  Just goes to show every single component, no matter how small, is important to the operation of the system. Really enjoyed this. Good work Adrian.

  Another museum quality device saved from the dump all thanks to newer technology and determined people like Adrian.

  When i was working at Computerland in the mid 80&apos;s, we sold some stupidly expensive monitors. &nbsp;They were intended for CAD use, and required a full length graphics card to run. &nbsp;They had 4 BNC connectors, one for each RGB color, and a synch cable. &nbsp;19&quot; CRT monitors with a crazy high (for the time) dot pitch.<br><br>Only sold a few, as the monitor alone was more than the computer you put it in. &nbsp;And don&apos;t get me started on the video card, it was almost as much as the monitor.<br><br>And that wasn&apos;t the worst part. &nbsp;You then needed an extremely high end plotter to get anything useful out of the system if you wanted hard copy. &nbsp;All this for a very early version of autocad, running on an IBM PC. &nbsp;Slow was the operative term here. &nbsp;But it sure looked pretty!

  Your crt content is some of my favourite! I&apos;m a crt maniac, it&apos;s probably my fave part of retro gaming and computing.

  I was a Radio Shack Computer Specialist during that era. The 2000 with monochrome was also used as our &quot;back office&quot; machine at that time, with a wide bed dot matrix printer. We &quot;MANUALLY&quot; entered all our daily sales tickets every night on that thing, no Point of Sale back then. I sold one Tandy 2000 to a local company with a CM-1, company was running AutoCAD on it and it was beautiful to behold. We sold a few others with custom database software to local Tribal (Reservation) offices. The 2000 was a beauty but not very PC compatible, before I left &quot;The Shack&quot; I bought a floor demo original Tandy 1000 with a CM-11, &nbsp;RAM board, and a 20MB hardcard. Still have the 1000 and your adventures have inspired me to haul it out of the basement next year. Maybe I&apos;ll dig out my Kingsquest disks, too, my son loved that game. BTW &quot;NTSC&quot; = Never The Same Color&quot; (old joke)

  The cheapest passive components can be a nightmare, as you discovered. You learned a valuable lesson in diagnosing analog circuitry. One of my EE professors always told us to check passive components first. He came from the old school of vacuum tube tech. He taught a elective course in vacuum tube theory and I am glad I took that course.
