Bytek S125 Eprom Prom Gang Programmer Teardown
This is the Bytek S125 Programmer from the mid to late 1980’s.
A Few of the buttons have Broken off been floating around here for decades! I lost the diskettes that had the software I was unable to locate a copy online. I was able to find a sales advertisement from byte magazine April 1987
I am Doing a Quick Tear down To Document It For Historical Value.

Re Assemble! Place in E-waste Bin.
This will be on the next e-waste scrap run unless someone wants it? You may contact me and if you pay the shipping costs it is yours. Maybe you will have better luck finding the software for it or use it for parts for a broken one.
Thank you rsjsouza on the eevblog.com forums he is the new owner of this vintage hardware.
