Re: [Avid-L2] Re: New Mac Pro

There was a technique if you had the programmers panel to see exactly where your active data ended but I didn't have one of those.

I only recall a start address to start loading to, I probably still have a manual in the UK ill call my dad and see if its easy to see on a shelf!

Best regards

I remember examing the cells, or whatever the proper term is, and then reentering those numbers on restart to keep the existing edl. Working of an LPT terminal with the snail trail paper. And the fun of loading the boot strap program before the main program off paper tape. That was always a scary time for me.

I still have my Cardac cardboard slide device to teach you how to increment the program counter by one and execute an instruction or read the data depending on where you are in the cycle of things. Guys like the late Dave Bargin knew what I'm talking about. As your post alludes to the higher level languages that are abstractions of real machine language are never a efficient as the real thing. With my limited knowledge in the area I would liken it to learning to drive an automatic first. Rarely do those people go back and learn the nuts and bolts of a manual transmission. You might ask why should they? But like the Dead Heads say, "If you gotta ask....."
