I have build my own programmer. This device can program the AT89C51 and works with it. So it can easily be adapted to programming other devices by itself.
The Atmel Flash devices are ideal for developing, since they can be reprogrammed easy, often and fast. You need only 1 or 2 devices in low cost plastic case for developing. In contrast you need 10 or more high cost windowed devices if you must develop with EPROM devices (e.g. Phillips 87C751).

graspForth is my humble attempt at a Forth-in-C that has the following goals:
GCC ......... to support all 32-bit micros that GCC cross-compiles to.
Relocatable . to be able to run in-place in either Flash or Ram.
Fast ........ to be "not much" slower than an assembly based native Forth.
Small ....... to fit-in approx 300 words in less than 25Kbytes on a 32-bit machine.
Portable .... to achieve a 5 minute port to a new 32bit micro-processor, or micro-controller.
