Can anyone identify these 2 boards?
http://members.rogers.com/lewinsky0857/unident/
The first one is a two board set with 4 LED's in the center of the board. I
can't power up this board as it is missing 1 EPROM and won't boot. It has No
unique numbers or markings on it either. So Im hoping someone can recognize
it.

The last board I am guessing it is a pinball board of some type. It is a
Williams product. it has the # 5770-12204-00 etched on the component side.
And a sticker with "C-11879-3036"

Well I don't think it is Defence Command. If you look at the board there are
6 EPROMS( "A" to "F") 2732 + the one missing in that row so I figure it is
a 2532 as well ("G"). And there is the one Eprom by itself marked ("H") and
its a 2515. So this totals 8 EPROMS in total. The ROM set I downloaded for
Defence command has 10 eproms + a sound eprom file. so thats 11. So It
doesnt look right.
Bootleg Defender aka Defense Command.
Check Google for pinouts etc which I put on RGVAC
a few years ago ...

Joe Magiera and I archived the ROMS and reverse engineered
the pinout for Defense Command sometime ago. Perhaps
he still has them as I've "misplaced" my copies. :-(

So now you know there seems to be several bootleg versions
of Defender out there - slightly different boards, different ROM count
etc.

SPW
Yes that appears to be it, but. Any of the EPROM sets I have found for
download for "defense Command" have not had anything close to the proper
ROMS in it. So then I guess the question is, Does anyone have the proper
bootleg Defender ROM set available?
P.S. Thanks for your terrific tracking skills guys!

Well If you can drop him a note to see if he does I certainly would
appreciate it. I will post around also and keep looking for them as well.
Thanks for your help!

The top one looks like a bootleg Defender. I had a few like this that were
"Defense Command".
