The CRT from an SE would work. Mono CRTs such as these are usually
interchangable (at least the ones that I have changed), but if you use one

to yoke which may be more than you want a do (though on a mono display
alignment is pretty easy). My first Mac was a Plus that has been dropped,
I replaced the CRT with an Amber one removed from a luggable XT. It was
the same size, mounting and pinout. The yoke from the original CRT fit
okay.

While I can get a senior discount at restaurants, that

Does it?

I don't think the Gyro Mouse was ever meant as a normal mouse
replacement. I think it was meant for doing presentations, where you
would most likely not have a surface to run the mouse over as you would
be standing in the front of some group, and could do nothing more than
wave your hand.
In that context, the design was fantastic... but yeah, I think it would
have been a PITA to use in place of a normal mouse.

I use a mouse (two of them, one for my Mac, one for my PC), also have two
keyboards... but I hardly have a clean desk... I have just barely enough
room to move the mice on a pad (at current, I have my soda cup sitting on
the corner of the pad as it was the only clear spot on my desk).
I just turn the mouse tracking speed WAY up, so that I can cover the
screen with just a slight flick of the wrist.

I've always thought that the proper place for ports on a _desk-top_ system
is on the side: easy to get to the ports and you don't have the cable
connectors sticking out the back, where they add to the depth, which can be
a problem on a narrow countertop. When I built my first IBM-PC clone (in a
nice cherry-stained wooden case), I turned the motherboard 90 degrees CW so
the ports were on the right. I also made brackets from cookie-sheet aluminum
to mount the disk drives and power supply over the (now) front of the
motherboard, resulting in a nice, shallow case.

Indeed, a friend of mine who owns a business that makes rackmount systems
made a special model for a customer where they pretty much did this. They
put the mounting flange on the back of the box, making it the front, and
added cut-outs for the disk drives.

There was an article on scratch-building models in a recent Model Railroad
Craftsman magazine that said that, no matter how big your work bench, sooner
or later, you'll end up with about two square feet of usable, clear
workspace.
BTW, I use an arcade model track ball that was a prototype for a museum
exhibit installation 10 years ago (and thus on topic). I've only needed to
oil the bearings once, about 6 months ago. Never had to clean it. Try that
with a mouse!

Hello,
I just scored a PEP-70/Hypercache pair from a guy on eBay and in my
conversations
with him, I've learned that he has a couple of working 11/70s, one with
conventional
MOS memory and the other with a PEP-70/Hypercache pair. He is a dealer and
I have
no association with him other than my eBay purchase. He seems like a nice
enough
fellow and these things are not getting any easier to find. So, for those
who are inclined
to spend money on their hobby computers instead of on PCs, here is the info.

Nope, 2910 is a microprogram address sequencer for the 2901 series.
There are, however, a number of "2901 with more bits" chips, however. The
IDT IDT49402/IDT49410A is the equivalent of 4 2901 slices (16-bits) + the
apropos microprogram sequencer logic. Cypress had the CY7C9101, which was
similar. WSI had the WS59032, which consisted of 8 2901 equivalents.
Innovasic has the IA59032, which is an ASIC reimplimentation of the WSI chip
and is still availible.

Thanks to all who replied, it was the 76477 chip I was thinking
of, and thanks for the links to the PDF files! Appreciate it!

I've got a bunch of NCR (Symbios) Class 6299 Model 1100 raid subsystems,
and they have a DA-15 console port, for which I can't find any pinout
information. Does anyone have a pinout available or information on these?
I've tried googling everything I could think of, but no luck. I know the
information is in their 'Site Preparation Guide', which Purdue had, but
got lost. Also, NCR doesn't seem to carry documentation for these on
their website.
Thanks for any information.
