My first 8051 application was built using CP/M (Z80 machine) with only one 8 inch floppy drive and no harddisk. Assembling of 10 kb source took a few minutes. But I wrote a simple loader in TURBO PASCAL version 3 to download the executable file .TSK to the target.

Steve, I was born on 10th of october 1962. Yes, I must be very very old if I take into consideration the fact, that I'm programming ISDN PBX for almost 6 months, and I expect 2 or 3 more to come.
