niceification. Bet they wont be the same price.

I let him know the good news, as well. Sure, he'll raise the price a bit, heck I've only been trying to get someone to get it to work in the SE/30 for him since February, 2012 and he's been selling them for next to peanuts the whole time.
He has some left and lots of the SuperMac PDS adapters. He's been good to the entire RetroMac community since long before there ever really was something to call that! :approve:

Thats awesome. Its people like that, who has a surplus of stuff to sell cheaply, Allows this to happen in the first place.

how long was it going to take for someone to get out the loppers and lop of a hunk of the card, if i wouldn't have?

Dunno, uni, but you did do it and it worked out great! 😉
Is there room for a second RCPII/IIsi to be plugged into the first? Looks to me like you wouldn't need the loppers if the card were just one PDS Displacement Unit farther forward.
Thats awesome. Its people like that, who has a surplus of stuff to sell cheaply, Allows this to happen in the first place. Exactly! He even mentioned that he felt like he's been a part of the achievement. Heck, he's the one who suggested the very notion of the SE/30 compatibility of this card. I'd say he was the founding member of the project team, not a mere part of it.
Props to macmetex! :approve:

he ought to try and sell the cards here instead of ebay, he would save the listing and value fees.

ok so i tried this IIsi radius card in the Iici and the CACHE PDS SLOT must be electrically incompatible SE/30 - IIsi PDS …
the IIsi psu boots up the main board w/o the video card plugged in though..

Yea, the IIci cache card connector is entirely different pinout, Just like the LC to SE/30. Needs a cross-pin converter PCB. But as far as that goes, all the signals for the 030PDS is there. 🙂
There are a few differences though, Such as the output enable/select lines for the cache card in the correct address space.
P.S. Designing cards and drivers for the macintosh family, Is on the googlez if you look for it. I wont link it as per the rules.

The IIci Cache Slot is a freakin' mess, not a PDS slot per se. DayStar made at least a baker's dozen REAL PDS Slot to flakola IIci Cache Slot Converters.
The one we need to reverse engineer is logic on the DayStar SE/30 adapter. That will be almost exactly the same logic needed for a IIsi adapter. I've got a lot of respect for the Japanese Gent who makes that tall adapter, but anything like that needs a second a/o third PDS Pass Thru Connector before I'd call it ready for prime time. Right now it has exactly ONE pass thru and a converted SE/30_PDS->IIci_Cache Slot available, not nearly good enough as compared to what can be achieved given the Gamba Diagrams. [}🙂] ]'>

It strikes me you shouldn't need any electronics to make a pds expander for the se30. (Emf type filtering aside).
A simple pcb with one male right angle and two female straight din's appropriately spaced should let you put two non-passthru type cards in where the hard drive lives. You repo the hdd on it's side and presto...
Would likely only work for non-accelerator cards but hey.

I've also noticed things seem to slow up a bit when driving two video cards. (However I've got that crazy address decode prob and have 4 monitors showing)
However, if you pull out the onboard declrom, then make the rcpii screen primary, the thing is quite snappy.
Now considering you don't use onboard video at all, replacing the crystal witha 40mhz jobbie should be possible.
the grayscale conversion would be the super bonus. An affordable, 20mhz, grayscale se30 with network card anyone?

ok so i tried this IIsi radius card in the Iici Why would you do that? Are you determined to break things?
The IIci Cache Slot is / not a PDS slot per se. Why do you keep saying that? Every PDS implementation has had a different pinout. That doesn't make it "not a PDS", when:
all the signals for the 030PDS is there Heck, it's more of a P.D.S. than any of the bridged "LC PDS compatible" slots in the post-030 Performas, which aren't Processor Direct Slots.

Because it's not, per se. A Cache Slot is more and less than a PDS slot at the same time.
A Cache Slot may have most of the features of a PDS, even more. These slots do have all of the same signals and may be a whole lot better than a PDS Slot in the same machine for some uses.
It was Apple who made this distinction, the first PDS was in the SE. Cache slots were introduced in the IIci and are for cache, without documentation for, or the requisite access to, utility outside the box.
By contrast, a PDS slot was well documented by Apple and intended for real world expansion by second source card manufacturers, even in the cases where it was intentionally hamstrung to limit Low End Macs from competing with the high end, as techknight pointed out..

I didn't come up with the idea on my own 🙂
I had my hand on the power cord, pull it real quick if the power button did nothing.

Can someone summarize where you guys are on this thread? Will this get an SE/30 internl gray scale graphics and the ability to put in a cheap ethernet card or am I mixing up a few threads?
