Re: BBC BASIC: nearly had no line number. could it have saved space by virtual line no's?

COMAL is pretty similar to BASIC. It doesn't need line numbers, but does use them. It has FORTRAN like labels for GOTOs, and PROCs just like BBC BASIC. I've got the manual, but my scanning list is huge and whilst on my list, I have no idea when I'll get around to scanning it :(

OK, there's getting to be a bit of a proliferation of these "wouldn't x have been better" "why didn't they do x" "where's the x" threads now. This clearly belongs in the "Elk full beeb" thread. I'm going to move anything in this thread to there once I get a mo...

As you've got a compact, you've got sideways RAM so can load either logotron or acornsoft logo from a floppy into a sideways RAM bank. Do you have a...

Re: Sockets at the back.

Disk is for a normal 3.5" drive(s). Don't connect anything else to it, you'll need the appropriate lead too - http://mdfs.net/Docs/Comp/BBC/Disk/#compact

RS232 - It's a serial port. You could connect it to another serial port on something else (e.g. printer, modem etc). :)

The CMOS ICs can go horribly south in them - buzz out the circuit, check the resistors near the battery, and the surface mount capacitor. Assuming everything OK there, it's time to replace the CMOS IC...

Hello, The one I was repairing is still sat on my repair bench, I really haven't got the time/inclination to finish it up (or space to keep it).
