68kMLA Classic Interface

The card is in a Quadra 950 (it has 486SX on board), PC Setup 1.6.4 is installed on both Mac OS 7.6.1 and 8.0. When I start the PC in PC Setup, it only says “PC is booting”… and hangs in the booting stage. Switching to PC mode fades the screen to black and it remains black until I switch back with the hotkey combo. Tries with 2 different monitors (one apple 1212 CRT and a Samsung TFT), same happened. I reseated the 486 CPU and the RAM as well. What can be the issue? Where can I download PC Setup 1.01 or 1.5? Would that maybe help?

Is the extension blue or black while the Mac is booting?

Weird, I fixed one of these once just by reseating the CPU and repasting it... That was all. Felt like a cheat... Especially as someone shipped it across the Atlantic to me.

No help with my reply but to tell you that I have the same behavior on my 6100/66 DOS … sometimes 🤪
Sometimes it works then sometimes it freeze 😕

This is how it looks like while booting:

Reseating and repasting didn't help 🙁

Some people told me it can be an issue with the monitor. I have an Apple M1212 CRT, and a Samsung TFT with an adapter (with those DIP switches). Can it be a problem that the DOS card is not recognizing the monitor, and that's why it doesn't boot up? Maybe with a compatible Apple monitor it wold work?

The icon should look like this :

I downloaded PC Setup 1.6.4 from MR. (screenshot in my earlier post) Can you please drop me a link where I can find the proper version?

It was s floppy image, I mounted it with floppy emu, and just ran the installer. I didn't copy any files manually. Should I have done that?

The reason I ask, is your photo shows the PC Setup control panel running from your desktop? It's meant to be in Control Panels of the active System Folder.

If you have it on your desktop, that explains why it isn't loading during boot, and also why it isn't working.

View attachment 68781Oh I see! It was in the control panels, I just pulled it out for the photo 🙂

After putting it back and restarting, this is what I see at the start screen. First a lot of icons are coming, then all those are disappearing, and only the C> icon comes... What does this mean? 🙂

That's good 🙂 it is able to talk to the card. Have you tried starting the card now?

Yes, I tried. Same result... Booting forever, and if switching to PC mode, only blank screen after the fade out... Now I am installing Mac OS 8.1, and give a try there... Maybe a fresh install helps. Maybe...

Which Mac OS do you recommend for this DOS card on the Quadra 950?

I just wish it would work sometimes. Mine never boots, just keeps saying "booting"...

I don't think 8.1 will help.II think I have it on 7.6.1? I forget. Not 8.1 anyway

Remove the RAM SIMM for now. It isn't absolutely required. Try without it.

How do you have the cables wired in? What disk image are you using it with?

Once mine turn "black", it does it until next Mac reboot. :-/

Also, my 6100 is connected to a LCD monitor using an official dip-switch-less Apple DB15 -> VGA adapter and it does not like PC's resolution.
My monitor says that I should use another resolution (even if it can display PC's one) until it switches off by itself. Playing to digger it a pain with that setting.
I have to try with a dip-switch adapter to force the resolution to check if this can change the behaviour.

One question ... how do you connect your monitor to the DOS card ? 🤔
Are you using the infamous octopuss cable that came with it ?

Regarding image: I downloaded the file called "PC-Setup-FloppyEmu-Images.zip" from MR, and used that one.
