From Oliver Debus
Dear 8-Bit Software Members,
I have collected technical information on the "BBC Micro Series" and
"Acorn Electron" computers. I want to make these available to you so
that you can repair, program or design your own hardware for the BBC
Micro. I'd like to thank Acorn for supplying me with most of the
information I can now provide.
Like Chris Richardson I don't want to make any financial profit out of
this service but I have to charge to cover the cost of photocopying and
sending. Unfortunately postage here in Germany is very expensive,
which is why many companies here have already started to send their
post from abroad (Holland etc.) where it is cheaper. Anyway I have set
up a list of what I have and if anybody wants to provide the service
and thinks that he or she can provide it cheaper I'll let him or her do
it - OK!?

Ordering Information:
---------------------
In order to tell me what you require please specify
(1) the Type and No
e.g.: "FW 1" if you want the ADFS Application Note
(2) how many sheets (A4s) these are in total
(3) the cost in pounds (the amount you enclose in stamps)
The Postage & Packing Costs can be calculated from the following tables
and formula:
weight of 1 A4 sheet = 5g
weight price type number of sheets that go in
-----------------------------------------------------------------
5 g 5 pence normal envelope 3 A4s
10 g 7 pence A5 envelope 20 A4s
25 g 10 pence 60 A4s
Step 1: (Postage)
Please multiply the no of A4 sheets by 5g and add the weight
of the envelope you require (see above table). Use that weight in
the table below to see how much the postage is. Add the cost of the
envelope (see above) to the postage and you got the cost for p&p.
weight postage in pounds sterling (2.4 DM = 1 pound)
-----------------------------------------------------------------
0 to 20 g 0.42
20 to 50 g 1.25
50 to 100 g 2.08
100 to 250 g 3.33
250 to 500 g 5.0
Step 2: (Photocopies)
Please multiply the number of photocopies (A4s) by 4p (4 pence per
photocopy).
Step 3: (Total)
Add the cost of the photocopies and the cost of p&p, now you have the
total cost which you should enclose in stamps together with your order.
