Which Daystar Card is this?
Posted by: steve on 2018-01-04 16:02:35 Hello, I found your forum while trying to research a Daystar Card I have I believe it is a 68040 Daystar card in a PDS adaptor card but would like to confirm and get more info. It was pulled from a IIsi. I understand that some of these are more rare than others, so wonder what particular model I have. I have seen a few of these up on ebay. If a particular photo angle would be more helpful please let me know. I also have 4 4 MB SIMMs pulled from the same IIsi Finally along with a bunch of software installer disks I also have 2 Daystar floppy disks: 1) Front label- DAYSTAR FILES. Back: P.D. REL 2 Copyright 1983-1995 51-00576 2) Front label - QUAD CONTROL. Back: REL 9 Copyright 1991-94 51-00033 A I would also like to know if the cards are soldered to each other or can be easily separated. If so how? Thanks very much Steve
Posted by: rickrob on 2018-01-04 16:20:36 Looks like a 'Turbo 040' card with the IIsi adapter card. Been looking for one of those 040 cards for my IIci. The 040 card is plugged in to the Cache slot on the adapter. Can be pulled out of the slot.
Posted by: Unknown_K on 2018-01-04 17:16:35 It is a later revision Daystar Turbo 040 with built in cache. More then likely a IIsi adapter.
Posted by: olePigeon on 2018-01-05 08:12:10 What the other 2 said. It's one of (if not the) best '040 upgrade for the Macintosh. Daystar made adapters for it for nearly every 68k model.
Posted by: Trash80toHP_Mini on 2018-01-05 08:32:46 Lovin' your IIsi adapter. I'm wondering if it's the functional equivalent of the one joethezombie reverse engineered or slightly different. They made so many different iterations for the IIsi. I think this is the first I've seen with two sets of pads for the smaller GAL package. I'm soooo curious! Is there a copyright date on PCB a/o GAL sticker?
Posted by: steve on 2018-01-05 09:48:55 Thanx for the info. Not sure where to look for a copyright date on PCB a/o GAL sticker or how to recognize it. Can it be seen in the photos I had posted? Thx
Posted by: rickrob on 2018-01-05 17:38:06 The date code on some of the components like U1 and U2 is 1995, so it's 95' or later.
Posted by: Trash80toHP_Mini on 2018-01-05 18:44:33 That makes sense, we know the accelerator's of that vintage. But what I'm curious about is the year the adapter was made and if the GAL in the rear position is for 68040 and the front pads might be for 68030 variants of the accelerator. Copyright notice on the GAL's sticker would be the best indication. Year of manufacture would be second best, that's the only active component on the adapter. It's curious that there appears no date on the PCB?

It's curious that there appears no date on the PCB? Got it-- I thought you might have been just looking for a date of manufacture. On another note, I think there were some versions of the Turbo 040's with a small daughter card on the back. My guess is those were the earlier versions, or maybe the SE/30 version??
Posted by: steve on 2018-01-06 07:17:59 I've uploading some new images, after prying apart the PDS and 68040 cards. Perhaps they will be helpful. Thank you.
