The Sinclair QL was the big brother of the very first computer I ever had: the Sinclair ZX Spectrum.

The Spectrum was a very tiny domestic computer. It had a Zilog Z80 8-bits processor running at 3.5 MHz, and 48 KB of RAM available (part of it reserved to system variables and video memory).

The Spectrum was tiny, but allow me to learn BASIC with some deepness, and I was even able to wrote some programms in assembler. I remember it with a lot of nostalgia. It was May 1985 when I started to use the Spectrum.
I dreamed a lot with a QL. It had a Motorola 68000 processor, a jet plane when compared with the Z80. However, the QL was a commercial disaster, and it never reach Argentina (at least, not that I know).

Some years later, in 1991, I had my first PC-type computer, an AT-286 clone with 2 MB of RAM, a 40 MB hard disk and Hercules graphic card. 2 MB. More than 40 times the RAM of the Spectrum.

Thanks, Sirius for getting the correct link. And interesting story about your history with Sinclair computers and computing before PC’s.
