C-FLEA Developers Kit


Super Developers Kit (All of the above + extra assemblers and tools from XASM)


*68HC08 and 68HC16 Developers Kits do not include a monitor/debugger.


A complete C virtual machine development and runtime environment


C-FLEA is a "virtual machine", which was designed from the "ground up" to run 'C'. Provides an easy way to implement 'C' on CPU's that are not supported with standard 'C' compilers, are too small/weird for efficient native implementation of C, or use a system design requiring memory that is not directly executable (eg: serial). The C-FLEA can also be used to implement 'C' application languages embedded within other programs, and has many other useful purposes.


This package is licensed for single use. Low cost runtime licensing is available should you wish to re-distribute the VM interpreter.



A PC based 8051/52 and Dallas 80C320 Simulator / Emulator


A software simulator/emulator for the Intel 8051/8052 series of microcontrollers. EMILY features an easy to use "windowed" user interface, and is capable of simulating at better than 500,000 instructions per second on a 486/33mhz PC.




A set of cross assemblers and disassemblers




These are "smart" disassemblers with many features to assist in the generation of complete symbolic/commented ASM source from binary machine code.





Powerful software debugger and monitor programs.


Monitors for 6809, 68HC11, 8051/52, 8080/85, 8086 and 8096. Includes XASM compatible, well documented source code.



* Some features may differ slightly in some monitors



Data Line Monitor. Turns your P.C. into a DATASCOPE


This program monitors both sides of an asynchronous data communications line using a passive "Y" cable which connects to the monitored devices and BOTH comm ports (COM1 and COM2). This tool is invaluable for debugging ANY asynchronous connection, such as TERMINALS, MODEMS, SERIAL PRINTERS and PROTOCOL debugging. It allows you to actually SEE the data and signals being passed between the devices.
