Galaxian PCB conversion - What is it?

I ran across a Galaxian PCB at an operator's place a
while back (picked it up along with some other items).
It was hacked into something else, but I'm not sure
what???

The CPU socket was removed and replaced with a light
Tan colored block that I'm assuming is the CPU sealed
inside of it (ala Pac-Man Plus). It says "EX-PAK
CVS Technology Copyright 1984" on the top.

There are numerous chips piggy-backed around the board
with wires running various directions (it looks like
they did a fairly clean job, so the board could be
send back to a Galaxian). The two ROMs at the end of
the PCB (row 1) are also piggy-packed (so 4 PROMs
total), with wires tying to another chip midway-up the
PCB. The labels on them are hand written and either
say "OFG" or "DFG", I believe.

The normal Galaxian daughterboard is missing and was
replaced with two ribbon cables (one for each of those
ROM sockets), but whatever those two ribbon cables
plugged into is now missing. Therefore, the game isn't
working. :(

I'll try to post a pick, but does this ring a bell with
anyone?

BTW, I did Google thing and only came-up with one
reference to a conversion called "Hunchback", but some
of the info about that board doesn't seem to exactly
match mine.

Actually, dump everything and shoot it over to Widel so he can take up
some extra space on his new "Variety-PAC" (LOL *hint*)

A driving game would be a nice addition to the hardware.

That picture is Driving Force on a Pac-Man PCB.
I've got a Driving Force on Galaxian, and it's much simpler.
I gave a non-working PCB to Spaeth a long time ago...
did you ever bother to fix it?

Maybe we can get this on the 4-in-one Multi-galaxian!

As Mark pointed out, these CVS games are not Z80 based,
so you're not likely to see any of them on a multigame.
Getting someone to port this would be a tough sell....

All of the Century / CVS games run on signetics 2650 CPUs, not Z80s.

Complete code rewrites would be needed to make them play on anything.
(not to mention extensive hacking).

I've got a red CVS block floating around somewhere...
came off of a working Hunchback Olympics on a Track and Field PCB.
I'll offer it up for Free Friday! Any takers? Please....

Thanks for everyone whom posted about this. I believe
this is the board I have, albeit, minus the board that
the ribbon cables plug into. It looks like a decent
game, so too bad the CPU is all wrong for any
multi-kits. :(

Anyone interested in this, or should I just convert it
back, since I don't have the CVS daughterboard? I
don't have the Galaxian daughterboard either, but can
always do the hack to only require one or two PROMs
instead of the typical 4.

The ROM daughtercard for Driving Force on Galaxian
is pretty simple. I think it has four 2732's (or 2532's)
and a chip or two for address decoding. Maybe
Spaeth can take a look at the one I gave him and
tell you better. Might be able to do the single
EPROM hack and put all the program code in there.
