Slight error.  The first eBay item hasn't expired yet.
<https://www.ebay.com/itm/365192218756>

Here's some history on PCR Thermal Cyclers:
<https://www.thermofisher.com/us/en/home/life-science/cloning/cloning-learning-center/invitrogen-school-of-molecular-biology/pcr-education/pcr-thermal-cyclers.html>
Congratulations.  It seems that you worked on the very first one. The
TC1 DNA Thermal Cycler from Perkin Elmer Cetus in 1988.

Despite the description from your resume entry for 1988 claiming that
you did "Total hardware design and software re-design of
micro-titration instrument", the details are all about writing
firmware and software for the device. "Developed firmware for
Pro/Group blood typing for customers".
