New batch SCELBI FP, CPU, DBB & Input PCBs on order

I finally sold my 19th set of SCELBI boards. There were 20 sets made in the original batch for the 8H that were made in January of 2013. There were about an even number of 8H and 8B sets sold, and the boards I’m reordering are common between the sets, as I still have plenty of the boards that are unique to each system. There are only two differences between these new boards and the original set of boards.

1) The size of the holes for the zener diodes is being made a little bigger. Note that if you can find them, the leads for the original style zeners in the cans will fit in the original holes, but more modern zeners have thicker leads may not. Older boards will work fine with the more modern zeners, but the holes will have to be reamed out a bit and the leads soldered on both sides of the PCB.

2) This time around, I’m adding a silkscreened legend on the front panel board. The original SCELBI front panel boards came both with and without the legend, but I see more original units with the legend. This is why I’m adding the legend to this batch. When I made the first set, I thought that only early boards that were made before the advent of the aluminum front bezel had the legend. Later on, I discovered that a number of systems with the front bezel, also had a front panel board with a legend silk-screened onto it.
