The plan to redraw the available SE/30 schematics in Eagle has been in my head now for quite some time. It wasn't the task of having to redraw everything that kept me off, but I genuinely hate creating new devices in Eagle, so there goes that. Luckily @GeekDot kept bugging me about it and thankfully took over the job of creating Eagle devices for all the custom Apple ICs on the SE/30 board. This got me started and things quickly went down from there... a month ago I began copying the Apple schematics to Eagle. With most of the devices available this went through in a breeze. Only two days later I was already taking measurements on one of my SE /30 boards to arrange components and get them as close as possible to the original TxJW1xX.png Another week in (not doing much else than drawing blue and red lines all day long) and still somewhat surprised that things went through so quickly I was basically done with a first revision: 1.thumb.png.026106ea747eb07b0a3460ebf988904e.png 2.thumb.png.66a8a6ad87e6804a23b443bf86950d7b.png 3.thumb.png.13b072700d2fbab9b47f9d6ecdfd4258.png 4.thumb.png.730132abf6ae20148e805a4b837dcdc0.png Most components found their place in exactly the same spot as on the original board - unless it was useful to move them around a little bit. The RTC for example to make some space for a CR2032 battery holder. The battery is the only component I replaced with something that's not on the original. (yes I know, 72pin RAM, a single 16bit VRAM IC, accelerators, network cards, grayscale, and a PPC built right in - no) Goal for me was to set a baseline and verify the Apple schematics are even correct and would result in a running board before thinking about modernization efforts. One major advantage of re-doing the whole routing of the board is that everything can be made to fit into 4 layers, instead of the 6 layers the original board had. This is cutting costs dramatically. So on it goes with ordering boards... It took two weeks to turn this: render.thumb.jpg.b0ac8870041843112ee274901746dae3.jpg into that: IMG_6170.thumb.jpg.bdceca554225bdac85fd3af5f7b5ef43.jpg and a few hours later to find myself here: IMG_6180.thumb.jpeg.fad3c7baa7705c2cba6a08ad2ced16d9.jpeg IMG_6183.thumb.jpeg.9d27b1bc484d02c4e399472a29da1260.jpeg Only a few components missing to get her powered up for the first time - I went without any RAM to see if it actually does anything at all before bothering to solder in SIMM sockets. So a few more bits soldered down, a deep breath and the flip of a switch later: IMG_6184.thumb.jpeg.ad6338dfa8255be049509e9d5f0435c8.jpeg SUCCESS! It turns on at least and I got video. I seriously didn't expect it to even do that. No chimes of any sort though - would have expected the slow chimes of death because there's no RAM. At least the screen image is what is to be expected if there's no RAM installed which was a good thing. I took a break here, got some food for dinner, took a shower and while doing the latter it struck me... to get sound you need the headphone port to be present, because of the switch that's in there and connects the internal speaker to the amplifier. So back to the workbench... two little jumpers on the headphone ports solder pads and there we go - slow death chime was there indicating RAM failure. It was time to go to bed at that point but I couldn't have slept anyways. I got a donor board, moved over the RAM muxes, control signal buffer and missing address line resistor arrays, installed 4 SIMM sockets. I put in some RAM, hooked the board up again and couldn't believe my eyes when I was looking at that flashing question mark. :?: Well past bedtime a SCSI and floppy port went onto the board, back on the testbed with FloppyEmu and a hard drive connected... IMG_6190.thumb.jpeg.4891fa69d719af988fba626d033ca2d9.jpeg I sh*t you not the damn thing was booting from floppy - first board revision, rushed through copying the schematics, board layout, routing, putting it together... and it just boots. :evil: Not a single jumper wire (spoiler: yet!) Notice how there's no HD showing up? This is where rushing through things strikes back. :tongue: I copy-pasted the data lines to the SCSI IC from the nearby SCC - not noticing that they were sorted different in the original schematics. D24-31 on one and D31-24 on the other IC. End result: the data lines to the SCSI controller were reversed. Nothing that can't be fixed though. Popped the SCSI controller off again, cut the data lines and installed jumper wires. IMG_6192.thumb.jpeg.933ee8a50d95e5f93401b93e61cdeded.jpeg IMG_6200.thumb.jpeg.4282c0d7bcc40d0e3f5bd05fee1ca5e2.jpeg And that's how I ended up here: IMG_6194.jpg.6d972b16018ee6a876b95e5ffd5affcd.jpg The board now has a few hours of runtime on it and seems to be rock solid so far. Couldn't notice any differences from an original. Left to do: -test the serial ports (haven't done that yet because I totally never use serial ever) -test external Floppy and SCSI ports -chassis fitment -runtime runtime runtime The SCSI blooper has been corrected already for the upcoming rev 2 of the board. A few SMD pads will be added here and there for the fuses, SCSI Term power diode - those were through hole only for simplicity.

I love it, and I want one! To recreate the se30 logic board is amazing. But it also makes me wonder. What about creating an improved SE/30 logic board? Ethernet, wifi, SD-card, internal grayscale, external color, accelerator built in. How do you hardware creators feel about things like this? Is it not interesting because it's not original, or is it too much work to even consider? Too small market? * * Quote * Link to post [https://68kmla.org/f] Share on other sites * * * * * techknight techknight Posted Tuesday at 04:03 PM techknight * techknight * 68LC040 * [team_68040] * * 7886 posts * Location On Hiatus * + Report + Share Posted Tuesday at 04:03 PM Well if the EAGLE files become open-source, then I suppose the sky is the limit on modifying for modern amenities. Maybe including RaSCSI or BlueSCSI on-board built in somewhere. or changing the 30 pin SIMM sockets over to 72-pin. Replacing some custom logic with newer programmable logic, Possibilities are endless. But I suppose you have to start somewhere, and recreating the original design, consolidating it into a 4-layer board is impressive in of itself.

If we can figure out a few custom chips, then having an entire board using off the self modern parts and FPGA is easy. As you may know, we are working on an Xceed project and this could be implemented here. However, I am just THRILLED that we may have new original style logic boards for the SE/30s as so many have died.

Otherwise studying the memory map could untangle alot of the GLU since it does most of the address decoding for the system. Using the Motorola guide for the overlay or even borrowing that from the Plus/ SE might not be a bad idea their either. Anything additional I am missing? maybe it handles floppy selects as well, but I dont recall. * * Quote * Link to post [https://68kmla.org/f] Share on other sites * * * * * Kai Robinson Kai Robinson Posted Wednesday at 05:11 AM Kai Robinson * Kai Robinson * 6502 * * 393 posts * Location East Sussex, UK * + Report + Share Posted Wednesday at 05:11 AM Honestly just so blown away - this is the difference between a professional and merely an enthusiastic amateur like myself!
