In this video I quickly review the Process of programming an Altera MAX7000S Complex Programmable Logic Device (CPLD) form the 90's 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 that's in JTAG LOCKOUT ? [#61]
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 90's and early 2000's.

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 CPLD's from the 90's, JTAG programming as well as other parallel programming systems that were capable of programming Altera logic devices. Fun Stuff!
