Just 'rescued' two A500+'s and two A1200s (Commodore and Escom w/170MB HD) in the past 6 weeks. One of the A500+ (battery leakage) needs a new motherboard and was a parts purchase (an A500++ project).
It's been a 30 year break for me wrt to Amiga ownership: Originally, as a child, I had a ZX Spectrum 128k Plus 2, then A500, and swapped this for an A1200 which I let go about 25 years ago. I learnt to code a little on these (DICE C compiler).
But, I feel
4 is enough for me, as I need room for a Commodore 64 Ultimate and two ZX Spectrum Next Issue 3 that are inbound in the next 2-4 months or so
