YOWCH! :eek: Grease up all exposed surfaces of person with cocoa-butter before even painting with latex. 😬 Now that we have low voltage LED light fixtures, it might make sense to have a pull down light fixture counterbalancing your pot washing pull up faucet? Thinking dentist's/surgeon's light...

Wow, didn't realize folks were so actively pursuing this kind of thing? Thanks! I was thinking a castellated PCB was a higher/multi-level version of an interstitial adapter, but it refers to castellation of thruholes used to make contact? I've been hoarding an advert for a patented industrial...

YAY! storage corral sections of shelf platform nearing completion. Bending warped castoffs to my will. Gotta find my doweling jug, shims won't do it below, but bolts will above. Doweling seems a lost art, rudimentary if exacting woodworking skill and a good, low budget TinkerTip I think...

That! < TLDR > However for me the exercise is more an exploration of the "artwork" that is a Logic Board's routing and "seeing" how all the components fit together within the copper Labyrinth. I can't "see" those connections on a conventional schematic, nor do I grok the code that you navigate...

ISTR there being STIL(?) files released in the 3D Printed Objects thread at the MLA for printing your own?

Morning musing of the day: This section of my Rev.A's HALs ought to be fairly easy to isolate from the State Machine HALs, no? Thinking in terms of socketing that section of the board and doing a PCB that would be a plug in replacement for them? Conversion of their I/O to match that of the TI...

Got pics?

That's pretty much what this thread is, but I think it's probably bett here in the DIY forum. That way I can add stuff as I go along, post projects I've documented in the past as time permits and it'll keep popping up in new posts now and then?

Wondering if the width of your case lends itself to doing a Mini-Portrait Display utilizing one of the inexpensive RPi LCD kits? 768x1024 calling! 🙃

WOW!!!!! :cool: Lovin' it, but maybe I might make a suggestion? One LEM legend is that the Q630 was a rework of the Q605 logic board. You might consider that board to keep this wonderful build Quadra correct? Breaking connectors out the backside presents no real problem. ;) edit: that top...

I love the images you chip de-constructors provide. How many layers does an ASIC like NuChip employ? I'm wondering if my set of HALs might be shaved(?) and imaged for reverse engineering? Reproduction by burning GAL/PAL replacements would entail how much work? What might be the odds of...

Rats, all my in progress pics are on the phone! Here's a teaser, shows my love of the figure, color and knotty textures of wood. I've been hoarding the best bits and pieces from what I've used since I moved down here in 2004, apparently just for this project. The two front rails are shipping...

Update: minor project documented upthread finished! Spade bit countersunk hex bolt head and washer are used where particle board material doesn't meet carriage bolt requirements. As the name implies, they were meant to be used in an application where really solid, tightly grained, first growth...

666MHz . . . perfection! :devilish: I love it, fabulous hacking with incredible fit and finish, the backplane and especially the CD conversion exhibit true mastery in practice of the black arts! 😀

First step, go back to the source. First of series: DCaDftMIIaMSE We've got C16M (AKA CPUCLK?) and /CLK running in and out of this mess everywhere . . . Now to compare this to the Bomarc NuChip schematic and maybe get this sucker up and running so I can measure the rate of /CLK? WAG is...

Methinks @Bolle is already well on his way down the IIsi road. Just before I started bugging you about morphing your LCIII into the Compact form factor I was posting about reformatting IIsi for the SE/30, driving its CRT from Vampire Video at 12" RGB res. ISTR he PM'd me saying something like...

Back to basics: the source of this stream of craziness would be the longstanding NuBus in SE/30 project. So I'm dialing the Rev.A reverse engineering back to the source of its 16MHz CPUCLK to 10MHz NuBus clock implementation for the moment. If that's simple enough, such might be implemented on...

Shades of His Steveness. :eek:

Not by a much. :unsure: Dana's PowerPortable is a modernistic interpretation of another classic frog design study, such could be the basis for this kind of build, but that's tangential. If headed that way the LCD would be larger and symmetrical, but I like the asymmetry of the target design...

They do not require an accelerator, they support a IIci Cache Slot interfaced accelerator. They are perfectly usable sans Accelerator which requires no interrupt. If building a riser for the SE/30, provide PowerCache support, but leave connector and PAL unpopulated and you have a three PDS...
