A Daystar card in a Centris 660 av

A Daystar card in a Centris 660 av 68k 39 posts Aug 10, 2007 — Apr 8, 2008
Got a Centris 660 av with a Daystar card in it. It is connected to a Daystar

angle adapter. The Daystar card has a 040 chip on it. There is no id on the card other than Daystar on it. Is it a 040 card?

/ has a 040 chip on it. / Is it a 040 card?
Ummmmm .....

660av is a 68040 to start with.

And as far as a 68040 card being anything but a 040, think about it. :)

What does the card do?

Please put a pic of it up on flickr, it will be easier to identify if we can see it.

Huh. Whaddaya know. I guess it's a faster 040 upgrade. The code on the CPU die implies it's a 40MHz part.

Have you booted this machine and checked what System Profiler reports?

Looks like a 040 + cache and 2x DSP chips on a PDS card.

Will do that now. Just above the pds connector there is two 50 pin connectors. What are they for?

It says it is a Quadra 650 with a 68040. Tried without the card in and the hard drive would not boot. It was running 7.6.1. Took the card out and put it in a real Quadra 650 and it seemed a little faster. The hd would not boot without the card installed.

Can you post the text from the two matching large chips?

I found a mention of a "Daystar Image 040" here, but it says it's only for the Mac II, LC and SE.

that sounds like a DOS card. are the other chips pluggable?

Not a dos card. Similar though

The main board is an accelerator for the Quadras (with a faster 40mhz 68040 CPU). The slot on the card is probably designed to receive a DSP daughterboard.

The weird thing is the right-angle adapter : it seems to allow regular 68040-PDS cards to be puggled on the 660av Processor Direct Slot. Now, correct me if I'm wrong, but the 660av was not meant to have a true PDS since the logical space of the PDS was used fot the DSP (like the 840av, wich has no PDS slot at all)...

You are right in saying that the Centris 660av has no PDS slot like the Quadra 650 has. the q650 took the card with no adapter. Does the Centris 660 av have a full 68040 chip or the watered down one?

I'm guessing it's another one of DayStar's neat hardware tricks which allows the use of the same card in multiple machines...

It has a full '040, but only at 25MHz.

SCSI??

The FLEXlogic name sounds like it might be a FPGA or CLPD - possibly glue logic for the upgrade card. Can you tell where the traces from those two chips go?

Tried without the card in and the hard drive would not boot.
How far into the boot sequence did it get? Did you try with extensions off?

The fact that the '040 card itself works in a regular '040 PDS would bear this out. Do you have any other '040 PDS cards you could try in it?

Also, if you feel like selling this puppy - DIBS [:D] ]'> [:D] ]'>

Tried a google search - this thread is the second hit :-)

As I said in the post above, it sounds like one of DayStar's neat hardware tricks to allow the same card to be used in multiple machines... like how the Turbo040 works. That might also explain the FLEXlogic chips on the card. I doubt a normal '040-PDS card would work, and it would possibly bork the machine/card, so I wouldn't try it.

It says it is a Quadra 650 with a 68040. Tried without the card in and the hard drive would not boot. It was running 7.6.1. Took the card out and put it in a real Quadra 650 and it seemed a little faster. The hd would not boot without the card installed.
Can you check the system folder on your quadra 660av to see wich extensions / control panels seem to be related to the accelerator board? Also, do you have access to the DSP-related functions (speech recognition, geoport modem, video-in)?

I think the image 040 had similar functionality to the photoshop board expansion of the thunder IV.. not sure about compatibility or what software took advantage of it. Indeed.. I'm not sure how it works with (or against) the thunder IV board or what operating systems it was compatible with.

Oh and yes, I'm interested too should you wish to sell.

I do not know about geoprt modem but a modem was hooked up and connected to the net.

Try hooking up the video out to a TV

The only thing that was out of the ordinary was a folder with some .mov files. It also had a movie player program, not QT. Me thinks he was making

movies and that is why he had the card in.

edit:After finishing this post,I went to post the books that came the computer. There is one book of interest. Quicktime for the Web by Apple Computer. There is the old bill from Amazon .com to the owner of this computer. It gives his name and where he was. The Vancover Film School.

Going to see if he is still around.

Will do that now. Just above the pds connector there is two 50 pin connectors. What are they for?
There were daughtercards available for a range of Daystar processor upgrade cards (which is what you've got, a fast 68040 with probably 128k cache). The connectors were for these, which were, as has been said by another poster, for dsp daughterboards to speed up photoshop functions (using a narrow range of filters which were dsp-aware).

The connector had an acronym, which was, as I recall (I am away from home and references), QUIC, for Quadra Universal [interconnect?] Connector (or something to that effect).

Couldn't have been immensely popular, as the daughter boards are scarcer than hens' teeth. I've been on the lookout for years for one.

What year would these daugther cards been available? I have a ton of Mac magazines and could do some research.

Manufacture date was c. 1994.

I seem to recall also that the 660av pds and the 610 pds are one and the same. It is possible that what you have is an angle adapter originally meant for a Q610, which in that model (and not in the 660av) could also accommodate a ppc upgrade card. So look there too.

So it may be possible to plug in the Daystar 601 ppc 100mhz into the angle

adapter. It may be a tight squeeze.

1994. My mags go from 1985-93. Than 1998-99. I seen a ad for the cards in a 1993 issue.
