I started out knowing nothing about electronics. Bought a Electronics Learning Lab from Radio Shack and Bam! It became my daily hobby and career path of choice. Although I am still in school I continue to try and compare modern day technology to older tech to learn how it works at its core.

That's very impressive! I have been attempting to use the 8251 UART but was having issues getting it to work. Do you have your actual assembly code anywhere? I would like to see how you initialized it, sent, and read data from it! Thank you for your comment I would like to see more!
Yes it should be in this case. Just a word of warning though, do to a limitation on the current the z80 can supply I would not recommend this in larger builds. I have been working on updated models which include buffers between the two chips to allow for better signals. Some sort of Tri-state buffer can also be very helpful when adding I/O, etc.
