Yes, you get the same kind of thing on some TRS-80 Model 1 16k games when the cassette out line is plugged into a speaker. No sound chips...all done in software...all in assembly language. Amazing.

I had a gander at the Apple IIe international

Its an above average condition example, no scratches and no uneven yellowing, in fact very little yellowing at all!

Has colour composite monitor which has the usual slightly geometry destortions that these monitors have after 30 years

No vivid pen or soldering iron engravings that these often have.
