SE30 came with a Lapis PDS/30 Full Page card


Recommended Posts

Fellow Compact Mac Aficionados

 

I recently purchase an SE30 and lo and behold, inside was a Lapis PDS/30 card but just the card alone. This looks like a TFT card, I think anyway. A 1 bit card perhaps.

 

I checked my archives and I do have Lapis software but I don't believe for this card. By the way, I am happy to share the software drivers with anyone who wants it.

 

Does any know know something about this card? Does it require any additional software and what about a dongle to attach it to a display, can I make my own or did it require something special. Kind of blank on this one.

Thanks for any and all information. I appreciate it in advance.

 

Kind Regards

Alex,

I have the exact same card and IIRC the driver is called 19" Init. If you need it, let me know I'll send you a link. 

It came with my SE/30 too. I immediately replaced though it as I didn't have any compatible monitors, so I don't know for sure how it works but I'm sure it's at least a 4 bit greyscale.

Yep, needs a "dongle" for backplane output. Thankfully, every breakout "board" I've ever see for an 030 PDS VidCard has been a simple metal backplane plate punched for Mac Video output via IDC DA-15 connector bolted up to the cutout with matching IDC 16F plugged onto the VidCard's headers on that end of the ribbon cable.

 

The only variation I've seen would be my SuperMac card that has a an IDC 16 connector soldered right onto the card. You'd have to cut the cable to lose that  breakout connection.

 

Modeling an 030 PDS backplane plate for 3D printing might be a worthwhile project. Modding the blank for customizing cutouts in whatever positions desired for any number of oddball connections would be duck soup.

Would you mind posting a pic of the backplane for the card and the software if you would be so kind please.

Ahem. My apologies, I don't have a full page card but a DPD one. It has the same layout and they share the same PCB but I noticed a couple of ICs are different. Not only that but the video out is not located at the same place. Mine's is located at board location ECL-1 (J5) and yours appears to be over at "SPD" (J3)...

I am working with the Mac SE version of Lapis DisplayServer and have the backplane and card installed.  I saw a post that said it should run on 7.1 and I am able to get a control panel I got with the board to load and set my main screen / secondary.  But on my secondary VGA it shows a valid VGA signal (wakes up and resolution is right) - but it is all black.  Could anyone share the specific driver set for Lapis so I can rule that out ?  I looked all over today and kept getting a bad archive.

You can interface the card shown in the original post to a VGA-style multisync monitor using the ECL-1 connector.

All you have to do is add a 100ohm resistor at R13, which will give you a video signal in the proper voltage range (if wired up in parallel to red, green and blue) for VGA monitors on one of the pins on the ECL-1 header.
