The best (and addicting) part of repairing this stuff is the “it freaking works” moment. 😆

Hi, does anyone know if a Nubus card should show activity on the address/data lines if just power is applied to the card from a non working / running Mac logic board? I have a Radius Rocket card that’s not working and I was going to try to troubleshoot it but I can’t tell if Nubus cards need a...

So now that one board is repaired I am back at it with the original board that this thread was started on and I have a new discovery. I received a ROMinator today and when I put that in the board it came to life, although a sick life. With known good SIMMS I get one style of chime when I hit...

But when i put either card in my non working mac to troubleshoot (theres only power on the NuBus) neither card show activity other than a clock on the oscillator. trying to figure out how to troubleshoot the board(s)

Right and the accompanying software ScreenPlay sees the card too on launch (and then crashes). Thats the spigot card. The rocket is not showing up at all...

Btw. Any info on troubleshooting Nubus cards? It looks like if I just put a card in and power on a machine they don’t run there’s only a clock. Even the semi working video spigot (it shows up on a running machine in tattletech) doesn’t show activity on the roms or ram on a non running logic...

Ahh I beat you to the edit 😆 already bookmarked the page for download…

Top link?

eBay is getting out of control. Yellow Quadra 650’s on there for $300 plus $150 shipping 🤦‍♂️ The last one (re capped) sold for $600 plus $72 shipping!

No it’s the one from apple. “Apple Personal Diagnostics”… Oh and I ran MacEKG and Techtool on it

😂

The apple diagnostics software. I forget it’s name off hand. It runs a slew of tests. Cpu, sound, ram, harddrive, video….

That’s exactly why I ordered one. To bypass the ram test while I was trying to fox the board. No need for that anymore…

Just what I need to do. Buy another Mac! I currently have: 3 portables (1 restored 2 in bad shape) A Mac 512 A plus A PowerBook 180 that needs an lcd A PowerBook g3 lombard A PowerBook g3 Kanga (needs restoration / repair) A couple g5 and Mac pros in storage The IICX A few other more modern PPC...

I also have a Rominator on the way if that might help diagnose…

Yeah I was wondering the same. My original drive is on its last leg but there wasn’t anything worthwhile on it anyway. I’ve got a newly formatted second drive in it now and an external BlueSCSI. The logic board is passing diagnostics and disk doctor passed on the replacement drive. All...

Me neither, and I dont remember it from back in the early days.. the only difference with this machine now from then is I had a radius rocket card in it before so that woulda been an 040 processor. System 7.5.3 must have the thread manager built in since theres no extension and it fails there...

Lots... about 1.5GB on one and 10MB on the other

Found it after posting.. its a conflict with Apple Thread Manager. At least it is in system 7 my 7.5.3 doesn't have that though and it fails still there..

Anyone know what the cause of this "disk full" error I keep keep getting when 32 bit addressing is enabled to access my full 32MB of ram? Its a Mac IICX and certain programs cant save to disk.. They error out with a -34 Disk Full alert. so far the problem apps i've discovered are: THINK C -...
