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.

The PIC16C84 is a programmable micro controller.
Applications to generate source code and blow the chip with it are avaliable from the same author.
This application takes an object code file and emulates the chip but not in real time.
There are two windows, Control and Monitor. The menu controls which are opened
when you click the icon bar.
Dragging a HEX file into the control window or icon bar loads the code and performs
a power up reset.
All the memory and register indicators are in writable icons. There values can be changed
at any time by clicking on the box to get the carrat, typing in the new value (in HEX)
and then hiting RETURN. Note new values are only used when RETURN is hit.
The WDTE icon is the configuration fuse for the Watchdog Timer Enable, with this ticked
the watch dog timer will increment every programme cycle.
You can choose to single step through instructions or have them continiously exicuited.
Alternativly selecting Skip will move to the next memory location. Note that you can
perform a GOTO by typing the required value in the address box.
The Sleep LED lights up when in the sleep mode, then only the watch dog timer runs.
The Monitor windows only shows values of registers that have been written to. You
can change the value of any register simply by typing a value (in hex) and pressing return.
There are some psudo registers to help compensate for the unreal time of the emulator,
as most applications have long time delays, these are 'watchdog time out' and 'Eprom Time'.
The 'watchdog time out' is the limit to which the Watch dog timer must reach before
triping, it is preset to the approximate number of cycles the real timer would take.
However if you want to speed things up simply type a smaller number here.
The 'Eprom Time' is the number of machine cycles before data is written into the
Data memory. This takes time in the chip but here is done instantly. However, the interrupt
on time out still occours. To make this happen faster type a smaller number in here. Note that
in the data sheets a certian uninterrupted sequnce of operations is needed for a sucessfull write,
here only the last stage of setting the write bit in EECON1 (with it previously being cleared)
is required.
You can't access the prescaler in the real chip here you can, it counts up in increments
depending on the prescaller division ratio. For example with a 1:4 ratio it will count up in
increments of 40h.
Break points: To set a break point type in the hex address and press enter.
To clear a break point enter and address greater than the maximum of 3FF
When a running program encounters a break point it will stop and go into the
single step mode.
With such a complex application it is not possable to test it sufficently to find any discrepancies
between its action and that of the real chip. If you come accross any of these please let me know
at the address or emale given at the top of the page.
Legal stuff.

or anything this program may or may not do.
