    how to remove cpu from Quadra 840 AV

    I have a special pry bar that came with a 68040-50 upgrade for my Q950. Very strong flat thin metal slightly curved at the end with teeth that fit in between the pins so it is easy to pop a CPU out without bending a pin.

    iMac G4 won't eject CD/DVD drive!

    It could be the IDE cable I would think it would be the drive's power cable. Is they a manual eject?

    SE/30 video redraw problem

    Check the CPU address lines to the muxes UA8-UD8. Most of the time one of them is broken.

    SE/30 video redraw problem

    Thanks guys very helpful. I traced D24-D31 back to the ROM and PDS slot, everything fine there. Also fine were RA0-8 and the other lines RAS/CAS, etc back to the PAL ICs. Were there any others I should check? Unless there is something else - then I guess either the 253 mux’s or a bad PAL. Are PAL ICs known to die? Long shot but there a reliable source for replacements? seems unlikely 30+ years later anyone Is burning fresh ones... Further info, my board is p/n 820-0260-10. It looks like an early revision as it has a factory cut trace to UI6. PALs are marked: UE6 341-0637-A 918NNDKB UE7 341-0688-A 918YZLAB UG6 341-0635-A 921ZIMOB UG7 341-0633-A 918NLTJB UI6 341-0665-A 917NJFCB

    SE/30 Xceed greyscale adapter cloning thread

    I searched "xceed" in the MacUser archive from January 1989 thru January 1991 w/o finding a single peep about internal grayscale. Until that point they appear to have been selling inexpensive, unaccelerated SE/30 PDS cards for external 640x480 and 1024x768 displays alongside a lineup of NuBus cards so uninspiring as to be entirely missing from LEM's NuBus Video Card page. Micron started advertising Xceed Memory Upgrade Kits in the MacUser August 1989 issue and began advertising VidCards in the November issue of that year. Things stayed pretty much the same until they listed a NuBus Card capable of 1152x870 in their November 1990 MacUser ad. It'll be interesting to find the SE/30 Internal Grayscale announcement or a review of any of their cards. BTW, it would seem Micron is still rolling right along in the memory business out in Boise. Crucial is one of their trade names. I wonder if anyone has been working there for thirty-odd years?
  7. I did not, but that would have been a good idea! Thanks.
  8. So just to update, I'm still having no luck with this card. I've tried multiple permutations of the cuda button/processor swap, cleaned the card's contacts, put in a brand new PRAM battery, tried re-installing the sonnet drivers over a brand new install of 9.1, removed the factory L2 cache from the cache slot, went down to a single matched pair of RAM, and still nothing. I even tried it in my parts 7300 (which it worked in back in 2008) just to rule out issues with this logic board. I think at this point I've ruled out everything but pining for the fjords.

    how to remove cpu from Quadra 840 AV

    I use a 1.5” chisel and slowly lift a little each side, going around three or four times. The pins might bend but not if you do it bit by bit all around. If they do bend, just bend em back. Very easily done. I don’t think I’d try it with a screwdriver, though.

    how to remove cpu from Quadra 840 AV

    Here's a thread that shows the empty socket. The CPU has to carefully come straight up to avoid bending/breaking any pins. Why to you want to remove the CPU?

  13. Did you try going back in time?
  14. Hmm, I’m not sure what the answer to that is, but how has battery life been? Also, what version of Coconut Battery are you using? I haven’t been able to find a place to download one that is compatible with Tiger.

    Yup. Screen printed Pantone colors. Don't recall the numbers in my head... Edit: here they are:
  16. Hello, Can someone kindly tell me how to take out the CPU out of a Quadra 840 AV? I was able to take off the heat sync, but I don't see any kind of lever or button to press to release the CPU from the board. The service manual didn't mention anything on removing the cpu either. Do I just pry it out with a flat head screw driver? That just seems dangerous lol. Any advice would be greatly appreciated. Thank you!

    SE/30 Xceed greyscale adapter cloning thread

    Interesting: https://vintageapple.org/macbooks/pdf/Micron_Technology_Xceed_SE-3010-78_1989.pdf So the SE/30 3010-78 supports 1024x768? What's the timeline of Micron Technology's 030 PDS product lineup? Which models support internal grayscale and which don't?

