I had a Texas Instruments that was smaller than an ipad. It had a whopping 16KB memory pack that plugged into it and was about the size of an old mouse. Shortly after that, I went to Commodore and never went back. I had a VIC20, a 64 and a 128. I didn't get the Amiga. My buddy and I interfaced to the VIC 20 to create an 8 bay power supply tester. He did the hardware AtoD converter and I wrote the software in machine language no less. They sold an EEPROM blower so that we could make a cartridge that would start up the program when we turned on the computer. Those Commodores were pretty powerful. I remember spending a couple of hundred bucks at Lechmere on an old dot matrix printer that printed at about 10 characters per hour (LOL - slight exaggeration). Then I got an IBM 286 and spent an additional couple of hundred on memory sticks that I think got me 8MB more RAM. I also had a couple of huge monsters from Nixdorf that ran CPM on which I was able to play wonderful amber PONG games.
