Is there any reason for a telco to worry about the number of phones in a
house besides for purely financial concerns? Of course, if you have 100
phones all plugged in, it's possible there won't be enough power for all
of them, and certainly not enough to make them all ring. I believe the
FCC controls stuff about the amount of power a phone can use for
ringing.

Back then SA4000, Memorex M101s were as common as the new ST506/412
drives. I have a M101 here operational on a CCS s100 crate big and
like most of the 8"s clear plastc cover to watch the goings on.

i've got just about every compact mac model made except for a 128. while
selling some things at a radio rally today, i came across a guy who said he
had a complete working one for sale. turns out this guy even works in the same
facility i do! here's what i got for $10
imagewriter // in original box.
mac128 in its original box with manuals and system disks. also has keyboard
and mouse in their boxes also along with the purchase list and other
literature. machine is dirty and will have to be disassembled and cleaned. one
thing he told me is that it has some sort of scsi upgrade. the battery door
has been replaced with a db25 connector so im not sure if it has a genuine 128
board in there. nonetheless, i will keep it in its current modified status
because the upgrade it's had is almost as "rare" as the machine itself. i also
have a lead on another guy that has about 30 compact macs in several designs:
512, plus,se and probably some more 128 models which i might also get. for
some reason, i couldnt sell all the plus and 512k models i had...

Is that enough to actually do some decent stuff with the PDP-8.

I also have some reels of film-like tape. What's the proper name for it?
How does it compare to the paper tape?
Thanks.

Do those panels have any circuitry in the back? Switches that are
stamped with the date? Could you make pictures of the back as well?

I picked up a PDP-8, 8L, 11/20, and a bunch of accessories this week.
That PDP-8 is one cool looking computer.
Of interest in the lot was a "high speed paper tape reader" and quite a
bit of tape. The tape, one inch thick, looks to be of incredibly low
density. Just how much does this stuff hold?
More questions to come as I learn more about the PDP's. Thanks in
advance.

P.S. I'm looking for an inexpensive Mac Classic or SE, 4/40
configuration, w/kb & mouse. Anybody?

My friend reports that the Graduate doesn't have a BBC ROM, and indeed
doesn't use the Tube. It uses the 1MHz bus to access BBC I/O, apparently.

Thankfully, I was using a T1 at the time I first looked at this page and
didn't notice the size of the images. The first thing you should do is
reduce them from RGB to Grayscale. I tried it and it doesn't reduce
image quality at all. Also, does anyone currently own the rights to
this? I would like to make an HTML and DVI version of it, which would be
much easier to read, since it wouldn't involve as much horizontal
scrolling.
Now, some questions about the computer itself.
A) How much did it cost in 1998 dollars?
B) Was there ever a DIGI-COMP II?
C) What type of plastic was used in it?
D) Has anyone tried to make one?
E) How popular was it?
F) What year was it terminated?
Basically, a brief history.
