I think you mean QNX ? I've got the CD, but no time to test it.
Apparently it's rock-stable and also compact. But Oberon gives me
access to a good source language - which you may not want.
I think Oberon S3 will give you a full OS with compiler, editor(s),
inet news & emailer & http-get on a single 1M4 diskette.

I started on an old 386 16 Mb, were I partitioned the 80 MB to give
about a 20 Mb for Ver 2.3.2 native-oberon.
If you don't want to allocate a partition, you can use the DOS-based
version; I've got DOS-based Ver 2.3.6 and can confirm that it's
stable. Currently I use '2001 StandAlone' version which was one
of the first to handle multiple partitions (since I'm a heavy-volume
user, the 'flat-file-system' [no directories] is problematic, unless I
can separate my work into several partitions).
Here's what a small part of my 'Techn:' partition's dir looks like:
Techn:A2D.html.Bak
Techn:AWV
Techn:AWV.Bak
Techn:AmtSatlFAQ.html Techn:Asm86 .....


Yes, and other communual radio technologies are growing.
The important point is that, you don't need 'real-time', i.e. your
messages can travel slowly during the night (cheap rate) time.

Yes, but it's the per-use cost that matters, not the ownership cost.

Absolutely ! Progress is by knowledge; not by apeing Micro$oft,
Macdonalds and Disney.

BTW. If you lack http facilities, this can all be done by email.
I had a spam wave (since 18 Sept - and according to news-post,
so did other victims), but I'm posting this also to news:comp.lang.oberon
where we can communicate, if my email is disabled.
And Oberon S3 has it's own mailing list, but most users are playing
at the 'bleeding edge' with research and don't have motivation
to help beginners.
