I started with a Sinclair Spectrum 48K too.
I ended up writing a "complete" graphics suite for it, in Spectrum Basic...not to mention a MIDI step sequencer for my synth.

My first PC was a 486 DX 40 with 8 Mb of memory, a 340 Mb hard drive, and a 15" monitor.
The upgrade from 4 Mb of memory to 8 Mb was £120.00 and a Soundblaster 16 plus a Panasonic CD-Rom drive cost another £249.00.  Toss in £99.00 for a hand scanner (256 gray scale of course) and £129.00 for a 250 Mb tape streamer and the whole setup clocked in at £2440.04.

That was in 1994.
