Considered by many as the best 8-bit computer ever made, the 128 and 128D actually contained two processors. The 2MHz 8502 (which ran Commodore 64 software) and the 4MHz Zilog Z-80 CPU that was completely capable of running CP/M 3.0 software such as Turbo Pascal and WordStar. By this time in the market, the Macintosh and Amiga computers were far more powerful and could do more but it was surprising to many how much could be accomplished with the right software. The only difference with the 128D over the 128 is the packaging of the computer and the inclusion of the 1571 drive right in the main chassy. There is a separate entry for the Commodore 128.

 

This computer is currently interactive in the Museum.

I still have my 128D, and it works perfectly. I used it mainly for music and games, and a little programming. Those were the good old days, dialing up to Q-Link every night.

I didn't know it then but I was in-between high school and college at the time and working in Kitchener, ON for Chubby's Pizza which was owned by two friends of mine. They wanted to replace the old cash register (it had a crank handle in case the power went out.) I recommended a computerized system. Since I had so much experience with Commodore I recommeded a C128 for the job. I programmed in all my spare time and created a cash register system that was custom built for pizza. It included a payroll system, a customer database and lots of other features. It grew so large that I had to purchase a BASIC compiler to work around the memory constraints. I even built an auto-dialer for it. It would generate the specific tones needed to dial the phone. We could hold the phone up to the monitor speaker and select a customer record to dial. I really got into hacking on that C128. It was my first experience with machine language programming. It was needed to do an animated splash screen for the cash register program.
