Unread post by Xbytez »

The second episode is now available of Mister Retro Wolf's new series on youtube, perfect for getting you started with MiSTer FPGA arcade core development.

Episode 2:
Starting to look at the schematics of the Namco Tank Battalion arcade game, and looking at the timing circuit both on a breadboard and in Verilog. 3 chips are created in Verilog: 74LS74 D Flip-Flop, 74LS107 J-K Flip-Flop, 74LS161 4-Bit Counter

Xbytez - I'm honored that you'd be posting my videos to this site. Thank you!! I was going to do it myself by I see you've been me to it.

If there are any questions about the content please fire away.

The EP2 was actually getting to be close to an hour so I've split it into 2 parts. The now EP3 will be coming out pretty soon too, since it's almost done. In that one we will look at the timing circuit done.

The series is going to cover graphics rendering and then the good stuff of how the CPU and video circuit share the ram!

@nico24,
I hope you don't mind a quick question regarding Episode 2. Would you please let me know which book you used for the slides showing for instance the 74LS74? Please refer to the screenshot below.

I own all these 3 books:

Designing Video Game Hardware in Verilog
Digital Design and Computer Architecture
Introduction to Logic Circuits & Logic Design with Verilog

that you mentioned in the previous lesson, but I was not able to find that screenshot! It's just that I would like to follow the same resources :D

Thanks a lot!

That looks like a clip of the datasheet fort hat specific chip
Google "74LS74 datasheet" and you will find all the information about the chip.

Hope this helps

Yes - it's from the TTL book from Texas Instruments.
You can get it from this link:

Just a quick point - the TI book has the pinout and logic 'truth table' on different pages - by the magic of video they are together, so don't go looking for a page with both on, because you won't find it! Most other datasheets have both together though.

Super, thanks for confirming! That Logic Pocket Data Book is within my library now!

Thank you for this, I’ve been following it and it makes sense, and I can see it becoming a time sink for me.

I’m an old sod professional .net dev who always envied not working on hardware instead, and this has started me scratching that itch. Please do keep it up. Gaming has been a passion since the 80s and I’m loving this.

MysteryM10 - thanks. Yes - we'll have Episode 4 coming in the next day or two - it's getting a video picture on the screen.
