(Data I/O), so much more reason to be careful. Possibiliies are infinite and
have to watch for fine print (manufacturer, IC revision, algoritham revision
etc.), or you will fry the PROM.

Thanks for the heads-up.

Hi All,

If the 2716 is a problem, you might want to go for the CAT28C16
EEPROM
This one is pin-compatble and still avalable from Catalyst (or any
other 28C16 which you can get)

eBay scope

Craig Sawyers <c.sawyers@...>
 

Interesting and good price rare item lurking on eBay at the moment. A 7514
storage scope - I had no idea that Tek did split screen storage into the
7000 series until I saw this. 90MHz bandwidth.

Anyway with an interesting set of plug ins, he has it on for $75 buy-it-now.
Item number is 3802548425

Re: For your consideration

Craig Sawyers <c.sawyers@...>
 

Perhaps 35 years ago I received a letter >from a company field rep< in
which he misspelled it!
I worked for a company called Scientific Generics at one stage, and received
a letter from a pharmaceuticals company addressed to Cystic Genetics.
Sounded very painful to me...

Re: For your consideration

Craig Sawyers <c.sawyers@...>
 

I once saw a list composed by the Tektronix mail room of all the various
ways "Tektronix" had been spelled on letters that still made to
the company.
Unfortunately, I did not keep a copy of it. I just laughed a lot! There
are at least 30 ways to misspell it.
It seems even worse than my name. I've had main come to Sawyer, Saywer,
Saywers, Saunders, Swyear, Sowear etc etc. My off the cuff reply when
someone on the phone asks how to spell my name is to say "Like Tom, but with
an S on the end", but it seems that the adventures of Tom Sawyer isn't a
standard text at school these days...

Another consideration is speed, but as densities went up, so did the speed.
If PCB is poorly decoupled, higher speed might work against you, but that is
not very likely to happen.

With thanks to 'Greyhawk,' a pair of firmware image files for the 7B90P
programmable timebase are now available. Note that these images are 2048
byte, meaning that they were most likely designed to program into a 2716.
Considering that 2716's may be pretty hard to find, advice on whether
they'll work in a 2732 or even a 2764 would be welcome.

Keep the peace(es).

7000 series PI interface

Craig Sawyers <c.sawyers@...>
 

Hi all

I'm building up a pair of flexible extenders for the 7000 series (because
the price is stratospheric on eBay), and was wondering why all but three
connections are made end to end when so few seem to be used by any one
plug-in.

Starting from the list on Mark Kahrs site, which has a lot of connections
listed as not used, I've built up a more complete picture. Most of the
seemingly not used connections are used for the GPIB interface for the
programmable plug-ins (7A16P, 7A29P and 7B90P), and for additional
+5.1V/-5.2V supplies.

Anyway, if anyone would like a copy of the file (Excel) let me know and I'll
pass it on.

Cheers

Craig

Just given a solid state Phillips scope - good condx EXCEPT none of the
half-turn dzus type quick release fasteners that fasten the cabinet top and
bottom to the scope chassis work. The screw heads turn, but they don't
"grab" on anything...

If anybody on the list has any experience with Phillips scopes pls contact

I have a 100Mhz Hewlet Packard 1740A and one of the
new Fluke Digital combi scopes.
Hello Christian,
Someone said that you worked on car kits. I understand that is enough of a
punishment, you did not have to take on hp 1740A, you paid your dues with
kits. hp 1740 will give you good excercise in setting trigger level, somehow
that thing always wanders around.

I am looking for all valve scope next. Since I am doing a lot of
work with high voltage power supplies and believe that valve
technology it a bit more tolerant than the modern stuff. I was
reading about the comments on lethality of high voltage. I used to
work on laser scanning systems but now in the rail industry. I often
worked on 15Kv and 450 Volts Dc. Don't get much chance of the MCB
tripping either since its rated a 44k Amp.

Best regards Christian.
