IIfx Won't boot — #85
As for the jumpers (partially documented here), J106 is open, J103 is closed. This seems to be the correct setup.

That is a great find. Nice to know. I tri…

IIfx Won't boot — #84
I read back over the start of this thread again. Just wanted to add some pieces of info.
I too have two different brands of RAM. 4x Texas Instruments and 4x Accutek. I've tried ea…

The screen takes a bit of time to kick in, so it's possible that the SuperMac logo appears before the grey screen with the other drives. By the time the screen is visible the logo …

The SuperMac image is resident in the firmware for the video card. That is, it lives on the EEPROM chip on the video card.
If you're not getting that screen with some configurati…

I took out the RAM and ROM and cleaned the contacts on them with q-tips and isopropyl alcohol. Still no improvement. The RAM slots are in two banks of four. If I leave two slots em…

I'm still a bit confused by this claim that active terminating drives don't need special termination on the IIfx. The dead IIfx hard disk is the only one that when connected up to …

Last test for tonight. I put my 7500 hard disk in the LC III, wiped it and installed a fresh System 7.5 for all Macs (I tried 7.1 but the resulting install wouldn't boot the LC III…

On the 7500 the hard disk was on the end of the cable with the cdrom as intermediate.
You're right. I assumed the term jumper would be at the back. I took off the drive sled and t…

Okay, they don't have any jumpers, but does that mean that they don't have any jumper pins? I've never seen a SCSI drive without jumper pins (or resistor packs) to set the termina…

Ran out of edit time on the last post.
Using the 7500's jumper-less hard disk and cdrom I get the grey screen with term power enabled or disabled on the cdrom.

Thanks for the ideas.
I'm pretty sure I tried with no scsi cable attached and got the grey screen. I'll try it again soon and see what happens (I have it sitting with batteries ou…

I just tried the hard disk from my Classic II but it still won't go past the grey screen (no rounded edges btw). So that's power ok and known-good HD not booting it. I've tried the…

A friend called over earlier with a multimeter and the PSU checks out. +12v, -12v and +5v in all the right places. The batteries checked out too.
I just tried the hard disk from m…

Unfortunately no. I'm not really equipped for this level of troubleshooting. I'm still at the swap-with-a-known-good-part stage.
I've stripped it down a bit now. Disconnected ever…

Still no progress. I can't get it to boot beyond these grey screens. I've tried the internal disk from my 7500 and an external SCSI (as apparently you don't need the black terminat…

Instead of starting a new thread I'll tack onto this one.
I'm trying to get my "new" IIfx working here. Initially it didn't power on. I added in two batteries and that got it to b…

I can't commit to putting lots of time into this. I can look into an extension or whatever for possible tables, but doing ROM hacking in't something I have time for.

I'm terrible at pattern finding, BTW, but an ace at finding pattern disruptions . . . picture the sort of guy who can find a four leaf clover just about anywhere without too much f…

Hmmm, even if there is no extension with the driver, it still could be possible to patch the driver in memory. So the process might be an extension that finds it in memory, patches…

The basic drivers are in the DeclROM for Sense Line defined/activated FixedRez Apple Monitor standards.
IIRC, the RadiusWare control Panel would be where any "options" were set fo…

No, unfortunately I don't have much hardware tools beyond a digital multimeter and anything custom I make on a breadboard.
Using a ROM might be too difficult. Regardless, the idea…

I'm not at home, so I can't upload the driver but . . .

Maybe. It depends on whether the resolutions are hard-coded into its driver ROM, or are in an extension that can be modified. For the built-in driver for the PM8500, I had to figur…

Just out of curiosity, do you think there would be any way to hack the driver for the old Radius Color Pivot II Cards to put out a 60 Hz resolution for use with modern LCDs?
