Quick recap, at Preston Poly they had a bunch of bbc-b's hooked upto the
PR1ME mainframe as dumb terminals via their serial ports. Each beeb had
a eprom in it called LPDFS that had two parts to it...
1. a terminal emulator (5 types to choose from)
2. a DFS like file system that used the PR1ME mainframe as storage
Now JGH has commented that it's badly written, I'm not up on 6502
assembly code so I'll bow to his judgement on that, but what I'm trying
to do is write some software that will run on linux to act as the remote
storage it expects to find.
So far not much success, I've started dissasmbling the code but my
knowledge of 6502 is limited, so I have logged what LPDFS sends for
various commands and tried to work from that end aswell.
*. sends 22,51,29,22,30,23,21,41,30,4D,31,22,0D
That sequence make any sense to anyone ?
