content: This could be an interesting project. At the moment, I have watched only the first video in the series.The author's choice of System Verilog instead of my preferred VHDL is a two edged thing. First, I don't know anything about Verilog or System Verilog but, second, I might as well learn System Verilog because there is a lot of interest in the language.The design choice to use microcode is interesting. I like microcode and I go back a long way with that approach although lately I have just been using a gigantic FSM. I look forward to seeing how this works out! Remember, IBM invented the 8" floppy to contain the microcode for the System 360. We've come a long way but it's good to look back and see just how far.I think I'll follow along with this project and see how it works out.https://www.computerhistory.org/storageengine/floppy-disk-loads-mainframe-computer-data/ETA: Working through the playlist, I don't see episode 7 and onward. As of episode 6, a lot of the hardware is working but it is far from a complete project.

content: Now that we have zynq and ultrascale technology, implementing a microcontroller is an academic exercise, yet a lot to learn.I remember implementing a simple DSP for digital audio many years ago. It was fun. I remember using XILINX IP to insert a logic analyzer into the FPGA design. That helped a lot. Later i read there were HP scopes that could show the trace memory on screen. Don't remember the details though.Regards, Dieter

content: Quote from: asmi on November 15, 2021, 09:11:20 pmIt must be very recent because I went looking for it. Noting that Part 6 was very old (12/31/2016), I thought maybe the series was finished.I look forward to Part 7..ETA: At my age, patience is hard to come by.

content: Quote from: dietert1 on November 15, 2021, 10:20:12 pmBut what if we want a hardware based emulation of an existing machine that runs all of the factory software unchanged? Like the famous 27 pass FORTRAN compiler.There is a software emulation based on simh but that isn't hardware. If you spent your entire college education on digital design, software solutions don't count.http://ibm1130.org/

content: Quote from: rstofer on November 16, 2021, 12:49:15 amAre we both looking at the same channel? I see the first video came out 11 months ago, not 5 years. See attachment.Quote from: rstofer on November 16, 2021, 12:49:15 amIt's already out.

content: Just looked at Part 7 and didn't like it. Don't know why someone adds 74LS.. gates to a circuit with a Spartan 3 FPGA. FPGAs are made to avoid that and instead contain all the glue needed. They usually have enough pins to blink some LEDs.Regards, Dieter

content: Quote from: dietert1 on November 16, 2021, 10:28:16 pmI went to Robert's YouTube channel and selected the playlist. I only see Parts 1..6. I searched the web and still can't come up with Part 7 for this project. There is a Part 7 for the 6800 project but I'll be darned if I can find anything about the Zork project.Have you got a link?ETA: You're right, different project. I was after the Zork project because it is Zork and has some historical cred. Just another CPU isn't interesting (to me), I've done a couple of those. I was looking forward to a microcoded project.
