In my ROM archive (see:
http://8-bit.summerfield-technology.co.uk/bbc/bbc-software.html )
I have:
DFS AMAB 1.10 (earliest released version?)
DFS 1.10
DFS 1.30 (several versions with same version no.)
DFS 1.40 (several versions with same version no.)
DFS 1.41
DFS 1.42
DFS 1.43 (several versions with same version no.)
DFS 1.43a (page=&1500, probably hacked)
DFS 1.44 (several versions with same version no.)
DDFS 1.40 (1984)
DDFS 1.50 (1984)
DDFS 1.53 (1985)
DDFS+ 0.91 (1985, for the new Acorn compatible 1770 interface I
presume)
DDFS 1.54T (1987)
Missing is for example DFS 1.20 (mentioned in the text of 1.41:
DFS 1.41 S/N 34562. The end of DFS mesage is again in evidence. This
time, we are vaguely hopeful of a review from Acorn User, now that Acorn
are close to the wall. But maybe that is still too much to hope for.
Even if it was reveiwed, they would probably review the version given to
them nearly two years ago. Things have changed since then! There have
been allegations that *HELP SPACE is ripped off from Acorn User May
1984. Our feature appeared some months earlier in DFS 1.2, so if anyone
has ripped anyone off, it's the other way around. Personally, I never
read the gutter press. There are now enough commands in DFS, anything
else we can think of adding has either limited use, or does not really
belong in a DFS (ie not disc related). With respect to upgrades, as most
know WE charge for upgrades, so I reccomend you do not upgrade unless
you have a problem with your current version. Regrettably bugs are still
showing up, but most new bugs are noticed by very few owners. TTFN Andy.
(c) 1983
Also note that the messages are not always the same (or even present) in
those same-numbered versions...
If anyone has more ROM images (any, not just Watford DFS) that don't
originate from 'the bbc lives' I'd be interested in them to update the
archive...
