Re: 8GB boot restriction... Hhmm ..4? Beige G3s have OFW versions 2.0f1 or 2.4 and are not updatable (unlike the B&W G3). The 8GB boot restriction applies to both. Yes. See https://lowendmac.com/1997/beige-power-mac-g3-1997/ and https://lowendmac.com/1998/beige-power-mac-g3-1998/ .. and I can...

Be aware that the Beige G3 can boot only from partitions in the first 8GB of the IDE drive due firmware limitations. I've had good luck with 64GB 40-pin IDE flash modules in my G3s.

MacTest Pro will tell you whether the cache card is present and working. Also see the IIci Developer Notes for the memory addresses of the cache data and tag RAM that may be pokeable from MacsBug (I haven't tried).

Seconded. Leakage eats resistors. For more details:

Weak or totally absent decoupling caps like C20/C22, may not stop the machine running. In fact, a logic board could work with no decoupling caps at all, albeit unreliably! If those tiny ceramics have been elsewhere, in particular C10/C11, then that would explain no audio.

I see lots of hits for "LongDateTime" on archive.org. Have you trawled there?

From the man:

Interesting. I occasionally use a Braun toothbrush to scrub boards. And I've heard that using toothpaste can add abrasion. I'm also a strong advocate of dental probe tools to assist awkward desoldering. Perhaps I could finally like dentistry.

And a big shout-out to DAT tapes ... A few years back, my trusty SE's original harddrive flaked-out and the only backup I had was on old Retrospect DAT tapes. Of course, I'd lost any floppies containing the right version of Retrospect itself. Nevertheless, I downloaded a copy from...

in my case, yes, the fix was this easy to adjust a timer. But it looks like you have a later revision of this series of NICs which will require a different solution .. if, indeed, this is the problem.

Likely a known issue.. Check out this thread: https://tinkerdifferent.com/threads/asante-mc3nb-rev-g-nubus-nic-getting-10base-t-working.2040/#post-18843 And Glenn Anderson's webpage: https://www.mactcp.org.nz/ethernet.html

Tried to fix it but quotes remain mucked up. The web editor isn't helpful :confused: >hwint3 is 211C0 but the A2 was 17135E0. Right.

That indeed checks out. That R5 value gets to the expected spot! The PPC step I needed was 100000000 and more! Thanks. I'll try that next time. Yup. I don't know. I'll see if I can determine. Branch dot. A trivial spin. Machine code 48 00 00 00. Yes. DingusPPC floppy doesn't work...

It's been a while since I last repoted but I've made some progress. I've changed the thread title to reflect what I've been up to: So I first tried to get an instruction trace for booting into DBOF. I captured stdout to a file but the spew was so vast that my M4 MBA ground to a standstill -...

Yes, finger trouble. [I do also have a pm7600.] I see now that the code in machinepdm.cpp only has pm6100 properties defineed Yes. A FAT floppy is readable on my pm7100 under DBOF.
