Upgrade: C64

I'm not technical, but...I upgraded from the Commodore VIC-20 to the Commodore 64. This had a whopping 64K RAM (Random Access Memory - of which, only 38K RAM was useable). Now this was the mac-daddy in my mind at the time. Before I got this, I used to go to Dixons (popular store for tech) and trial out the Commodore 64. I had moved on a little from BASIC to the much faster MACHINE CODE. A series of POKE commands would changed the border colour at such a fast rate in a loop that gave the impression that every 5 or so lines was a different colour. This was also called turbo lines. And with a few more POKE commands would also change the screen colour, so the whole screen was changing colour in lines.

But I didn't just stop there, I wanted to do some serious stuff on my Commodore 64. I bought the Commodore 64 Programmers Reference Guide - for anyone serious about programming, this was like the bible. It gave all the POKEable locations in ROM (Read Only Memory).
