This was my first computer
The modem looked like timbers. There was no disk drive but you could save data to an audio tape player.
There was no internet, but people operated what we called BBS. You could dial up to one computer and leave messages or information.
I remember being very proud that I upgraded my memory to 4KBytes of RAM. that is 4,000 bytes compared to the 512,000,000 that now seems insufficient in my current computer.
My first connection to the internet was with DarpaNet when I was working for a government contractor on a Sun system. Does anyone else here remember being shut down by the Rob Morris worm?
