![How to Connect & Program multiple Altera CPLD Logic Chips on a single JTAG interface? #90sTech [#62]](https://i.ytimg.com/vi/nZ4tEelDR5g/mqdefault.jpg "How to Connect & Program multiple Altera CPLD Logic Chips on a single JTAG interface? #90sTech [#62]
In this video I quickly review the Process of programming an Altera MAX7000S Complex Programmable Logic Device (CPLD) form the 90s using an Altera JTAG programming Pod called the USB-Blaster.
You can see this process more in depth by watching my previous video Below:
How to Program an Altera CPLD Logic Chip From 1998 thats in JTAG LOCKOUT ? [#61]
https://youtu.be/0WAaH37rmEk?si=m1rzq7fxxde9NQPV
I then do a quick Show-N-Tell on some of the older Altera JTAG programming PODs that were released in the 90s and early 2000s.
I finish off the video demonstrating how you can connect and detect multiple Logic devices that are sharing a JTAG programming interface and can be used to Program multiple devices in a circuit. This programming bus is referred to as a JTAG chain.
A JTAG chain is a series of JTAG-compliant devices connected in a daisy-chain configuration, allowing them to be programmed, configured, or tested using a single JTAG port.
Expect to see more videos on Altera CPLDs from the 90s, JTAG programming as well as other parallel programming systems that were capable of programming Altera logic devices. Fun Stuff!

NOTE: This Video was re-uploaded due to a re-edit.
PART#3 of my ongoing N64 programming PRIMER series.
In this video tutorial we are covering the SPECFILE.
In this series I will share N64 development tips as well as my Homebrew code. I will also review various N64 Demos from the SDK, and will try and explain how the N64 code works line by line, and go through the flow of code from console startup.
In this video PART#3 we review the SPECFILE used as part of the many N64 SDK DEMOs and any homebrew code that you will be creating. This is an important file that is required as part of the ROM compile process.
If you need some help installing the N64 SDK and Libraries onto your Windows PC, there is a Video on YouTube you can watch that will guide you through this process....but read this note below first:
NOTE: Use this disk image link posted below instead of the one in the video. Reason to use this one is because it includes all the updated bells and whistles like demos and other assets. So special Thanks to the Folks over at N64Brew Discord channel for putting this image together:

I have teamed up with Tony from the YouTube Channel Hard4Games to cover this fantastic Nintendo Gameboy Development Unit known as the IS-AGB-EMULATOR by Intelligent Systems. ( Game development kit )
Tony will be covering the Emulator Software for loading CGB/AGB games and he will also Demo this Emulator unit connecting to a Wideboy64 for the Nintrendo64 console!! Tony is also showcasing a unique and Rare Gameboy Advanced Prototype Handheld supplied by @GamingLegend64 (Twitter). So definitely check out Tonys video on this unit!! (Posted on Sep/25/2021)

![How to use a Quadrature Rotary Encoder with an Altera MAX CPLD?…& Jurassic Park? [#66]](https://i.ytimg.com/vi/rHK6jUrP6DA/mqdefault.jpg "How to use a Quadrature Rotary Encoder with an Altera MAX CPLD?…& Jurassic Park? [#66]
In this video I show you how to interface a Quadrature Rotary Encoder to an Altera MAX EPM7128SLC84 CPLD logic device from 1998. We implement a Quadrature decoder circuit within the CPLD using the Graphical design entry form. Once the circuit is built, we perform a practical test on an Altera PLDT-2 development board and read the logic pulses generated by two separate rotary encoders. We then display the counted pulses on a dual 7-segment display housed on the dev board.
Now I intentionally changed my circuit slightly in Quartus compared to the practical demo. This change would alter the displayed maximum number. Can you spot what I changed? Hehe! A Fantastic interfacing project. :)D
I also talk about a Digital apparatus that was built for the film Jurassic Park in the early 90s by members of ILM, Tippett Studios and Pixar. This device was called the D.I.D. or Dinosaur Input Device. This was a puppet motion capture system, and it used the same type of Quadrature rotary encoders as we were testing in this video. (Bourns Rotary encoders)
https://www.bourns.com/docs/Product-Datasheets/ENC1J.pdf
The electronics and computer interface for the D.I.D. was built by Craig Hayes of Tippett Studios. You can read an amazing in depth article on the Dinosaur Input Device at the link below:

![Connecting my N64 Console to an FPGA over the Joystick Port [#6]](https://i.ytimg.com/vi/rKU0B4scPDM/mqdefault.jpg "Connecting my N64 Console to an FPGA over the Joystick Port [#6]
NOTE: This Video was re-uploaded due to a re-edit.
In this Video, I explain and give a demo on an N64 interfacing project which I worked on many years ago.
I wrote some FPGA code in VHDL that receives the serial signals from an N64 console, from one of the Joystick ports. (Port#4 for my Project) It then translates this N64 Serial protocol into ASCII Hex Data. The data can then be sent to an LCD display, or potentially to an RS-232 computer Serial Port, and displayed on an MS-DOS Hyper-terminal session using a program like PUTTY.
I also programmed a custom N64 ROM that runs on an N64 Flashcart to drive the serial signals I want, out to the serial Joystick ports. (AKA JOYBUS ports). This is implemented using DMA transfers to load HEX data into ram, and then writing directly to the N64 PIF chip registers. This allows us to Send/Receive signals to and from the N64 Joystick ports.
I hope you all can enjoy this old N64 interfacing project of mine. This was loads of fun.

![Sega Genesis Development Flash cartridge REV D by Western Technologies - Game DevKit [#29]](https://i.ytimg.com/vi/sZF-Q0_HCXU/mqdefault.jpg "Sega Genesis Development Flash cartridge REV D by Western Technologies - Game DevKit [#29]
In this video I provide a Full in-depth hardware and software DEMO of a 32Mbit Sega Genesis/Mega Drive development Card REV D released by the company Western Technologies Inc. In 1993. I go over a Simple ROM loader program, as well as a Software Debugger. I then review some Sega Genesis source code for a simple Hello World demo program and go over the compiling process using the SIERRA C cross-compiler using a DOS batchfile.
This development cartridge allowed developers to load Sega ROMS under development into the SRAM memory of the cartridge, using an LPT Parallel Printer cable connected to an IBM PC compatible computer.
A simple DOS based command line tool was provided to load ROM files directly from the Development PC. The unit also came with a Full blown SEGA branded 68K software Debugger, which also ran under MS-DOS. It provided a Disassembly window, memory Dump to view HEX data, as well as a Register view section. You could even set Breakpoints and access specialized VDP Register and RAM memory controls.
This unit was quite sophisticated for its time, and is for sure a fantastic development tool for developers and Hobbyists writing their own Homebrew.
This is definitely a Rare and unique item that is highly sought after by collectors.
Hope you all enjoyed this Hardware Demo Folks!
Cheers!

(A Gameboy Advance XBC -XPORT custom cartridge for robotics Botball competitions & a Super Nintendo Gateway game controller.)
I also talk about an upcoming video series I plan on posting here on my channel for all of the Nintendo 3DS related development hardware I have acquired...and my plans to demo both the hardware and software.
Lastly I talk about a very interesting device called a Dinosaur Input Device or D.I.D. This device was custom made by the company ILM for the film Jurassic Park back in the early 90s. I talk about the hardware and plans to build a very simplified version of this device to demo here on my channel.
