Ugg... sorry to hear! Were you building a GCR or MagicSac?

Correct. [AFAIK] 😀

AFAIK, yes. I *do* have an original - Adaptec even - card that "translates" ACSI to SCSI. I used it back when my GCR was new along with another card that "translated" SCSI to ST-506!! I ran 2 x 30Mb IBM ST-506 5 1/4" HDDs off the pair - with TOS and Mac partitions connected to my...

The "Mac" screen displays edge to edge of rhe monitor, the IIe display has borders. So I'm guessing the IIe "560x384" is just 'padded out all 'round.

Haven't had the chance / energy to do a full Total Replay / ProDos partition set up on the LC II, but I did connect my FloppyEMU in SmartPort HD mode with the bundled FE image from BMOW... No resolution switch... the output stays 640x480 @ 66.7Hz

Yeah. I've been exchanging PMs with @-SE40- throughout the day... pretty cool that his panel plays nice with 832x624. Given how small the disk icon is at that reg... imagine what it'd be like at 1024x768! Sadly, though, that panel he has seems to be unobtanium... I've not been able to...

I don't have anything on the LCII to load atm... must get the TotalReplay image...

Just remembered... the "LC" supports 512x384... I do have a LC, but not sure I have a working CRT that will work at that rez (don't think my LCD will?). I'll see if I can explore that path...

OK, so... on my LC II, when running in IIe mode, the resolution is NOT changed - the LC II keeps the output at 640x480 @ 67hz. So "switching" seems to be a "CC" phenomena?

Stay tuned... will let you know what I find. Also curious to hear from the gurus States-side once they're :coffee:'d up and online... :LOL:

there's 'bootstrap' code in the form of MacWorks by Sun Remarketing. Perhaps that 'patches' the underlying ROM functions to add the Lisa resolution? Do you mean CC? Regardless, I'm now curious what happens when going from LC 640x480 to "IIe" mode [560x384?] with an external monitor - esp. a...

I don't think it's "required", more 'designed-for'. Example, you can run MacOS on a Lisa - but it looks a little odd because the Lisa does not natively have "square" pixels. For the Macintosh XL, there was a "square pixel" mod to correct this. My point is, it should 'work', but it may not...

Cool, THANKS for those! I was wondering about the LC. I do have a IIe card in my CC II, and I do have a LC575 'board, so have been toying with doing the VGA mod. Good to know I won't lose IIe capability. I'm still curious as to whether or not MacOS could access this 560x384 mode without...

That begs an interesting question... if you're correct that the Apple IIe card forces 560x384, then that would mean it's "boosting" the resolution of a stock CC. Are you sure it's not just a case of the CC analog board having the ability to sync on the 'lower' Apple IIe resolution? How have you...

...or what about going to 560x384 in "Mac" mode? That might be more doable - since the h/w has been modded for 640x480? I assume the Apple IIe mode is stable with the VGA mod in place?

I've asked @-SE40- to try the 832x624 switch combo and report back. Will be interesting to see if there some Mac resolution support in his flat panel circuitry - I would not be totally surprised, though the resulting image may not look great! What's bugging me most, however, is why the '630...

Hey folks... spawning this query off from the discussion over on @-SE40- 's Takky Mac thread : https://tinkerdifferent.com/threads/a-takky-mac.1363/ According to multiple sources - including https://everymac.com/systems/apple/mac_performa/specs/mac_performa_630.html - the Performa 630 has 1Mb...

It'd be worth trying 2, 4, 5, 8 - which is 832×624 = the highest resolution the '630 on-board video supports. See if your panel will sync on that.

Hate to burst the bubble... but I believe you have one of these: ...and if so, the answer is on the other side: 3, 4, 5, 8 = 640x480 I'm afraid.
