Pincoder Diagnostics Inc. Version 2020.02.10.1842
RELEASE VERSION NOTES
==============================================================================================
Changes since the previous Release version:
* Slowed pulse rate (PIA1 Pin 4 – PA2) on 02-blanking from 2500Hz down to 120Hz to match
williams ROMs refresh rate.
* Eliminated ghosting from neighboring segments on displays.
* Added 11b-sounds test to allow sound card testing on the bench.
* Modified 10-solenoids to also fire a solenoid using the DIP_01 switch together with the
COMMAND ENTER button on the MPU board. Some games do not have a HIGH SCORE RESET button.
* Temporarily removed sys7/2K images.
* Rewrote the documentation for “01b-bus”. The ROM itself remains unchanged.
NOTE: Hyperball is not fully supported in this version. Specifically, the displays
ROM does not test the alphanumeric display in the playfield. However, I now have a
working hyperball board set and will release an update in the future that contains full
support for this machine. Hint: The sound test ROMS have already been verified to work in
Hyperball. I have not yet verified any other test ROMS in Hyperball.
