Not DOS, but I sold a '99 HP computer running win98 last month, to replace an identical failed system. It was used to control a 50 meters long custom industrial paint booth line for special equipments (like 57" rims). Luckily, their HDD was OK. Urged them to make a few sector-to-sector copies of it on a few spare HDD. This $100 sell surely has prevented this business from massive bills or even going bankrupt in the meantime from production loss.
Insane to me that someone would use a windows machine to run a piece of equipment when PLCs exist and are supported for decades by companies like Rockwell, Siemens, Allen Bradley
There are lot of windows based solutions since more than 20 years ago for two main reasons : recipe management system, and logging. A basic SCADA of sort. PLCs systems of that era could either not manage it (TSX, S5,S7-100/200), or it would be additionnal very expensive, complex and typically OPC-based solutions (I'm shivering).
Some of theses solutions are built upon common PLCs but some are built as standalone solutions when I/O are simple enough (modbus mainly, RS232/422/485, ethernet/IP, controlnet, ...). Seen lot of them in breeding nutrition management systems, in-house developped processes, ...
Think that’d be worth more than 100 :)
I had it listed at this price for a few months, simeone from their company purchased it and rode 2 hours and half to come get it. Couldn't and had no reason to up the price at this stage. Indeed, this was a very good deal for them.
