I've redisovered one of my oldest computer in my brother's basement storage this week, a 25 years old Amstrad PPC640 - it still boot up to MS-DOS 3.1 and use 3.5" FDD. With a 9" mono screen, it's heavy but graphics wasn't too bad hooked up to a 13" RGB amber monitor - used it for Lotus 1-2-3, Words and Condor 3 to manage membership & donor mailing lists (before dBase 3.) It was a decent setup then to access BBS and to log into Eassy Sabre (pre-Travelocity) then to do bookings and to access OAG online,modem was ok @ 2,400 bps in those days. GEnie online access was cheap and never part of the AOL generation.
The heavier tasks were done on networked Altos terminals as mainframes & were king in those days (mid 1980's) - finances were done on the IBM 370's into the mid 1990's. Anyone else remember those 11" disks used for the Wangwriter systems - some of my earliest government grants were written & saved on those diskettes, kept one for memories & another one has the resume from 1981 ...

the old days.
