forth.hex: Modified version of Mike Riley's Rc/Forth, ROM version. Changed to work with my modified version of IDIOT. Loads in at 0500h. You can get it from the COSMAC ELF yahoo group.
idiot_new.hex: New version of IDIOT with SCRT routines, along with TYPE, MSG, READ, and INPUT routines for basic console I/O. Loads in at 0000h. You can get it from the COSMAC ELF yahoo group. For details see http://www.retrotechnology.com/memship/mship_idiot.html

C-H Ting, Juergen Pintaske and Steve Teal wrote the fine book FIG-Forth Manual: Documentation and Test in 1802 IP

Changed:

<
< I bought the book and the proposed Lattice FPGA board ICE40HX8K-B-EVN

(e.g. from mouser, about $50). This FPGA can be programmed as an CDP1802 system with RAM, UART, Timer and I/O, the serial console is also implemented as USB CDC!

?TERMINAL does not seem to work as expected.

Changed:

<
< The system on chip coded in VHDL and implemented for the Lattice iCE40-hx8k dev board is about 150 times faster than the Membership Card. That's about 300 MHz clock for an original CDP1802.
