    bro i need more of it, I truly enjoy learning this stuff, I love learning about computers hardware, thanks,

    This is _fabulous,_ Dave. I was so pleased for you when it worked! Wonderful! 👏 (And thanks _again_ for doing this without the music! 👍🙏)

      Thanks! I was definitely surprised that resolving the glitches was as simple as using 74ALS counters rather than 74ACT. For good measure I'm also going to replace the 74ACT157 mux with a 74ALS157 and the 74ACT273 chips in the row begin address register with 74ALS273. I think 74ALS is my new second-favorite logic family (after 74HCT, if course.)

      Yeah, @@davehohacks, it was beautiful to see it working so well. By the way, I remember during your first attempt with the FPGA you concluded that you didn't know enough. I don't know whether you've come across him yet (and you may already be ahead of this), but John's Basement has a great series on FPGAs, using the ICE40's: th-cam.com/video/TJbI-NMJaUY/w-d-xo.html&pp=iAQB … I was going to go straight to FPGA, but you've inspired me to try the TTL route first. 👍

      @@rogerramjet8395 I'm actually excited to pick up FPGAs again after doing this project with GALs and discrete logic. Thanks for the video recommendation, I think it will help a lot to absorb some proper background knowledge.

    Nice work. Thnak you for this build with clear explanation what/how/why! BTW: what wire do you use for your prototyping? Your results are so neat...

      If you search AliExpress for the term "UL1423", there's a listing from a vendor called "FreeBoom". I'm using the 26 AWG version. It's like 30 AWG wire wrap wire, but a little bit thicker.
