I have a vague memory of visiting the Computer Museum when it was still at DEC, in the Marlboro building (MRO-n). About the only item I recall is a Goodyear STARAN computer (or piece of one). I found it rather surprising to have see a computer made by a tire company. I learned years later tha

[cctalk] Re: interlace [was: NTSC TV demodulator ]

I think you have that backwards. TVs use interlace. Older PC displays may do so, or not; typically the 480 line format was not interlaced but there might be high resolution modes that were. The reason was to deal with bandwidth limitations. Flat panel displays normally support a pile of input
