The worst thing about emulation is that the “feel,” of the original hardware doesn’t seem to be there. Simh can emulate tons of hardware from different manufacturers, but none of that will tell me what it was like to actually use the devices in a physical sense.

I have little conception of the shape or size of many of these notional machines, and they are all reduced to various abstractions at a console prompt. It’s hard to imagine a thing I was far too young to experience.

Its kind of useless from a  practical standpoint, but a lot of my interest in these machines isn’t practical to begin with. I want to explore an earlier kind of computing, but don’t expect to get a job with it or have anything beyond some entertainment.

It's perfectly reasonable to see with other senses.

One good source is youtube videos.  There are a lot of them with audio
of computer peripherals.

Here are a few:

tape.

Google search 'videos' for your choice of hardware and there's a good
chance you'll find more.

For physical size, nothing beats a museum, where you can also get a feel
for texture, relationship of components, and, if you're lucky,
interact.  If you have a good describer on tap, you can get maybe 20% of
that watching the videos with him/her.
