- bedobi 2y agoactually, I do :) is it DOS? some IBM mainframe OS? do tell
- Wytwwww 2y agoWas DOS actually every used on mainframes/servers on a significant scale? (genuine question, not saying it wasn't)
- wrs 2y agoA mainframe OS called DOS was in fact quite popular, but it’s not the same thing as the DOS that was in PCs. (There were others, too, like Apple ][ DOS. As soon as your computer gets the capability of attaching a disk drive, somebody has to write a Disk Operating System.)
- kayodelycaon 2y agoI do actually. My last job had a mainframe team maintaining (and adding to) an AS/400 application. They still had punchcard programs. They had json apis. Each one had some variation on parsing http from a raw tcp connection with IBM RPG. I had to do some unspeakable things to a ruby library so I could control the order of the headers.
- fourteenfour 2y agoLooks like it was IBM System/360 mainframes but they've recently migrated to google hosted services.
