| Super rare Macintosh II Daystar PDS adapter |
Posted by: olePigeon on 2016-09-30 09:20:13 I came across a super rare Daystar PDS adapter for the Macintosh II. This sucker converts an 030 + FPU into a PDS slot.
If I ever come across a boxed Macintosh IIx, this would be the only machine that'd replace my IIci as my regular workhorse.
I've never seen one of these adapters before. Since I already have the expensive part (the Turbo 040), I figured I might as well get the adapter. You never know. 🙂
Still on the lookout for a Daystar Turbo 040 box. I'd like to get the box. I have the card, manuals, disks, etc., but no box. 🙁

Posted by: Elfen on 2016-09-30 09:58:58 Congrats. It is a hard thing to find. I would not mind having such an adapter but I do not have the machine to put it in. As Is, my Mac IIci is also my workhorse for it too has the 040 DayStar in it as well. Between that and my IIfx... well I'm still trying to decide which machine is the stronger of the two.
If I'm right, it can also work on the SE\30 if the CPU is on a socket.

Posted by: joethezombie on 2016-09-30 10:03:55 Now wait, what? If I'm reading that right, this plugs into the sockets of the 030 and the FPU on the logic board and gives you a PDS slot? Wha? Suppose you could upload a picture of that thing?

Posted by: joethezombie on 2016-09-30 10:23:16 Wow, that is a find! I didn't know such things existed! Now that is cool.

Posted by: Unknown_K on 2016-09-30 10:45:18 They made different ones for the Mac II and Mac IIx (different placement of the CPU and FPU). I have one for the II.

Posted by: olePigeon on 2016-09-30 10:51:38 Really? Awe, crap. Got the wrong one. 🙁 This is for the II.
|
Posted by: Unknown_K on 2016-09-30 10:53:46 The II is a slow 68020 so it would need a speed boost the most. Oddly enough I have 2 of the rarer IIx machines but still have not snagged a plain old II.
There is also a LC version which I have that plugs into the PDS port.

Posted by: olePigeon on 2016-09-30 11:07:10 Looks like the CPU positioning is flipped between the II and IIx, so the adapter would be facing the wrong way. 🙁

Posted by: Anonymous Freak on 2016-09-30 12:22:50 Huh. So you'd *HAVE* to use a PDS accelerator card, since there's no place to put the CPU+FPU back in! I guess since most PDS cards *ARE* accelerator cards, it makes sense, it just looks odd. You'd think a pure CPU upgrade would have been more popular than needing a separate "PDS adapter" and CPU upgrade...
|
Posted by: olePigeon on 2016-09-30 13:34:41 Daystar went the route of a single CPU upgrade and 10 different adapters.

Posted by: unity on 2016-09-30 18:49:17 I have one in my II also. I think I put in an 030 from Daystar. Cool thing is the ability to swap card as they are found with such an adapter. Meaning the accelerator itself is specific to the II. The II card will not work on all IIs since the first run does not have a fully-pined MMU socket. It was pin-specific to the chip used. Making PMU upgrades impossible on those boards. A silent recall replaced many of them.

Posted by: ArmorAlley on 2016-10-01 11:43:09 The Mac II starts off with System 4 and this card (along with the Turbo040) allows the Mac II to run a 68040 chip at 40MHz.
Not at all bad for System 4, when a 16MHz 68020 was considered fast (as, no doubt it was, back in 1987).
Has anyone tried this?
Is it actually possible to run System 4 on a 40MHz 68040?

Posted by: Unknown_K on 2016-10-01 12:53:41 I hope to find out someday.

Posted by: NJRoadfan on 2016-10-01 15:30:48 System 4 should run, its not like the 68040 broke much more than the 68020 did with regards to software. In related fun, I know that System 7.5.5 runs like greased lightning on a 450Mhz G4 with 256MB of RAM (upgraded PM8600) 😛

Posted by: Tam 400 on 2016-10-01 21:57:31 Just did a big clean out,found my Daystar,it's 030 not the 40.i don't have a Mac to put it in know.ijust kept most of the real rare stuff.

Posted by: CC_333 on 2016-10-02 16:53:59 A 68040 can still be used with a 68882 FPU, though, can't it?
