| Oscar, When I arrived at DRI, my first project was to write a format program for the Harris CP/M-80 machine. It had 8" drives and needed to format all the combinations of density, heads, and tracks. My second project was to port Concurrent CP/M-86 v2.0 to the People machine. The project was three months behind schedule and I only had a matter of days to finish the port before we would default on the contract. The techniques I developed to accelerate the work were subsequently applied on my next dozen ports. Later on my techniques were brought into the main line code for Concurrent DOS 4.1 and later versions. The PEOPLE machine weighed about 50 pounds and was built like a tank. The BIOS was written in JAPAN, but commented in German. That was the first time I heard about a parallel schnitstelle.(bit-wise window) I went to the Olympia factory and signed off the PEOPLE port, and they took me to the executive lunch room, where I had a great dining experience and was offered a cigar. After the PEOPLE machine, I did the ACT Apricot Personal Computer port of Concurrent in the UK. After a brief visit to Monterrey, I was off to Japan where I used my kit to do the IBM 5550 (the Japanese IBM-PC). While there I did the first 80186 port of Concurrent on my Mad Computers machine. Those were the days. While flying around, I would read the airline magazine and see adds for machines I was just finishing up the software for. Those were glorious days for sure.
