      Just think, having a Quadra 950 in 1992 would be like having a Mac Pro today… except with more slots, more expandability, and on-board SCSI!

    • Alright, round 2!    Bit of an update: After much time and sparks, the Q610 is recapped. After following the idea of cleaning the cap areas and setting the termination jumpers correctly (HDD=0, CD = 3), i'm still stuck. No drives show and scsiprobe show the bus still as not terminated.  Can anyone guide me as to what I should do? If pictures are needed, I'll send some  
    • Did you ever get this resolved? My LCIII started having the same problem intermittently, and it's now escalated to a permanent condition!
    • You're forgetting the proprietary Silicon on the board, very Apple that.   We've already got a cleaned up version of Apple's schematic ready for mucking about a bit from a ground up build. Has it been checked against the Bomarc schematic? I need to get at least the memory page of that version.   Don't get me wrong, I love the process of 1:1 repro work from an existing PCB and mucking about with it. That's really the only PCB "design" I've done, right down to sanding off the layers of a complex later 90's PCB, albeit the very small, PCMCIA/I/R daughtercard for the 1400 030 Bus.   I want to see what @techknight and the FPGA/CPLD boffins can come up with in terms of simplification/parts count reduction and hopefully a bit of modularization of Lthe ogic Board's block diagram. Two approaches, one from the top and one from the ground up happening concurrently should be beneficial to both projects I'd think.    Thinking PicoPSU/Plugged in only at first. After that a 24v battery pack that would match the three hour battery life of the MacColby SE30 might be possible?   Enough of this tangent! I'll do some doodling in AI and start a new hacks thread about my SE/30 Portable notions if anyone's interested?
    • Ha! The idea of a completely non-Apple SE/30 is great. Let's keep our SE/30s running indefinitely...   As part of the Classic II gang gang, though, I'm obliged to cast my vote for the Classic II... although it's got custom ASICs out the wazoo, so it'll be harder to do. Oh well, SE/30 it is.
    • "need" is a strong word here I'd suspect it would be a lot easier to muck around with the board after the event if you know you're starting from a working layout and schematic.
