wow!!! This bring me a lot of memories. Back in 1988, I wrote a Forth program to control a X-Y table to control a ultrasound probe to inspect metal parts. The program was running on a Radio Shack Color Computer 2 (TRS-80) with 16k of RAM. The program itself was running in OS-9 operating system. Remember, there was no hard drive on this, only one floppy drive! Amazing to see how far we come from!
