  1. A makeover of the 5120 board will be awesome when you get enough time for the project. In the meantime, what I'd like to see you play around with would be a generic interface board for the LCD. Then Bolle's SE/30 board could be adapted to fit the Portable form factor using the 12V input ATX power supply developed for the LC? No longer battery Portable, but lots of fun to be had with existing building blocks while you work out a way to knit together the 5120's proprietary parts? Rebuilding those will be crazy complicated, no? Following your topic closely, I like your notio
  2. The PDS connection should pry apart easily using just your fingers on the SE. Doing it gently/firmly at both ends alternately where the board mounting flanges are located should do the trick. You'll mostly touching the circuit boards. Some connectors have shallow grooves for twisting a screwdriver on the sides.
  3. Might could be, but the only thing that'll get me into Tiger/Classic will be Final Cut Studio and I haven't gotten around to loading, much less playing with Final Cut Pro in OS9. I've finally found a 27" 1440p Panel that supports 1920x1200. It's more than I'd like to spend, but it'll dangle my toes in the deep end of the pixel pool.
  4. Very very nice! Might I suggest adding a straight row of headers duplicating the connector on the board. Female to female jumper wires could then be color coding matched row to row for those without proper cables. The PCB would then be useful for any proprietary iteration of DE9 or even the CoAx connection on Radius Cards. There's a bare Radius FPD card on eBay ATM that could use such a board.
  5. Very interesting, I'll have to check that out in the docs. Wondering which PCI bridge they used in the BG3s, maybe the same bridge as the 6400/6500? The third PCI slot would be where that function wound up if it that happens to be the case? I'll check my NICs to see if they match your list or not. Great work @chelseayr
  6. Should be simple enough to design a breakout board PCB with VGA HD15 connector mounted to the original backplane cover plate.
  7. I wonder if the virtual desktop(?) will ever make a return. Imagine pulling around a massive CAD drawing or artwork free of screen redraws. The 4K window into the page could be as small ss that "About this Macintosh" window. Probably not necessary given screen updates of current graphics tech, but it might be a way to explore a 3D world without any disorientation at all?
  8. Thanks, I'll have to take a look at the docs on my Extron Scaler. So far I've put a couple of oddball expansion card resolutions at 1:1 on my 1080p TV with great results. I'll have to see if it or a newer version will do the same for 1:1 WUXGA in a window on a 1440p display? Still hoping to find one with pre-set support for WUXGA though.
  9. Can't be the aspect ratio, given the variety of what I've seen in every manual I've searched? What gives? A 27" 1440p display that can do a 1:1 1920x1200 WUXGA window the size of a 24" panel would suit my needs just fine. But I've not seen anything available from any manufacturer as yet. Does anyone know of one? It seems silly to me that the list of crazy old time displays/aspect ratios goes from 640x480 VGA up to that awful "Full HD" excuse for a desktop resolution and then jumps straight to 1440p? Skipping over the only halfway workable desktop resolution in between seems t
  10. Found an interesting pic for comparison in your other thread: The cutout in the foam looks to be the size of the standard spec. SE card above. The vacant cubic looks remarkably like a compact NIC footprint? Could be for a VRAM expansion card for a huge virtual desktop setup as well. Curiouser and curiouser . . .
  11. There's a pic above of the way I got my Radius TPD up and running on the BNC inputs of my 21" CRT. That will likely work on a VGA cable as well I'd think. Syncing display properly to the card's signal will be the major hurdle.
  12. Yep, side view required. PCB real estate conservation and straight line bus trace implementation would be the reasons for that IC packaging. https://en.wikipedia.org/wiki/Zig-zag_in-line_package Not all that important or readily apparent in single bit graphic card implementations, but for 24bit color in the NuBus era it was a big advantage. Corn row upon corn row of those VRAM packages can be seen spaced tightly with straight line trace connections on the likes of TRUEVISION NuVista cards. Staggering pins on the ICs instead of traces on the PCB as required
  13. I see four VRAM packages on that card. What do the specs on the ICs say, I'm curious about capacity? What's really interesting to me is the expansion header on the left side. We've seen similar connectors at the rear of accelerators for VidCard installation. Wondering about ThinNet on the Co-Ax connector? Buzz the center connection to see if it might wander over to a pin on that the expansion header without interacting with the VidCard maybe? It's most likely an alternate video signal over that connection to a different monitor interface. Radius TPD uses a Micro Co-Axial connector
  14. Was wondering how well tiling 4x1080p for a seamless desktop might work out on that $1,600 4K screen. Took a look around Amazon for stacking a quartet of 1080p screens for a budget version that's deliberately imperfect. Came up with what might be a workable solution for .5 bazillion pixels in the short term that wouldn't dwarf my workstation or sink my budget. _____________________________________________________________________________ | | || | | | |
