8 Bit To: 999 (all members) From: K2B (Colin Culpitt-Smith) Subject: Z88 Users - useful aid If you would like to have proof that your mains adaptor REALLY is powering your Z88 - as opposed to just hoping - then I have a very simple mod to the adaptor suitable for anyone with modest electronics experience. If you have none, then I will adapt it for youfor only `3 inc return postage. With my mod, your adaptor will light a red LED whenever the Z88 is switched on, and doesn't simply show that the adaptor is powered from the mains. This way you know the Z88 is being mains powered and saving your batteries. Ring me for details on 0738 812186 anytime.

That is, without lots of boring and slow editing & deleting etc! I've written a program that uses the WW+ language, and it edits out all those %codes, extra spaces & returns etc, and converts a messy layout into a normal WW+ layout - all at the press of a key! If you would like a copy, please send me a disk with your typical Z88 text file(s) on it, and I'll send you my program, customised to suit your text files. Please ensure the Z88 file(s) are not converted for the BBC, & not saved as Plain Text on the Z88 - i.e. exactly as originally typed, complete with all Z88 codes & commands etc. Send disk with sae to:- 35 Muirmont Crescent, Bridge of Earn, Perth, PH2 9RG NOTE: only OK for WWplus, not WW! From: K5B (David J.MacGraw) Subject: Using ViewSheet with ADFS. A tip for using ADFS linking files: The root-like structure of an ADFS directory only permits the downward referencing of ViewSheet linking files e.g. 'V.VS1' where 'V' is sub-ordinate to the current directory. This is a disadvantage where several Sheets need to access a common set of figures e.g. component costs, operator rates etc. This isn't a problem with the DFS as all directories have a parallel level. By changing 1 byte in the ViewSheet rom, linking files can be 'above' the Sheet, or even in the Root directory of a more complex structure. ViewSheet vB1.0 (as supplied with the Master 128) is part of the 'MegaRom' but can be copied onto a separate 27128 Eprom and used in a cartridge, '*UnPlugging' the original image. Alternatively, it can be run from SWRAM, provided it can be made 'read- only' after loading, as the image is written to during use causing a crash! The byte to change is at offset &2979 and is the 'V' of the 'V.VS' filename. Altering this to '^.VS' accesses files 'above' the current level and '$.VS' accesses linking files in the Root. From: K5B (David J.MacGraw) Subject: More SWRAM in a Master. Master 128 cartridges will accept RAM chips as well as Eproms and can thus be used to add more SWRAM. The chips can be either 6264 (8K x 8) or 62256 (32K x 8, only 16K of which is used) or equivalent CMOS byte-wide chips. The Master *SR commands only recognise positions 4 to 7 (the cartridge slots being 0 to 3) so a utility rom such as ADU by Pineapple Software needs to be used to make best use of this feature.

Who can help? To: 999 (all members) From: K3H (ALBERT SCHOFIELD) Subject: TAPE TO DISC ON THE BBC B Anyone who has used the cassette filing system will be familiar with control codes in the file names. These appear as queries (?) no matter what the control code is. Control codes cannot be used in disc filenames as they confuse the DFS. However, the control codes can usually be dispensed with when transferring files to disc but occasionally a file will not work without the control codes and this causes problems when transferred to disc. There are various ways of getting round this, so to illustrate one method I will give details of how to transfer one such program to disc. The program is ATOM SMASHER which is in four parts :- ATOM-SMASH, INST???, M/C???? and MAIN?. The file that causes the problem is the third one M/C????. The first file is a short loader for the second file which is really only a basic program with protection so the first file can be dispensed with and the second file made listable by the following routine. Load the second file, INST???, from cassette by using *LOAD""18E0 . Then enter:- ?&227A=&FF to set the end of file marker. If page is normally at &1900 you should now be able to list the file, otherwise set page to &1900 first. Delete line 308 which is CALL&1790. Also delete line 310 which is *RUN. Add the following line:- 5 IF PAGE<>&2000THEN PAGE=&2000: CHAIN"INSTRUC" . This is necessary to make room for the next file to download. Alter line 760 which is CHAIN"" to 760*M/C. Add line, 770 PAGE=&E00:RUN Now save the file to disc as INSTRUC . The last two files are machine code and load in below &1100 so they can be combined into one file so that they can be downloaded together. To do this load the third file from cassette with:- *LOAD""1900 . Then load in the last file with:- *LOAD""1E00 . Save it to disc with:- *SAVE M/C 1900+F00 BBA 900 . This file will have to be downloaded to &900 so use whatever method you prefer. By chaining INSTRUC the instructions will be displayed but the game itself will not work because the control codes have not been entered. You can prove this by cataloguing a block or two of the third file from cassette. Press BREAK and chain INSTRUC . The game will now work. To identify the control codes catalogue a block or two of the third file, M/C????, press BREAK and enter:- *SAVE MEMORY 0 400 . This will save the first four pages of memory. Then *DUMP MEMORY and at location &3B2 can be seen the file name and the three control numbers. The fourth is just a query. Make a note of the seven numbers:- 4D 2F 43 98 80 8A 3F. These can be poked into memory by adding an extra line to the file INSTRUC just before it loads the next file as follows:- 756 !&3B2=&432F4D:!&3B5=&3F8A8098 See page 409 of the USER GUIDE. It is possible that slightly different versions of the game exist. If so you will have to make allowances for this. More next month.

To: 15A/999 (Steven Flintham) From: K5U (Simon Godfrey) Subject: BT-approved modems (8BS£40)
Regarding your query on modems,
providing you use a short and high-
quality comms-lead, and a fast comms
program then you should be able to
connect your Beeb to a 14400 modem at
the BBC's maximum speed of 19200 baud.
The modem will then communicate with
the computer at this speed while it
communicates over the phone line at
a maximum of 14400 baud.
Many modems are not 'BT approved'
simply because it costs the
manufacturer so much to get the
approval from them. If you can find a
cheap modem that has been approved for
use in the USA then it should be safe
enough to use on a BT line as
(apparently) the U.S. standards are
higher than BT's.
The use of such a modem may however
infringe your license agreement with
BT. It's your choice - It could be the
difference between `90 and `140...

The program is designed to accept the
last 3 digits of the mileometer
reading. Thus the 1000s are ignored.
This will fail if the vehicle can do
more than 1000 miles between fill-ups
(FULL to FULL). The program adjusts
where the mileometer reading passes
through XX000, ie "Previous mileage
900", "This mileage 100", will give a
reading of 200 miles. (See lines 510 &
520). The program is also designed to
give two places of decimals in mpg
calculations (see lines 550 & 720).
These must be switched off (lines 640 &
800) or dates, miles etc would be given
two places of decimals (eg 12.00
instead of 12).
