might fit the needs
No, I didn't the phrase first. A VMware engineer who helped me in running a version of BTRON-specfication desktop OS (mentioned in the above post) inside VMware running under x86 Linux used the phrase during e-mail exchange as in "an off beat OS like this one helps us in locating dormant bugs."
Seriously, since TRON project produced many results (not only OS,) a broader category name may be necessary.
"Less known computing platform" might fit the bill. "Road less travelled" may also fit the bill since someone else's post mentioned Zen (and motorcycle maintenance, anyone?).
