| Photo Request : 5500, 6500 and TAM Logic Board | |
| Posted by: joevt on 2025-12-05 00:32:45 For 6500 and some other Macs, mac-io needs to be replaced with the actual device path for the OHare chip.For the 5500/6500/TAM it should be pci1/ohareI updated the script in the probe-ids.txt.zip attachment. | |
| Posted by: joevt on 2025-12-05 01:37:26 Ok, this one should work. I switched to using find-package because dev and find-device do extra stuff like output a beep on failure or change the active-package which we don't need to do.But find-package doesn't know about device aliases on B&W G3 so I have to get the mac-io alias manually from the /aliases node.find-package on 5500/6500/TAM is ok with paths that use a device alias (such as pci1/ohare). | |

Anyone have a 6500 that uses $303C or returns cpu_id values that differs from those of @MacJunky ?

Maybe. For the cpu_id part of the ID, we see that the probing algorithm sets the output of each of 3 pins to 0 in turn and the result is that pin should be read back as 0, at least in the case of a real Power Mac 6500. i.e. Without setting any of the 3 pins to 0, we get 110. Setting bit 2 to 0 should return 010. Setting bit 1 to 0 should return 100. Setting bit 0 to 0 should return 110 (no change since it's always 0). Why does DingusPPC return 111 for the cpu_id bits? It thinks that an `emmo` input is connected to bit 0 like on Power Mac G3. | |
Posted by: joevt on 2025-12-06 04:35:36Could this info have been extracted from the schematics? Maybe.Probably not. I don't see in the schematic how CPU_ID0 is set to 0 unless R165 is removed? Well, I don't think anyone's shown a photo of that location on a pm6500 yet. The photo at #12 is for a 5500. | |

