Me too...I was putting that on my list of projects for the new
year...would like it so I can test the Bally sound boards. Some can be a
real pain...<br><br>
<b><u>New Years Projects<br><br>
</u></b>Perhaps a group effort on projects that are important to folks.
Seems to me we need a few routines: PIA's - 6821, 8255. RAM - 5101 (256 X
4),&nbsp; Sound generators - 76541 (whatever -the Space Invaders etc.
one), AY-3-89XX series... make them as scripts that you fill in the
blanks.<br><br>
I ran out of steam on the compression of the PDFs as it coincided with
some business crises (Xmas etc.)...but those are past (I hope)...and will
take it up with the volunteers in the next few weeks if they are still
free.<br><br>
Still trying to crack the FLUKE ROM Signature...any volunteers there?
This would be of greater use than the compression I believe as we could
then talk someone into making a small program that will generate the
FLUKE ROM Signature for ROM images in files for easier
verification...<br><br>
