There are *many* loader programs and they're easy to write. This
particular one was one of mine and I don't think the source ever

containing the source and one of them is surely still readable!
As well as a small stand-alone utility I wrote myself, a friend I
was working with wrote a clone of the Master rom extensions,
including SRLOAD etc, that I supplied with my Rom/Ram board.
I am suprised a sound sampler used the printer port --
there's only 2
bit of input (the ACK line). Why not use the user port?
My memory is really starting to fade. Now I think about it more, it
was an ARCHIE peripheral! :-/
It's brought off-board. It's linked to a 24
pin Blue Ribbon connector
(looks like a GPIB connecotr, but isn't the same wiring, of course) on
the back. I will certainly make a cable to link it to a printer...
I may have the proper cable. I have an ACW but I think I finally
scrapped the printer I was using with it. (One of those crummy Olivetti
inkjets - really not worth repairing)
By the way
I'm borrowing Joe Rigdon's US Beeb so I can recover the code
on my BBC 5.25" floppies, which is where the sideways RAM loading code
you were looking for is stored. Unfortunately I did't have any copies
Ah, so there is a loader program. I will dig about on the 'BBC Lives'
website, I can't believe there's nothing suitable there. If you want to transfer individual files, there is a
kermit for the beeb
(and for that matter for the ACW's 32016 side...). Kermit may not be
efficient, but it's available for anything....
I know, look in the sources of ACW kermit and see who ported it :-)
I was amazed (and depressed) that the ARM port of Kermit was simply
my ACW port with another layer added to fake out the ACW routines,
which themselves were just a veneer over BBC OSBytes! What a mess!
But my experience has been that sucking off the entire disk as an image
is not only faster, its more reliable in terms of disk errors, plus you
find interesting deleted files that way :-)

In case you're interested and/or have bits to offer, I'm trying to
preserve whatever media (docs and software) I can for some of the more
unusual Acorn odds and ends (ABC range, 32016 second processor, ARM
Evaluation Kit, Springboard etc.)
I've got some items scanned / imaged from various sources, but I'm
mainly sorting out who has what at present.
Getting archives of full sets of 'core' media together seems to be
possible; enough people have stray items around from which full sets can
be made. What's severely lacking (mainly because they would have been
severely lacking even when current, and time hasn't helped!) is any
'user land' type stuff.
I'm yet to find *anything* that was marketed for the ACW; it's possible
that PSpice ran on it, and possibly the QuickChip software (Witchy seems
to have the only surviving copy of that on an ACW, and it's
unfortunately screwed).
I've got some data suggesting rumours of an IP stack for the ARM Eval
Kit running over Econet, but unfortunately no code as of yet - I've got
some tapes yet to read though which have system backups on and may
contain something interesting...
But my experience has been that sucking off the entire

Heh, indeed. In addition, I've just been reading the password file from
an MDFS fileserver from an image of the drive so I can get access to the
real thing - people really did (do?) have things like 'password' for
their password...
cheers,
Jules
ps. Ever heard of a project called 'Squirrel'? Seems to have been some
sort of 'super-BBC' clone, but I've only got the vaguest of references
to it amongst some Acorn docs unfortunately...

I am pretty sure Reduse3 (computer algebra system) ran on the ACW or the
Beeb + 32016 coproceossr. I don't have it, I don't know anyone who's got it.

It depends on what you want to do with it. The problem is that a 40 track
image is not a lot of use to somebody with 80 track drives (and vice-versa).
