The first short run of fully finished boards have been built and tested perfectly. I ran one in my HSII for several hours without a hitch - the others bench tested perfectly.





We have socketed the input chips which are really the only ones that can be damaged by problems on the playfield. The rest practically never give any trouble apart from battery damage.



We also laid the small clock crystal on its side and pinned it to the board to prevent damage and found a low case height 8mhz crystal for the other one.





All these boards were sold before we started assembling them but I hope to schedule a short run in the next week or so for those who are interested.
