Program : RISM and IECM51.EXE compatible host system
Description : RISM is a reduced instruction set monitor and
IECM51.EXE is its compatible host system for a PC
Comments : These two programs together constitute a bare-bones
method of developing 80C51 system code without an
emulator. RISM51X is installed in the target system
and connected to a host PC system through a serial port.
The host PC runs the debugger IECM51.EXE. Once the
system has been debugged, RISM can be removed and the
target can be run in stand-alone mode.

Description : - Signature-Scheduled dataflow operating system
(RTOS) developed for embedded single-processor and
distributed microcontroller systems. Easy to use,
very compact, and encourages totally deterministic
and safe performance.

Intel has announced that 8052AH-BASIC has reached its EOL (end of life) and is not any more in production. Resellers may still have some chips in stock. However, both source and object code is available in many ftp-sites (and Intel BBS) and can be loaded into any 8052-compatible internal ROM memory (or external ROM, but then PROG and DMA cannot be used).
At least few years ago, MicroMint Inc. (4 Park St, Vernon, CT 06066, USA) was selling their own 80C52-BASIC at USD 25, speed DC 12 MHz, CMOS.
