I think this is probably a good point to call it a night. ;) mnem :-BROKE --- End quote --- Hi Dwagon, Did you see my posts https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/msg4275517/#msg4275517 and https://www.eevblog.com/forum/testgear/test-equipment-anonymous-(tea)-group-therapy-thread/msg4275556/#msg4275556 Looks like same video scheme as the 892x series a Gondbes 8220 video converter would be my next stop. --- End quote --- Yup, sure did; and followed that rabbit-hole down to that LCD mod. Very tidy! :-+ Problem is that the models we have tech ref on... the ones we've been talking about... are all proper non-greyscale monochrome monitors. Also, this family of monitors are all "1000 line" resolution (IIRC, I read that they "use" ~960 lines), so not too sanguine aboot dropping down to 800x600 resolution. :-// There's a CDM-7SX191 monitor on eBay right now for $80... I've been meaning to get into one of these Chinesium video scan converters as a diag tool for a while, so that might still happen... but I think that if I were going to fix this scope, I'd prolly bite the bullet and buy that monitor. This of course is all dependent on how my dispute resolves out. ;) I wanted to spend a little time tinkering just to see if there were signs of life; I was hoping it might be easy to mod the CDM-7SF191 I have in that 54600A so it thinks it's a CDM-7SX191. I may instead try remoting into it over the RS-232 instead... in which case I'll soon be hunting down that software you posted and firing up the old WinXP Toughbook. >:D mnem :blah: --- End quote --- 8922M monitor info attached. The seem to share the same 15kHz / 60Hz rate as the 'scope ones so the resolution is down to the video generator not the monitor. The hardware in the older monitor is different but should be compatible. You are welcome to a monitor FOC but postage is likey to be far too high to make it worthwhile |

I am still not past COVID, but when I am back on my feet I can have a look. PN if interested pls. --- End quote --- I'm first and foremost happy that you are alive enough to post :D and second, I'm pretty picky about which kind of matrix I want.. It seems that the popular, easy chipsets are very governing in features; so that all boxes made the same time share the same limitations, at least for consumer units. A bit like the simple KVM-switches. I'm after a rather specific model, Extron DXP84, 2HE 8x4 or thereabout. With Ethernet remote control. There was one on ebay for ages that I missed because I kept putting the purchase off. There are more. I have them on my watch list. |

To get back into the TE mode I've got a few projects queued up...... Another one of the Type 1A1 plug-in's has gone funky on low mV ranges. That will involve jackassing a Type 547 on it's side to troubleshoot. Big fun. The capacitor adapters for the 465B PSU have arrived. The caps themselves should arrive Wednesday. After that going to start the electrical restoration of the tweaked chassis Type 547. And finally, just as a reminder...... "Down with the British" :-DD |
