Cool, somebody else has a Visor! Got mine new in the day. With EyeModule in its expansion slot, it was my first digital camera.

Ordered a new multimeter that should tell me the difference between full continuity and weaker states. Meanwhile, I cleaned up the sticker residue on the solder side with alcohol and discovered that a liquid emulsion gives better definition to the subterranean net. Can you crop, clean up and...

Still waiting for parts, so took a look at the BigROM Bus removal campaign. 1) can you identify what ROM packages fits and find a pinout link for me to run down? 2) figured I’d check traces that may or may not be necessary to keep. 1) Which ROM fits the footprint I measured U25 and U26 in...

Belay my last! I just knew it had to be more complicated than that, So much for a Wikipedia(ick) inspired rabbit hole. @Tashtari has been working on it already! https://68kmla.org/bb/threads/cloning-the-iwm-sort-of.49939/post-563733 /Tangent

Found it! Mini-ITX sized Macintosh Plus https://tinkerdifferent.com/threads/itxplus-a-itx-sized-macintosh-plus-logicboard-reproduction.4302/#post-37135 IWM Clone needed. ;) edit: 128K in SE/PDS form factor and SE/30 chassis for vertical accelerator/expansion card prototype playtime sounds...

May be a tangential rabbit hole, consider the source, Wikipedia(ick) says IWM is a condensed version of D][IC. So wondering cloning IWM from that info might make an all new, off the shelf clone possible with no Apple sourced IC? https://dmcmillan.co.uk/blog/dumping-6309-proms...

I don't know about replacing the front bezel, but it's not necessary and probably wouldn't have been included in an Apple upgrade kit. If it's a late SE, it might very well have the slotted chassis of the SE/30 for its vertical 030 PDS Card setup. But that's the part that would very likely have...

YOWCH! It looks like whatever kinda cage rattling around loose in there was for a 3.5" drive and kept caged under the peripherals tray by its supports? The cards look to be in great shape and an interesting lot, especially if you're into music. Welcome from a fellow forum dweller! Sometimes I...

Cool, you were doing exactly the same thing my son was doing in that time frame and your son is doing the same forty years later. Not today exactly, but it was about 1:00AM today until I finished up with the speaker extension. I got the SE/RadiusFPD/MagicBus put together and tested it to the...

IIRC there's a way around IWM for startup w/o FDD access in POST?

Interesting notion. You can make it with almost all off the shelf components?

Thanks much, got frustrated and just ordered one that looked like it might have all the features I wanted for a starter unit. I've had a few analog meters over the years and a cute little digital from Radio Shack from about 1990 that's still great. Battery powered was a must I HATE USB...

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...

A clear benefit to the seller of collectibles (in general, not just our obsessions) with wildly inflated prices that are verified would very likely be money laundering activity. Self dealing on things like vintage cameras, lenses and whatnot are often efforts to keep sales pricing high overall...

Was searching on Dudkduckgo and got this info: I don't see anything from your DuckDuckGo search. Nothing came through with your message: no pasted text, screenshot, or attachment. Could you send it again? Any of these will work: Paste the text into the chat. Attach a screenshot. Share the...

I missed this effort as well. Not in the market for one, but can't believe I didn't see it posted. DuOh! :rolleyes:

Heh! Checked in with Duckduckgo with an initial question and followed up using the GPT-5.6 Luna search assistant: What Are Inner Layer Traces? Inner layer traces are conductive pathways embedded within the internal layers of a 4-layer PCB. These traces are crucial for connecting components...

Thanks @JDW Very interesting comments about workflow there, but . . . Definitely headed toward KiCAD, but only after a few more steps. Illustrator suffices for Claude assisted schematic capture required for that platform. For that I need a pristine scan of the solder side of the board, bullet...

The pics Claude couldn't access from ImageShack: Much confusion ensued. Adapter facilitates reconnection of FPD card to SE PDS after PITA connector removed from solder side of FPD card. That's necessary to get a good scan of the solder side: Once I have that clean scan and you confirm...

Thanks much guys! I'll report back after I get the SE up and running.
