I bought my first computer circa 1985 from Sam's for $1800. It had a hard drive, which was a big thing at the time, and two floppy drives, and a green and black monitor. It was better than the one I used at work, I think it had 256 MEGs of RAM. Back then, DOS would only handle 640 maxed out, if that.
I used a program called Symphony, which was an enhanced version of Lotus 1-2-3. It had word processing and communications on it.
That was a lot of money in 1985. Might have been more like 1988, I think we were in the new house (1987).
The nerd is me feels compelled to mention that your computer probably had 256 Kb, rather than Mb, of RAM. DOS could only do 640kb at a time. There were several reasons for this, chief among them being that no one would EVER need more memory than that!
Later implementations would still have this limitation, but would mitigate it by creating 640kb "pages" of memory - then using a manager to flip between them.
At the time, everyone used to reference the Library of Congress as their standard. A 40Mb hard drive could "store all the books in the Library of Congress" - like someone was going to do that, or understood what that meant. Anyway, 40Mb at the time was considered prohibitively large!
I had begun my "career" a few years earlier when my parents innocently purchased a TRS-80 Color Computer (the kind that plugged into the TV) as an educational project, with help from a family friend in charge of a local bank's nascent computing division, after I'd shown interest in his. Over a couple of birthdays, etc, I acquired a bank of double sided dual head floppy disk drives and a 300 baud modem. I could read faster than that.
I'd come home from school and tie up the home phone line for an hour or so, connecting to local messaging systems in town (I realize now that my old @$$ would have to explain what a BBS was to anyone who asked). There were no usable programs, but they all had text files and messages from around the world from older tinkerers. These were files and plans for things needed to mess with the phone system and cable networks.
Turned out that, yes, it was educational!
