Thanks much for the input @trag

I'm right there with you, but concentrating on other wildly impractical avenues of approach to this mess for the time being. My CAD experience pretty much ended sometime in the mid-90's and never really progressed into the realm of 3D. I do 3D stuff betwixt the ears from 2D inputs. Works well...

I've always wondered how good those scanners actually are. Folks seem to use digital calipers, rulers and the like for such things. Thankfully, I have a sacrificial Luggable on hand. The retractable handle bits make that bezel seem crazy complicated to model. ;)

Hello Trash80toHP_Mini! The forum software will be upgraded weekend of 06/26. See this announcement thread for more information. :rolleyes:

I've been saying this for a while; what we really need is for a wizard of 3D CAD to recreate the LCD bezel of the Luggable. That way it can be printed with no Trackball cutouts for use with the NumPad or with a single cutout for left or right handed use with trackball and a larger display...

Carrier board development.

I was building a Hackintosh based on a 128K MoBo I got on the cheap from Shreve Systems. Snagged a NewLife accelerator that was supposed to be upgraded with TTL Video out. David at TekServe double-checked the board and my header soldering on the 68000. He said it was a very cool accelerator and...

If 1GHz Pi Zero 2 W won't handle remapping in real time with double buffered single frame delay, Compute Module 5 I/O Board in hand for 2.4GHZ injection. 1.5GHz Compute Module 4 and its I/O board currently reside in PowerBook 100 awaiting emulation to catch up with it. So it's available for...

BigPics will be thumbnailed later. They're easy for showing them to a Computer Science major at work. He's a whiz at Python. Comic book format pf pics and links make playtime for my noggin at work during downtime. ;)

Prototyping a data input capture board for the four VRAM chips on the FPD/SE in wire wrap. Remapping pixels in Pi Zero 2 W for output to obsolete LCD displays via HDMI->DVI adapter cable. Titans of FPGA have said the project seems 100% viable. Board is a precursor to implementation in FPGA. If...

I'm right there with you on wanting to display full screen on an SE, but with a catch. I need to go full screen from a Radius FPD Card in my SE in order to map the pixels as they load into VRAM. I'm wildly guessing your explorations might help, so will be reading closely. My goal may be...

Cobbling together obscure hardware into inscrutable configurations to accomplish things nobody expects to be worthwhile is what I do . . .

:ROFLMAO: Guess that's one way to find out if anyone's reading this comic book! See if you can figure out the layering plan for crazy VRAM data capture carrier board . . . done in wire wrap.
