I vote for either the Altair or ZX-80/81. ;)

Now there's a micro-kernal for you!
There was a great tfile on usenet about a AT&T SYSV port to timex-
sinclair. The only problem was paging to the cassette recorder when the PF>sysadin was using it for audio tape playback.
Is this the one? (by the way, it was you who posted it on BTF :)
ZX80/81 owners unite. Research is currently underway into a version
of UNIX for the stock standard ZX81, call ZUNIX. Using a new mega
super ultra data compression method (involves a hyrdraulic press) the
follow features have been implemented in ZUNIX -
* Runs in the standard 1.5K. No need to go for that wasteful
extra 4K or 16K RAM upgrade.
* Will be licensed in 100 and 200 user versions
* Efficient paging and swapping to cassette tape at 300 baud.
Later versions will support multiple cassette recorders for really
high performance IO.
* Includes all Unix tools, networking and X. Full source included.
* Able to fully use all expanded and extended memory (i.e above
the 1.5K limit)
* Includes software to emulate a PC running MSDOS (similar to VPIX
and DOS MERGE).
* Support for Hyperchannel Interface (enables CRAY to be used as
a frontend)
* Support for real time processes.
We've been beta testing ZUNIX for the past year, using 150 developers,
all going through the edit-compile-link cycle all day. The only performance degradation we've noticed is when Jeff (the ZX81 is on his desk) has
to swap cassette tapes. Even this will be fixed when we write the
drivers for multiple cassette recorders. Can't wait!!
ZUNIX is expected to sell in the $1.50 -> $2.00 range, on a single cassette tape, from <J>oint <O>perational <K>ode <E>ngineering. Even after ZUNIX
has been fully implemented we anticipate there will be (as you can
imagine) a large amount of the 1.5K main memory free. To this end we
invite you to post your suggestions for further features that could
be implemented in the remaining space (eg traffic control system for
large city).
