It is, it just also has a pass through PDS slot which may be hard to make sense of in the photo. I can definitely hack some jumpers together to make the wiring simpler. Will put some more energy into it soon. Thanks for the info!

I got the Extron RGB-HDMI scaler. The box itself is outputting video. I have it routing to an Elgato HD60+ connected to a MacBook Pro. The MicroMac Lapis card is connected to a DB-9 to HD-15 adapter which is connected to a regular VGA cable which is connected to the Extron. The status...

Sweet, thanks!

While I wait for the power adapter to arrive, I’ve been reading through the manual. I see it scales to a bunch of different resolutions for output, but should it be capable of dealing with 64x870 input? If it’s connected to a normal TV or monitor, would the picture just have two huge black bars...

Did you set the nub on the large gear towards the front of the drive when you put it back together?

What disks are you attempting to boot with? The ✕ could mean you're using the wrong system file. Regarding the eject issue, did you already replace the eject gear? If so, it might be out of spec. Even some of the gears I've had printed by ShapeWays have been just enough out of whack to not...

@Trash80toG4 thanks for the tip. I ordered one from eBay to try.

Does anyone here have experience with the RGBtoHDMI? From the description, it sounds like it might help even if I need to make a new sync profile for it.

Maybe @PotatoFi 's ROM clips would do the trick for you? https://www.printables.com/model/35592-macintosh-se30-rom-clips

I'm nearing the end of building my dream vintage Mac repair shop. I thought it'd be fun to paint the interior walls Platinum gray so had some custom paint made. I used a CD-300 drive as a reference since it's painted metal instead of dyed plastic. The swatch in the photo has been painted, not...

FWIW I completely ignore categories now unless posting a new thread. I’ve been browsing with the What’s New link. Since there’s not a lot of activity I can just check the first few pages there and have a good sense of what’s happening. I agree there are just way too many categories though.

Pure nerd heaven moment right there. Congrats @Mac84 !!

Nice work!!

Thanks for letting me know. I'll follow up with the person from that twitter thread. Perhaps they got mixed up about what driver they used. There are a LOT of drivers for the various Lapis cards.

I messaged the person who created this Twitter thread showing a card with the same FPGA working with a VGA display. They recommended using the LapisColor / ProColorServer 8•16 LC driver available here with System 7.5. I set up a clean install of 7.5 and added that extension, but get the error...

I found the specs for the Ehman Full Page Display in the February 1991 issue of MacUser. It says 640x480 75Hz Vertical Scan and 68.85kHz Horizontal scan. That doesn't line up with what I measured on the card. Would out of spec caps have an impact on HSYNC/VSYNC on a display card?

An early 1991 ad for their two page display says 70Hz, but I haven't been able to find something similar for their Full Page Display.

@ScutBoy Thanks for the info. I found this ad for Ehman monitors in the December 1990 MacWorld which claims they had higher refresh rates than Apple or Radius, but don't specify what those rates are. Curious.

I've tried several of the Lapis (and Mobius) control panels posted to the archive sites in both System 6.0.8 and 7.1 and didn't achieve any better results. The Lapis Dual Screen 2.E control panel drives the card to output 640 X 870. HSYNC is 60kHz on DB-9 Pin 8 and VSYNC is 65Hz on DB-9 pin 9...

Thanks to a tip from @Zane Kaminski I've made some progress. I ended up taking out the logic board and running it from a SE with display so I could see what was going on. Installed the Lapis Dual Screen 2.E control panel. That control panel displayed a single option: 'Ehman Full Page Display'...
