The Adam computer we didn't end up getting would have been near the end of 1984 (right when winter was getting harsh). That I remember very clearly.
The C64c that we got was about 1986. And the floppy disk drive about a year later. We had to buy a printer first to make it a justifiable expense. That was the Star NX1000 dotmatrix printer. We had to buy and interface card for that too which added another $75 CDN.
