My JTAG Technologies "JT-37x7/TSI" Boundary-Scan Controller and its
Quad-POD Interface model "JT-2148".
The JT-37x/TSI Datablaster controller is available with 1 of 3 different onboard Flash memory modules.
These modules are installed during manufacturing and you simply designate which module you require before purchase.
You may request a 32M-Bit (JT-3707), 64M-Bit (JT-3717) or 128-M-Bit (JT-3727) module for on-board flash image memory.
Once installed, a manufacturing sticker is placed on the bottom of the Controller enclosure, designating which memory module is installed.
ThisThis type of controller can be used for performing Boundary scan Testing and also JTAG ISP programming. Components can be interfaced directly or as part of a JTAG Chain where multiple components are connected in a series Daisy-Chain as shown in the image below:
You can use the Free JTAG Technologies software
"JTAG-Live" and also the $125 package "JTAG=Live+Plus" which supports added features.
