After trying everything, replacing the F258 chips solved the simasimac/death chimes issues I had on my first SE/30. It always chimed, though.

Oh, interesting! I didn’t know about such thing. Will look it up! Honestly, I haven’t tried the other way around. Only verified ground and made sure the black cable from the LED connected to it. Should be correct but I guess I need to try…

Anyone else using a PiSCSI/RaSCSI mounted internally, powered by the Mac? Two things: the shutdown process. When I shutdown the Mac, the RPi will also turn off, abruptly, and possibly corrupt the SD card. If I shutdown the Pi first, while the Mac is running, the Mac will freeze. What’s best...

Since my last post I've put this project aside for the moment. Summery of what I've done: • Replaced all caps on the logic board • Adjusted the voltage rails on the analog board • Changed to another pair of RAM modules — computer now actually started to boot normally, but with intermittent...

The results were quite interesting! Some games crash, some errors a lot, but a few actually seem to work! At least the beginning of the games. Police Quest 1.50 normally has some graphical glitches at the first scene, movement of the character isn't visible in som areas. But after I dropped all...

Yeah Mini vMac works, but like mentioned I also have my SE/30, which is old enough for the games to run properly. I was just playing around with the idea of putting an older ROM in the IIci.

Aha, too bad! Then I guess my “just disable QuickDraw in ROM hack” approach might be a bit over simplified too.. :)

Sorry, it's the all the old AGI games. 2.x versions does seem to work on newer machine, but they don't exist out there on the interweb, only the older 1.x versions. Here's an interesting write up someone did about these old games...

Yep, they run, but very glitchy. Only way for me to play them is on my SE/30, with it's "dirty" ROM + color card and monitor. But I'd prefer to run them on my IIci instead.

Looking at the disassembled IIsi ROM (used by the Mac ROM-Inator II) at https://mac68k.info/repo/rom_disasm/IIsi/, I see a few QuickDraw references (I think): QDExist, ColorQD, NoCQD. And that's where my ROM hacking knowledge ends. :)

For the Sierra games to work you mean? The issue is 32 bit QuickDraw — which is included on all clean ROMs, switching to 24 bit addressing has no effect, unfortunately. Edit: I wonder if it’d be possible to program a PurpleROM with a stock IIci ROM, but exclude 32 bit QuickDraw?

How compatible are the Macintosh II ROMs with each other? I don’t want the IIci ROM to be 32 bit clean — so that I can play all those old Sierra games in color without issues. I’ve tried to run it with two different SE/30 ROMs, but it doesn’t work and the machine just starts with chimes of death...

I just tried your driver and when installed the only interface I can choose in Network and MacTCP is LocalTalk. I also tried the DaynaPORT drivers but with them I have the same issue as with the Shiva drivers. So I guess the card/transceiver is faulty...

My Classic II had the same issue just recently. After I did some cleaning and re-soldering of th Egret chip on the LB it suddenly came to life again.

Thank you for your advise. I had an old Airport Express with 10/100 ethernet lying around, I'm now using it as a bridge. Tried this just now. Installed a clean "IIci" installation of System 7.1. Then NSI 1.5.1, and then the Shiva/Kinetics/Novel drivers. I can see the "EtherTalk" device in...
