ultimate SE/30

[uniserver]

hey genie, for now its mega simplistic.

basically this IIsi video card, had to be modified in order for it to fit in the case.

So i loped a controversial hunk off the card.

It just so happen to not kill anything.

The only other thing I did, is the video card didn't come with any Cable or db-15 video connector.

so i had to solder that IDC cable to the card header and then to a de-soldered db-15 from a killed LC that i had laying around

from GUAM , the bare main board sat in a shed, the guys home was right on the beach too needless to say this LC board had rot worse then anything i have ever seen

Anyways, so after i loped the hunk off the video card, and made that video cable. I popped the Video card onto the Maccon network card, because there was no physical way the video card was going to fit directly onto the PDS of the SE/30.

Had to remove the HD/floppy cage as well.

then all i had to do after that was turn the computer on and see what happens. and with out installing any software just running 7.5.5, oh and with dougg3's IIsi Rom simm installed.

The video card just works. The dual screen feature just works. The internal CRT automatically became Display#2. and the out put to my LCD screen became Display #1

as to the Grey scale… i have no idea of those in's and out's, you are saying we will need to add more transistors in order to display more then one bit, would it be 4bit's for 256 grey scale?? Maybe that is something techknight over looked?

if you would like to work on the greyscale project i could send you one of these iisi pivot cards with that kbd and mouse you also need.

I would think once we come up with a grey scale solution i would say it should be worth at least 500 bucks.

I mean that is half the price of the Micron Xceed solution that is being sold currently.

So you didn't have to mess with connectors on the analog / logic board?

Ok I think I get it now...so the internal 9" is still driven by conventional logic board / analog board combo as normal (display #2) and the Radius vid card drives external LCD (display #1).

If that's true than I guess we're nowhere nearer a grey-scale mod then before unless we get video signals from display #1 into the existing analog /video board and configure them so they'll work with the internal electronics (is there any way you can fiddle with resolutions in the control panel?).

as to the Grey scale… i have no idea of those in's and out's, you are saying we will need to add more transistors in order to display more then one bit, would it be 4bit's for 256 grey scale??

IIRC for grey-scale you need to drive the electron gun with different voltages, the B/W compacts have just two settings, off for black and max voltage for white. The signals are created by the video card and amplified by the video board. The transistor is like a switch that turns the beam on or off (and provides the voltage required by the electron gun). If you want grey-scale, you will need to generate a range of voltages. You need a different configuration of transistor so the output is a voltage somewhere between zero and max.

Hmm what do the expert's think?

PS: does anyone still have the "activate all resolutions" shareware system expansion that lets you change the resolution on the fly for any resolution that is supported by the video card?

that is correct, i didn't touch a thing on the Mainboard or A/B…

we're nowhere nearer a grey-scale mod

yeah you are also correct on this one to… right now the greyscale videoboard hack is all hot air until someone

fires up their iron and makes it happen.

And that is why i am glad you are showing interest in this because, I KNOW you are a go get er.

It would be fantastic if you wanted to have a go at this!

I don't think this would have helped in this case, but I came across this bugger on eBay.

yes i bet that would help out in-fact, i have known about that item though. 200.00 way to steep!

the video cards are a few bucks and my electronics nippers are free… that super mac expandop, for a couple bucks could be used if one didn't have a mac con ethernet card.

and with the savings you could buy a floppy emu and just run the IDC out of the front through floppy slot… and there is still room for 2.5" sca to 50 pin hd solution… or SD2SCSI device.
