Can't imagine there'd not be a performance hit, but how bad might it be? Duo2300c would actually be the target machine. Pretty much same machine as 5300/1400, but with SCSI HDD option (supports SCSI HDD/Cable in upgrade package config) but no PCMCIA availability. So curious . . . for a...

Don't wanna tangentially muck up the fabulous IIsi into SE/30 thread that @zigzagjoe has running over at the MLA with this craziness. @Bolle posted parameters of the conversion problem. _______________________________________________________________________________ The Apple 12" 512x384 video...

. . . yet again as once more, this is way above my pay grade. :oops: When spec required 5V for LCD and 12V for Pi/CM4 board, notion was to use a PicoPSU and its AC adapter. Figured I only needed current limiting resistors for those two Pico lines. Now I only need 12V input for both, which...

PowerBook 100/2300c LCD/Logic board upgrade has been in process for well over a decade. This revision has been on the back burner since the Compute Module 4 first came out. The I/O board makes it perfect for this upgrade of my beloved BabyPB, very first laptop, bought new and maxed out in the...

. . . to raze the malignant dining room table monster. Can now concentrate more clearly on the real world hardware phase of a long running obsession. :p

. . . and the mythical no more: Slot C for Alchemy! Cleaned up baseline research, reference condensed from posts in multiple threads on three different forums over the past 5 or 6 years. Thanks to all who've helped out in the seemingly interminable research phase. At long last development...

Procrastination pays off handsomely! http://mess.redump.net/mess:driver_info:mac_technical_notes I imagine this one is in use by the boffin brigade? But others might want to take a look.

Been dreaming of this one for years, got a low shuttercount, mint body from Amazon Renewed. Straight flippy screen is the key feature added to baseline requirements of full frame sensor and compatibility with my extensive prime lens collection for my early production Nikon F collection. This...

Dunno, hoping I can find the critter somewhere around here. Snagged a UMax SuperMac C500 CPU 603e 180 MHz Module fourteen years ago and haven't gotten anywhere with it as yet. Started looking at grafting it into my 2300c some seven years ago, but the bus multipliers didn't seem to give it much...

Looks like it boils down to card connector availability. Anybody know the spec or source offhand? Crazy notion popped in the noggin' for the fabulous Compact Flash card for 030 PDS @zigzagjoe has in development over yonder. Figured someone here might have the answers. Tech chops here far...

Remembered my early SCSI II card whilst slumbering in bed and tossed the notion of cloning it out to the gang at the MLA before I woke up enough to think better of it. So here goes: Wondering if anyone here has any notions about what might transpire on what appears to be a fairly simple...

Main thrust of this will be my beloved first laptop, bought new on clearance PowerBook 100/maxed out memory card and faster modem card from APS. Stuffing it with CM4 goodies resumes ancient project after first take now abandoned. Have to find one more box with the base unit inside. But stretch...

Cannot catch a break with this one, then two and now today three machines. Win11 borks the third display over DVI on the dock. From the beginning: ProBook #1 - got the i5/16BB version and was happy enough with it. Display is 1080p as expected, was willing to spend $200 on Amazon ______________...

@Androda got me entangled back into the web of CSII/PCI insanity with his amazing CSII 10/100 card project, so spinning off the tangent. Genesis of the Quest for the 3rd PCI Slot in the 6400 Alchemy architecture over at the MLA some six years ago: "In another thread, @trag mentioned that his...

I've got a two channel ATA-133 setup on my TEMPOtrio and would like to set up striped RAID 0 on a pair of DiskOnModules. If SoftRAID won't work with ATA-133 are there other avenues of approach? It's too bad Sonnet didn't set the card up for hardware RAID? 😕 edit: what level of SATA is...

From the pics I have on hand, in terms of size the two(?) parts seem easy enough to be printed? Repro FatBack would seem to be in some demand I'd think, many are missing and unavailable in the wild? FatterBack version would bow the curve of the hump out a bit - providing more overhead for...

I've identified available cubic in the TAM for boosting its anemic power budget in the upper right hand corner of the red box: edit: found a far better pic of available cubic: A PicoPSU will fit nicely mounted vertically to edge of the ComSlot2 standard riser with hot glue or socketed on...

This insanity started just about 5 years ago: https://68kmla.org/bb/index.php?threads/twin-pci-riser-project-for-tam-6360-5x00-single-slot-powermacs.31437/post-335299 Best explanation: TwinSlot Riser for TAM & version for 6360. Looking at having a USB connector and a 12v in jack for...

. . . 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...

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...
