there a microcontroller you can buy with hardware crypto builtin for
pennies and crypto offload circuits you communicate with than implement
things like rsa or ecc over a SPI bus. You could run gemini on your
commodore pet probably with a setup like this, which would be useful to
have crypto offload in any IP networking cartridge for a retro
computer. High end server cards usually have this built in or via the
addition of 'cryptographic accelerators'. It's why we have standards
like AES so we can make hardware implementations of them.

Not entirely sure, but I run mine on a Pi Zero. I imagine you could go lower some.

My *guess* is that, using real retro hardware, the minimum would be an
80386 or a 68020. OpenSSL will build for 386, but you have to specify
you want it at compile time, because the default x86 32-bit build
requires a 486.
Anything older than that, especially 8 or 16 bit micros, you'll need to
either use a TLS-terminating proxy on a modern small machine (like a Pi
Zero) that speaks either Gopher or a non-TLS Gemini variant (Mercury) to
the client, and Gemini to the server; or, as someone else suggested,
offload the TLS to a modern microcontroller somehow.

The original analogy was that if Gopher was "Mercury" and HTTP was
"Apollo", then Gemini was trying to find the sweet spot between
them. Later, Solderpunk wrote up a "Mercury" spec as a kind of
argument/what-if, not as something that people should actually
implement. It's basically Gemini, but with no TLS, only one-character
response codes, and an even-more-simplified Gemtext that only includes
plain text and links as line types (no quotes, literals, or lists).
If I were actually going to implement a TLS-terminating Gemini proxy for
use with vintage computers, I'd probably have the client side speak
Gopher rather than encouraging people to actually implement Mercury.

This makes me wonder if anybody's written a version for the 6502 or 6510. It seems like a thing that could be run on, say, a C64 (which is what I'm thinking). > Anything older than that, especially 8 or 16 bit micros, you'll need to > either use a TLS-terminating proxy on a modern small machine (like a Pi Doable. > Zero) that speaks either Gopher or a non-TLS Gemini variant (Mercury) to > the client, and Gemini to the server; or, as someone else suggested, > offload the TLS to a modern microcontroller somehow. Or, maybe the core of a Zimodem running an ESP32 or ESP8266 (https://github.com/bozimmerman/Zimodem)?
