Hi, @JDW - Check my comment, the 4th one above yours and you'll see the ROM link (which I PM'ed you as well). I alluded to the challenge in building a custom ROM AND a custom bootable disk image. I found it's not as simple as concatenating the ROM + the disk .IMG and ta-da! You have a bootable...

Just noticed that the replacement 950 board (#2 above): 1) has black RAM SIMM slots instead of white (still 16 across 4 banks) - I'm sure this is very common in a typical supply chain. 2) doesn't have a ROM SIMM slot at J7; rather, it's got what looks like 64-pin pads for soldering on a slot...

Sorry. I thought I read in another thread that you had a programmer - or maybe you just have the ROM-inator II SIMM itself. I'm not sure the ROM image bypasses anything on the 040 card; rather, maybe it rearranges to whatever the accelerator expects to see before patching but I don't have even a...

Yes, it's 32-bit clean. Here is the ROM image (thanks again to OlePigeon): olePigeonPatchedROM-normalchecksum_disabled.bin - so it's the 040 driver, memory test disabled and some other features that you won't see with the accelerator installed (again courtesy of OlePigeon - his custom boot chime...

Since I am not too shy about asking for help with my myriad Quadra issues, one of the things that has been going great is my SE/30 (edit - until last week!) Here's my setup: SE/30 recapped running System 7.5.3, Mac OS 8.1 and A/UX 3.1.1 (the latter requires me to disable the 040 card) SCSI2SD...

Thanks for the links, @trag and @CC_333. There's not a whole lot of Iici-specific content in the last link to the Pina Mac II book and even less for troubleshooting ADB, but it seems like I'll want to check out the 4-pin EMI RFI board filters that I think are the black cubes with what I describe...

Hi, Me again - I was the guy having issues with my 950's ADB port/video artifacts and SCSI2SD booting/Sad Mac: Quadra 950 board #1 The issues could be described as: (just in case y'all have any more ideas) ADB is on crack. Text carat blinks super-fast, repeats almost instantly and equally as...

Wanted to edit my above post but too much time has passed.. This is 100% Bolle's thread. I didn't mean to appear as if I was hijacking it - I am more than willing to dump my 24XP ROM to help provide another data point (the cards arrived today). Sorry!

I just bought a PrecisionColor 24xp AND a Spectrum/24 Series IV. I feel like I got a better deal on the former than the latter but the Radius looks identical to Bolle's (ROM v1.3.2). I don't have the equipment to dump but if there's a cheap way to do it (there's a ton of USB programmers on...

I'll throw this out there even though I'm not 100% positive it's still relevant: I would be willing to at least loan out my nonfunctional Q700 board (the one that spawned this thread) or would outright donate it to science to help further this cause. It's not doing anything for me right now and...

Thanks for the candor, everyone. As a last-ditch measure, I installed the Easy Access cpanel onto my 7.6.1 partition on my working Q700 and tested Mouse Keys by (IIRC) Shift-Opt-Cmd-Clear... on the bad Q700 I can enable Mouse Keys (the up-sliding beep) and can use '5' on the numpad to click but...

Thanks for the info. There were a lot of Moto chips on it when I had it open over the weekend. I keep bringing up TechTool because the Zap from within the app fixed a previous issue I had with this video card (which, back then, only caused a problem with booting, not ADB)... an issue that...

OK - so, along that train of thought... Recall the original issue was due to a bad or flaky Radius PrecisionColor 24 that freaked out the minute I changed resolution or bit depth... Let's say something got messed up in PRAM that couldn't be cleared by pulling the battery or zapping (which is...

Will be happy to pull mine out of the closet and let you know if they’re implemented. PM me if I forget to get back to you this weekend :) Is it giving you any trouble? 

Echoed. Would like to see examples of label placement, especially with a DayStar 040 or PPC 601 installed (even the Floppy Emu - great touch!). Whichever machine I decide to put my Stage II into later today will look like a NASCAR Chevy :) I've only placed one decal on a machine and it was a...

Ahh, brain melting... But seriously, thanks for the link. Could a bad clock driver allow the machine to operate normally, with the exception of certain input registers like mouse movement? It seems this particular chip has a fmax (Maximum Clock Frequency) of 70 MHz, so the chipped 66 MHz...

Certainly, @trag and @powermax: It's a Motorola XAA204, p/n FB03. Below is a picture from my other Q700, which I had in front of me at that momen. I was wrong in a previous post, the red claw connects to pin 7 of this chip, not pin 1 (judging by the orientation, marking and drawing).

So I found a possible CAUSE that might lay out next steps? I have (or I should say had) an Apple Ethernet NuBus card (with the onboard 68000) and was happy with the improvement in performance. I just now remembered moving cards around in the 950 (because I wanted to test out a 601 PDS card that...

Bumping this in case anyone else has ideas... I worked around the issue by acquiring another Q700 but I would like to get this one working... it does have a 66 MHz crystal so the 040 and 601 PDS card run ~30% faster than stock.  Another theory - does anyone know what IC chip U54 does? It's...

Bragging rights are good enough for me :) The machine in which it would make the most sense to use the Rocket is my Iici, but it already has a Turbo 601 so I think it'll go in my 950 until I can acquire a IIfx. I don't have the SCSI daughtercard for it but I'd be perfectly content to have a...
