost of a Cynthion update on Crowd Supply: https://www.crowdsupply.com/great-scott-gadgets/luna/updates/new-delivery-date
With almost every project, delays tend to happen. LUNA is no different. In good news, we have received all of the components needed for LUNA. In not-so-good news, we have not been as lucky in gathering components for the other products at Great Scott Gadgets. Over the last couple of months, we’ve had to move our head hardware designer (Michael Ossmann) from the LUNA project and onto redesigning some of our other hardware so Great Scott Gadgets can continue to exist through this chip shortage. The result is...
New MAC Address Range
We are happy to announce that Onion Corporation has a new MAC address block. Onion devices can now have MAC addresses in the range of 88:1E:59:00:00:00 – 88:1E:59:FF:FF:FF, with 88:1E:59 being the new OUI (Organizationally Unique Identifier).
What is a MAC Address?A MAC address, or Media Access Control address, is a unique identifier assigned to network interfaces for communications within a network network segment. Every Omega2 device is allocated three sequential MAC address during production, one for each of the available network interfaces:

Free Stuff - October 2022
The October recipient for the Great Scott Gadgets Free Stuff Program is M0nkeyDrag0n! M0nkeyDrag0n has requested a GreatFET One in order to explore a potential bug he found in Windows. We love supporting researchers and look forward to hearing about what M0nkeyDrag0n finds.
