Does CTRL-[ work? I have used this on keyboard without Esc in the past (not on a Mac though...)

I'm wondering why open source matters here; you won't get very far without buying the proprietary silicon from one of the big vendors, so what does it matter if you use the tools provided by them also?

HI Michael - I have 3 cards including one that matches your picture exactly. Happy to mail them up from Melbourne if you want to try out one that is supposed to work. I don't have a NuBus Mac right now...

I'm looking at Inside Macintosh vol VI. "When a multiscreen system starts up, one of the screens is determined to be the startup screen, the screen on which the "happy Macintosh" appears." Is the Micron Xceed the "startup screen" when no external monitor is connected? Does anyone know or can...

Actually I am working on a thing to do this. I have the video from my SE/30 brought out to a header on the rear slot and have made sense of the output with the oscilloscope. I am working on various display schemes (VGA first) using a MAX10 FPGA. The MAX10 is not expensive but is a little bit...

If you really want to use solder paste - like for example you have a reflow oven - any PCB house will make a solder paste stencil for you and it doesn't cost more than a PCB, often it is part of the package. An art store silk screen and rubber squeegee is the only other thing you need. I used...

Oh no! That's an ugly, ugly way to use solder paste. It is normally applied by using a squeegee over a stencil that applies a controlled amount to each pad rather than blobbed out of the syringe bridging all the pads. I can't believe this guy has so much gear (EEVBlog DMM? Hot air?) and so...

They distort somewhat when coming off, and go back on the same way. As JDW says in the video putting them back on involves pressing them down until the pin comes through the hole suddenly and stabs you!

Chances are something is not running smoothly. There is very little effort required to transition the mechanism between inserted and ejected if everything is clean and lubricated well. Did you get the four press-fit washers off and remove the floppy tray completely? When old grease dries out...

Would this be from Fusion 360 perhaps? I absolutely hate that the default is not “join” rather than “new body” when possible...

The one you linked is the one I printed. When I say "not the same" I mean it works fine, just doesn't look right. Even in highest detail in Prusa PLA Vanilla White you still see obvious layers. I have some hope with my new roll of ASA filament (much tougher apparently and acetone-smoothable) but...

I wish I could find one of these units. I have 3d-printed a couple of different versions but it's not the same.

Wow, locals - Hi, I am in Melbourne too. I do not have a lot of experience with custom ROM but I have just received a BMOW for the SE/30. It did not work unless two layers of kapton tape were added on the back of the SIMM. the thickness of the PCB is the issue so the tape needs to go over the...

Depends on how you build it but you could maybe build the 64-pin ROM with a JTAG header on it, have some cheap micro for the purpose?

Double-ended ROM @chopsticks? I'd probably be interested.

Best way to find out would be to catalog exactly what chips are damaged, and see if you can replace them. Of course you would need to remove those chips so you may as well, and after that you can assess how bad the PCB is, whether pads remain attached to the board, whether holes and vias clean...

And it arrived today! Only to show a simasimac-like screen and no startup tone! I applied two layers of kapton tape to the reverse of the ROM. A strip over the contact area and vertical strips on the outside of the holes, where the clamps hold the SIMM in to the clip. The BMOW PCB is noticeably...

d'oh! I forgot about the replacement ROM thing. There's a BMOW ROM in the post that has been in transit for about three months, that should fix it.

I just received 8 x 16M SIMMS and installed them in the SE/30. This image shows the system report: Is it the case that 7.5.3 only supports a small amount of RAM and will mark all the rest as used?

Nice job! Linear patterns for the repeating lines too? Did you have to buy a license though? I thought that for general maker use it was free until you make $100k in income with it?
