Star Hawk problems: solved

Hi All,

My star hawk now works.

LF13331 works fine, but probably I'll bought a couple of spare chips from
arcadechips, thanks to all of you offered me a replacement. This night i'll
try to mount a DG201 upside down just to see how it works

I started from this condition:

First of all I replaced original ROMS with a couple of 2716

a couple of wires are enough to adapt 2716 pinout to 9316's

then, following the block diagram, I began to test the "line len." Block and
I could immediately see that one of 74193 had been replaced in the past.
Removing it I found some broken circuit tracks, so with an easy fix now I
can see this:

Everything now works. I'll post cabinet pictures once restoration is
finished (just a couple of wires to the coin door and a small part of
t-moulding to replace)

To say the truth i'm using a vectorbeam PCB because the original
cinematronics is dead, but i'm waiting for a not working speed freak:-) so
soon i'll repair the original pcb

If some of you has a couple of original 9316 star hawk roms write me :D

Thank you for your help,

vernimark
