- Using Forth to Transfer Data from Vintage Machines
- This presentation with describe methods of transferring data from vintage
computer systems that have unique non-compatible disk formats. In particular,

USART-encoded floppy disk and transferred to a PC over a serial interface.
Forth was employed on the PC side and assembly language on the H89.

in June 2003.
Immersive Systems Inc. offers it

Metatopia Project
Meme is written in plain-vanilla C, so it ports to any machine with an

"The source to Meme and Metatopia comes from three donors. Mitch
Bradley of Firmworks (http://www.firmworks.com) donated the interpreter on
which Meme is based. Marc de Groot of Immersive Systems, Inc.
(http://www.immersive.com) worked on Meme for 20,000 hours to bring it to its
current state. Master Zap (http://www.master-zap.com) implemented Metatopia, as
well as a number of demos featured on the website..."
