This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

A Scientific Calculator [ to remedy Acorn's omission ] ------------------------------------------------------ Docs as of 1/9/89 (PS 6 Days to my birthday!) Introduction (Very Boring!) --------------------------- The calculator is a fully algerbraic one ie. It evaluates expresions with the priorites in the following order Brackets, Power, Multiplication / Divison, Addition / Subraction. Hence 2+3*4 is 2+(3*4) = 14 rather than what Acorn's one says it is, which is (2+3)*4 = 20 (none of the calculators I have seen on the Arc do this which I would say is a fairly important feature). Also the calculator handles numbers greater then 99999999 by using 9 digits with scientific notation ( 9 digits is a compromise between the max accuracy of BBC BASIC 5, decimal fractions are not calculate to a sufficient degree of accuracy & the last place is generally wrong, and the max number of digits avaliable (10). Operation --------- Functions are avaliable by using the standard Reverse-Polish method on normal calculators ( eg 20 sin rather than sin 20 ). *** The inverse function of a key is available *** *** by clicking ADJUST rather than select *** (ie SELECT for sin, ADJUST for arcsin). Ones that are not too obvious are EXP (that is to set the exponenet in scientifc notation) which adjust gives PI (EXP also gives PI if you have not entered any digits after a clear or equals). There is also a key short cut feature. Once the mouse has been clicked on the calculator the caret is claimed ( <Escape> at any time will return it to where it was claimed from). The keyboard can then be used to input into the calc. This feature is very much in it's infancy and I haven't really decided which key maps onto which function I would REALLY appreciate feedback in this respect. So far 0,1,2,3,4,5,6,7,8,9,0,+,-,/,*,= relate to themselves(!), return is =, delete is clear, shift delete is all clear and so is # (for the number pad) and A,B,C,D,E,F relate to A,B,C,D,E,F (!) in hex mode but sin,cos,tan,1/x,log,ln in dec mode (think about it!). Every button flashes when selected, this feature is particularly useful when using the keyboard as it gives an immediate on screen feedback of any key press. Memory ------ Memory funtions avaliable are MR, M+ select, M- (adjust on M+) and Min (Memory in). If you want to clear the memory the best way is to select Clear and the Min. AC and C do NOT clear the memory. When data is in the memory the memory indicator (a small M in the top left corner of the window) goes from grey to black. Menu Options ------------ The default angular setting is Degrees but if menu is clicked over the calculator Radians can be selected (I havn't programmed gradians - because BASIC dosn't have the functions and no one I know uses them!, I think they use them in France, well at least it was by Nepolians orders that they were created! ). Bases implemented are 16,10,2 and conversion is dead easy by just selecting the base required in the menu (Your selection will be highlighted on the display bar on the top of the window). In base 16 sin, cos, tan, 1/x, log and ln become A, B, C, D, E and F for hex entry. When in bases 16 and 2 the following functions cease to work (function!) sin, cos, tan, root, 1/x, log, ln, rnd, rnd#, EXP. I have included both Fix and Sci, Fix specifies the number of decimal places to be displayed & will round off if required and Sci specifies the number of decimal places displayed (with rounding) under scientific notation. From 0 to 9 decimal places can be set. With reference to Fix & Sci, the function 'rnd' will set the internal register to the value of the displayed register (ie if you are using Fix 3 to show 3.14159265 the the display is 3.142 and on clicking rnd the register storing 3.14159265 becomes 3.142 - try it and see!). Norm unsets Fix and Sci settings. Apendix of functions -------------------- Key Select Adjust ----------------------------------------------------------- !sin! Sine (x) ! Arcsine (x) ! !cos!

Close bracket ! --- ! ----------------------------------------------------------- x is the number just entered, y is the number to be entered next. Bugs and Stuff! --------------- The largest number is of the order 1*10^32, this is BASIC's fault because it does not do extended precison arithmetic. This probably won't be fixed for a LONG while (well it IS a quite big rewrite!) but it is on the cards if lots of people want it! There is what I would call an embarrassing bug in relation to this, BASIC does not store &80000000 (ie 1<<31) in real variables perfectly and will round it off using scientific notation hence giving an error if you want to display the number as HEX or BINARY. (Of course you will also get an error if you try converting 2 * 10^20 into HEX!). Sorry about this but fixing it is loads of hassle so will probably will do it when I add hyperbolic functions and a Casio FX 6000G look alike! Finally ------- I hope that that is enough info to be able to use the calculator satisfactoraly and if any mad person would like to contact me for some strange reason like you want a bug fixed or some more functions I can be contacted at :- Eureka II (oops I mean Archive BBS!) mailbox 23 TWOC mailbox 143 Snail Mail : 6 Parklands Place,Guildford,Surrey GU1 2PS.
