Portrait Display

[falen6]

Did it again , took something down from the attic

This time it is an LC iii - when i opened it there is a radius pivot color display card inside

Cant remember when i got the machine , but there is also a portrait display up there so took that down as well

Recapped the LC and its working great

tried to connect up the portrait display but ive never seen this connection before

ive never powered up this display either , know nothing about them , looking for some advice folks-

why are there 3 ADB ports on the back of the portrait display ?

What exactly does the radius card do , remap the display to fit the portrait display ? .....does it help with graphics ? .... why is there a ram sim on it ?

after some searching the cable i need ( i think ) is a db15 to 13w3 ....... only one i could find is 100 dollars !! , between insane shipping and import charges in ireland these days will prob be the best part of 200 dollars to get to my door

would it be worth the effort and cost to restore this monitor ?

cheers folks

You don't need the card for the Apple Portrait monitor - the LCIII onboard video supports the 640 x 870 resolution natively (using the 13w3 to Apple DB15 cable). Keep looking for that cable in your attic! It's heavy, thick and might be there!

Other things:
- The ADB ports on the back of it act as a passthrough, not seen on many Apple branded monitors.
- The Portrait monitor is very rugged, over engineered and even has a fan inside it. Take it apart and have a look, unless anything looks really dicey/covered in thick dust it should power up. There are no big weaknesses unless high hours and caps worn.

Thanks for that Byrd
Already was up there looking for that cable , no luck so far

will pop the rear cover and have a look

if the lciii supports portrait display then what does the radius card do- was hoping it was some kind of acelerator card , but with drivers installed the graphics benchmarks are lower than the card removed........ what does the card do !!

Fingers crossed that cable is there - I've high hopes for you! And you need that one, the Sun or generic equivalents have a slightly different pinout.

It would support the Radius Pivot monitor - the one you swung around during use for vertical (Portrait) or horizontal mode. I don't think the original Macintosh LC supported Portrait resolutions. And, dual displays I suppose as most Pivot cards support standard monitors. Presume that's a VRAM slot there for more colours, and socket for FPU-less '030 pizza boxes.
