  • Looking for slim and quiet love (7011 PPC)

    From Louis Ohland@21:1/5 to All on Thu Oct 27 09:01:31 2022
    Folks, I'm interested in some Super High Intensity Tinkering with a
    7011-25x system. Any pointers to such a system? No, the Australian
    system on fleabuy is a bit rich for me...

    I have one, it's a slightly more capable machine than it's more common brother, the 7011-220. Are you looking to borrow or own the 7011-250? I haven't fired it up for a few years now, I'll need to verify that it still works. I did look up the
    Australian listing, nearly wet myself laughing.

    I did hook up my 7011-250 to power (didn't bother hauling a 13W3 monitor down from the over garage storage yet), it started (and I *think* the hard drive spun up, not sure), but it went "crazy 8s" early in the memory test cycle, so this puppy would need
    some love to put it back into an operational state.

    Did you hit the yellow button for the full code?

    I didn't need to, but just for you: 103 202 216 (Unexpected interrupt during IPL tests). The IBM documentation points a finger at the system board (or Microchannel adapter), but I suspect that I'll just need to re-seat the memory sticks once, twice or
    thrice and it will move on. All of the 7011 models were famous for being memory-fussy. I'm not in a rush and I need to find where I hid the key for this system (unlike the C20s, where only a coin was needed to move the "lock" around, this 7011-250
    needs a real key for the lock).

    Not what I expected... the GXT150 adapter has failed, once I removed it the boot process got to the point where it is trying to boot from the hard drive (code 299) and you can hear the drive recalibrate repeatedly, so it also died. Only one bank of 4
    16MB SIMMs are populated, so right now it's only got 64MB of RAM.

    So while it might be possible to load another 50-pin SCSI drive with AIX 3.2.5 from CD and run from a serial console, I'm inclined to just scrap it. I can probably sell the power supply, the 2.88MB floppy and possibly the memory SIMMs.

    1.2.8 D/T7011 MOD250 PLANAR SPEEDS

    Record number:

    Device: D/T7011
    Model: M
    Tip key: 015
    Date created: O94/08/29
    Date last altered: A94/08/29

    The 7011 model 250 now comes in a 80Mhz version. The
    orginal mod250 was 66MHz. It's model numbers include 250, 25T,
    25W, 25S, and 25E(field upgrade). Beginning in August, 1994,
    the 7011 model250, 25T, 25W, or 25S can be ordered with
    feature code 8000 which is an 80MHz planar. Any 7011 can be
    graded to a 7011 model 25F(80MHz). The 80MHz machines
    come with a sticker on the inside of the operator panel door
    that reads "80MHz". The rear label of the 80MHz machine also
    states it is an 80MHz machine.
    Both planars look identical. You must verify the FRU
    number you are installing is the same as the one you have
    pulled from the machine, and verify the information on the
    rear label of the machine before replacing all planars on the
    7011 model 25X. The FRU numbers are found by looking on the
    underneath side of the planar once it is removed from the
    machine.
    FRU numbers for both planars are:

    51G8101 - System planar (66Mhz)
    8184306 - System planar (80MHz)

    In addition, the 80Mhz model 250 requires a faster
    GXT100 or GXT150 local bus attached graphics card. The
    FRU numbers for the GXT100 (pn51G8070) and GXT150 (pn51G8092)
    have been subbed to the faster card. Either FRU will function
    in a 66MHz 25X, however, only the new cards will function in
    the 80MHz machines. All model upgrades will include the faster
    graphics card. All new build 7011 mod 250's are being shipped
    with the faster graphics card installed.
    FRU numbers for the GXT100 and GXT150 graphics card are:

    GXT100 - pn52G3206(new) subs from pn51G8070
    GXT150 - pn52G3207(new) subs from pn51G8092

    SYMPTOM: A DEFECT HAS BEEN FOUND WITH A CERTAIN LEVEL OF THE
    7011 250 PLANAR. THIS DOES NOT AFFECT THE 7011 250 TURBO (80MHz)
    OR EARLIER LEVELS OF THIS PLANAR.

