Assorted parts, round 2
- The first round of parts has completed, so whatever's left is up for
grabs. I found another two 1869/1870 sets, two SCP1802LE CPUs, and a
rather rare find (first time I've seen any) of 12 CDP1862CEs. These are
the color generators that go with the '61. To see what's available,
check < http://tinymicros.com/1802 >. E-mail me for any parts you
want. First come, first serve. Anything left over this time next week
hits eBay. Remember that data sheets for most of these parts are
available at < http://www.cosmacelf.com/docs.htm >.

anyone who missed a 1861: you can use the 1864 just like a 1861 (see
the data sheet); only difference is the frame rate of 50 Hz instead
of 60 Hz for NTSC TV. But most tv sets and monitors can handle this
difference without problems.
If you combine the 1864 system schematic from the data sheet with
the NTSC color encoder from the 1862 data sheet, you can even make a
NTSC color variant- the farme rate is still off, but (in theory) it
And, just to note: As we know it from COSMAC stuff, the color
encoders are astonishingly simple.
