I'd check SE/30 against FDHD release dates first. Then make a general request for SE serial numbers of both types of chassis? Yep, MLA member donated one to the cause last week! Said he has stacks of sheet metal gubbins.***** Given the low profile of current SMT components, Zane's proposal...

There's a documented method for reliable QFP conversion to BGA from back in the day out there, but not posting about it in open forums. :p

Not sure what you mean by that? PCB is in the one existing slot with both SIMMs on board. Pads are vacated and only the CAS/RAS control line bodge wires are soldered to them. IIsi is a PITA as the data bus is disjointed on the controller. Otherwise I'd be using adapters in the existing SIMM...

Definitely, sick indeed! :p I've been looking at doing similar things with Macs hobbled by undersized banks of onboard RAM for years. I wonder if the approach I've been pursuing would work for you? Instead of stacking Chips, remove them and build a "VRAM SIMM Expander" for the single VRAM...

Ah, you beat me to the post. Any chance you can snake the lines from various locations within your current layout up to MagicBus locale? Overlayed copy of WarpSE pic was scaled to within a percent point of matching copy of Radius pic from NuBusMafia at 'fritter. Something doesn't add up?

edit: @mg.man Wondered about that myself, but decided it best that SCSI->Anything should be atop the chassis. Especially when SD is involved. as you won't really wanna have to be pulling the mobo/accelerator to change out media, no? Better to provide a PDS passthreu for use above the deck as...

Calls for yet a larger PCB, but well worrth considering. The MagicBus Adapter Card wasn't full width SE spec, co heading straight back with your PCB might be better than spanning the width of the case?

Interesting, I only know of the two versions, with and without SE/30 PDS expansion sidewall provision? Nor have I ever seen an SE PDS card meant for vertical installation through such an opening. Radius Accelerators and MagicBus adapter cards made provision for their FPD and TPD Vidcards...

Can't imagine it coming anywhere close to the 16MHz Mac II and SE/30 family even at 32MHz, which MicroMac never offered BTW. That would have been the realm of mid and high level Perfomer Models with added features like cache and SIMMs IIRC. 32MHz is a "because I can" kinda thing, not sure how...

PDS Card? The only way I know of to do Accelerator + PDS in an SE would be Killy Klipped accelerator and verticalized PDS Card in Late SE/SE/30 Chassis. Bolle has done that and I'm planning to. As for widening the card, I wouldn't bother. The multi-machine supporting Performer worked just fine...

Too late: suggested that you not populate that second bank of 30pin SIMM connectors over yonder. With PiHat headers we can test the 72pin SIMM conversion on that lovey bodge wired prototype. After you've got the board sorted out, desoldering the connectors/ bodging headers is likely more fitting...

OLPC! Love it, so jealous.

Very, very nice, max. Can't wait to see your KiCAD schematic develop from this layout. Thinking about the Streeetch Limo IIcx proposal has been killing me. :p

Oh, what a difference a FedEx delivery makes! 🤪 Pic on screen shows what I bought that BigAss toolbox topper for, note the two ground connections to internal power strip. Hot Air Rework Station, Soldering junk and tools on a drawer slider extended work surface. Roll it back in and drop the...

What's a trophy? Found a before pic of main setup, KVM'd for OS9 AI work, Win10 Notebook and Win98se playtime on Clonish cased Dell Dimension. Pre-flood, heavily tinkered extending/pivot mount setup of 42" panel pointed out toward bed for movies, over to Hack Hutch for playtime over to...

This is about as neat as the Hack Hutch has been in quite some time, so it's hidden behind the temporary desk setup. :p TLDR: Bare concrete is courtesy of the landlord's water heater, desk setup should be on the left of the rack. In moving bedroom to master suite my main display appears to have...
