8B backplane and 4K sram

I found a small issue in the layout of the 4K SRAM card. The trace leading from the ground past the fuse holders passes too close to the fuse holder for comfort. Since there is no solder mask on these boards, it would be best to mask this trace at this point with tape or something so it can’t inadvertently touch the fuse holder and short +5 to ground. Reviewing my layout, it looks like I missed aligning this trace correctly to the original layout. The layout in this area was obscured by the 10uF capacitor, and I didn’t notice the difference when comparing my layout to the original.

Ground Fuse Holder Issue

Next board to solder is the memory expansion board. It it will be fun putting in the 67 resistors that populate that board. Then I’ll have to cobble together a chassis for testing.
