  1. That’s the clip for the PowerPump to “inject” a higher clock speed (configurable in the Control Panel) into the stock crystal (via the Output Enable pin on the IC that the red clip attaches to). So you could just reattach both leads and still be OK. Or are you going to go without (33/66 MHz for the 040 and 601)?
  2. Yes, it can and has been done. Hence, the .bin file (yes, it's a ROM - ignore the file extensions) I linked you at the beginning of the thread when it took a turn towards JDW-ville (the ROM dougg3 created for olePigeon). And we know creating and appending a ROM .dsk image can be done, because bigmessowires has done so and documented it (based on previous work by Rob). I believe the current dilemma (if you want to call it that - or we can say "gap") is that we don't currently have the combination of the working ROM image with Turbo 040 patching WITH the ROM disk and there is no shortage of speculation why it doesn't just work. There's just a shortage of hired guns with the skill sets needed to dive in and work it out. From there we talked about the 601 and other enhancements like an in-ROM GUI/menu to load the images on-the-fly (à la Floppy Emu) but the above passage in bold is my assessment of where we/you are now.
  3. Macintosh IICi SuperMac video Card

    If it's like the two Thunder/24s and Spectrum/24 I have, then it's slightly different - you hold down Option past Happy Mac (even through the Welcome screen) and it should dump you to a black screen and start the cycle, and you would press the space bar to accept the current resolution/sync rate and reboot. Note, on my 950, sometimes the space bar doesn't register so be ready to just hit the reset key (from the inside of the case if you don't have the IIci key switches) just in case.
  4. This is weird - I could have sworn I replied but must have closed my browser before I actually submitted. But it would have gone something like this: Thanks for these links, @bigmessowires - I had a question about a passing comment you made on your programmer's product page. (https://www.bigmessowires.com/mac-rom-inator-ii/) On it, you said: Is this actually implemented somewhere or was that a suggestion of what the possibilities were by building some logic into the existing A/R/X boot menu?
  5. Weird - I won't rule out it's the PSU but it does boot with another MB installed (albeit with the ADB flakiness I describe above). But thanks for the observation - just goes to show the variability from one component to the next.
  6. Personally, if I had a choice of ONE effort to dedicate my time to, (getting the ROM disk working on the SIMM I have that's already working with the Turbo 040, versus working on Turbo 601 compatibility) I would take the latter but that's because I have two Turbo 601s... obviously, if I didn't, I'd be in the first camp. I'm out of town on travel this week with a little peace & quiet in the evenings so I'll gather everything I have and start a new thread, perhaps even including past posts (and they're out there) where folks talked about things like SE/30 + Turbo 601 but the thread went stale. With enough work dedicated to this project, I think it's be pretty cool to build a UI that, based on checked boxes, you could go through a workflow to build a burnable ROM file based on machine type (i.e., SE/30, Quadra 950), desired options, and bootable ROM disk contents. Basically what has been up to this point, but scripting what goes where (offsets) based on selected params and maybe even test it in Basilisk before writing to SIMM.
  7. 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 ROM disk. There is something in the ROM that serves as a disk driver and points to the correct offset where the IMG starts. (check out this link for details). With three small kids at home, I just haven't had the time to develop assembly programming skills but I'm sure it can be done... After all, if a "base" 32-bit clean ROM can boot off an embedded disk image, then it should just be a matter of figuring out if/how everything gets displaced with the 040 ROM added to the top of the stack. I own a programmer, a 4 MB ROM-inator II and an 8 MB MEGA. I bought the MEGA for the same reason you're considering it; to add additional apps, mostly for diagnostics and I wanted to at some point consider putting the A/UX MacPartition on it - the 4 MB version doesn't really have the space to add Disk Utility without doing some rearranging but I had a folder on a separate partition called "Copy Me to RAM Disk" that contained Disk Utility, Snooper, etc. that I could copy over and run once I booted from RAM Disk (another option the SIMM gives you) and with 128 MB RAM, I wasn't using that much memory for anything else. The MEGA is only what, $23 more than the 4 MB SIMM... so you may want to just go for it. I don't think the 4 MB is prohibitively expensive ($36) if you started with that and found yourself outgrowing it (just toss it in a IIci or even a Quadra 700/900 to disable the memory check) Btw - I don't mean to sound like an expert - I'm far from it - I only really started building my childhood collection last July but these are things I've learned along the way these last several months. As always, YMMV!
