Very nice collection. I was purely focused on all-in-one 'keyboard home computers' that were designed to connect to a TV or composite monitor since that's the first kind of computer I got (circa 1981). So I have all the Ataris, Amigas, Commodores, Sinclairs, Apples, etc which fit that description. Plus a bunch of overseas models from all over the world. Well over a hundred unique models now, including some extremely rare ones.
Fortunately, I started my collection in the early 90s and finished by around 2000 (since I pretty much had one of every machine that fit my style). Gathering them when everyone was just giving away or trashing those machines meant I never paid more than $25 + shipping for any of them. My teenager started looking them up on eBay and said got to over $100,000 in current value before doing even half of them. I told her to stop because they aren't worth anything since they're not for sale. I wanted them them when they were trash no one cared about and that hasn't changed now that they're "vintage collectables" :-)
