Thesebattery units are supposed to beavailable from all ACORN dealers at aprice of about 4.50 £4.99. The batteryis to provide backup to maintain thecontents of CMOS RAM at all times whenthe computer is disconnected from themains power supply. The battery lifeunder 'NORMAL' operating conditions issupposed to be approximately one year.As yet I have to replace my batteryunit and the computer is now some twoyears old. I think there is something in what yousay about the more you use the computerthe longer the battery will last. Onecan assume that if the computer is runcontinuously then the battery will onlyrequire replacement when it dies of oldage due to internal reaction. Incidentally at the front of theWELCOME GUIDE there are details of howto change the battery unit and thissupercedes the information given onpage 242. It seems quite a job and thebest advice I can think of is to keepon using the computer. To : 999 (All) From : 0E7 (Fred Nevin) Subject: ADFS FILE ATTRIBUTES I believe that everyone has some and Iexpect you all know better than I thatFiles on disc have four.(I hope) They are:- (L) to lock files to prevent anywriting to the file. (W) to accept writing to the file (R) to accept reading of the file These are or can be used in variouscombinations to control ACCESS to thefiles on disc. There remains another attribute whichis of very dubious benefit if any atall, that is (E) which allows a file tobe executed/read only and thisattribute CANNOT be altered by normal*ACCESS. Sorry to be so long in getting to thepoint but HELP!!!.HELP!!!.HELP!!!. Whilst inputting an M/C programme andgetting it to function rather thanmalfunction I obviously RAN the programme to obtain the code and foundthere were some typing errors (Well,what else can you expect). These werecorrected and it was not till muchlater I discovered that some otherfiles on the disc (of whichunfortunately I have no backup) had hadtheir Attributes changed from LWR tothe dreaded E which I ' Attribute' tothe faulty M/C. How do I get rid of theE Attribute and get back to LWR. Iremember a long time ago about 7-8years or so a programme was publishedin the Acorn User to overcome thisproblem. Does anyone have a copy of theprogramme that they can let me haveplease or has anyone written one. Anysuggestions apart from the one that youshould always input programmes ontoblank discs to prevent this happeningor keep a backup will be most welcome.
Editor... I now realise that the
CATALOGUE item in issue 25 had a
fragment missing. The E attribute.
Well, if you refer back to that article
and remember how the filenames and
attributes etc are stored, from &C405
in blocks of 26, then it is easy to see
the 5th byte of the name marks whether
the E attribute is set or not. If this
byte is above 128 then the E attribute
is set. If this is so, then just remove
128 from it and save the catalogue back
to disc. The program Eoff! on this disc
will do this for you. If the E
attribute is set in a sub-directory,
you will have to enter that directory
before running the program. Thanks for
pointing it out Fred!

To load in a ROM image from disk, Ihave to use the following commands,which I would need to incorporate inthe program: ?&FF3<ram no. IN HEX>=0 (eg ?&FF31=0clears RAM bank 1) *LOAD <fsp> 8000 followed by a press of<BREAK> (I have only got RAM banks 0 to 3) This would be very helpful, as I couldthen also use it to load into sidewaysRAM any commercial games which use thiscommand, although I would have to beable to substitute the third variable (RAM letter, if I am informed correctly)for a number 0 to 3 within the SRLOADroutine.
