I have an hp 54645A that I got for $100 on eBay and I love it! Mine is only 100mhz, but I primarily work on audio equipment, so I really don’t need a super fast scope. Be careful not to push on the knobs on the front panel, the pcb is brittle and prone to cracking, I had to fix 2 broken traces in order to get the channel 2 controls to work correctly.
Hi Thomas, beautiful digital with CRT screen, thanks to the deflection coil system it is not so deep, the automatic functions on the cursors are perfect. I am not sure, but I think Hameg also had these hidden games. Nice day 🙂 Tom
I had a very similar, slightly newer one which had an almost arcade-perfect (at least gameplay wise) version of Centipede (which also has a highscore list - mine had some very low scoring entries tho, I got over 50k). I've also heard of Asteroids. Those programmers really had too much time. If you hit the 2nd and 4th buttons in that menu (or was it 3rd and 4th?) there is another easter egg that shows a photo of what looks like a skunk and the names of the programmers (and you can still use the scope while it's rendering, it just doesn't react to button presses). IIRC mine was from 1997. I passed it on to a friend.
@@TeardownOZ2CPU Maybe yours doesn't have it. Mine is from '97. On the Print / Utility menu, there were three unpopulated menu entries (from left to right button 2, 3, 4). Pressing 2+3 gets you the game, pressing 2+4 gets you the 2nd egg. Or was it 3+4?
Back when those were introduced, I think I was lusting for one for a while. My girlfriend had a lot of fun with me having “hp pamphlets under the bed”. I had The Catalog and one or two brochures advertising those. I then got to use them in a student electronics lab. I often have to stop myself from considering buying one even now :)
@ 😅I was spoiled - I grew up with a decent lab at home. Still, DSOs had an allure that was hard to beat. I appreciate that growing up with a CRO taught me lots of tricks to make once-in-a-while events become repetitive to see them clearly.
those one are iconic scopes even for today standards

I'll have the 54616B. Indeed a top oscilloscope. Part of the manual is a very nice & lucid manual on how FFT's works.
I have the same scope, what concerns me are the tantalum capacitors nested in the main board......congrat for the video

can you please explain in more detail how to activate that 2nd egg ? we tried all, no luck..

Holu crap, what a condition of the device!
Probably, the tetris game was actually a hardware test developed before the actual application software?
lol my oscilloscope
