I recently purchased an expansion port and Acornsoft's ISO-PASCAL cartridge with a view to do a little programming in this language. Unfortunately, when I attempt to compile the source file I get the message "Undefined file" appearing on the screen. I'm not sure if this is due to my incompetence or some problem with the machine.
Secondly, I have a serial printer which I would like to use on the Electron which has a parallel port. Is there any way round this apart from buying a parallel port for the printer?
Any advice on these matters would be greatly appreciated.
