I would add the Honeywell 316/516 series to the list. The 316 was the first 16-bit minicomputer, still using DTL logic. The 516 used TTL and served as the IMP 'router' in the early ARPANET. They were fairly popular before the PDP-11 took over with its brillant architecture.
Excellent point! I provided a little more detail on the 316 and 516 in my comment yesterday, https://news.ycombinator.com/item?id=43125358.
