I am sorely tempted, but I have too many projects right now and I have to downsize in the near future as well. Looks like a 1A4 plugin in it as well. If someone is interested, I could pick it up and

Jim I spend way to many hours hours checking out the trigger components until I noticed the main line going into the trigger IC appeared to be quite thin so I checked the trace and found it was open.

Ho Roy, It's not as fast as the 547, probably more like a storage version of the 545. I used one for a while until I found a 547. It's a great performer but can have the HV transformer thermal

Paul, I guess there is no premium for all the dust! (Seems to me that 20 minutes with windex and paper towels and a toothbrush would make it way more attractive!) I wonder if the 549 is the storage

I bet she cleans up nice. Too bad it's too far for me or cheap shipping.

Not related, but looks decent for a reasonable price. It's been on and off the list for a bit and now has a lower

I think that have one cal rom from this unit. If you need i can try to find it and to read it for you. It is packed with some resistors 0.1%. Can to check the values too.

Still looking for a TU-75B in good or better original condition. $400 for the right one. It's got to be a good one. Rolynn Clatskanie, OR

Could people please take the MacOS vs. Windows discussion to an appropriate forum? It has nothing to do with Dennis's post, or TekScopes.

Apologies, please ignore this. I had intended to post this to the HP Group.

Hello everyone, Does anyone have the self-test diag rom images for the 4192A? If not, how many people have brought them back to life without the ROM, and how much of a headache was it? They appear to

Amen I haven't seen the blue screen of death since XP died. Liked WIN7 better than WIN10  . I finally moved to 10 this summer glad I waited but the transition has been relatively painless Dave --

Thanks for the response, Richard. I will look at the board carefully to make sure it's not something that simple. I'm leaning toward thinking it's the trigger chips. I just found out that the TDS694C

Years ago Apple advertised the Mac as "the computer for the rest of us." I tried it and concluded that it may have been the computer for the rest of you, but it wasn't the computer for me. My computer

Jim This may not help but I had the same problem with a TDS640. The problem was a trace on the board which was to thin and failed. Worth a look. Regards Richard

True for me! My Macs work every time I start them, all day. I can't say that for PCs, even the ones I'm forced to use at work. I started out with MS DOS and an IBM XT. Upgraded CPUs and motherboards
