@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.
@96d079fd @16340ea3 Good to know, thanks!
@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. https://files.mastodon.social/media_attachments/files/111/135/679/236/105/994/original/164286e51335cd00.jpg
