Jul 23, 2019 at 3:52 comment added Chris Stratton Perhaps it's taught you how to engineer small computers and design PCBs in the 1980's, but things work differently now. Modern architectures are very different (even MCUs have ideas from the mainframes of that era), the software schemes and languages they are intended for are different, and both physical and logical aspects of board design for fast surface mount parts with serial interfaces are quite different than for slow DIP ones with parallel busses.
Jul 23, 2019 at 3:45 comment added jacobtohahn @ChrisStratton well, a lot of it stemmed from my interest in vintage computing, so I wanted to better know these computers by working with the chips they used. Another aspect was PCB design. Whatever it is, this project has taught me more about computer engineering than nearly ever other project I've done.

Jul 23, 2019 at 1:55 comment added Chris Stratton A desire to learn about architecture is all the more reason to use something like an FPGA; otherwise you're stuck with the limitations of available old parts, rather than being free to concentrate on sensible architecture. Anyway, part selection questions are off-topic.

Jul 23, 2019 at 1:52 comment added jacobtohahn @ChrisStratton thanks for the response. I'll check out the 8251. My goal here is to create a system using as many "original" chips as possible, hence why I chose the DART. I definitely don't want to make the system on an FPGA, because this project is mainly to teach myself about system architecture, but I may eventually to learn how to use an FPGA.
Jul 23, 2019 at 1:44 comment added Chris Stratton This type of question is off-topic here, but another from that era was the 8251. Don't rule out using something like a modern MCU as a supervisor providing this and other functions; for that matter consider building the whole system in an FPGA.
