Genesis of this topic was five years ago and things have changed quite a bit in this market. https://tinkerdifferent.com/threads/multimeter-recommendations-auto-ranging.652/#post-4471 Couldn't search up any newer threads on topic so if you know of one, please post it here. @Branchus love your...

I'll edit in the other threads leading to this at some point. It's a Cloning Project of the 1086 first gen 64/68Hz version of Radius/SE Card. Card is built in discrete 74LS Logic and readable GAL20V8 ICs. Pre-dates the second gen card with unreadable ASICs. TPD card is infested with same, so...

Unsure this is the right place to ask, but setting up 4 "identical" ProBooks for three docks scattered around the place. One' ProBook's a bit borked, but its I7 is heading into my original Cherry I5 ProBook at some point. Wondering if the ProBook will "just know" that it's been upgraded from...

Pulled this Card/Adapter out of storage to see if it might be a cloning target. Found my old thread about this one over at the MLA whilst searching for info on it: https://68kmla.org/bb/threads/e-machines-big-picture-card-w-mac-se-interconnect.32335/ Does anyone over here have one or seen info...

Some folks have been wondering about what I've been posting in another thread I've been using as a Development Notebook, so here goes: Developing a carrier board to interface with the first gen Radius FPD/SE's four VRAM Chips. They'll be de-soldered and then inserted into wire wrap...

I've got a test rig that'll boot Alchemy and Gazelle boards with no problems at all, but not my AIO 5500 sub-variant of Gazelle. Does it fail to POST due to lack of internal CRT hookup or might there be another issue with this particular board? If display is indeed the problem, will it POST...

It's Alchemy Architecture, not Gazelle in which this card is problematic without the Great Gazelle PCI Fix. Makes no sense to me unless some PCI equivalent of DeclROM in a NuBus Mac is present? Any suggestions?

@luRaichu jumped into the project with both feet. He did the board layout, ordered the PCBs, the components, assembled the first one and it's in my grubby little paws for testing! All goes well so far outside of playing whack-a-mole with the gremlins actively undermining my attempts to get a...

. . . hopefully! Start of this project was info about the anemic TAM PSU issue from many sources, here, MLA, WWW and ThinkClassic back in that day. Was working on putting together a better Initial Post, but what the heck . . . just chuck it out to the pack of wolves! :p First notion was...

I've long suggested contacting woz to see if he'd release (or recreate) SWIM for the community: We're of an age and thinking it might be a significant addition to his legacy. He's far deep into education and tech talent development thru woz.org. So thinking would be that giving folks young and...

Wondering if a hookup or workaround for running an external antenna lead outside the RFI shielding of a Mac is a possibility? Running the lead to a wire type antenna in a PowerBook lid might be ideal? RFI shielding of a Duo's HDD bay can be tucked underneath, but dunno about other 'Books? Also...

Retrieving a 9 year old project from the pile-o-procrastion on the top shelf of the rack doesn't constitute the necro nonsense Resurgence in obsessive/compulsive leanings here could be mania inducing, gotta watch that. This was brought on by tangential happenings in this year's Marchintosh...

Confusing original post. Will have topic title changed for clarity, skip to: https://tinkerdifferent.com/threads/pci-riser-design-rework-of-github-pcie-riser-howto.5191/post-45946...

MacPortrait appears to max out at ancient TPD resolutions. Is there a current solution? Windows and Ubuntu have had me spoiled for the longest. :rolleyes: The last time I ran a second screen in that orientation on a Mac it was the Macintosh Portrait Display on the 2300c/DuoDock+ next to the 21"...

I've been watching the Budget Oscilloscope discussions . . . https://tinkerdifferent.com/threads/budget-oscilloscope-recommendation.4590/post-39614 . . . but have a problem with spending 10% of the cost of a much more capable medium range O-scope. Budget jobs appear to top out at working...

Found out yesterday that the battery in my Radius 81/110 leaked at some point in the last couple of years. Doesn't appear to have exploded, though I can't get to it for another year or so, in week nine of rotator cuff surgery and that thing is well and truly buried! I'll be able to lift the...

Thruhole PLCC68 sockets seem to be available. Is this what folks have been saying is unobtanium? https://www.ebay.com/itm/235031138033 There seem to be a few listings for thruhole sockets and plenty for SMT Socket listings. The sockets on Performer boards for the Classic look...

Wondering if anyone has seen AI used to crack protected programmable logic? Target chip is the PLDC20G10 on my current obsession, the Radius FPD for Mac Plus. https://media.digikey.com/pdf/Data Sheets/Cypress PDFs/PLDC20G10B, PLDC20G10.pdf 24pin DIP IC provides up to 22 inputs and 10 outputs...

Figured I'd just ask as it's been over seven years since this pic kicked off the clone game in the MLA Hacks Thread: So is the stock 68000 CPU necessary under the Killy Klip in my Drexel Plus or could the Performer (or other, more complex accelerator) be plonked onto a socket installed in its...

Does anyone have this VidCard available for a photo session? It's Radius' first product and one of the very few Radius cards I've yet to collect. Got TPD card for SE in hand and the BT9014 on it appears to be the only problematic Programmable Logic on the board? NuBus Mafia appears to be down...
