BCI51 The first (and still the only?) real-time BASIC compiler for the 8051 family. Blazing fast integer math. True real time interrupts. Easy support for in line assembly code. Most of the power of C at a fraction of the price. Much faster development than using 100% assembly code. Easy customization of I/O for your hardware. Runs in a DOS window.
	Free RAD51 (standard) The new standard in freeware 8051 assemblers, and a true Windows product. Integrated Development Environment and 8051 Assembler for Windows 95/98/NT. It works well and it's FREE.
	RAD51-390 The first firmware development tool to support the Dallas DS80C390 Dual CAN high speed controller 22-bit flat address mode. Imagine 4 MBytes of address space in an 8051 with no paging or segmentation!
	BASIC-52 Products BASIC-52 is well-suited for quick development. It's not capable of real-time interrupts, and because it's interpreted, it's slow. It's a low cost, simple way to get started with embedded control systems.
