[ukvac] TECH : Mr Do missing chip
I am missing a single socketed chip on an original Mr.Do board at J2, it
is marked with PAL16R6CN, and overstamped with U001 [ on the schematics
parts list it is listed as U001 - special functions chip ]. If I swap in
a known good chip from another Mr. Do board, then the board works fine.
Is there a substitute that I can get for this chip or will I just have to
rip one off from a dead Mr. Do ?
Ta for any help

At a guess

And this is a guess I'm sure somebody will flame me...

You might be able to use the bootleg roms.... as the bootleg board I've seen
have the space on the board left empty without even a socket... so I assume
the software has been modified or maybe a few mods to the pcb?

Regards

Daz

I'm sure somebody else will correct me if I'm wrong

basically, all that should happen is you get crap in the background as
without the custom chip it doesn't clear the screen. If I remember correctly
from the one we did ages ago you only need one program rom from the bootleg
set.

And indeed it is only a single modified byte in that rom.

Now this is going to be really dumb! I flogged all my faulty Mr Do PCBS
a few weeks back so I no longer have the ability to dump that rom for
anyone - DOH!

standard mame issue

if you *really* can't find it, mail me and I'll send it to you

I can even write it to a 2764 for a nominal fee

in fact, I could even sell you a mr do PCB - now there's service for you!
