Last night I bought a Commodore 1702 color monitor at TOYS-R-US for
260 dollars.  The 1702 has been very hard to find around here (western
suburbs of Chicago.)  K-mart advertised them on sale, but they don't
have them.  (The clerk acted like we were crazy for thinking the adverisment
implied they were in stock.)

Anyway, it works real nice with my 8-pronged (v2, right?) c64. No wavy
screen. By the way, I agree with the consensus of answers to my query
on that problem that it is due to power supply ripple in the RF output.
Also, I misstated the parameters of the "wave". The lateral movement of
the characters is about 2 pixels, much less than the 1/2 character I
had estimated. The frequency is more like 2 per second than 1 per 2 seconds.
That's moot as far as I'm concerned now.

Regarding the characters generated by the "port 1" joystick. (I think
that's the one near the keyboard) , I don't think it "slows the machine
down" as Ray Miller stated. I found that it didn't affect the FROGGER
between-game display at all. Oh, I'm talking about the left position
that generates the CNTL character.  When I ran a sprite back and forth
from BASIC, it moved slightly slower to the left than to the right,
but this was nothing like the factor of ~10 times slower observed with
print loops. Anyway, it is a royal pain!

Is anybody else a GOBLIN fan out there. This is a simple public domain
game that runs out of BASIC using characters. The player's character
marches upward through a maze of blocks. The player controls the
lateral movement with the "o" and "p" keys. The movement wraps around
top to bottom and right to left (and left to right.)  The object is
to march over all 36 victim characters, which are scattered throughout
the maze, without running into a block. Great fun. The maze is different
every time so there is some variety.

I programmed a MASTERMIND game (who hasn't?) which I like because of
all the delicious colors I get to sit there and stare at. I also made
a swordfight game. The two duelists move back and forth (fixed y) and
thrust with the fire button. The sword stays out for 1 second, followed
by 1/2 second of vulnerable "dead time". It's simple but amusing. My son
and I designed the figures using  a simple sprite editor I wrote. My
daughter does show signs of "computer anxiety" or whatever, but she does
play with it. She tends to defer to her brother if she thinks she can't
outshine him as befits her superior age.

I didn't have any problem using the collision detection, as somebody
warned was the case with the v2, which I think I have. I avoided the CNTRL
character by using up and down to move the sprites back and forth.


So we're all having great fun. I just love the color!
