E-Machines Big Picture Card with Plus->SE adapter board . . .

.  .  .  available ATM for reverse engineering! < AWOL EVIL emoticon inserted here >

Dunno, the the Mac Plus adapter isn't included in the SE package, but the Plus -> SE conversion has got to be useful for figuring out how to interface various goodies to the likes of the Luggable PDS or olePigeon's quest to demystify TTL TPD sleight of hand hacks to B&W(VERY limited GS) architecture Macs.

Reviews and pics of the "nested" Plus & TPD along with lots of good info in reviews of all available solutions for FPD/TPD at the dawn of the DTP Age.

https://www.google.com/search?tbm=bks&h … PICTURE%22


My guess is that the IC will turn out to be a termination pack, but the DIP header to EuroDIN96 PDS adapter looks to be a customized platform for prototyping Compact Video-Out projects to me. Why limit a CVO solution to a pathetic compact pixel count?

I'd bid, but such feats are well beyond my ken to begin with and  I just sent most of my current (pitiful) toy budget his way for a replacement for the IIsi MoBo that I managed to nuke anyway. roll

Somebody snag this stocking stuffer for yourself and get with that program! smile



p.s. still good info to be had right there in the (already archived) auction pics. wink

Re: E-Machines Big Picture Card with Plus->SE adapter board . . .

Hmm, I don't see anything about a Plus -> SE conversion or a Mac Plus adapter; this looks like a regular Mac SE video board. What am I missing?

Re: E-Machines Big Picture Card with Plus->SE adapter board . . .

Take the two PCBs apart in your head along the inter-board DIP connection. Left side board with components plugs into something along the lines of the MacGusto or KILLY KLIP accelerator adaptation for a 512k/Plus gen rig circa 1986/87.

From Google search linked: Pics, Reviews, vague memories of the day and such, I've surmised that the DIP -> SE EuroDIN PDS adapter card was whipped up upon the SE/Macintosh II rollout. I could be wrong, but it makes a world of sense to me the way the timelines and technologies mesh for E-Machines to have cobbled up an SE PDS adapter for the mature,  pre-Slot Manager hardware already in production. They assigned all talent available to the BiG Picture II NuBus Architecture development team. VidCards were their vehicle for shipping Displays, their raison de'etre.

Given the limited data and addressing requirements for B&W/phantom4-GS compacts, the 64pin DIP header sufficed, likely into the 16bit I/O arena, certainly into an 8bit SCSI controller I/O wedge.

Curious, I hadn't realized that only radius was capable of pulling off the two-screens on a Compact hack, no surprise really, but still a pleasant one. wink


p.s. on second thought, if we're VERY lucky, the DIP on the backside of the SE Adapter just might turn out to be a priceless early DeclROM/Driver example as a feature of that cute lil' kluge! yikes

OMG! Thank you! big_smile  Just take a bunch of pics for now, let's get it into the hands of the just the right person to get something built upon this interesting little wedge between the worlds Compact. That's the greatest gift of all in regards to this, for all of us to share. wink

Re: E-Machines Big Picture Card with Plus->SE adapter board . . .

cool Me likes collaboration!  I can't believe olePigeon isn't signed up over here yet. I just invited him into this little party specifically. ISTR he's been trying to determine the pinouts of another TTL output SE Vidcard. This one has them labeled right there on the silk screen layer. Dunno if he's got a SillyScope yet, but he's be the likliest to wring some info out of this ASAP. Me, I'm sans SE, which I'm now glad I never mentioned! wink

Now If I could get somebody to ask me a few more questions in the Daystar Aadpter Cloning thread maybe I can get the line of reasoning across. Me loves exploring hunches based upon scant evidence.

I'm not the guy who can find patterns in the chaos, I'm the guy who spots the four leaf clover in the middle of the exercise yard at Dorothea Dix without even noticing the vast swath of normalcy surrounding it. When I explained that to my Psychologist there, she said she'd never found one. So I said I'd bring her one and I had the aid time me: a little over two minutes when looking through a patch of clover intentionally  .  .  .  musta been a sloooow day. hmm




edit: Have I ever mentioned that I'm crazy? Though it's one of my greatest blessings, manic-depression isn't the half of it! big_smile

Re: E-Machines Big Picture Card with Plus->SE adapter board . . .

I don't have an SE either LOLOL big_smile

Yes, hopefully OleP or someone with some experience with these types of things will show up. In the meantime, I'll keep the bugger safe and sound. If anyone shows up to this thread and wants any info, I will do what I can to provide it.

And as for 'crazy' talk, I suppose it's been suggested (for ages!) there exists a strong correlation between creativity and people who gravitate more towards the extremes than the middle. My personal view- The world needs all types, and I like those who are out there looking and finding the four leaf clovers amidst the normalcy.

Re: E-Machines Big Picture Card with Plus->SE adapter board . . .

I don't have an oscilloscope.  I did have some progress with the card, though.  I got a signal out of it, but it was all screwed up.  It's definitely an analog signal of some sort.

If anyone has an SE and an oscilloscope, I'd be happy to ship them the video card.

The Eagle has landed! That's about all the Eagle can do at this point. big_smile

jt, here are the pics I promised. If you are anyone else want any more, let me know. This card will remain in stasis until someone wants something of it.

Re: E-Machines Big Picture Card with Plus->SE adapter board . . .

Sweet pics, sounds like a plan. Thank you for that Christmas gift to the 68k Development Community, MJ. You've just gotta love those simple two sided PCBs from back in the 8MHz day! smile



p.s. do those traces look as much like the pinout for an inverter/driver DIP to the knowledgeable as they do to me?

Does anyone have any pictures of the Plus adapter? I'm real curious as to what it looks like.

Great question, I never realized that card lacks the thru-holes needed for Killy Klip install.

Re: E-Machines Big Picture Card with Plus->SE adapter board . . .

Hehe, I HAVE this card (SE version) inside a hacked up MacPlus (I fried the analog board a loooong time ago).  It now features an MacSe motherboard, the Big Picture card, a fan, a PC power supply and an internal harddisk.

And I have the E-Machines Big Picture 17 inch monitor.  It has an asymmetric rear, which allows you to snuggle the mac to the back of the screen, showing just enough so you can still use the floppy port.

Only I lost the cable, so the Big Picture does not show it slow-phosphor greatness.  The slow phosphor was a great feature for games, made the action really smooth.

Ran a hacked version of Word 4 on it for years, still the best version, with all the formatting options in one menu, including the section options.

Killer combo!  Anyone have a spare cable?

Re: E-Machines Big Picture Card with Plus->SE adapter board . . .

If you mean a cable from the card to the monitor, then sadly, no, I don't... I didn't even know there was a specific cable until you posted... there's so very little out there regarding this card!

Do you have the software for this card? yikes

Re: E-Machines Big Picture Card with Plus->SE adapter board . . .

re cable: Very specific.  one end is db-9 (as shown in the second picture). The other end is a bit more exotic. While it still uses the db9 form-factor, it has a coaxial connector in the middle (a bit like the old color diaply cables, only those were a lot wider and use three cinch connectors, called DB13W3)

re software: I should... If the magnetics haven't decayed by disuse... Currently the system is in storage. I'll try and recover.  PLeas ping me if  I haven't replied in a week.

Re: E-Machines Big Picture Card with Plus->SE adapter board . . .

Coolness! Welcome aboard, larsberntrop.  Cable shouldn't be too hard to reconstruct. I've got half a Sun cable and plenty of other junk to donate to the effort. It'd be simple for me to cobble together a jumper wired, configurable test cable. smile
