Ok for anyone interested here's the repair log for the Asteroids Deluxe.

I think I got everything included here.

Asteroids Deluxe repair log

Upon power up got nothing.

Hooked up Fluke and checked Rom/Ram

Could read the Vector Side ok, but nothing from Program side.

Found Dead ls139 @ L2

Could now read program side, but not vector.

Seems Some of the pins on L2 were stuck so I could read the Vector side but
upon replacement
they were no longer stuck.

Found Bad ls157's at F2, H2, J2, and K2 replaced and can no read Vector, and
Program sides ok

However there were bad eproms @ D1, E/F1, F/H1, and R2 Burned new ones.

Power up and get watchdog.

Remove pin 1 from LS42 at L5 game now plays blind, but with some strange
explosion sounds
and no thrust sound, just a faint pop.

Start troubleshooting VSM

Ground watchdog Disable, and game plays blind as well.

Pull and check custom prom @ C8 checks good.

Find bad Ls193 @ J4, and K4

Now greated with a horrible picture.

Found K9 pin 3 stuck that cleared up the diag lines

Scaling is wrong for ships, and it appears there are no medium asteroids.
Found bad ls175 @ M6

Having problems with Highscore table. When going into game mode, it would
display BFBFBF
while trying to load the top 3 scores. Found bad ls174 @ N10 but then the
table would
now try to load FFFFFF also found bad ls244 @ M9 and bad Earam.

Highscore table now works. Onto the sound problems.

Well there was definitely a problem in the Z Pin 3 of K9 was stuck, as for
the asteroid size, Stuck Pin 2 at M6.

Now to figure out why the explosions sound like the ball hitting a pong
paddle.

P6, P7, R7 and the associated Nor, Or and Buffers are good..

The camera caught the Press Start when it was blinking. It looks normal,
not on the picture.

One other thing I've noticed, is there seems to be no medium asteroids. They
go from large to small when shot.

Wild guess, looks like Z-axis (brightness) is backwards. "Press start"
should be brightest, diagonals should be invisible.

Been working on a very dead Asteroids Deluxe. I've finally got picture. In
game mode I've got a vertical line going up form the center, then angling
off to the upper right. I also have diagonal lines under the zero scores.

In test mode I have 4 0's on the upper dip switch settings then a diagonal
line for the 5th, Looking at the manual I think there should be only 4 0's
on both dip switch lines, but the bottom has 5.
