For me retro Computing Hardware is like legacy PA Audio Hardware.
It stays in the past
I leave it where it is {which is way in the past} and I just work with the digital versions.
New resurrected versions of Retro Hardware have the same problems as the A4000T when I bought it. Production is low which makes the price extremely high and repairs even more expensive
I have multiple functioning SID chips so if I want to do a project I'll just get myself yap Raspberry Pi5 {I'll save for it} and I make a project where I generally the songs from an actual SID chip.
yap = yet another pie
