Intel OS DOC and SOURCE

Well, I like my scanner because it has a sheetfeeder and because it's legal
size, but, alas, it's only capable of a limited range of formats. After
all, I've had the thing for nearly ten years. Now, if you have a way to
massage the old style TIFF (targa) files into something better, perhaps that
would be the thing to do.

A lot depends on what requirements the TBD web host will have, and I'll
perhaps hold off until a site is found.

OTOH, I did sort of allow that since Hans Franke is going to be at the VCF,
though I'm not, I can arrange to get this stuff hauled out there for him by
someone from here who's going. I will have to see whether he's willing to
get this stuff scanned and appropriately compressed, then made available via
the web.

Wait and see . . .

Dick
