8 Bit To: 999 + 483 (Daniel G Shimmin) From: 15A (Steven Flintham) Subject: JANET email in issue 29 I thought this was quite interesting, although it does make me feel rather worried at how little I actually seem to know about things! I appreciate that this is hardly a novel suggestion, but why not put your collection of email onto a TBI/XBI discin its original form. You could perhapsput a separate 'article' on that disc with any comments, rather than interspersing them with the messages, which I found a bit confusing. If this isn't practical, I'd certainly like to see some more in a future edition of 8BS. A program which uses the Master's shadow RAM to provide a 640x512 mode is mentioned in the article - do you have or could you obtain a copy of this? I would be very interested in seeing it. I wrote a crude program likethis myself - it was just an interrupt routine to switch between the two banksevery VSYNC and relied on the programmer to create the display correctly. I never bothered finishing it because I felt it was too much effort to write routines to plot text onto it at any appreciable speed.

"Out of sight, out of mind." When translated into Russian by computer, then back again, became "Invisible maniac" A schoolgirl answered the question "In which countries are elephants found?" "Elephants are very large and intelligent animals and are seldom lost" The Duke of Edinburgh (At the English Speaking Union) said, "I include "pidgin-english" even thoughI am referred to in that splendid language as "Fella belong Mrs. Queen" To : 19F + all PC/Arch owners From : 483 (Daniel Shimmin) Re : PC's and Archimedes Silas Brown comments as follows. Firstly, to program a PC you'll need a software package. Sometimes some are supplied; try typing DEBUG, GWBASIC, BASICA or QBASIC. Secondly, the figures 70, 90 etc. are access times in nanoseconds, you shouldchoose the one which matches the specification of your existing system and memory. Members with less-powerful PC's (up to 386) might wish to consider trying somesoftware from Alan Blundell's BBC PD, which has a large (compacted) selectionof PC software in its Master 512 section. In addition, I thought it might be a good idea for a list to be compiled of the addresses and/or phone numbers of members who have PC's and who would wish to contact other PC-owning membersto swap software, tips etc. Anyone wishing to be included on this list please let Chris know next time you write. Finally, can anyone with any ArchimedesPD or info of convenient size (less than 150K) send it in to Chris (in ready-to-run form) for inclusion on theADFS version, to start up our long-awaited Archimedes section.

Replay rom MKII works with 1770/2 DFS and ADFS I'm not quite sure about 8271 but I should think so, this will copy any tape and most discs but the discs will only work on the machine that the Replay rom is fitted to. It has built in editing so that you canalter a game or add cheats. It holds up to 8 games on one side of adisc. The reason I'm selling it is thatit cannot be used with a Winchester. Its boxed and comes with a manual. I want a tenner for it. Viglen 40 track double sided disc driveworks off BBC power supply, in good working order `10. WANTED....

To: 999 (all members) From: K2C(Frank Jones) Subject: Fault Finding
I am the owner of an Issue 4 BEEB, no
modifications with a faulty screen
On switching on, the screen presents a
few small squares, haphazardly placed.
At the top left hand of the screen there
is no BBC 32K etc or cursor, only an
hyphen. Continually tapping of the
key will see the hyphen descend the
screen until reaching TAB 20; there the
cursor appears in either Mode 6 or 7.
One is now able to type a program in and
run it. Any syntax or error messages
appear and all this activity takes place
in the lower part of the screen. A
change of mode might see the print or
size change but chaos returns to the
screen and one has to press BREAK,tap th
e RETURN key and accept Mode 7 and the
bottom four lines of the screen.
Not wishing to spend a lot of money in
sending the BEEB away, I am wondering if
with the knowledge and advice of fellow
members, I can repair it myself.
My sources of information are page 498
of the 'User Guide' (regretfully, I have
not yet got a copy of the 'Advanced
User Guide') and pages 32/33 of
"Choosing and Using your Home Computer";
the latter being the most useful
featuring a double page coloured layout
of the inside of the BEEB.
From the above sources, Am I naive in
suspecting the VIDEO CONTROLLER, this
is chip ref HD46505SP which is described
as "The chip takes information from the
user memory and converts it into a video
signal for display" or does the trouble
lie before that and the chip is
producing only what it is sent?
I have examined Watford Electronics and
Bells Computers' list of chips available
and neither features this particular one

To 483 and 999 From 3PM Subject Copyright This does seem a thorny subject. I appreciate your comments. Apart from flagrant plagiarism, the use of code inwhat is now a near commercially obsolete processor would seem to be unlikely to offend. And hands-up anyonewho can write a couple of lines that somebody hasn't published somewhere. I think I will just simply acknowledge any known source and be damned. All publication is after all 99.9% previousgenerations building blocks. Did Henry Ford insist that GM handbooks showed their cars with square wheels?. To 20G, 483 and 999 From 3PM Subject Savings: in answer to your problem, the value V of £P at R% compound interest after n years is:- V=P*(1+R/100)^n Sometimes a yearly interest rate is offered but interest is added calendar monthly in which case R is taken as theannual rate/12 and n is now the number of months. Try it out and you will see that 1% per month for 12 months is better than 12% per annum. Go for it. Regarding maths it's only shorthand really with a few rules thrown in, the telly thrown out, and the secrets of the universe are yours for the asking. You can even save energy (a popular subject?) with humble arithmetic. eg. 20 million tellies*100Watts=2,000 Megawatts=8*Dounreay Fast Breeder Reactors.

Issue four was the last complete updatehowever System bank was updated around issue 7 but was only issued on request and for some unknown reason never released on an 8-bit issue. Systems Server was also updated and canbe found on issue 14.
