Cells are Forth Computers
CH Ting
*"Cells are computers. Code are stored in DNA, like disk drives. Code are transcribed to RNA, like RAM, edited, and then released to perform functions. Some RNA release microRNA, which cause transcription of RNA. MicroRNA are instruction set of the cell computer. Many RNA contain lists of microRNA, which are Forth high level code in cell computers."

Forth on the Gigatron TTL Computer
Ken Boak
*Ken will describe the Gigatron TTL Computer - an 8-bit machine built entirely from TTL, that is an unusual candidate for the Forth language.

Forth-Based Radio Direction Finder
Andrew Korsak
*Andy will describe his work-in-progress remote Radio Direction Finder reporting network.  He is using Gforth on a Raspberry Pi and substantial progress has been made. 

Making "Standard Tapes" Using F-PC Forth
Jay McKnight, Magnetic Reference Lab, San Jose, CA 
Using analog magnetic tapes for audio program interchange requires standardizing the tape flux. This can be done by standard physics lab methods, but most audio engineers have neither the equipment nor the knowledge to do it. So we record and sell "Standard Tapes" to carry this information. We use an oscillator, a tape recorder, and a control system   made with F-PC to turn the tape recorder on and off, to announce the tones, and to control the frequency, level, and duration of the tones to be recorded. As is usual in Forth, the final word is the program. I will describe a few of the zillions of words that we need to do this."

A Tale of Two Forths
Joseph O'Connor
*Joe will discusses both the JavaScript and Python implementations of Creole Forth. 
Joe actually built the first version of Creole Forth in 1999 and presented it to the Maryland Forth Interest Group. In 2003 he cleaned it up and presented it to SVFIG for the first time. There are now four versions (1) Delphi/Lazarus component (2) Excel (3) JavaScript (4) Python. Joe will concentrate on the JavaScript and Python versions although you may see something of the other two Forths in passing.

The Gerund Programming Language, a Joy-like language for Dictation
Have a look at the web page ... http://wiki.yak.net/1133  (may be squeezed in after lunch)

Squeezing Forth into 64 Bits
Brad Nelson
*"Over the last decade 64-bit processors have largely displaced 32-bit, outside of embedded applications. Recently, operating systems have begun dropping  support for running 32-bit processes on 64-bit systems."
     "A larger natural cell size, enough to fit whole Forth word strings into a single machine word, is an opportunity to simplify the design of Forth. I'll explore what this looks like in a small Forth, and touch on how OS hosted Forths fit into a world of ever growing complexity."

Forth Robot Invasion
Don Golding
*If you've followed the saga of Don's robot boards on the email list, you know all about it.  If not, you'd better subscribe and catch up.  Boards!  Bring money!



1. GreenArrays Status Update - 15 mins
2. Daniel Kalny's presentation - 53 mins plus Q&A
3. Recent work at GreenArrays - Remaining time till Chuck.
Daniel's title and abstract:
"Can you speak USB-ish?"  Low-speed USB host implemented in GA144
With the aim to plug a USB keyboard into GreenArrays' evaluation board we have implemented a simple USB host in GA144 chip. We'll show the overall HW and SW design, key parts of code, and demonstrate functionality of the keyboard controller with Chuck Moore's etherForth display and a new etherForth editor.


     We try to stick to the schedule, in particular on Forth Day.  Remember that schedule slip is sometimes unavoidable. If a guy's on a roll, one wouldn't want to interrupt.

      Once in a while we shuffle things around, for whatever reason.  It may be ill-considered, but it isn't malicious.

      If you're desperate to see a particular thing at a particular time please mention it and we'll try to accommodate you.  If we get enough of this sort of request,  we'll institute a system of graft and corruption in order to accomodate the well-healed among you. 


     The schedule above may be reformatted or line-justified but please transmit it verbatim and in its entirety or not at all.  A link to this page is preferred.

     No Newsgroup posts or other media distribution please!  Contact me and we'll discuss it BEFORE you proceed. 

Coming Attractions: 

     Dwight, when his hardware is working!
     Future Thoughts:  --- Chuck Moore at EuroForth 2018
We'll turn off the YouTube stream and watch ... YouTube

Euroforth 2018 was held on the outskirts of Edinburgh - at a venue in sight of the
>famous Forth Bridges (now 3 of them!). As this year is recognised as the
>50th Anniversary of Forth, Charles Moore was invited as Guest of Honour.
> Chuck gave an after dinner speech - which has been captured on YouTube by
> Jaanus Poial.
