I think this tells us why the ‘ownership’ of computers is the way it is
now! As another writer wrote recently, and I apologize for not remembering
his name, says: “Rights to your own machine are hobbled by legal
restrictions” and I’ll add security concerns. We live in a much different
world than what was in the 70’s and 80’s. Firmware plays an equal role as
access to root system isn’t possible; booting a computer was possible at
root level-not now; BIOS/UEFI are paramount these days and access to TPM
isn’t possible for average computer users. One’s computer must not be
susceptible to unauthorized individuals or even now it seems the owner.

Here's one: Cramer Intel 8080A Microcomputer
https://vintagecomputer.net/browse_thread.cfm?id=819
Wire-wrapped 8080 system built to compete in the Altair market, and
flopped.
" Cramer Electronics Incorporated started advertising this 8080 kit
microcomputer, the "Cramerkit", in late 1975 for $495 (or was it $1495?)
but none were delivered until the spring of 1976. The Cramerkit was
designed by Microcomputer Technique Inc. and was shipped partially
assembled. "

Who has strange or one of a kind computers out
there?
I have a 18 bit homebrew (cpld) with 256Kb ram and just a
bootstrap loader.
I built a 32-bit bit slice processor out of AMD 2903 and
2910 parts. See:
https://pico-systems.com/stories/1982.html
I did write a micro assembler for it and ran a few test
programs. But, the work ahead of me (interfacing memory and
an I/O bus, writing 360 microcode and coming up with a
Pascal compiler and writing my own OS and editor, etc. was
just too daunting and I gave up on it.
