I have recently acquired a R65F11 IC. This IC is part of the RSC (Rockwell Single Computer) Forth system.
Rockwell Single-Chip RSC-FORTH system as implemented in the Rockwell R65F11 (40-pin) and R65F12 (64-pin) FORTH-based one-chip Microcomputers and in the Rockwell R65FR1 FORTH ROM (which I do not ahve, but the ROM dump is available on the RSC Forth page.
