Had another "Find of the Century" moment......
Went to this little hole in the wall computer surplus shop near where I work downtown. I decided to go there and see if they had any parts I needed, they did have quite a few things for some future stuff, but nothing I have an immediate want/need for. Then I found this......
1988 NEC MultiSync II JC-1402HMA 14" CRT
After finding a 486 in it's original configuration which the owner was sentimental about and had it sitting amongst for-sale stuff for god only knows what reason, I asked him "how much" for the monitor - he gave me the best price in the world - FREE!
It does work but it's going to need some repairs to the input board because the DB-9 connector is flaky. I can't get it to get rid of the colored hues depending on cable position, tried 2 cables, so the problem is definatley the DB-9, but reflowing/resoldering it 2-3 times now and little improvement other than a stable image has me thinking I will probalby need to desolder it, clean the traces, and put a new one on (time to go to Vetco). I'm going to replace that connector with something cleaner and newer.. Flexing either cable around thusly moving the connector causes the image to become clear and sometimes full color for a second or two, also, the cables feel loose into the back. Could also be a grounding issue too because I see some brown corrosion around where the screws attach the input board to it's sub-chassis.
Got the service manual from here, if's for UK Spec, but it works for mine to help with testing and disassembly, also works as the owners manual as well. - http://www.epanorama.net/sff/Computer/Monitor … ies_Monitor.pdf
I'm still shocked, it even has the original cable, and the 9-pin to 15-pin converter so it pretty much works with every PC in my house up to 640X480 res (actually 800X560 according to the service manual). Plus now my Tandy has a monitor.