    My dad goes to Geneva a LOT for his IEEE meetings. It's expansive as f**k. Except the cheeses. He buys a bunch of cheese at the duty free store since he's technically an ambassador for the U.S. while he's there on IEEE businesses. Swiss chavroux is the nectar of the gods!
  19. I just bought a Mac Classic II that had a checkerboard pattern, so understand there is some re-capping work ahead of me. I inspected the logic board so far and it seems fine - will be reviewing the analog board soon. Is the checkerboard pattern a result of bad caps on the analog board or is that more the logic board? Both will need to be re-capped but I was hoping to focus on the analog board first because the caps are bigger/easier to replace, so am hoping the checkerboard issue is resolved by that - can someone confirm? Also, I tried turning the computer on/off a few times to test it overall and it seems the monitor will exhibit "half" brightness levels as shown in the two screenshots below - one screenshot seems to be "full" brightness and the other is half - the checkerboard pattern, though, is the exact same. Same issue here with old caps that will be resolved with re-capping? Having trouble with screenshots - will try again later

    SE/30 Xceed greyscale adapter cloning thread

    That's what I was thinking/hoping. As I try to get across below, the only thing about the EXCEED card that really requires cloning is its ability to sync with the A/B and substitution of its output to drive its proprietary neck board. The rest of it is A/B switching its output from internal grayscale resolution to its function as a mediocre VidCard driving an external display. Much of the legwork has been done in dlv's project. In a quick review of the topic I found Balrog's post: "https://archive.org/details/MicronXCeedTechDocs — you may have to click "Show All" under Download Options." @Gorgonopsand I had a bit of a back and forth going about just about everything I barely understand and I'm grateful for his lessons. I dragged in a tangential discussion about developing for 030 PDS as a simpler approach than going straight to NuBus, which puts discussion there right smack into this thread. The most useful thing I brought up was probably using the Macintosh II Video Card (aka Toby) as a design example and pointing out the in depth documentation of it in the Designing Cards and Drivers for the Macintosh series. I'm going to posit here: A - the external only XCEED card is an 030 PDS implementation of the NuBus Toby card as its output is the same as the 640x480@8-bit Grayscale Card; LEM B - the Internal GS XCEED card implements the ability of the Macintosh II High Resolution Video Card to output the 512 x 384 resolutions for driving the later Apple Displays that are missing from the TobyCard. But the XCEED version was tweaked to match the 342 vertical line resolution of Compact Mac video. LEM Thankfully, that card's default setting is 512 x384***** which makes sense as coming up in 640x480 would be useless in the case of a system configured with the smaller display. Im thinking the same must be true for the XCEED card defaulting to internal, no? So tweaking the Internal GS driver shouldn't be necessary for doing an internal only clone? Schematic, driver and DECLROM info for Toby are in Apple's Developer Docs, but I've yet to find PAL formula listings for the Toby card. I believe they're out there on the web, if not somewhere in Apple's Developer series that I've yet to run across. I can't imagine that dumbing a Toby card down to run the SE/30 512x342 internal display would be an insurmountable problem? As Toby constitutes the XCEED card's external monitor support function, adding external support of the same spec, if not identical in implementation to that of the XCEED's would be easily enough done in phase 2? **** Macintosh II High-Resolution Video Card: New Features

    If you know someone who paints warhammer (or other table top game) models they'd probably be able to retouch it for you. It's just screenprinted on stamped aluminum.

    SE/30 Xceed greyscale adapter cloning thread

    Right, OK. I should've been more specific in that I meant *functional* clone; in other words, not one that necessarily uses the exact same components (that would be unrealistic!), but one which mimics the original's functionality using modern components. This, then, would allow all the functionality to be reproduced, and then, via a firmware update or something, more advanced features can be added (like the Floppy Emu, where BMoW added HD20 functionality simply by updating the firmware (though some very early models needed a hardware fix or two for it to work due to thier being a slightly different design, as I recall)). c
  25. You’ll want these drivers most likely. I know they work because I uploaded them. I think your Radius SE will run fine without the drivers, but you may not get the performance boost. https://macintoshgarden.org/apps/radiusware-1990-displays-41-accelerator-29-radiusmath-15

    AppleTalk net cable

    Not sure on the date, but I ran across the following yesterday. http://www.tmetz.net/os/Apple/Inside_AppleTalk.pdf That might be useful. Appendix A: LocalTalk Hardware Specifications begins on page 520 of the PDF. So, I take it that for a proper network you need the little adapter boxes one way or the other? The advantage of PhoneNET being that you don't need the special 3pin miniDIN cables?
