Glen's driver fails to match my card. Doing some archeology, in the Linux kernel, I see: /* Known <Cat,Type,SW,HW> tuples: (according to TattleTech and Slots) ... * Sonic Systems Ethernet A-Series Card: <4,1,268,256> ... * Farallon ethernet card: <4,1,268,256> (identical to Sonic Systems...

268/256 by the look: I could try patching Glenn's driver to match this and see what happens.

I've confirmed that my PROM read is identical to the slotrom dump. @eharmon I've also used your ROM Fiend extensions to HexFiend to see that many of slotrom's debugging messages make sense.

@cheesestraws I'm now sure that this card is from the "Sonic Ethernet Series". Trawling MacWorld's from 92/93, I see a number of models for various Macs .. but no PDS versions for IIsi or SE/30 specifically. Does your card work on an SE/30, and if so using what driver? @halkyardo Thanks for...

I do have an SE/30 with a good Asante card installed. I'm reluctant to disturb it, though, since I'm not sure what can be learned that's not already known. Yup. TattleTach and friends all see the card and confirm it to be a Sonic. And 16Kb of device RAM is seen. Yet no installer I've yet found...

I've tried the driver from the Asante 5.1 release with System 7.1 but the card isn't seen. And standard Apple code should recognize MacCon anyway .. the MacCon in my SE/30 is.

I wasn't sure about reading the ROM directly from the host, so I pulled the chip. It turned out to be a DM74LS417N which is a 256byte TTL device that's far too ancient for my TL866ii+ to understand! So some fakery was required to approximate it to a familiar 1kb 2716: But I got a dump: So, as...

Tried another machine and got a good copy. Don't the love floppies:cautious: No driver match for the card found though.

That's an excellent site. I tried Sonic Systems EtherLAN 6.1 Drivers but no joy. And Sonic Systems EtherLAN 7.8 Drivers is sadly unusable: incomplete or corrupt.

Thanks. I haven't tried the Asante driver. I'll give it a (them) a go.

I've just successfully restored an IIsi (detailed discussion posted on TinkerDifferent) but the machine has an unidentified PDS ethernet adapter. The card isn't recognized by Apple network code or by NetBSD. Its vendor code is 0x0410 which might be Sonics Systems, Inc .. but I've found no driver...

I left the machine soaking and I soon noted how hot the PSU runs. There's no built-in fan like its IIcx/ci/etc cousins. That must contribute to the IIsi's poor survival rate and lead to these bad goo explosions.

I got the daughter board out again and took off the regulator chip: Gag. Loads of goo and solder mask eaten through to a ground trace. That was pulling pin 7 down to about 0.2v and resulting in the regulation always being enabled. Pin7 is pulled up to +5v by a 100k resistor so the electrolyte...

Yikes, I'm surprised goo had got to the back end of your machine. Mine had goo fromt the low-voltage side oozing out towards of the front end. Luckily, it hadn't reached the logic board. I gave the main PSU board a good IPA bath but sadly that didn't help (though it looks much better now). I...

Thanks. With a relay and transformers to worry about, I too am thinking about a very shallow, barely-covered bath.

I too have hit this soft power issue. I picked up a IIsi for which the logic board was mostly fine although needing a recap. The PSU was a disaster, however: trickle supply was OK but nothing else. Cap goo was everywhere. The main HV caps were fine but I replaced the rest. Here's one example of...

Get top-3.3 from https://www.aux-penelope.com/jagubox/ .. it's fine.

Another datapoint here: I have a IIci with ROMinator II (which is based on the IIsi ROM) that won't launch A/UX 3.1, but it's perfectlyhappy with the stock ROM. I've never bothered to debug this, but I suspect it may be related to the RAM configuration.

So, my Pismo battery was a third party replacement I'd got back in 2003! It now managed to hold charge for perhaps only 10 minutes .. so I needed to do something. On eBay, I picked up some dead batteries for a few backs each so that I could play around taking cracked opne. I got 2 Apple branded...
