I had use of a IBM clone i286 12MHz(i8086*2) it had a 20MB hard disk and the new EGA colour screen a 1.2k modem (frequent use). Estimated over 30,000 amateur bulliten boards.
It belonged to my father a Viglen.
There were only a few PC programs available all Ms-Dos based. Word Perfect, Wordstar etc. (word-processing) Lotus 123 for accounts (basic spreadsheet - the 1st one) and mainly Dbase for databasing. A few games (shareware / public domain) no soundcards.
Windows as we know it arrived in 1990.
