 @96d079fd @16340ea3 Looks like your total RAM is also showing as 128KB just like mine. What type of RAM are you using? Can you share a photo of the board?

 @8ff2c4ef @16340ea3 Sure, here's a photo of the board with the 80ns NMBS marked RAM, and 120ns Samsung (just two modules of the set shown).

 @96d079fd @16340ea3 Thanks! I have those NMBS modules as well and so far they are the only thing that’s close to working. I have two other sets (OKI and Fairchild) that don’t seem to work.

 @8ff2c4ef @16340ea3 I looked through my notes and NMBS is what VintageMicros provided in the kit. The Samsung modules I picked up later hoping it was a RAM issue.

 @8ff2c4ef @16340ea3 I'm not sure how useful this is, but here's a photo of a Rev "A" SunRem board I saw on eBay a while ago - a little different layout.
