Very cool, what's the video output refresh spec? Plays well with multisyncs or 60Hz VGA? ISTR an available Molex assembly that can be clipped and hardwired to the adapter at a convenient length rather than setting up to use the stubby stock harness? Gotta get my hands on one of those puppies...

Forgot what you'd said upthread or elsewhere? That Video/ATX PSU adapter would be for running the board/accelerator in a bench test config for the moment? A dedicated thread for setting that kind of thing up would be great. WAG here is that you could set the board up behind an LCD on the...

Kai posted this reason for your unpopulated components. ATM you appear to have a pair of 520s with + upgrade in waiting. That would be my understanding anyway? Curious about that upgrade, would the memory loadout be the only differentiation?

Confused about physical location for Video/ATX PSU adapter? It's not in a standard breakout board form factor? If you do a breakout version, be sure to add a WiFi antenna mounting point. :)

Someone at the MLA was doing something similar and I turned him onto that existing LCD housing. Hadn't thought of it. He did some really nice work. This was quite some time ago, I probably have pics of the model. Don't recall shared files, don't think he ever finished. Nifty stand . . . now...

Nice to know we've got a few of these in good hands. I've only seen a little of the die imaging info out there. I've seen some of the gorgeous stuff Siliconinsider has done. How many folks are tinkering with exploratory die destruction? Lots of interesting info popping up in this thread, is...

Methinks you should post a new topic about Brainstorm. I'd forgotten about it. Reverse engineering the function of that proprietary "bus accelerator" will be a great topic for discussion. WAG here is that it might be treated as a Black Box and implemented on current hardware with open source...

Still haven't buzzed connections for the pinout you requested, LMK if you will need or want it. /PDS Tangent

Been ruminating on this one whilst doing other things. It struck me that the VRAM SIMM expander only needs to support a 256K SIMM alongside the 512K SIMM as the 256K Bank on board will remain to complete the loadout. That would simplify things quite a bit in terms of bodge line requirements I...

Here you go, Zane. this is a rough-in of WarpSE version of what I'm planning for an SE/Plus specific rendition of Performer/32: Move your WarpSE over to the side enough to fork PDS connections over to Accelerator and up to proposed Radius MagicBus based MagicBus+ thruhole implementation. It...

Might not really be that bad. Bad info about Quickdraw support in this LEM workup, but interesting piece of equipment and a much more simple software hack for that kind of tinkerer hereabouts: https://lowendmac.com/2013/scuzzygraph-and-scuzzygraph-ii/ Take apart the drivers for printing to...

No such luck for SE, single bit limited on the video front. :(

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...
