OK, I'll have to look into the chip select lines and better understand that so I know exactly what I'm taking out. For what it's worth, I didn't use hot air for installing the chips. My usual solder, chip quik flux and drag soldering, with some spot checks as needed. I don't have low temp...

Hi folks, To avoid burying the lede, this is yet another SE/30 simasimac repair post. I've got one board that is just not cooperating with me, though at least I've narrowed down some areas I think are most suspect. Current condition is a boot to jailbars, no sounds. RAM and ROM are known...

Took a while since I didn’t have any orders to submit but I finally got around to buying some caps and filled out all spots marked for decoupling caps. Only three pads but they’re all filled in. I bought a size too small so they were tricky to get in but it’s done. R2 was removed (measured 33...

Oh, I suppose I should have mentioned that in the first post in terms of things I had tried. That was one of the settings I was toggling in a desperate effort to figure out why it wasn’t working. With regards to defaults, at least in my case it is default off. If I have TCP/IP disabled and...

Interesting. I’ll see about giving that a try. Any guesses as to why this is the case?

Since I just went through this whole process with my 3400c I figured I'd provide some input. LaPorta dropped a comment in my thread about looking in to an SD to IDE adapter instead of the CF to IDE I was using. I went out of my way to ensure the CF card had UDMA, I read online that was needed...

With the SD card adapter installed, everything's running smoothly! The WaveLAN driver and software did not play well with the CF card installation I had. Caused the whole system to be unbootable. I imaged the SD card to 8.6, plugged it in, and it booted up perfectly. WaveLAN installed, and I was...

One more last update. The BlueSCSI was sent off to the seller, who determined the SCSI connector had been soldered on upside down. While still pin compatible, it seems to have lead to it forming a weak connection with the internal ribbon cable. For the record, I purchased it assembled! So this...

I’ve got other orders to make, I’m recapping a 20SC and a Vulcan. I just was doing the online equivalent of muttering to myself about things I ought to do. One interesting observation I’ve made. From beeping out the pins on the existing chips I made a guide for what was common and what was...

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...
