Making a non-ghetto adaptor
In the previous post, I discussed my odyssey to have an Apple IIgs with a good RGB experience. My solution involved a vintage RGB CRT that my parents had squirreled away that I subsequently shipped across the country. I had developed an adapter PCB and had it fabbed using OSH Park. Unfortunately, I messed up, and the holes were too small for one of the parts. I bodged it all together using jumper wires to make sure the circuit concept worked but I was not happy with the result. Recently, I did a revision of the board to fix the hole spacing and physical issues, and sent it off to OSH Park. Here is the old vs new design
It just arrived back from OSH Park and I fitted everything together, and low and behold it fit. Following the datasheet physical dimensions in the CAD program amazingly works better than randomly choosing a hole size. The following pictures show the soldered result, the adapter connected to the IIgs and my RGB monitor perched atop the IIgs. It looks pretty good, but I don’t think that is exactly safe (especially in earthquake prone southern California. I think I’ll build/find a platform so that the computer can sit underneath the monitor but not support the weight.
Overall this has worked out really well, and I’m pretty happy with the result. If I have time and inclination, I may use this project as a chance to design a custom enclosure for the PCB for 3D printing.
