yo worst
how's that scope??
It is on a table next to the bench. It is in excellent mechanical condition. I powered it up long enough to figure out that channels 2,3, and 4 work; no trace on channel 1; POST fails on ATTN/ACQ board. Peeled a sticker off the back panel and discovered that it has both the deep memory and FFT option installed, along with the RS232/Centronics board. Powered it back down and it will stay that way until I can open it up, pull the boards and do the recap work.
I don't know a lot about this scope so I spent the last two days in the rabbit hole gathering manuals, schematics, mods, software, and forum threads, along with watching a couple of long dis-assembly videos by a guy whose OCD is worse than mine.
I will probably set aside the TM500 plugin repair marathon (I finished another one tonight) to work on it but I will have a look at the acquisition and processor boards before I decide.
