Hi Hokie, sorry for the delay in getting back to you.
Yes, it is the condition code register from the M6800 8-bit processor. I threw in an extra 'I' into my username to make it sound better. I actually used it's sister, the M6809, back in the 80's, in my first job out of school. It's CCR was EFHINZVC (if I remember correctly). It was a great processor. In fact, I much prefer the Moto processors over the IA ones.
Funny you should mention the Co-co, I didn't have that one but my very first one was the TRS80 model 3, I also had a Tandy 1000 after that one. I spent many an hour playing around with them.
I also currently work on embedded firmware, writing code for a large hi-tech firm. It's stressful but very rewarding.
Thanks for asking and its great to hear from you.
