George Haswell, Mayor of Circleville at that time, was also Superintendent of the Water Works & had an office on West Main Street. He decided that it would be a great idea to try to get the country folks and city folks together so he invited the country folks to bring the best of their produce to town on the designated dates & display them on the streets of Circleville so that the city folks would be able to appreciate their efforts.
In the early days there were 3 boards CPU, IO, and Driver. The CPU board used the Motorola MC68332 processor. The driver board was set up to be used to spray or spark in arbitrary combinations, and this board is still in use in the current configuration. The IO board on the other hand was complex and suffered from periodic loss of TPU/crank wheel sync leading to the development of the current configuration. At this point list members Bruce Bowling and Al Grippo decided to combine the IO and CPU board functions to reduce the susceptibility to noise. At some expense, new sketches were made, with increased attention to routing and details, and the result was a new board called the 4-layer, This board is the basis of the current configuration and incorporates separate power and ground layers to aid in handling EMI. Details of the boards: CPU – MC68332 @ 20Mhz + 256K static ram + 256K flash rom + 1 serial port + BDM connector + connectors for IO & driver boards + expansion connector. IO – A
