[QUOTE=DEATH;177050][B]Are you saying it's not possible to access the 128K machines serial port in BASIC? I can assure you that it is - I used to have my +3 talk to my Amiga, PC and 48K Spectrum/IF1.[/QUOTE]
Ditto with my +2 and Z88. -

approx 32K for the C64, 41K approx for the Speccy, less if you have an IF1 attached. BASIC starts at 23760 (near enough) in a bog standard machine, 65535-23760=41775 bytes=40.79Kb. -

Thank you, Death. That was what I was wondering about.
But, btw, how does an IF1 influence the memory ? -

Only way i know of determining the rom version is to connect up the IF1 power up the speccy and type CLOSE #0: PRINT PEEK 23729. If it prints 0 its rom is version 1, if it prints 80 then its version 2 or even 3 :D5v Transformer.I've got a 5v 3A transformer, would this be ok to use with two 3.5 inch floppy drives?
