I'd love to see source and to my eyes its the first really new OS on z80
family hardware
since the few from near the '80s.

I don't happen to have a P112 but versions for other hardware has me
interested.

I have S100 (Compupro, North*star, AmproLB+, SB180, BCC180, kaypros, and
more
than a few others.  Maybe I should crank a system using real late
version Z280s .

RSX (RT-11 and others) on PDP-11 is why I have a bunch of Qbus 11s as
they are
fairly small and friendly.

Wait, by 'open' do you mean 'release the bottom dust cover',
or 'disassemble and remove all plastic till the platters are fully exposed'?

By 'cleaning' do you mean blowing dust out with clean compressed air,
or some kind of all-surfaces wash & wipe? 

I'd assumed the former in both, thinking you might (like me) be new to DEC 
hardware.

If you actually want to do a thorough surface clean of the platters, how does 
one
do that anyway? Is there a proceedure recommended by DEC?
Because I may eventually need to do this on old RLO2 packs I have, as I get a
PDP 11-something system together.

 In the native long mode, that is.  If you run the CPU 32-bit, then VM86 
works.  I guess AMD didn't want to burden the architecture in case pure 
64-bit parts were made in the future.

 And also for expansion-BIOS emulation, especially with graphics adapters 
(which, accompanied by scarce to inexistent hardware documentation, made 
mode switching even trickier in Linux than it already was).  It looks like 
fully-software machine code interpretation like with QEMU is the only way 
remaining for x86-64.

The top of the middle part of the handle (this with the slider) is only glued slighly at the base 
part. With a screwdriver it is removeable  quite easy. After removing it, it reveals the secret of 
the mechanism.
Remove the plastic parts on both sides which act as hinges. Then pull the handle (with the 
"digital"-sign) outwards with some force. Possibly pry a screwdriver between the inner plastic part 
and the handle while still applying force to the handle. Eventually it will snap off the eyelets of 
the plate, which holds the disk in place.

Reassembly is a bit fiddly.

Before doing this, remove the disk from the pack, otherwise you cannot get it 
off the magnets!

 There is very little clearance in DECstation 5000 systems, like .1", as 
per the TURBOchannel specification, between the top of the Dallas chip and 
the bottom of any TURBOchannel option placed right above it (some have 
components underneath, including large ICs), and I think the risk of 
breaking such a non-standard wiring while shuffling option cards is not to 
be ignored either.  Also the design of the system box makes it very 
difficult to choose a suitable location for a distant battery holder that 
would not obstruct anything.

 So I decided to do that properly at the cost of it taking perhaps a 
little longer to rework a single chip.

 NB a CR1220 cell is supposed to last for ~8 years in this application if 
running on battery power all the time, which I think is good enough.  A 
CR2032 cell would last ~50 years, which I think is an overkill, given that 
the seal is expected to fail much earlier, like after 10 years.

 An encapsulated power module could instead be used such as the Renata 
175-0, where space permits, which would indeed last some 50 years, being 
airtight, but I haven't seen any reports of its use in this application (I 
have a couple of those on DEC NVRAM boards and last time I checked they 
still had the power to hold 1MiB SRAM memory contents after 25+ years).

Hi,

Another update in case you are interested:

I rescued a keyboard and mouse to go with the Sun2. I also installed SunOS 3.2
on disk. I took a different route: I installed FreeBSD, installed tme on top
of that and using the information at
https://people.csail.mit.edu/fredette/tme/
,
http://www.heeltoe.com/index.php?n=Retro.Sun2
 and
http://typewritten.org/Projects/Sun/8-4841.html
 I installed SunOS 3.2 from
virtual tapes onto a virtual harddrive. I then copied the virtual drive to a
real drive and hooked it up. I could then boot SunOS 3.2!

I then took the one TTL monitor I have (for the 2/50) and hooked it up to a
bwtwo. At first it did not work, apparently it must be in a specific slot. I
added 1MB as well, so the cage is fully populated. That extra MB is used by
the btwo. The monitor still worked and I was able to run the graphical
windowing system.

I had the system on the internet for a couple of hours yesterday, some people
logged in remotely and it still felt surprisingly fast. Only when you start
hammering the disk it is slow (SCSI-1 is slower than ESDI drives I read).

I made a movie of the box, it can be viewed here: https://youtu.be/CoAYs0Uc7As


Cheers,
Walter.

Ha, this made me realize I don't know either. Despite that I now have some 
RLO3K-DC
packs, and one RLO2 drive.

Dug one out. After a few moments of being stumped, found the trick. Here's how:

On the blue handle, top center, look on the section that has the pivot pins.
There is a flat plastic 'button' on which one end is slightly concave.
With the handle DOWN (flat), put finger on that concave end of the button, and
push sideways, till the button reaches the end of travel.
With it still at end of travel, lift the handle up to vertical. At about 45 
degrees
(half way) you'll feel a resistance, then hear a thump.
Once the handle is vertical, lift the pack up by the handle. The lower cover is
separated and the disk is exposed.

But it still is mostly covered, only a slot for the heads is open.
You could lever open the several latches that hold the bottom inner cover on if 
you wanted.

I was curious to see if there would be any replies to this. I have just shy
of 40 RL02 packs, and a few of them had bad scratches rendering them
useless. Therefore, I attempted to open them in a non-destructive way, just
to see if it was possible. So far, I haven't had much luck. Also, I noted
that while all the packs I attempted were DEC (not clones), they did have