Posted by: joevt on 2025-12-06 15:17:26Why does DingusPPC return 111 for the cpu_id bits? It thinks that an `emmo` input is connected to bit 0 like on Power Mac G3.According to the code in HWInit of gazelle ROM, the emmo pin is connected to CPU_ID2 instead of CPU_ID0. The emmo pin starts the Serial Test Manager which exists in many (all?) Power Mac ROMs. The string "Serial Test" exists starting from the first PCI Mac to the last 32-bit New World Mac ROM. Maybe it has a different name in the 64-bit New World ROMs. If it exists in earlier ROMs, it might not have a menu. You probably don't need this anymore, but if anyone is interested...R165 exists so CPU_ID should be pulled high so maybe CPU_ID0 is pulled low by whatever J18 "DirectConnect" (MLB system connector) is connected to? What is DirectConnect connected to? | |
| Posted by: MacJunky on 2025-12-06 19:47:24 R165 is tied to ground through the chassis harness and Monitor Out Board. Actually this may or may not be of note... I don't have a 6500's Monitor Out Board, the one I'm using is from a Performa 631CD. My chassis harness is PN: 590-9997 and was advertised as being from a 6400. I haven't had the case and harness that my 6500 logic board came in for quite some time.   | |
Posted by: joevt on 2025-12-07 00:14:16R165 is tied to ground through the chassis harness and Monitor Out Board. Actually this may or may not be of note... I don't have a 6500's Monitor Out Board, the one I'm using is from a Performa 631CD. My chassis harness is PN: 590-9997 and was advertised as being from a 6400. I haven't had the case and harness that my 6500 logic board came in for quite some time. I see that the cables from the motherboard that you show in #46 for the non-SCSI side of the top half of J18 (S1 to S50) has a 6 line cable for S1 to S6 and a 34 line cable for S7 to S40 and a 7 line cable from S? to S?+6 (where S?+6 ≤ S50 probably S44 to S50)? Anyway, BOXID0 is S18 which is line 12 of the 34 line cable which you have marked in the above picture. Do you think the 6500's Monitor Out Board is similar to that of the Performa 631CD? I can't find documentation or images for 590-9997. There is a note on the schematics on sheet 22 for BOXID0 which says something like "Grounds signals from 3.3V to 5V" though the first word is hard to read. BOXID1 and BOXID2 have capacitors to ground C434 and C435 but the capacitor to ground for BOXID0 C430 says "NO STUFF" which means it doesn't exist? | |
| Posted by: MacJunky on 2025-12-07 08:34:20 Unfortunately I can't find my own pictures of my 6500's old Monitor Out Board. Zone6400 used to host a picture for differentiating between the 6400's 922-2547 and 6500's 922-2996 boards. I've attached it for reference.  The 590-9997 harness I have now is as far as I can remember basically identical in appearance to what was in my 6500, though I don't think I had that one fully out of that particular case. The part number is printed on the IDE cable.    I don't think Page 22 of the schematic says C430 is "NO STUFF", I think that message is for C130, as it also specifies the same for C131 and C132. On my board I have C430 stuffed, and C130-C132, C440 not stuffed as per the schematic.  | |
| Posted by: pizzigri on 2025-12-08 04:46:47 At home I basically have every AV board made, I have to track it down and I can post pictures. | |
| Posted by: pizzigri on 2025-12-08 13:45:49 Argh, cannot fined the box where I buried those AV boards. A question not related, but what does VT-A and VT-B mean on page 16 of the schematic? It specifies whether one or another R or C is stuffed, I have both a 5500 and a 6500 and both are VT-B according to what R is stuffed. Last but not least, there seems to be a third rev of the 6500 board, that uses a slightly different layout (i.e at least one electrolithic cap is replaced by a tantalum) and also uses an updated video chip. | |
Posted by: pizzigri on 2025-12-08 14:08:41That's my 6500/225. It has 8MB RAM soldered onboard, and I currently have it overclocked to 300MHz. It also has a non-functional Rage Pro Turbo PCI chip soldered onto it and is utilizing a Radeon 7000 as main display graphics card.Stupid question I know, but the Pro you soldered had all the correct resistor switched to power it at 3.3V right? Since I also am going to attempt this I just wanted to be sure. | |
Posted by: joevt on 2025-12-08 14:25:22A question not related, but what does VT-A and VT-B mean on page 16 of the schematic? It specifies whether one or another R or C is stuffed, I have both a 5500 and a 6500 and both are VT-B according to what R is stuffed.ATI graphics chips have PCI vendor ID 0x1002 and a device ID that usually composes of two ASCII characters. 0x4750, // GP (Rage Pro) 0x4754, // GT (Rage II) 0x4756, // GW (Rage IIc) 0x4758, // GX 0x5654, // VT I guess VT-A and VT-B are two types of ATI graphics chips with device ID 0x5654? The letters don't always match the product name though: https://admin.pci-ids.ucw.cz/read/PC/1002 4654 FT Mach64 VT 5354 ST Mach 64 VT 5654 VT Mach64 VT [Video Xpression] 5655 VU 264VT3 [Mach64 VT3] 5656 VV Mach64 VT4 [Video Xpression+] A Rage 128 document at bitsavers explains that VT-A and VT-B are two versions of a chip with device ID for VT. https://bitsavers.computerhistory.org/components/ati/Rage_128/Rage_128_GC_Spec.pdf I don't know if the markings on the chips indicate which version it is: https://www.ardent-tool.com/video/ATI_Chip_Markings.html Besides components marked [A] or [B] in the 6500 schematic on sheet 16 are resistors marked [X] which have different values for GT-A2, VT-B, and GT-B but it doesn't say what to use for VT-A?If you have a serial cable, then maybe you can dump some info from your 5500 or 6500 or other OHare/Heathrow/Paddington machines: probe-ids: https://68kmla.org/bb/index.php?thr...00-6500-and-tam-logic-board.46450/post-576941 lspci for Open Firmware, dump-device-tree, etc.: https://tinkerdifferent.com/threads/apple-network-server-macos-based-roms-found.4756/post-42356 | |

