Over the weekend while moving another project out of long term storage, I
also unpacked the Hawley Mark II mouse for my SGI IRIS 1400 since I wanted
to see what it might take to repair its cord.
When I originally acquired the machine, the outer insulation of the
mouse's cord was just beginning to crumble at the ends, but 10+ years
later, it has now become extremely brittle and is completely flaking off
the cable. The cable they used for the mouse is very small diameter [my
mouse has the same cord as this one:
http://www.oldmouse.com/mouse/hawley/X063Xvanilla.shtml] and I don't think
I would be able to find a multiconductor cable that small to replace it.
The individual conductors are still tightly twisted together along with a
fiber wrapping of some sort. Since the inner conductors appear to still be
intact, I'm considering using heatshrink tubing to replace the outer
insulation, but I'm not sure if this would be the best approach or not.
In addition, the main ball doesn't turn very well and the rollers/contacts
inside the mouse also don't move. I've not yet disassembled it any further
than just lifting off the outer cover since I'm not sure of how involved
of a project this thing is going to become. [I was initially hoping it
would be a minor project to repair the cord but it's starting to look like
repairing this mouse may be pretty involved.]
Has anyone else rebuilt one of these mice, and if so are there any gotchas
I need to be watching out for?
I have some Emulex SD590 drives which require a controller like the
DEC KDA50-Q (M7164+M7165) or KDA50-QA.
I found a KDA50-Q controller on eBay, but also discovered that the
KDA50-Q has a rather bad (show-stopper) bug that was fixed in later
revisions, detailed here:
>From that description I understand I need either revision D1 or D2 of
the M7164 module. What should I be looking for on the board that would
indicate it has had the FCO applied? is it an option to re-program the
6 PROMs that appear to be involved?
Alternatively, if anyone has the two board set (M7164 and M7165 joined
with the 40-pin and 50-pin cables) along with the cab-kit up for sale
I would be interested in discussing further.
Ps Thanks Jay for getting cctalk back online, well done!
Standard CD carriers/trays for Sun type CD drives... I have 11 of
them... no physical damage although some have mild plastic yellowing.
All appear functional/usable.

fit a small flat rate box if you want the lot).
For quite some time I have been pursuing an effort to repair a PDP-11/04
system and make it running under CAPS-11. I have had it successfully boot
>from the TU60 tape drive. The plan is now to attach a contemporary console
terminal to it. I happen to have a LA30P which looks suitable and would
make it a nice looking system.
I have documented the effort here:
The LA30 is now working fine but the problem is that I don't have the M7910
or M791 card that make up the LC11 Unibus option as this terminal was once
upon a time connected to a PDP-8/E instead.
Is there anyone that have a M7910 or M791 card who wants to sell or trade
it for something?
During the restoration process of the LA30 I found that it is using quite
uncommon paper. I needs 9-7/8 inch (250 mm) wide paper. Is there a source
for this kind of paper somewhere else than in the USA?
If there is no M791 or M7910 available I have to either make my own M791 or
make a serial / parallel converter to go into the LA30P (I guess that no
one has the M7389 and M7731 boards that make it a LA30S, or?).
When looking for more information on the LC11, there were limited amount
available on the net. I did find the LC11 Decwriter System Manuel (pages
4-2 and 4-3 was missing which is quite annoying) but not the LC11 Decwriter
System Engineering Drawings. Anyone knows an online source for that one?
