I was lucky and kept everything i had, only selling off some lesser systems to upgrade.I still have my C64 breadbox from 83' and the c128dcr. I started on a ti99/4a(still have it too!)
For Amiga I started on a A2000 in 87' that was decked out with accelerator,scsi,cdrom. cdroms were crazy expensive for 1x speed then.
Sold it off to move to a A3000 in 89' a fine full 32bit machine with zorro3,added A3640 040 card,16MB zip ram,a cd rom externally and i think a new 540MB hd..a little power house.
In 92' i got a deal on a A4000 from a friend and added a Warpengine 040/40,fastlane z3,AriadneII,larger drives,16MBram.A2386 bridgeboard,life was good.
Later expanded to a Cyberstorm PPC,large ultrawide scsi hd's which were speedy!,PicassoIV,ad516 sound card. I picked alot of the stuff up as people were dumping Amiga stuff for good prices. That system carried me for a long time having 1024x768 24
bit gfx was nice and i did everything on it,it was my daily machine.I did banking and credit card sites etc.
Eventually all of that was put into a elbox mediator pro tower with pci slots,adding a voodoo3 in with the picasso IV, deneb USB,goldenGate 486 bridgeboard,100Mbit ethernet,Terratec 512I sound,Hauppaug TV card.
Its ran 24/7/365 since 92/ and was never down except for hardware additions,bad AT power supplies etc. i run the same 4000 today with a 256MB ssd on the ultrawide scsi via acard 7720U. its served me well and never missed a beat.
Over the years i got alot of amiga hw from dumspters,people tossing stuff,giving me broken motherboards,some bought from ebay etc etc. repaired tons of amiga stuff in 20 years and i have way too much these days,with a stack that still needs fixed/recapped.
among the stuff was several a4000t's,a3000t's,a3000's,2000's,2500,cd32,cdtv,a500's,1200's,600.

I knew i would regret selling anything, so while most people dumped their amigas in the 90's i tried to buy what i could afford, prices were super cheap,and things like a3000ux sold for trivial prices. i passed on so much cool hardware then due to lack of money. i only regret i could'nt save more Amiga HW from being thrown away.. why people dont simply give unwanted hardware away or sell it is beyond me,so much tossed in the dump.