  8. 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. Weird! Looks like the board I'm used to seeing are 820-0331-A, made in 1991; the one I have is 820-0313-A, made in 1992. I'd assume this is just a newer revision, like the SE/30 w/ socket vs. soldered CPU? The seller states the board tested fine before he pulled the battery and it was put into storage (sealed in what appears to be a pink polyethylene bag) in 2002 and I have no reason not to believe him. Still expected to at least get chimes, even with no RAM. I'll try booting with my 700's PPC card to try and eliminate the 040 CPU socket. The seller has very graciously offered to send me a IIfx board (NIB service part!) to make up for it - sellers, that's how you make a situation right.
  9. 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 rudimentary grasp of the boot ROM process to know. Haven't tried that. It must be related to a CPU check during A/UX Startup (the 7.0.1 MacPartition boots up fine). What I once read on comp.unix.aux indicated that DayStar had A/UX compatibility on their to-do list but never got around to it. Not that it can't be done, in my opinion... DayStar didn't seem to envision their accelerators being used in SE/30 at all and look at us today. Tell me more?
  10. 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 and icon are pretty awesome). So give it a try with your programmer. Just make sure the SIMM capacity is correct and write to the entire thing. Now I'd really like to get one of my Turbo601s working. I have both the 66 MHz and 100 MHz models, the latter is in my IIci. It's also a bit of a bummer that, even though it's a full 68040, running basically on par (speed and computationally) with a Q950, I have to disable it to boot into A/UX. So there's two projects I'd love to have the skills to get lost in...
  11. 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 (8 GB) 128 MB RAM ("new" 30-pin all purchased from MemoryX.com) BMOW ROM-inator II SIMM w/ Turbo040 driver courtesy of @olePigeon Bolle's "short" PDS adapter Asanté MacCon SE/30 Daystar Digital Turbo040 @33 MHz On my wish list: Some soldering skills to put a right-angle adapter on my "tall" Bolle adapter so I can add my Pivot IIsi (or Pivot SE/30 but don't think that will fit) for external video A working ROM image to include what I have plus the ROM disk driver (so, 68000 assembly skills) I'm really hard-pressed to come up with anything else until one of the geniuses here builds that NuBus breakout box. I took the pics a couple of weeks ago... I could leave it on for hours on end (1-bit B&W but I prefer After Dark, Star Trek:TNG) but literally, in the last few days I'm getting a slow death chime and the Simasimac. I'm hoping it's just a loose RAM SIMM or the very-finicky ROM SIMM needs to be shimmed up again. I'm not too worried unless it's something crazy like the power supply or logic board fuse. If nothing else - I can look at the pictures and sigh! Thanks for letting me share! This particular SE/30 is in great physical shape with very little discoloring and is really my favorite.
  12. 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 as having 4 staples (L3 is the filter parked behind the ADB ports) I'm attaching some photos in case someone with better eyes sees anything obvious. The polyfuses (F3 in particular) look good/closed and I'm just not sure what else could have gone bad. Thanks! https://imgur.com/a/WzX3o3W
  13. 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 fast. Mouse requires 4-5 super-fast clicks to register as one double- video artifacts with NuBus video card; on-board seems to be OK replacement Apple Ethernet NuBus card (SONIC model w/ 68000 CPU) is recognized in Slot A but locks the system up when I try to select it in AppleTalk cpanel SCSI2SD with last good SD card image (taken Feb 2018 before issues) results in 0000000F major, 00000021 minor. Gray screen with ? mark as expected if I boot without SD inserted, but panics after I insert so maybe a bad disk driver (Lido, FWB, etc - I can't remember which one)? I booted from a physical HDD I used to have on my 700 before replacing it with a SCSI2SD. file copies, Snooper logic board tests, etc are super slow with ADB keyswitch set to ON. I left it overnight for a repeating test (including basic RAM 101010) and this morning the RAM test was only 10% or so done. Should have taken a couple of minutes. I took out everything but 128 MB RAM bought earlier this year from MemoryX. Quadra 950 board #2 Purchased on eBay two weeks ago - owner stated it was a working pull from a 950 with a damaged side panel in 2002, sealed in a bag ever since. Doesn't chime, even with no RAM installed, it should at least boot chime and death chime? No video, SCSI drive light blinks as I would expect would happen, part of the usual POST process I swapped out 68040s with my other 950. No obvious trace damage. Yesterday was the first opportunity to work with it. The "upper right" corner is cracked (i.e., the corner on the end by slot $E) but I checked and don't see any traces that would have been broken on either site. (just green space You may have seen this board on eBay, which I got specifically to replace the #1 above board. Now I have two I can't do much with. What the hell do I do? (PS, I'm inserting the obligatory "looking for a Pisces PDS card and internal caddy CD bezel" but would just be thrilled if I could get it working again - I promised it the PPC PDS card from my 700 if it cooperates with me) Thanks!
  14. Radius PrecisionColor 24XP ROM needed

    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!
  15. Radius PrecisionColor 24XP ROM needed

    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 Amazon), I would give it a try... might help me diagnose the the Q700 I'm still convinced got hosed by a bad 24x Would one of the $10 USB EEPROM programmers work well enough to dump my 24XP or do I need something else?
