The disks listed will each fit onto one side of an 80 track DFS disk.

archived files and Andrew Black's Archive program to extract them. On
HADFS and ADFS disks, I can fit several of the listed disks on one actual
disk by adding up the sizes. I can handle DFS 40/80 SS/DS, ADFS format L

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Always label your disks, eg "DFS 40 track" or "HADFS 400k", especially if
you can only use one side, or only have a 40 track drive.  If disks are
unmarked, I will assume them to be 80 track double sided.  The disk
formats that I can handle are:

5.25 inch:      DFS 40/80       ADFS 640k       HADFS 200k/400k
3.5 inch:       DFS 40/80       ADFS 640k       HADFS 200k/400k
3 inch:           DFS 40                          HADFS 100k

I cannot as yet supply 3 inch disks.

Your name and address will be added to a database for the sole purpose of
maintaining this library.  I will not release this address list to any
third party.

************           EPROM programming service              ************

If you send a disk with a rom image on it and an EPROM and I will program
it. Alternatively, I can supply the EPROMs.  The costs for these are:

Programming:            £1.00 each
Supply of EPROMS:       £4.00 each

So, if you send a disk with an image on, and want four roms programmed
with it, that is £1.00 + 4*£4.00 = £17.00.  If you supply the four roms,
it is 4*£1.00 = £4.00.

Roms I can program are:
2764    8k              27128   16k             27256   32k

A handy way of posting (and storing) EPROMs is to put them on a piece of
anti-static foam and putting them into the small plastic tubes that 35mm
roll films come in.  Piggy-backing them, you can get four in like this.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

A lot of the items in this library are my own programs.  If you want to
contribute programs, send a disk to the above address, clearly marked with
your name and address.  Make sure you enclose your name and address so you
can be credited.

It would be handy if you could do the following:

        {*}  Supply some sort of instructions, preferably on disk.
        {*}  State what machines it can run on, and what it needs (eg
DFS).

I will attempt to test all the programs I receive to see how many machines
it will run on.  I will also test to see if it will run on networked
machines.  This library is primarily for the 8-bit Acorn machines, but I
will also test for Archimedes compatibility.  Don't be put off by this, if
you think I might frown on something because it has some incompatability,
send it anyway.

Group, a postal user group dedicated to supporting the BBC and Master
series computers.  It can be contacted at:
