For anyone wondering I haven't really had the time to work on the board. Work is eating up a lot of my free time but I'll make an effort this week to try and get it done. :)

Yeah. Otherwise I have the feeling this will produce a few units then end up as dead as the protocahce :(

The BSD docs have some info. Check the mac68k netbsd source/dev history. I know a few people over the years have gotten access to apple ASICS and the like to be able to get wierd things like DSP cores working. Maybe someone knows someone. :)

Yeah you're right, they're swapped. From the looks of it I reordered the output pins at some point and that changed the order of the input pins also.... (e.g. the wire change updated the whole net vs just the one wire). :O :O

Why not just emulate/clone a scsi Ethernet adapter?

You try just giving it a nice hard wack on the analog side of the case? I have a fully recapped se/30 and if I don't use it for a few weeks it gets grumpy and dosen't post to the happy mac. Hitting it fixes it. :^)

Yep the X is the dot/ground pin. Just a standard SIP resistor array. eg: https://www.mouser.com/ProductDetail/Bourns/4610X-101-221LF?qs=sGAEpiMZZMvrmc6UYKmaNVaHnB8Kz7%2bapsej3SXibYs%3d https://www.mouser.com/ProductDetail/Bourns/4610X-101-331LF?qs=sGAEpiMZZMvrmc6UYKmaNUXZLNzTfjvk1PNWiKwz6FM%3d

Nah the packages here are pretty big. Tack down each corner and drag solder them and its really easy. Shouldn't even need a hot air gun really. I'm not going to expect the at home user to be able to hand solder 0805 resistors ;) Generally I like to try and keep costs down when I do a board...

Yes that's fine. Give it a shot. :)

Hello! Din would be the outer version yes. The "right" version has a right angle 50 pin scsi for internal use. That's why it has the power connector so you don't have to run a usb cable inside your case if you don't want to, say for a standalone setup. The db25 pinout should be the same, but I...

Well there's always the thread extension :P. Real background tasks on the mac seems to be an art few developers mastered.

The prorouter in eagle is nice enough to get the job done. I use it for isolated runs of a few traces when I've handfit most of a board to speed up work.

Speaking of ugly.. BEHOLD THE VERSION FOR THRU HOLE PURISTS MINIMALLY AUTOROUTED ;) ;) ADHERES TO SOME SIGNAL INTEGRITY STANDARDS UPLOADED TO GITHUB MY CAPS LOCK IS STUCK :(

I never really had an issue with PLCC sockets, you just cut out the center and solder it like this: The main issue with through hole PLCC is that the pin arrangement is horrible for multiple in line chips. It's possible but very very ugly.

:) My house is surrounded by snow and fallen trees so I had some free time to throw this together. I like the idea of having a custom rom in my se/30 because a 10 minute ram check is tedious every time I boot. However seeing that there are no open source projects out there for a rom-simm, and...

What version? I have a v4 and v5 and haven't had that issue. V6 looked too complicated for its own good.

Well the crackling is a bad ground. Shouldn't be too hard to solve. Solder joints do break over time when exposed to high amounts of vibration, perhaps even the minute movements in a crt due to its high khz feedback were enough to move it lose over time. A generous reflow of all joints with a...

The way we used to do it with old game boys (DMG's) was to use a razor blade to separate the digitizer/polarizer with a razor blade and peel it off, then clean the residue with 99% rubbing alcohol and align a new polarizer. Considering that the polarizer already looks like its done all you need...

Serial terminal (zterm) to a computer that has a lynx setup. Best you're going to get. Even a mac plus can do serial. Otherwise you can always follow this link: http://www.keacher.com/1216/how-i-introduced-a-27-year-old-computer-to-the-web/

Might be ram isnt seated correctly or the ROM's are shot.
