... 54645D ... I have this exact model and it is my go-to 'scope. You can even play Tetris on it ![Smiley :)](https://www.eevblog.com/forum/Smileys/default/xsmiley.gif.pagespeed.ic.R8GFI-pF6f.png)

That reminds me... I really need to get that GPIB module cleaned up and installed; I might have Tetris too, then...
Oh... so not all scopes were shipped with the same egg then, there were several of them ?! ... and you can change it via GPIB cool......
How nice from HP. Well I guess they didn't "allow" for that... but some bloke must have reverse engineered it I guess... he found the memory space where the egg was stored and we can use generic memory access GPIB routines to read that region of emory space to pull the egg, then write another egg to the same place... Hmmm need a GPIB module as well then... Can't wait to see what egg will be in my scope...
Nope. Those eastereggs were all from the HP engineering Dept; you can see the credits at the end of the games and right there in my Honey Badger graphic. They realized there was free space in the ROM of the scope and the GPIB adapters, and they had approval from the company to produce them.
It was still at least somewhat "Bill & Dave's HP" back then buddy. ![Wink ;)](https://www.eevblog.com/forum/Smileys/default/xwink.gif.pagespeed.ic.cldandycH0.png)

OHHHH........ OK. Looks like there is some misunderstanding here from both sides !

I mean... I never meant to say that these extra eggs were coded / created by HPAK nerds. What I meant was that it looks like there are 2 or 3 eggs (or whatever) but I assumed HP at the factory would ship scopes with any one of those eggs, randomly, so the end user would get one of the 3 (if there are 3 in total, whatever). Like, I don't know, HP decided that Week #1 they would flash egg #1 into the scopes/motherboard F/W, then Week #2 they would ship the scopes with egg #2, then Week #3 with egg #3 then go back to egg #1 and cycle like that....
So I thought that HPAK users today would use GPIB to pull the F/W from their scope, figure out where in memory the egg resides, pull it, upload it to their favorite HPAK forum/server, then every one with an HP scope could go download the eggs he does not have in his scope, and reflash his F/W via GPIB to overwrite his egg with another one ?
Like, say your scope came with Tetris, but you would like to have Asteroid. So you go to the HPAK forum, you download the binary blob for Asteroid, and flash that into your scope via GPIB. over writing your Tetris egg.
But... from what you say, do you mean that it's not like that at all... looks like you mean GPIB is not used as a means to flash a new egg into the scope F/W, no sounds like you mean the GPIB module ITSELF contains a ROM that contains an egg ? So if you plug that GPIB module, the scope can either, using different magic key sequences, either display the scopes's own egg, or go get the one that's stored inside the GPIB module ?? Is that it ? Do I get that right now or ??

I guess there are other modules available than just GPIB... does each type of module contain its own egg ? Or was GPIB the only module that had one ?
These 546xx scopes look like a lot of fun... can't wait to receive mine and play with it !!!
