Foenix F256 Jr goes online, OLD SCHOOL (CBBS meets a 5-line SuperBASIC RS-232 Terminal)
In this short video, we connect to *Ward Christensen's CBBS from 1978 (it's still running !!) using a 5-line SuperBASIC program and a simple serial connection using one of those new-fangled WiFi modems.
In early 1978, Ward Christensen (inventor of XModem) collaborated with Randy Seuss to create the first known instance of a Computer Bulletin Board System (BBS).
By the time a youngster in Patchogue, Long Island (me) got his hands on a VIC-1001 modem in 1983, BBS'es were absolutely everywhere, and many of them were so popular, kids my age would sit on redial tying up the home phone line for hours just to catch a glimpse of what treasures await (online games, people to converse with, and often, software downloads).
In this video, we briefly discuss the 1978 BYTE magazine article written by Christensen and Seuss, talk about the F256 Jr. Hardware, how to wire it up for serial communication, and then examine a SuperBASIC program to make it all happen. To close out the tour, we connect to a mirror of the original CBBS as it ran back in the day.
You will also see a refurbished Commodore C64 keyboard in use with this C256 Jr. In an upcoming video, we will go even further, and cook up a PETSCII based terminal, then connect to one of the many online resources for some character graphic fun.
Sad to say that Ward Christensen passed away on October 11th of this year (2024); aside from his contributions and passion for the early technology including CP/M, he worked for IBM for over 40 years. Another pioneer, gone.
Errata: I mentioned that my Father borrowed the Hayes Smartmodem (that is still in my possession) from work 30 years ago. That is incorrect, it was 40 years ago. Time flies!
*it's not really his online system but somebody is running a tribute site to honor the original.

A Tindie seller, peddling the WiFi modem I demonstrated; be sure to read all of the details and ask questions to make sure it is right for your before buying; but I can vouch for mine. It has always been trouble-free:

Link to the Foenix Marketplace, a website where you can download code samples and articles pertaining to Foenix computers and related 8-bit platforms. As of today, "Foenix Rising" is midway through its 3rd year since issue #1 was published. Each issue ranges in length between short-form (6 page development focused articles), and long-form, multi-article issues (of 32 pages). At this point, you'll find about 85% of the material is Foenix focused but you'll also find vintage references, and history pertaining to the works of Compute Publishing and Dr. Dobbs journal article discussion. I expect to be writing more Commodore related content in the next year; but even today, there are Apple II, ATARI, and even Rockwell AIM65 and KIM-1 references, with more to come: apps.emwhite.org/foenixmarketplace/

Lots to talk about in this one, and you may need to revisit... after many years, SIDlab brings a new set of capabilities for your single or dual SID equipped retro computer! SIDlab, now in beta 3, is being shown for the first time. This video is a bit rough, but you will hopefully get a good picture of where the software is heading. My disclaimer for today is the fact that I know absolutely not...

This 2nd video (of the 3-part survey on General MIDI) takes a 1/2 a step backwards to discuss MIDI, via the v1.0 specification. The video starts with a quick 5 minute tour of my “Keyboard Room”, to walk through a subset of important and historic synthesizers from the mid '70s to the mid 2020s, stopping at signposts for three examples of how MIDI functions as follows: Example 1: A generic MIDI k...

Between December 21st and December 24th of this year, I challenged myself to learn as much as I could from the aboriginal Christmas Demo in order to create something for the Foenix F256 that others could enjoy by the stroke of midnight.

This is the first of my monthly updates on the nanoEdit project. In early September, I produced a quick 'teaser' style video with no dialog or details; it was the first working prototype of Charles Brannon's SpeedScript editor from the C64 that I was able to get running on a Foenix platform. (look for this video if you've not seen where I started) Since that time, I've completely torn apart and...
