Subject: Question about 1770 DFS interface testing it on a B

I do have a copy of something that someone had created called "Utils ROM".

I think it is a copy of the 1770 DFS, but with all the disc related stuff
disabled.

As a result it will load on its own and give access to the UTILS and SRAM
commands.

It still seems to push PAGE up by &200 though.

It was possibly developed by someone related to my school to allow access to
such commands for Econet only machines.

If this is rare, or of interest to anyone, I can supply a copy.

Michael
