The BLACK HOLE (model #668) Pinball that we own has been improved and has now new functions. The main amendment carried out is the SYSTEM 80A translation, with replacement PROM U2 and U3 by a new single EEPROM and the rewiring of the displays.
Features of our Black Hole:
- Talking US version with animated backglass.
- Display on 7 digits.
- Legacy of improvements of the SYSTEM 80A:
- Quickstart (equivalent to the FASTBOOT).
- Improved test mode & bookeeping.
- New configuration of the DIP (moneyers...).
- Limitation of the high-scores (overflow protection).
- Deleting of the service printer.
Black Hole modified CPU board:
This photo is the first version where you can observe an additional wire cable to the EPROM (on U3). A new version with EEPROM (on U2) replace it, on which this wire was removed.
New CPU board for Black Hole:
For a long time the rumour ran on the existence of a Black Hole in 7 digits. This is not a myth, the flipper has indeed existed!
A prototype designed to test the new SYSTEM 80A was directed, and in principle, never should have left the workshops. Except that, this unique model has been one day delivered by error in France...
Unfortunately, later, during troubleshooting, this Pinball was recovered by the manufacturer and handed over to the standard SYSTEM 80. His owner did not have the time to copy the PROM before, thought that this version was permanently lost.
One of the peculiarities of this pinball machine was to be equipped with unconventional 7 digits tubes. These first models had rounded shapes while those used later on the 80A series will be much more angular.
Reconstruction and portage in SYSTEM 80A
We decided to rebuild this prototype from a US Black Hole, changing the wiring of the displays and creating a new game PROM adapted to the SYSTEM 80A.
In the end, our model works even better than the original. Indeed, the portage to SYSTEM 80A allowed us to discover some defects very certainly suffered by the prototype:
- Attract mode is different and not the best effect.
- Inter ball animation doesn't works (brief high-score display).
The first is a change made by the SYSTEM 80A. While in SYSTEM 80 the attract mode is a simple chase on 5 lamps, from the SYSTEM 80A is much more random. The second is due to a bug in the 7 digits display that does no more allow to toggle the display to high-scores when a party is in progress. This animation was most likely removed on the prototype.
On our Black Hole, these two defects are corrected. The initial attract mode thus inter ball animation are put back in place.
During attract mode, the erratic movements of the wireform ball gate (located in the outlet of the tube) has also been removed.
Improvement of the bonus
The display and operation of bonus suffer from several shortcomings on the orignal Black-Hole. Even if they do not notice at first glance, it can be seen that:
- The permanent display of the bonus, even when it is zero, is not very aesthetic.
- During the countdown, useless zeros are added to the display.
- This countdown is not progressive (for example, 10000 points are counted faster than 9990 points).
We have therefore improved functioning and corrected these defects.

Function "Right Flipper Rotate"
We have added in the game PROM, a feature that allows to scroll up through the right flipper button, the three top corridors. Like that which exists for the Mars God of War, simply add a switch in parallel on the right flipper EOS contact and link it on the SW36. If it does not wish to use this feature, simply do not connect this contact.
This achievement is available on demand, contact us for more informations.
This version SYSTEM 80A of BLACK HOLE only works with our unique PROM adapter.
