If you look here you can see my PET 2001 motherboard in a suitcase. http://web.mac.com/lord_philip/other_computers/20012.html#107 It was the perfect fit, and I even have a 'PETdisk installed now. I don't consider this project complete yet as I want to tidy up the cabling that brings the power into the case for a more elegant solution, and finally I want to install an internal 7" LCD monitor/TV as I have a couple that I purchased a few years ago on a trip to China for about $50 each. I have measured things up and if i build a small bracket I can mount the screen on the lid of the case (inside of course) and have it 'float' above the lower left side of the motherboard. When closed it should fit snugly behind the keyboard area. Ultimately I want it to be a all in one unit that I can take to parties and impress the hipster crowd (ok, only joking about that). I have one of the composite adaptors from eBay and I find it to work very well with the LCD screens.

It also doesn't have the large capacitors and heat sink that the other pet boards do. As a bonus it runs off +5V. An 8296 motherboard (no "D") can also be converted easily. These motherboard would fit nicely behind a 15" lcd monitor and also have the external keyboard connector. I wouldn't want to use the "SK" keyboard though since it would look strange, and instead try to mount the keyboard in a smaller enclosure. > > VICE? .... smack! didn't duck fast enough ;-) > > Steve > From: MikeS <email@example.com> > To: firstname.lastname@example.org > Sent: Tuesday, May 8, 2012 8:10:41 PM > Subject: Anyone ever attach a mono LCD to a PET? > > > > One of my back burner projects has long been using an old terminal for the > > P/S, display & case, and maybe even the keyboard; unfortunately the PET > > boards are a little long to fit inside any terminals or monitors that I've > > seen so it'd probably need to go into a pizza-box case under the monitor. > > > > Just another option... > > > > But heck, anybody can hook it up to an LCD; what you really need is a nice > > plasma screen; maybe squeeze it into an old Toshiba laptop?
