Thanks! I had a sneaky suspicion that it was the same battery used in the HP 70206A display only with leads attached. One is on the way, Both of these batteries are in the AA form factor and I have discovered a regular 1.5v AA can be used in a pinch in the 70206A if need be, at least long enough to get rid of the confidence check error on boot up. WOW, a NOS HP 8566B, that's quite the score. Most HP 8566B's I find on eBay are pretty beat up with an array of issues ranging from gouged front panels, missing knob caps, missing or broken rack handles, etc. Every now and then you can find a nice one. A buddy of mine who used to work for Motorola rescued one that was headed to the dumpster, all because they couldn't find one of the interconnect cables. Other instruments rescued form the dumpster included several HP 8590, 8560 spectrum analyzers, Tektronix 24xx series scopes (one is a Tektronix 2465 I got for free) and a mint Bird 43 watt meter with slugs I paid $30 for. It's astonishing what is thrown away all because they don't want to spend the time to auction it off. Once again, thanks for the help! :-+ |

Please come share some pictures of your 70k system-in-progress in the TEA thread! https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/ Beware that if you are looking for help stopping the Test Equipment Acquisition habit, it is the WRONG place!!! >:D Also, here is the post where I shared pics of my 8566B and accessories. And I agree with you, it's simultaneously amazing and sad what gets thrown away amongst rather expensive test equipment. In many cases, minimal effort is needed to get it working again if you can get your mitts on it. |

I just get IDC connectors off ebay and use ribbon cable. I then just cut the 5th and 6th wire and solder the 5th and 6th wires together on each of the ends only. It is fast and easy and works great. Edited to make directions more clear. Added another picture of cable to make clear ends of cable. |

Battery for 70k For units like 70900b manufacture part number TL-5104/P Digikey p/n 439-1013-ND For units like 70100a manufacture part number BR-2/3AT2SPN Digikey p/n P201-ND For units like 70205A manufacture part number TL-5104/P Digikey p/n 439-1012-ND There was a 2/3A used without tabs, but I think HP stopped using it, so I did not list it. |
