My friend Dave is both a god of both graphics and avian photography.\u00a0 He’ll be writing the software that will show the various screens on the AWG-20 PACS or Programmable Armament Control Set (also known as the MPCD or Multi-Purpose Color Display)<\/p>\n

Below is a test display he wrote for me and I’ve put my “spare” MPCD button collar frame around it so you can understand what it’s all about. \ud83d\ude42<\/p>\n

I rebuilt the MPCD that I have with a 7″ monochrome green VGA monitor.\u00a0 Within a couple of months of that feat (it’s not easy shoe-horning a “standard” CRT into the original enclosure!) I discovered that the MPCD is a COLOR display.\u00a0 Cue facepalm<\/strong><\/em>.<\/p>\n

You cannot buy a 7″ color VGA display for any amount of money.\u00a0 I’ve tried.\u00a0 Repeatedly.\u00a0 For five years.\u00a0 The original display is a 5″x5″ color vector tube and while I could find a replacement, they wanted $5000.00.\u00a0 EACH.\u00a0 Cue 2nd facepalm<\/strong>.<\/p>\n

I finally found a 6.4″ LCD kit from Earth LCD<\/a> to the tune of $350.\u00a0 Painful, but no where near the pain of the original.<\/p>\n

So what I’m doing is replacing a 1:1 aspect ratio display with a 4:3 aspect ratio display that “mostly” fits.\u00a0 The important part of the real estate that the LCD covers is the 20 buttons that surround the frame.\u00a0 With a little adjustment, it properly covers all the space that they “occupy” on the screen.\u00a0 I’m going to place a layer of 1\/16″ or 1\/8″ smoked plexiglass between the LCD and the MPCD button collar.\u00a0 When the unit is enclosed, no light will enter from the back and you won’t notice there’s a huge air gap above and below the LCD.<\/p>\n

The original display had a resolution of 512×512.\u00a0 At 640×480, I’ll have the width I need, but I’ll be short 32 pixels (shy 16 at the top and 16 at the bottom for all practical purposes).\u00a0 This will make things a bit tight – there are some MPCD pages that are pretty dense, but I’m sure we’ll get it figured out.<\/p>\n","protected":false},"excerpt":{"rendered":"
