Can't tell you how much I'm impressed by both your design and installation throughout. I spent a couple of years dong Kitchen Design in a Big Box and can only think of one suggestion for you. Being an inveterate tinkerer/sometimes professional in many related fields including the design and...

Thanks, that's what brought my notions back closer to the fire. :) Took one glance again and now am wondering how flexible the thinnest single sided PCB might be if cut in a comb pattern dividing pads for flex-contact up along IC legs with RA Headers installed in the thruholes pointing...

Never thought of that. 🤔 I have a beautiful set of Japanese pull saws for that kind of detailed work. But it's a rough cut kinda thing, an extension to the wood/plastic/metalworking power tool bench sitting opposite under the two corner windows of my apartment's living room. You can see one of...

Very curious to see the differentiation between the two cards. Given the info I posted, I'm willing to bet at least a nickel that the 2x5 header is single bit resolution over an EGA connection as mentioned in that product intro article. 🤔 https://old.pinouts.ru/Video/EGA_pinout.shtml

Might that be the one mentioned in a thread over at the MLA? ISTR the designer saying it was a one use kinda deal at the time. I posted that first pic over where that was mentioned. Like I said, nice community project?

I like to keep mine close at hand in the work areas. These are stacked nicely behind the two sided, tucked under the shelves general purpose workstation. Front side looks better, now it's a neat lineup of compacts across the front, a couple tucked behind along with a baby Pavilion. Pics...

Been a bit, but just ransacked my MLA pics archive. This is what needs replacing with something more workable for the 10cm Square PCB era/card development era. That was a wonderful, fairly mass produced kluge at the time, but not doable in a short run in this day and age. Besides, it was a...

More info from p.44 of the 2019 archive I did of my MLA attachments.***** So those connectors may not be what you had though? Treat the center section of that 2x8 header as a VGA HD15 breakout to see if the stars align? Don't recall the issue date of that article, but the year of Lapis...

Let's start with this curiosity? I see what looks like an ISA Standard Cable for a Multifunction I/O Card's breakout, but it's not and it's seemingly very strange. Don't recall a DE-9 cable hookup with 11 IDC signal lines implemented . . . ever? 10th pin on header is for D-Shell ground...

How about posting a pic of your card here for this Whiskey Tango Foxtrot degubbing session? Which version card(s) do your guys have? I now clearly see two and three interface header connector types on the two prototype setups. So many puzzles here . . . playtime! 🤪

Revised edition answer: Any Control Panel for multiple displays for SE and earlier Compacts pre-7 will be third party IIRC. TLDR: Going through the thread I picked up on that bit I had addressed, but a little context never hurts? Radius developed the first version of such a control panel for...

Congratulations, great to see it coming to life! :)

Sorry, visual thinker here, so sillyscope experimentation results and conventional shematic diagraming only compute with much too much effort if and when they do in my noggin. I can "see" the I/O flow of systems, but it's more like a plumbing/hydraulics blueprint the way I process things...

That would be the answer to my question, which was badly put. Looked, but didn't see a picture or diagram of the PCB with the physical location of the connector types labeled last night. I was the one who suggested the Extron Scaler. ;) TTL would need to be converted to an analog signal, no...

Which connector are you using there? That's an analog signal? That's the funkiest looking thing I've ever seen using that scaler?

Definitely save SCSI mass storage solutions for IDE deprived Macs. I run my 6400/6500 TinkerTestbed off CF/Adapter and it works great. SCSI internals was not only easier, it was necessary as IDE support was rudimentary when introduced in the Quadra 630 and PB190. It hadn't improved much by the...

I see one connector is for TTL, which answers the question with which I was coming back, some TTL interfaces used the DE-9 connection for Black and White Displays IIRC. Hopefully yours is analog on its proprietary DE-9 interface? Wondering about the relative cost of the Ehman CRTs was eating at...

This is an SE card we're talking about correct? No, you can't and that DisplayServer PDS/30 ain't gonna fly on the SE no matter what you do, that'd be for the SE/30 version of this contraption. Did any of this stuff really ship? I have no idea what any of the other headers are doing on that...

Well there goes that notion, it's an available, supported product, definitely not something to be public licensed for hobby use. :( https://www.extron.com/product/rgbhdmi300a Gotta give it a try at Component Video to HDMI, my TV is HORRIBLE when it comes to that.

Which lines from the logic board harness are you connecting to what & where? A diagram of your hookup would be most helpful in troubleshooting. There's an ancient setup for building the CatMac/Hickintosh floating around, checking against that would be my first step. There have been fairly...
