I just received confirmation of my registration for the upcoming PIC seminar,
along with a few brochures.

One of the brochures includes some parts I had not previously heard of, the
PIC16C74 and PIC17C44.

The PIC16C74 is apparently sort of an improved combination of the 16C64 and
16C71.  It is available in 40 and 44 pin packages like the 16C64, and has
even more memory (4K*14 program, 192*8 data).  It has an 8-channel 8-bit A/D
(presumably similar to the 4-channel A/D of the 16C71).

I hope the PICSTART-16C will program the 16C74.  I don't want to buy yet
another programmer.  (By the way, does anyone know whether the PICSTART-16B
will program the 16C58A?)

The PIC17C44 appears to be a 17C42 with more memory.  I've never been
convinced that the 17C42 was a very cost effective part, so I doubt that the
17C44 will be either.

Cheers,
Eric
