when i was working Most PC Machines were some version of the Epson Equity line (I, II, III), and Custom Built version called WINN. Unlike the Epson Machines that were exactly alike in a version line (there were differences between I version, II version, or III version), using exactly the same Floppy Drives, Hard Drives, Power Supplies, Etc.; the only thing common about the WIIN boxes were the outside case. Everything was different, logic boards, video cards, Hard Drives, Floppy Drives, CD-ROM drives (for those with them). The Epson Equity I line used MS-DOS 2.x, the II line used MS-DOS 3.1.x, the III line uses 3.3.x I don't remember using | but I do remember using the \ and /'s I retired the summer after the first version of W-95 came out. We mostly used Windows 3.1.1. at the four high schools were the only ones allowed to try W-95. Am I remembering wrong but didn't the very first version of W-95 actually come out in 93 or 94? I am asking not stating as fact. so don't get wound up if I am wrong. Anyway it gives you an idea of how long since I have looked at DOS. I used On-Track software to setup and initialize new Hard drives when I had to replace Hard drives. Everyone was using a utility called something like Drive Space or Double Space that would let you hold 40megs of info on a 20 meg hard drive. Using this utility though at the time, the hard drives tended to fail in a short period of time and need replacing. I was replacing Floppy or Hard drives in DOS/Windows machines about every two to three weeks. On the Mac we had SE's mostly. I replaced on Hard drive and one power Supply. Until we started using the LC line (pizzabox machines). Then we had a run on any using Maxtor Hard drives. If Quantum Drives were used, no problems. -- --------------------------------------------------------------------------- Phillip M.
