Gonna get back to this one fairly soon, thought I'd post the pics today as they're somewhat relevant to a new project by vorg. https://tinkerdifferent.com/threads/the-macintosh-minus-pi-powered-mini-mac-plus-clone-with-5-crt-display.1833/post-16650

More pics and commentary to add later.

Anothe one exhumed from the crypt, pics went away in the original thread: https://68kmla.org/bb/index.php?threads/macintoshclassiciiicolortvp%E2%84%A2-hack.19802/

Panel shouldn't matter, we need that MultiSync Controller Board! ;) I'd have been happy had it only supported VGA and SVGA, 16" probably looks a bit nasty by comparison I'd think?

Lookin' good! Crazy notion for alternate to BackPaq camo: Knock the case back at the base and add feets to rest that cute little KBD upon in a Mini-Lisa3 config.:p

So it does support/scale 16" input? I need one! :love:

There's another table on p.17 where the footnote explains the discrepancy: Very interesting point you bring up about VRAM being reserved for TV/Video options. Frame buffering is quirky on those machines when it comes to what's in the TV-Tuner window. It comes up as an empty box when you do a...

No fear! That's fabulous, an autoscaling controller/panel combo for the Compact form factor is great news!

That'd be fabulous, but not very likely. If it's scaling 640x480 VGA, it'll likely scale 800x600 SVGA to 1024x768 XGA as well. Running that quarter panel slide show I suggested in GraphicConverter will tell the tale if you set images up for both resolutions.

Cool, but what do they represent according to the manual? Running off to work, so: https://68kmla.org/bb/index.php?threads/video-adapter-docs-scan-dump.24012/

You said the VGA Adapter setting was 1024/768, but were going to check that out. ;) There's almost always one switch setting that covers both 640x480 and 1024x768 @60Hz. There is usually one setting that covers anything thrown at it onto a MultiFreq Display. edit: can't imagine any other case...

It's not. ;)

Caffeine deprived WAG would be is that the panel's controller is scaling 640x480 VGA to fill the LCD's 1024x768 XGA field. If you had the adapter on the 630 it's more than likely set to handle VGA/SVGA at a minimum and VGA would be what you're seeing from the LCIII? Quick test would be to...

I think you need a bigger boat . . .🦈 https://everymac.com/monitors/apple/multiple_scan/specs/multiple_scan_15.html Multi Scan is not MultiSync AFAIK. Sounds like it's doing its best, but not very close given available pre-sets on that list. Something like a Dell UltraSync(?) LCD should be...

How'd that work running off an LCIII? The 630 tops out at 800 x 600 SVGA, 832 x 624 16" Mac in 8-bit and the LCIII lacks SVGA? edit: no board in that form factor supported 1024x768 until the 6360/6400 generation. Does that LCD support 640x480 VGA?

Loving it! That last CAD profile pic has me wondering if the limiting factor is not the CRT, but the Monitor's board? Don't wanna push too hard on the BackPaq notion, but it seems perfect to wrench your design into perfect or near perfect profile of the Mac Bucket using the extra cubic available...

Sounds like a plan. I'm wondering if a specific Radius Cable for running the Portrait was required? Lots of crazy cable models listed for different combinations in that Q$A Looking at the board you might find Radius using a sense line spell to weave multiple sync output magic for Radius vs...

ISTR someone explaining that "shimmer" in the Portrait has something to do with having a pair of CRTs on the same AC feed mucking somethingorother up? Dunno, when I put a sheet of galvanized steel between Radius TPD and Portrait sitting next to each other. I'd figured the problem was RFI and it...

I figured yours for the 75Hz version given that connector. No Apple of Radius Displays or VidCards that I know of used HD15/VGA Connector in that era. Thanks for the links, @mg.man If you have a multisync LCD, hook a Mac VGA adapter up to that backplane connector and have at it. I got the TPD...

If I had to bet a nickel on it, I'd say that's a standard DA15 Macintosh port for a cord with 13w3 at the other end for hooking it up to the Portrait Display as well as one Radius FPD or other.
