By "for at least part of the summer", are you saying that you're just going to have that computer until fall, and then get rid of it? Or does it just mean you spent some of the summer getting it to work? It is neat, though.
At least part of the summer in play around with it, if not all summer, then I'm likely putting the NEC Ready up on the desk to set it all up and load it with programs. What I've been doing is switching my retro rigs out on rotation. I ran the 486 all year last year, but as of this spring I ran the GEM 286 for awhile, then decided to break out the Tandy, give the Micron SVGA monitor a break, and use the NEC MultiSync II and the Tandy for awhile.
I'm not getting rid of it by a long shot, actually I'm using the Tandy to start breadboarding up a light pen for it since I got the hardware reference manuals and all that for it, I got something close working using a light sensors and a resistor but it did not actually "work work" (seemed the CGA chipset saw it for a second and moved the cursor there) - thinking about using a phototransistor from a USB Optical Mouse instead (then I can make using one Optical mouse). The wiring is pretty simple, just the first four pins of the DB9 - +5VDC, Light-Pen Data, GND, Button Data - and it only uses the emitter and collector of the Phototransistor. The base is not used.
Other future upgrades - though maybe not this year
- Overclocking board, my own design or copied booster interposter of some kind.
- Color Mouse or Deluxe Mouse
I've also been looking at 8-bit guy's Planet X 3, I've not bought a DOS game in a long time but that one looks like an awesome candidate for the Tandy.
🤣, actually that's because I posted the photo from my phone, a google Pixel 3, and it was being a bit silly. If you click on it it'll give a decent closeup high res photo.
