. . . title says it all, but a lot of different projects intertwined. I've long wondered about stuffing something interesting into the FDD bay. Big question would be whether or not a PowerBook can be convinced to act as a display for Pi5 via SCSI input. That'd be a ScuzzyGraph in reverse...

Same here, but a brand new, remaindered PowerBook 100 was my first laptop (notebook) computer and I still madly in love with those in my collection. Nothing like the 100 until Apple demo'd the Duo System at a NYMUG meeting, but I thought I'd never be able to afford one. I only switched to a...

If it's no biggie, could you further explain the ramifications of that differential for the project? What might be done to rectify any such problems? Don't want to throw us into an unnecessary tangential discussion.

VERY cool! Was thinking along these lines a LONG time ago, but back-burnered because I wondered how the flex switches differed electrically from mechanical switches? Might there be a problem with such, if so?

@max1zzz thanks so much for the layers of your IIcx Redux. I've reconstructed the traces/chips/pads for the three signals that meander down off NUCHIP in the NuBus section of the Bomarc Schematic. Trying to figure out where ARST, LO0 and HI0 go and what they are doing? Some of the circuit...

Got the NUCHIP .PDF to work!

A little last revision eye candy in the case that NUCHIP injection proves impossible: Clean slate for the Radius IIsi NuBus Adapter rework approach: Form factor is frozen and in the can! Here's proof of fitment and the card I'd be tempted to use if I had 040 Accelerator and GS Cards...

Done playing with form factors, time to get on with the technical hurdles: First approximation: I was hoping that patching the three VIA2 signals to the three reserved pins on the SE/30 PDS would be sufficient. Out of curiosity, are those pins grounded. Can't find my continuity tester ATM...

Just ordered the PGA adapter, so I can get started with manual board layout once I'm sure of the pinout! :) PGA Socket supplier has a $30 minimum purchase, so I've a bit of shopping to do.

I found a couple of interesting tidbits tonight during downtime at work: https://www.proto-advantage.com/store/product_info.php?products_id=4610006 https://www.proto-advantage.com/store/product_info.php?products_id=2620006 I think this might be the right size, less the four corner pins it...

Quick questions: Can't remember what package type NUCHIP would be called? Has anyone seen an adapter from SMT to thruhole for it? Kinda like this one for QFP: https://www.ebay.com/itm/252818521461

Installation of that big cap looks reall ugly, should I assume the board has been at least partially recapped?

De nada. ;) More pics for perusal at work in downtime tonight: @max1zzz any chance you can send me the remaining layers of the IIcx board to use as templates in AI. I won't post any more than the above. I'll ask here as well: NuBus and PDS passthru will be split into a V configuration on...

Yep, this'd be the current Rev. 5 of Project30 over there: https://68kmla.org/bb/index.php?threads/project30-iisi-nubus-adapter-in-se-30-fifth-edition.44861/post-493049 I should get a single slot up and working via the NuCHIP wedge, board production is surplus/damaged donor board limited...