Since I also am going to attempt this I just wanted to be sure.I went through and changed resistors and checked voltages before swapping the chip. The original still ran during this process. I also populated LC Filter [A] connected to PLLVDD using parts from the PCI card. Perhaps I should have done a larger dump earlier? 0 > unselect-dev ok

Posted by: joevt on 2025-12-09 05:48:03Perhaps I should have done a larger dump earlier?I didn't ask for the rest before. I just figure while one is in there, why not gather the other info from Open Firmware as well? The width of your output was truncated to 120 characters. What terminal app did you use to capture it? My lspci for Open Firmware requires width 550 or word wrap. Most of the useful bytes were captured. If I append enough zeros, then these are the parsed results: 00:0b.0 Host bridge [0600]: Apple Inc.

Others have reported having rev 01. I wonder how they differ? Is that Ethernet controller in a regular slot or the COM slot? I think the latter, since regular slots would have device numbers < 0x10. Is it a COM slot card that Apple made? You said your built-in ATI Rage Pro Turbo is non-functional. Normally, it would be at bus:device.function 00:12.0 like below (but I'm not sure that this example is the same ATI device as your Rage Pro Turbo):00:12.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc.

Posted by: LightBulbFun on 2025-12-09 15:30:13That's my 6500/225. It has 8MB RAM soldered onboard, and I currently have it overclocked to 300MHz. It also has a non-functional Rage Pro Turbo PCI chip soldered onto it and is utilizing a Radeon 7000 as main display graphics card. Have you checked if the Power Macintosh 6500 BootROM has a suitable fCode image for the ATI Rage Pro? without it, it will just appear like an unflashed PC PCI card in a mac its for similar reasons, that if you put a Wallstreet CPU card into a PDQ it will boot, but with no video, since the Wallstreet has no ROM for the PDQ's newer ATI video chip | |
Posted by: MacJunky on 2025-12-09 16:28:56The width of your output was truncated to 120 characters. What terminal app did you use to capture it? My lspci for Open Firmware requires width 550 or word wrap.Sorry about that, I forgot to enable wrapping. I was trying out minicom for this one and it has the option but I missed it. If you'd like a fresh proper dump just say the word. Yep, Apple branded COMM slot card. Have you checked if the Power Macintosh 6500 BootROM has a suitable fCode image for the ATI Rage Pro? without it, it will just appear like an unflashed PC PCI card in a macI don't think I'm capable of figuring that one out myself, I'm waiting for someone smarter to put their chip on in the other thread about upgrading ATi chip & VRAM. https://68kmla.org/bb/index.php?thr...-6500-and-possible-ati-rage-pro-upgrade.50635 | |
Posted by: joevt on 2025-12-09 18:48:35If you'd like a fresh proper dump just say the word.I would accept a fresh proper dump to see if anything interesting exists beyond byte 41. Standard PCI config registers are at least 64 bytes. All 256 is useful when a device uses config space for other registers or defines PCI capabilities. Have you checked if the Power Macintosh 6500 BootROM has a suitable fCode image for the ATI Rage Pro? without it, it will just appear like an unflashed PC PCI card in a macThe Gazelle ROM (Open Firmware 2.0.3) has fcode for ATI device ID 0x4754 The chip in @MacJunky 's pm6500 is not detected at all (vendor/device ID for the PCI bus number:device number is FFFF:FFFF) which is a different problem. If the chip is detected but doesn't have device ID 0x4754, then we can make a nvramrc patch to make the 0x4754 fcode image load for that chip. That would be useful only if the new chip is compatible with that fcode. If it isn't, then a different fcode image would need to be loaded from disk or a new ROM SIMM would need to be created and installed to override the built in ROM. | |
| Posted by: MacJunky on 2025-12-09 19:59:02 This is with line wrap enabled. There are some other differences in that I put back R133, and have drives connected for testing to see if adding a custom alias for the Radeon 7000 helps with the crashing while running RAVE accelerated games that the 6500 is known for.(and we have some other thread somewhere about) But I don't know what I am doing or what the real problem is, so don't mind me, I'm just screwing around. Open Firmware, 2.0.3
