So, some status updates:
VCF East was a success, with an approximate turn-out of about 50 people in the room, watching the presentation. Video was recorded, and is forthcoming from the VCF people.
I have been asked to speak at VCF West, the first weekend in August at the Computer History Museum in Mountain View, CA. I will be on after the talk given by Brian Dear (the author of The Friendly Orange Glow, the book about PLATO and its history who literally inspired me to DO THIS in the first place.) It will be a nice book-ended pair of talks, with Brian talking about the past, and me talking about the present and future of PLATO especially in the context of the vintage computing community that would benefit most from it.
I also have been asked to speak at VCF Midwest in Chicago in September.
I have been hosting meets weekly, the next pair of meets will be:
Saturday, June 2nd, 10am-12pm CDT
Sunday, June 3rd, 10am-12pm CDT
Meet links on the site in my signature.

I set up a booth at Classic Game Fest 2018 in Austin, Texas, to show off Irata Online on an 800XL. It was running The Learning Phone cartridge and was connected to the internet over Wifi, via the Raspberry Pi in the Lego case. There was a fair amount of interest and a whole lot of nostalgia, both for the Atari and for the PLATO service.

You're welcome. It all works out. I enjoyed it and if I had not done this, I probably would not have gone to CGF at all. And that would have meant missing out on an awesome weekend.
I saw a lot of 2600s and 5200s, and even a couple of Jaguars and a table-style Pong, but I only saw one other Atari 8-bit computer. Unfortunately, it was being sold for parts. So as far as I know, I had the only working Atari 8-bit computer in the whole place. I'm also pretty sure it was the only online 8-bit of any type.

I was able to connect successfully on a real Atari thanks to Thom and Steve's conversation on PLATO.
First thing was to change my flow control setting on my tcpser command line (from "&K0" to "&K1"). And second was to use the SHIFT-SUB key instead of SHIFT-STOP at the "group" signon screen.
So amending my instructions from earlier:
1. ssh to the raspberry pi
2. On the pi, I run: tcpser -s 1200 -d /dev/ttyUSB0 -i "&K1" -n5555555=cyberserv.org:8005
3. On the Atari, disconnect any disk drives and ensure the 850 is connected and powered on.
4. On the Atari, boot "The Learning Phone" cartridge. If the R: handler is successfully downloaded from the 850, you should see "1200 baud" message, otherwise it might say "Microbit 300 baud".
6. On the Atari, I need to press <OPTION>+0 (zero) to disable local echo (otherwise double-characters appear).
7. On the Atari, I enter atdt5555555 and press return. (This phone number is registered to the cyber1 server in the tcpser command).
8. A reply from the PLATO service appears: "Press NEXT to begin". Press <START>+n.
9. At the clock screen, enter username and press <START>+n.
10. At the group screen, enter group and press <START>+<shift>+<=>

I'm curious. Would this method work with a Lotharek SIO2PC/USB instead of using a Serial-to-USB cable?
Similar to this method, which describes how to use SIO2PC/USB for serial connection: http://atariage.com/...s/#entry3450741
Atari > 850 > SIO2PC/USB > Pi
Or will it only work using the Port 1 on the 850?
Any help would be appreciated. Thanks!

If you get a capital letter or a lower case letter with an ascender underneath a letter with a descender they already touch -- with both the orginal font and the one I designed. You can see it happen with "space" and "objects" in the first paragraph, and with "help" and "things" in the lower-right info text section (in the Empire/History text that I used for a sample).
It's not the bottom and top line that you're seeing in each character, it's the bottom line of each character you're seeing. The bottom line of one character becomes the top line of another character and so on, which gives you the idea that there are two blank lines. And, as I pointed out above, this line is not always blank (for descenders). So, things are already quite tight for line spacing.
I'm basing my 220 on Altirra and my own CRT monitor. I did make a thread in order to get some samples of what most people's current monitor setups will allow them to see. But I only got about a handful of useful responses.
[Edit] Also, as stated previously, 220 still doesn't give the full 32 lines of text needed to support the current terminal configuration; and I'm not sure there's much that can be done to get around that -- aside from allowing text off screen to be scrolled to.
The last line is almost always blank or empty on any plato screen I remember.. it didn't scroll in my mind it just wraps to the top.. It would be safe to discard the last line or make it pop up or be 'peeked at' like the current options bar in the new platoterm being made. I really think your method would be rather cool to be seen.
