Apple II

I've been picking at this for a few weeks, thought I would share the progress.

I was able to find an early Apple II Rev. 0 board a few months back, (replica I assume) and thought I would build up the board.  I used vintage gold pin Augat sockets instead of the Robinson-Nugent sockets Apple used back in the day.  I'm partial to Augats, as I've been using them for decades and they've proven to be quite reliable over time.

I've posted a link to the front & back of the finished board Here: (files are a bit too big to U/L here...)

Hi, new to this forum and hope some of you guys could help me. I assume ill need to try and supply more information so please let me know any other details.

Basically I managed to dig my old Apple ii Euro out of the loft and before powering on had the power supply recapped. Output has been tested since and are near correct voltages.

I have today put the PSU back into the unit and powered on. The card in slot 7 is a PAL Modulator and when powered on the led on the slot 7 digitek card powers on.

My Apple Color 100 works well, but the brightness pot seems to be faulty. The image is stable, but only at max brightness. Once I adjust the brightness down a bit it flickers and wavers a bit, then fades totally to black. If I fiddle with the knob I can get it back again, but it often is very finicky.

I welcome any thoughts on this. I haven't cracked it open yet -- it looks tricky to open, what with tabs and catches as well as the usual assortment of screws. I wonder, would that pot be a standard item?

It's a very nice and clean specimen so whatever I do, I want it to look good and work well. Should I use epoxy? It seems to me that normal superglue wouldn't be strong enough. Any advice is appreciated.
