I'll do some homework and see what a rational offer is, but suffice it to say,
I'll probably take it. :)

Perhaps LeCroy has changed it's spots from the NIM and CAMAC days, but any
documentation, like service manuals, was completely unavailable. I tried
several times.
I am not about to buy anything where at least a schematic is not
available. I have never sent an instrument in for factory service, and

Hi
I'm more or less guessing that there's a bunch of init data in there, a
command processor for the serial i/o, and relatively little actual PLL loop

basically an analog part.

Tek went into the toilet when Danaher bought them out.
I bought a TDS1002 and could not even get the PC software to download
screen images, even after "registering".
However, registration sure did get me onto their spam list. It took at
least a hald-dozed tries to get their spam to stop.

I agree with what you have said about the markets causing bad effects on

I was a Tek aficionado for many many years. My first personal scope was a

the decades. The three scopes I own today are Tek. But everything else on

Maybe. Take into account that MCS51 OTP processors usually are 8K of code.
I use, among the others, the AT89C55 that has 20K of flash ROM. It seems
better to use a ROMless 8051 and place the code/tables in the PSD.

Hi
The closest the communications business got to this was back in the days
when Motorola would buy back all the used gear. They then carted it all off
to a crusher. Without something like that - it all will go to the scrap
merchants and be parted out.

Hi
I'd bet that there's some code in there and some data tables. Without
digging in, it's hard to say how big each is. We could easily find that
there's 24K of code in the MCS51 and a bunch of tables in the PSD813.

Hi Adrian,
Got the spec lines working now, thanks!
Yes, the DOS version. I was hoping for an updated user manual for that version
as the manual describes the other software version, and maybe a slightly later
sw version. Oh well.
Thanks for you help!

I've produced a kit to convert a Tektronix 7T11 Sampling Sweep Unit to a 7T11A

I am offering this kit at GBP22.50 (about USD36) plus postage which is GBP 5 to

I have been leaning more toward Agilent and away from Tektronix for
this very reason.

I think that for many of us, we are both professional and hobbyist Time Nuts
and companies that encourage the hobbyist will find it pays of when we make
professional purchases. Agilent seems to be learning this lesson as they put
more and more manuals for obsolete products on line.

One thing to keep in mind is that FEI is very largely a defense
contractor, so their customers, marketing, and motivation are a bit
different than the typical business-to-business model.

I am not so sure they have a lot of influence on what happens to equipment
once they sell it to an OEM (e.g., Motorola). The OEM then incorporates it
into other equipment (cell systems) which are sold to cell service providers,
which is then scrapped out and sold to scrap dealers. Realistical
I'm an EE manager and buy Agilent equipment whenever I can over other brands.
This is strongly influenced by their obsolete equipment manual policy.

OK, then maybe there are ROM bank switching as the MCS51 can't execute
beyon the 64K limit. It can be very challenging to follow a code that jumps
between 64K ROM banks. Moreover the MCS51 has to address the external RAM
by massive pointer use (the famous MOVX @DPTR,A and MOVX A,@DPTR
instructions)
Yes, never used but no doubt about the power of IDA. My opinion is: you
don't need the power of IDA for an MCS51 executable code.

Don forget the PSD813 :) It provides 128KB Flash and 8KB RAM... so it
can be a bit more complicated
