the problem with many so called 'experts' who change money to fix vintage Macs or computers etc its that sadly many don't actually know the correct way to repair or fix things. over the years ive worked in electronics its shocked me more times then I care to admit in respect to the poor quality...

@joshc if you can get the exact size you need you can stretch tubing by heating it up (helpful if inner circle is too small. failing that In the past ive also used a 3D printer to print flexible filament like TPU, its worked well for me in the past fwiw

honestly I haven't taken much attention to if the CSII NIC's are 10 or 100, and it wouldn't bother me what speed they support if I could get one in Australia at a fair price, but so far ive had no luck these last 2 years to find one unless I want to speed silly money. where about are you from...

yeah its also common for people restoring vintage machines to use tantalum's in place of electrolytic so it pays to double check. I guess the good thing is they don't fail with a short these days (well less common anyways), they also don't leak! personally I prefer not to use tantalum caps. when...

@slipperygrey that sounds like quite the challenge then. if you do ever feel like going down that road and trying to reimplement AppleTalk in userspace it would be pretty awesome. id certainly be signing up to test and help out with that side of stuff. ive got a few Macs and they run everything...

I totally understand, hopefully the recap solves you screen issues. I have a real soft spot for the SE/30 myself

@slipperygrey just how hard would it be to move it into userspace? I guess doing that would allow it to be more portable and platform independent going forward?

@slipperygrey thanks for the info, wasn't aware that it used a kernel module. I guess that completely rules out any future macOS support. I have looked at netatalk v3 but as far as I know version 3 just won't and cannot work with system 6 or 7.x due to something being removed in the newer netatalk.

@slipperygrey how hard would this be to get building on modern macOS? I know Mac is bad based but uses launchd as its startup service. I use some somewhere called Homebrew unix software (its kinda like apt-get) that might be the way to go for this? Im not really skilled in porting software...

@David Cook great work there with the pcb, not sure if you have plans to release the files but even the physical pcb dimensions and the comm slot edge connector would certainly be handy to anyone working on projects for these slots. @Byrd yes as far as im aware the comm slot I was nubs or...

just for your own future reference, the black line/stripe etc on capacitors is always the negative terminal. unfortunately tantalum capacitors for whatever reason are marked the opposite to every other capacitor. a good tip/trick that I often use to help is to take a couple photos of the board...

As we all know Comm Slot II cards are worth rare and expensive to buy when they become available for sale. im wondering if it would be possible to make a modern reproduction board using NOS parts? Im not sure what model exactly but there is a Farallon Comm slot II card that used the Intel...

1A slow blow fuses, if you want to go fancy you could also replace with a 1a polyfuse. these work the same as traditional fuses but what happens is when there's a short etc instead of blowing the fuse and requiring a replacement to be soldered a poly fuse will just stop conducting and in effect...

@saybur it appears to still user the same cpu, however the DP83902(??) I believe is the network controller and it just looks like Foucs consolidated parts and moved to a more recent network controller, the MX98902QC used in the focus is probs similar/related to the DP83902A used in other devices...

interesting, its likely either power filtering or the more likely that the speed of the SPI bus running on that cable it putting to much EMI everywhere that's effecting the screen. being that the idc cable its going to act like an antenna you could try a quick simple hack just to see by covering...

I just had a look at that picture. what I said in my last post is still correct with regards to 9/12v AC. either will be fine to try. also here's the latest drivers for this SCSI ethernet adaptor its a zip'd disccopy image Im not sure what system version you plan to run this on 6/7 etc but ive...

no worries, see how you go trying 9v AC if that is unsuccessful try 12vAC, otherwise down the track if you can't get ahold of the required AC adaptor if you post a picture of the back of the pcb, myself or someone else can probably trace out the power traces from the power jack and figure out...

@aladds just had a look at you kicad files on GitHub, while I have no powerbook myself making the board shape unfamiliar to me. it looks good. I've got a design that I made to go inside a se/30, I used the same 50pin IDC connector for the SCSI and a smaller one like you did for the ethernet to...

obviously only going on the pictures, its most likely AC, it would make sense due to the full bridge rectified located at D3 (to the left of that large 2200uF cap). however while I could be be wrong id more expect it to be 9v AC input. you see 12v AC to DC conversion usually provides around 15v...

@saybur I wasn't expecting the dyna driver to work either, but I had the scuznet connected so I could copy some files onto the internal hd and I figured Id give the driver a go and to my surprise it worked. as for the w/r speeds fwiw the internal IDE drive (a compact flash card) peaks at around...
