Version 2.3 of the PCB has arrived, been assembled and tested … and it works without any wire patches!
There is, however, one minor problem. I added some extra bits of screen print on the wrong side. This has now been fixed on the gerbers and any future boards will be correct, but I am not changing the version number for that minor problem. (there are only 10 PCBs that have this defect, so should not cause any problems in the long run)
On the sound filter section of the PCB, the second capacitors are tantalum, which means they have polarity so there should be a small + sign to show which way they are fitted.
Check out the Bally Astrocade interface pages on the menu under “Mister” for more details of the board and assembly.
