Re: zilog system 8000

[Evan Koblentz via cctalk]

A very big and expensive door stopper without OS tapes.
But most importantly: the CPU board is missing!
The card in slot 2 appears to be an additional SIO card.

This is a model 20, quite low-end. We have a model 32 (much rarer, I
haven't found anyone else with a model 32), but it is non-functional
because I have no tapes. The SMD disk has too many errors to recover a
functional system.



There's a Model 31 at LCM+L (used to be mine).  If anyone ever does recover
media for these things, it'd be nice to get it running...

- Josh


VCF has one but I'm not sure which model it is. I can check next week. 
We also have some tapes, again, I don't know which ones.

Next week, I'll check which sub-models.

My 5150s, 5160s, and 5170s are very far from "clean".  Functionality over 
esthetics.  Additional mounting holes, some have additional DB25 and 
DC37 cutouts in back, some don't have lids (a few never did), one 5170 had 
bad case damage when a bookcase landed on it during Loma Prieta, etc.


My first 5150 started life with the white switch black power supply.
A decade ago, the college dumpstered the collection of one of my 
colleagues; besides IMSAI, ProcTech, N*, he had had a few dozen clean 
5150s and 5170s, including several of the "gold-badge" 5170s.

Not to worry.
I also have a few boxes of old books and IBM slip-case manuals (techRef,

a dozen HP "pinch to close shutter" 3.5" disks, a Shugart 3.5" from before

I'm not healthy enough (last year I had another TURP surgery, instead of

If a person is going to dabble with modems, these are as good as it gets.

If you don't mind shipping, and you're just looking for compensation for
shipping costs and packaging, I'd take a couple (assuming you're .us or
.ca), but there is still a little demand for these.  There is nothing
better.  (There are a few more interesting modems, like acoustic coupler
modems and some of the Telebit stuff, but for practical usage, a v.92
v.Everything Courier is top of the heap.)

Re: GoTEK SFR1M44-U100...

[dwight via cctalk]

One thing that bothers me is the continued emphasis on arithmetic and not on 
mathematics. The kids growing up today will rarely be more than a few feet from 
a calculator. The first thing on the math test was the "No calculator allowed". 
I'm not saying that they shouldn't be taught arithmetic but it should be the 
minimum necessary to recreate a multiplication, square, divide or what ever 
table. Knowing what 43 * 67 is on an exam is useless in determining if the kid 
can learn calculus or understand how it relates to the real world.

About the hardest math a person might need to know how do do by themselves it 
to figure the tip at a restaurant. And even then, if the cell phone is charged 
it will do it for them.

It's a fair point, and one that did occur to me, but I didn't want to
be even _more_ prolix and hedge it about with disclaimers.

Yes, education for all is a relatively modern thing. In the days when
it was for the elite few, well, I suppose it *would* be more tailored
for the elite, and thus would be challenging to non-elite, even
generations later.

But I am nonetheless surprised at by just how much.

I've found .BIN files for the firmware, but no information on the actual
MCU used in these things.  Not even a datasheet.  My guess is that it's
probably an offshoot of a CH375 core.  But that's not a lot to go on.

Maybe it's a case of "you had to be there".

Not being very active on this list, I hadn't realized that you needed
one. I'm delighted to hear that you got one and wish you a full and
speedy recovery.

A very big and expensive door stopper without OS tapes.
But most importantly: the CPU board is missing!
The card in slot 2 appears to be an additional SIO card.

This is a model 20, quite low-end. We have a model 32 (much rarer, I 
haven't found anyone else with a model 32), but it is non-functional 
because I have no tapes. The SMD disk has too many errors to recover a 
functional system.

Wow!  solid state memory and ECL chips for the CPU!  Going

You'd need a disk control and drives and a comm control to

Re: Info, spice model parameters for DEC pulse transformers?

[Joseph Oswald via cctalk]

Thanks for the response. I had seen your info on the two other parts.
Unfortunately, I have no idea if these system modules exist outside a
museum.

I might have to back off even further and work out a technique on
something like the B301 or B611 modules, which seem to be obtainable
and at least vaguely similar to the transformer circuits I am
interested in.

Can you detail a little more what your measurement method is? Do you
have an LRC meter or something, and measure the resistance +
inductance open-circuit? At what frequency?
