Hi all

I caused (I have people working for me who are really good at this)
the 8748 to be removed from the one PCB. Reading it in my Expro gives
me sort-of random results. Looks like some bits are high, some are
low, and some float all over the place. No two reads return the same
data, but some bytes are constant over two or three reads and other
bytes are constant over two or three other reads.
Is this the way an EPROM would fail? Seems reasonable to me.
Anyway, I guess I'm SOL unless I can find a working drive. As far as
I can tell these were used in the Heath / Zenith 170/170 luggables,
also in the Morrow Pivot maybe.
Tony would probably just rewrite the firmware. It's only 1024 bytes,
how hard can it be? :-) Seriously, I am thinking of reading each byte
say 100 times, averaging that, and then sticking the whole thing
through a disassembler. But it seems a bit of a mammoth task.

This statement is hurting my brain. I was never an Apple (company) user or fan but personally felt the Apple product line was hacker friendly before the Apple II c threatened to void your warranty if opened, then the Mac seemed to follow similar unfriendly EULAS.
But then again I wouldn't have guess GUI would win the UI war either when it was so great to type exactly what you needed with minimal system resources. Admittedly my opinions seem to only satisfy myself ;-)
You prefer Apple and expansions or Mac II?

Apple II days and start making the Mac II series.

Ugh.. they always get ya on the shipping.
I don't know if I'd pay $25k for Twiggys but I understand the impulse. ?The problem is, what happens when the novelty wears off? ?I also wonder what the long term value is as generations that experienced these things pass on to those who've never known a day withot a smartphone.
That's a worry for another day though. ?For now.. I'm thinking about grabbing a shovel and going digging for Twiggy gold at a certain dump in Logan.

Ah, out of touch on that, as well!
"But, you can do ANYTHING with Photoshop!" Yeah. right.
Want a stabilization processor?
Most of a ragged Beseler 45, plus a dichroic head that I never got around

Movie film daylight developing tank? (motorized back-and-forth reel to

Fujinon desktop holography camera? (needs new laser tube)
bellows for 35mm? tilt and shift? (I am keeping my

Selling my Linhof and Tachihara soon.
Just got through setting up a darkroom in my upstairs bathroom. Did some
developing years ago, but it's nice getting back into it. Looking at doing
some wet plate work next, but I haven't found a cheap source of ether yet.

Well, technically, as you probably know, the mouse came from Engelbart (well,
his group; I'm not sure who the individual was); and the display, I'm
honestly not sure of.
I know the Knight TV system at the AI Lab was a very early bit-mapped
display, but I don't know where the idea first appeared. (There were of
course influential earlier display systems, such as the one on SAGE, althoug
those were of course all stroke-based systems, given the limited memory of
the period.)
Windows and menus are AFAIK from PARC, but maybe there are antecedents I
don't know of.

Now I'm not sure how serious _you_ are being! :-)
As to the first, there is some truth to it, but like many (all) humans,
he was complex...
Hard to say what else he would have done, could he have gone on; perhaps not
so much (he was getting up there, and people do slow down), but I suspect his
early death was a serious loss (in terms of further advances).

Hi CHris - We wanted one cleaner! for the exterior view.
also 2 are good.
one can be showed set up
and
another one for people to peek inside.
OK did that with pair of Altairs which due to conditions worked
out well
had pristine looking Altair with replaced power supply and mother
board ... blah right? but left closed for exterior view in display
looks great.
had 2ed one nasty out side and front pane front... not so nice l but
inside it has the correct orig. wimpy power supply and the little
linked together mother board segments with 100 jumper wires holding each
together... this MADE A GREAT INTERIOR display.

What?s wrong with yours that you can?t clean it up for a non-operational
display?

OK anyone else have a cube out there that is cosmetically decent? does
not need to be internally complete?
Ours is a bit of a beater for the display

No. As I noted, I haven't even booted it up yet to try it. I will be
keeping that, one of the mono NeXTstations (the one for parts ) and passing on
a NeXTstation to a fellow collector. I appreciate the interest but it
hasn't even warmed up yet from the cold :)