    THIS PLANAR IS COMMONLY REFERED TO AS A PASS 10 PLANAR. IT
    CAN BE IDENTIFIED BY LOOKING IN THE VITAL PRODUCT DATA (VPD) FOR
    ASSEMBLY P/N52G3286 EC LEVEL D18367 OR BY DOING A VISUAL
    INSPECTION OF THE BAR CODE LABEL UNDER THE MICROCHANNEL ADAPTERS
    AND LOOKING FOR P/N52G3286.

    THE DEFECT WILL ONLY OCCUR IN CONFIGURATIONS WITH ALL 8 SLOTS
    POPULATED WITH MEMORY SIMMS (2 QUADS OF 4 SIMMS EACH). FURTHER,
    THE PROBLEM ONLY OCCURS WHEN THERE IS A SPECIFIC MIXTURE OF
    SIMMS BETWEEN THE TWO QUADS. ONE QUAD MUST HAVE SIMMS WITH
    16MB OR 32MB EACH AND THE OTHER QUAD MUST HAVE SIMMS WITH A
    CAPACITY OF 2MB, 4MB, OR 8MB EACH.
    THE SYMPTOMS THAT MAY BE SEEN WILL DEPEND ON WHAT MEMORY
    CONFIGURATION THE CUSTOMER HAS. YOU MAY SEE ONE OF SEVERAL
    LED SYMPTOMS WHEN RUNNING IPLROS TESTING AT BOOT UP.

    FLASHING LED888/102 206 (MEMORY ECC ERROR)
    FLASHING LED888/103 202/220 (UNIDENTIFIED MEMORY ERROR)
    FLASHING LED888/103 202/219 (ROM -> RAM REMAP)
    SOLID LED 186 (OCCURS AFTER IPLROS AND IT TAKES A WHILE)

    MOST OF THESE LEDS POINT TOWARDS A MEMORY TYPE ERROR.
    DO NOT REPLACE MEMORY. THE MEMORY IS NOT THE PROBLEM.

    PROBLEM ISOLATION AIDS:
    FIX: THE ONLY FIX AVAILABLE IS TO REPLACE THE PLANAR. IF THIS
    CONFIGURATION IS FOUND IN THE FIELD, CONTACT THE CHICAGO SUPPORT
    CENTER. ENGINEERING L3 WILL REPLACE THE PLANAR AT NO COST TO THE
    FIELD. IF THE CUSTOMER CAN NOT WAIT FOR THE PLANAR, THEN REMOVE
    THE SMALLER QUAD OF MEMORY UNTIL THE PLANAR IS OBTAINED.

    This applies to service mode.

    A problem has been identified with D/T7011 model 250 with the
    GTX150 adapter installed and IPLed in service mode. Error code
    LED888/103 803/942 or SRN803/942 may be displayed on the 7011
    if the GTX150 adapter switch are set to 1.ON 2.ON 3.OFF 4.ON for
    a refresh rate of 77 Hz. The work around for this failure is
    to change the switch setting to switch 1.OFF 2.ON 3.ON 4.OFF
    for a refresh rate of 74 Hz on the GTX 150 adapter. The failure
    is only seen IPLing the system in service mode from the hard
    drive. For further information please contact RISC/6000
    Support in Chicago.

    So I parted out the 7011-250 and started selling the parts on eBay, then I turned my attention to my 7011-220, which booted up to code 55x (usually 554) -- yet another bad hard drive! So I went looking for an external SCSI CD-ROM so that I could run the
    standalone diagnostics and do the test/format/certify routine on my dwindling stash of narrow SCSI drives to find a suitable replacement. Over the garage I found a nice 3509-705 and nearby I rediscovered an old box of salvaged parts, which included a
    66MHz 7011-250 system board! I had already sold the GXT150 and local bus riser on eBay, so I won't be able to test those parts, but after I get the 7011-220 running properly I'll revisit the 7011-250 and see if I can get that running as well.
