Minix on PDP11, Not that I know of. It would be interesting.
Allison
The reason I bought Minix in the beginning was
that it would run on my
PC/XT machine (the only PC I had at the time). And I learnt a fair bit
about OSes and enough C to be dangerous by playing about with it.
Yes indeed
8MB and a 386 is not a small machine!
8MB and the equivalent of a 386 is getting to be pretty close to a single
chip these days.
Feel like porting Unix V6 (as in the Lions Book)?
I quite fancy porting Minix to the PDP-11, but I'm sure it's been done
before.
Gordon.

Well I think Minix #1, would be easy to port, but why? You got real unix.
It just proves how effective code on the 11 could be. Too bad you can't buy
a pdp-11 cpu chip for $2.49 like a 8088. I take it is still rather pricy
to put together
a basic 11. Any body know how much?

Alternatively, anyone got an RXV21, RL02 cable and terminator they can
sell me?

New subject: RL01/RL02 cables (was Re: Minix)
I'm in the market for an RL01/RL02 cable myself. It seems mine is
broken. In fact, if anyone in the NH/MA area has one they could loan
me for a short time, I could at least verify that the RL01 drive and
controller work before putting more effort into finding a replacement
cable or trying to fix the broken one.
Anyone in the MA/NH area have an RL01/RL02 cable they could loan me
(or sell me)?

I can't sell you mine, but you can borrow it. I know it worked about 6
months ago with my RL02. I have a working RL02.
I may actually have something else which may work in my box-o-cables.
I'm in Arlington if you want to stop by, pretty much any day 9-6 but
you should call ahead as I be an en-ga-neer and you know how those types
can be :-)

Well what about a whole set ? A lot of people like myself can't be
mix-ing and matching
part. I just want to pen the box and plug it in if I were to buy one.
PS A small HD would be nice too. I got a terminal already

opto-isolated I/O cards I got from eBay too, they should be fun!
I got (from a bloke in Australia, just beating a chip collector) on eBay
the following: M8047, M8043 and M7270.
The M7270 is a cpu, and the M8047 has some memory, bootstrap ROMs and
two SLUs on board. I could build a very nice portable RT-11 machine
just with that!
Wonder what the current draw is?

Don't forget XINU which was designed to run on PDP-11s.

I haven't looked, but I would have thought that you could buy
something like a PDP-11/03 for not a lot of money (assuming that the
11/03 is what I think it is - small Qbus system, yes?)
