80’s and 90’s and yeah. pretty much my word on it. If I was like dragged into court I could likely get some records suponed and maybe prove some of it. Heck even after that I worked for a contract engineering firm that did y2k remediation. Its on my resume way in the back (I utilized a multipage format where the first page could stand on its own) and on linkedin. It got bought out after I worked there and I think then eventually was closed up. My guess is they may have been bought for the software. I could drive to the buisiness park and maybe even identify the building where I used to go work but its not that place anymore and I don’t think I could get any evidence at all that I worked there and im like pretty sure I can not even prove it ever existed but maybe. Its like the first job in my tech career.
