Hello Walter, would you happen to have a replacement window for a HP 34401a ?
Mine ie scratched up bad and would like to replace it.?
Thank you,

I have an HP floppy with the 8530A FW V 1.60 and an 8530A with the 8510C FW loaded. I would love to get a floppy image for the 8510C FW so I can switch between the two.

As far as I understand the 8510C On-Site Service Manual (08510-90282)
page 9-20: Making a Backup Operating System Disk
This function is intended exactly for that purpose.
Function 19 is "Load Program Disc" which I assume does the reverse.

Of course I have never tested this yet.

So you should be able to backup your 8510C and then load the 8350A. But
do test your disk somehow as mine are all old and shaky.

Best regards,

There is no options in 8340B that would've added something or made it better

Option 007 is relaxed phase noise, page 1-10.

Thanks, Sergey.? I have updated my "wishlist" HP 8340 entry to add "best with no
options".

BTW, do you see your own text below?? When I reply, I see the previous text on my
screen, and when I receive my own reply as posted to the group, it contains the
other text as well.? Therefore, I haven't made any effort to copy text from
previous posts.? But I've often wondered if others see the previous text.? It bugs
the crap out of me to see somebody else's "Yeah, I agree" post, for example, with
no context.

Those people who post a single "Me too!" letters are mentally ill and it is
a sin to insult them. Thou shalt forgive them; for they know not what they
do...

Your quoting is fine; it is somebody else that screwed up earlier message
text making it all one long line without breaks.

Sorry, but I can't see much there. Do you remember having to use a
hacksaw, drill, file, oxy-acatelyne welder, pneumatic grinder, sawzall,
jackhammer, etc?
