I have not built it on any board. The IC and all components are inside the 23 Pin DSUB housing. And it takes quite a deal of effort to wire that correctly and isolate it with shrink wrap hose, prevent interference from the IC etc. That said. It can easily be built on a PCB, though it is almost not necessary.

The IC gets power of the 23Pin DSUB (pin 23 is 5V). You could tap into the power from the GBS 8220 as well, if you like. It is not exactly as if hte 74HCT14 are using that much current. The biggest issue is avoiding switching noise from the IC..

The GBS 8220 I run from the same ATX power supply that I use to power my A1200.
