Yes. On thinking about it it was the early 80s. Remember the Timex Sinclair
and the Tandy TRS-80?

My first was an Osborne Model 1. I thought it was great! The 5 inch
floppies (really floppy) cost $10 (cdn) and held 92K. The screen was
just a bit small.

I remember how everyone was so excited about the Osborne because we
finaly had a portable computer!

The neat thing about the Osborne is that you could program it to make
any format floppy. In those days, each manufacturer had a different
track/sector format - with the Osborne you could create any format.

Since it weighed as much as a sewing machine, a more appropriate
phrase is "transportable." I took it to work to calculate marks. I
remember using z scores to scale marks.

I bought it after a student submitted a word processed essay (TRS 80).
And I realized that I could not mark the spelling on his essay.
Should I mark spelling on the others' essays? I began to realize
that these things might have an impact on learning and teaching.
