OK, well the hot air station will be useful then anyway since I will likely need to remove those chips for testing. I used a magnifying glass to investigate the pins closely. No shorts that I could see. I could also beep that out to validate, I don't think any pins would be internally shorted...

OK, sounds good! Thanks all for the tips. I did find some suspect solder joints and touched those up already. However, the majority of the issues I'm having stem from not having a hot air station. I plan to snag a cheeky lil 858D today or tomorrow to resolve that. Doing it with an iron is...

Seems so. I went with them because I switched jobs and had to hand back an entire stack of enterprise grade gear that I had built my network on but was only on loan as an employee. Since I already use Ubiquiti for their wireless it seemed the most reasonable quick replacement. It’s overall...

So, as it turns out it was my switch. Hooked up to the WRT54G and it works consistently. There’s now other issues, which cropped up after installing the WaveLAN drivers, but that’s probably down to the CF card being problematic. So, if anyone has issues with Ethernet instability on their 10M...

Here’s some quick photos of the card. I was not aware this card is a bit non standard so I don’t have any photos of it prior to modification. Whoops. My dubious soldering work is on full display here. The chips are a bit off kilter. I’ll be probing them out this weekend to see if any...

Partially managed. One of those dinky Unifi 5 port switches, I got it since a PoE powered switch was a more elegant solution than an AC powered one. It's not going to have much in the way of proper diagnostics. That WRT54G is also going to serve as an older device to see if there's some odd...

I'm taking any and all advice since this issue is driving me nuts! So much so that I'm snagging a WRT54G so I can use my WaveLAN card instead. But it's tricky getting that going, because I gotta get the drivers from... the internet. Oy vey. I'll admit I had no idea that IDE to SD adapters...

That was one of my guesses, but I have not been able to find photos of a card that looks similar. There's little identification on it; only a brand and a date. Kelly Micro, 1994. It's also not the same shape as the ones I can see online so I may have to simply do a bunch of experimentation to...

That's the idea, but I'll need to have an idea of what to expect! The card is packed quite densely so I can't just test from leg to pad, such as it is. That's why I was wondering which pins on the chips would be common so I could at least beep those out for validation. As for the other ones...

Sneaky little update. The datasheet for the FL and FTL variants of the chips I've got here are identical. The pinout section is marked as relevant for both of those. So, it's down to the chips or the soldering. I'll contact the seller to ask if they run tests on chips before they send them out...

Thanks! I did not think to double check the pinouts but I really should have. It's the same IC part number aside from a differentiator (missing a "T") to indicate it's just SOP. Nevertheless I'll go dig up the sheets and compare. As for checking the soldering job, how best would I go on about...

I'll have to do that, despite the tediousness that will entail. Oh well! I'll get on that test and report back.

In the continuing saga of the 180c I'm working on, I dove right in to tackling a memory expansion modification to get it up to that sweet 14MB limit. The card is a 4MB expansion card but has all the pads for 10MB. I wasn't able to source exact replacement chips, instead I found them in a...

I'm quite certain it did not have issues prior to the swap. This is why I figured it was driver issues, I have not been able to get it back to 8.6 for a number of reasons, and I assumed there was maybe an update in there for the underlying drivers. Perhaps not. The reason I'm pretty certain I...

My lovely Powerbook 3400c has been behaving a bit strangely since I swapped out the hard drive for a CF to IDE adapter. I still have the original hard drive so can swap it in as needed for additional testing, but it's on its last legs. I've installed 8.1 via emulator, and then dd'ed it to the...

Thanks for the heads up, but that was the first thing I did!

Updating this thread as imactheknife and I worked a bit in PMs. Hopefully this information will be of use to someone. The inability to boot from floppy mentioned before was a silly mistake, due to an incompatible boot floppy. One built from an appropriate set of images off Macintosh Repository...

I’d like to try the interconnect board. I have already tried the reset procedure. Thanks! I will give the boards a cleaning tomorrow.

Well, no dice. Same behavior with the replacement daughter card. Either they’re both bad in the same manner or it’s something else entirely. Damn frustrating. I really wanted this to work!

I made that username a while ago when I was living in Canada. Now I’m in the states (NY). I’ll go snag the daughter card I saw on eBay for a relatively good price. Thanks for the advice! I hope this fixes it up. I really like this PB, it’s gonna be a permanent member of my collection.
