Question for the vintage computing enthusiasts out there:
A friend of mine has acquired a Sinclair Spectrum, but it only has PAL RF output.
Living in the US, he needs NTSC output.
Has anyone come up with a good solution for that?

A 1985 issue of SUM (Spectrum Users Magazine) suggests the following:
"The poor man's way is to change out the color burst crystal. The computer comes with a 4.43 MHZ crystal which is the frequency used in the PAL TV system. With NTSC, the frequency is 3.579545 MHZ, so run down to your local electronics parts store and pick one up (Radio Shack sells them for around $1) and swap crystals out."
