It is hosted on google code, a dying service. FreePascal(coffee) OS.A more basic version is posted there.I assume it works as the version that I last built did not for some reason. Sources should be there via subversion checkout.Thats what I tested with. https://code.google.com/p/coffee-os/
It uses a basic VRAM scroll buffer and writes to it. Examples are found elsewhere in C. (OS Dev pages) Im in the middle of a fedup upgrade at the moment, but will see what I can do.

The terminal does not oblige the Pascal OS code to scroll the output. Virtualbox emulation works, so this must be a qemu bug. Using QEMU in KVM mode as Ubuntu LTS. Source line to trip bug(in theory pushes VideoMem up one line): procedure Scroll; //this is whats causing crashes.
