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.

Formugraph. By Steven Insley. Aged 15 �1994 History ------- NB: Version numbers are not included as I didn't make notes on them. However since no version before this has been released, you should not have a copy :-) > WIMP skeleton writen. > First template file created with display window only. > Program changed to include icon creation and sprite plotting. > Program changed to allow writing to sprite from within program. Production halted here as I had no idea what the program was going to turn out to be! This was only ever intended to be a test program to see if I could plot sprites in a window and alter them. After sorting out my immense collection of old magazines, leaflets and general junk :-) I started reading one of the magazines. I came across an article on plotting these 3D graphs. I remembered typing it in on my old BBC Master with my friend Rupert, so I went through my discs trying to find it. The only way to change what was produced was to alter the formulae inside the program. I then cracked on the idea of writing a wimp program that produced similar graphs in the WIMP, using the sprite plotting program written earlier........ > Wrote a graph plotting routine on the Arc that single tasked. > After entering some of the formulae that were in the magazine, I became puzzled why the graphs were out of proportion :-| but this was easily solved by multiplying the screen co-ords by various numbers ;-) > Inserted the now half complete plotting routine into the WIMP program. > Created the input window. > Plotting routine changed to write to sprite rather than screen. > Plotting routine changed to read in the formulae from the window and use those instead of pre-programmed ones. > Created stylish info box. > Made save boxes for saving formulae and display. > Made menu contain the 'Reset' option. > Altered the program to handle the windows and the sprite plotting more smoothly and with less commands. :-) > Went to AcornUser Harrogate show '94 ! > Showed program so far to a nice man on the Acorn User center stand. > He liked it... > Went home a poor, happy man. > Started the Sequence code after making the templates. > Had MAJOR problems with OS_SpriteOp. You name it, it went wrong! �-( > Ignored the problems and went on to create a save box for the sequence formula. > Made the 'Rendering...' window but didn't implement it for some reason? (forgot about it! :-|) > Went back and thought HARD about the SpriteOp problems. > Fixed it, realising how OBVIOUS (not) the mistakes were. > Had a problem with the number of frames produced. If 1 was put in 2 frames were produced. If then number of frames was not a factor of the difference between the two loop extremes, an extra frame was produced. > Altered the way the loops were ordered, making the 'frame being rendered' loop the outside one. This solved the problem. > Implemented the 'Rendering...' window. > Added the 'To input' and 'To Sequence' options on the menus. > I realised that if all the sequence formulae did was produce a series of sprites on disc, then many people would not be able to see the animation, especially if they had little or no knowledge of system sprites or BASIC. I had used !Convert by Mark Moxon & Robin Barnes, that appeared on a previous issue of BAU along with the morphing program; to create a movie file. I decided that leaving instructions to do this was unacceptable, so I came up with the idea of making the program save an application that would load all the sprites up from within its directory and animate them. I started creating an app. that would do this. > Added the Paste Function window. > Had problems with the sprite that is used to add an icon to the app. in the directory viewer. Figured out the position that the sprite name is held at in the file so I could alter it directly. > Added DragASprite. > Added the interactive help messages using Message_Trans. > Redesigned some of the windows to make them neater. > Made the 2D windows just for those old fashioned types. > Wrote Docs. > Jazzed up the sequence app to include nice backgrounds and borders. > Made the sequence app include a speed bar. > Finally breathed a sigh of relief that the first release version was finished after a months of grief. :-) By the way... If any one finds a PROPER use for this program, not just making animations and screens because they look pretty, write to me at the address in the ReadMe file.
