Daystar Upgrade Cards May Damage Your Computer Unless Installed Properly

 

 

 

WARNING! WARNING! DANGER, WILL ROBINSON! WARNING!

WARNING!

*ahem*

Do not plug ANY DayStar, Sonnet, MicroMac or other CPU upgrade designed for the IIci/IIvi/IIvx/P600 directly into a IIsi or SE/30 PDS. It WILL fry the upgrade and sometimes the Mac's logicboard. When you get the adaptor, plug the upgrade into the slot marked FOR CACHE CARD ONLY or similar. The other slot is a "pass through" so you can install a IIsi network or video card along with the upgrade.

Daystar made two other IIsi adaptors which are rather rare. One just converted the IIsi PDS into a IIci cache slot. The other was similar but plugged onto the PDS passthrough slot on a card already installed in a IIsi. The 030 PowerCache manual I have (if I still do) says there was only one card, a video card, that required the short adaptor. All others could plug into the passthrough slot on the dual slot adaptor. For the SE/30 there was only one adaptor type made and unless the Turbo 040 is exactly the same size or smaller than the 030 PowerCache, it won't fit.

The Mac II/IIx/IIcx had special adaptors to give them a IIci type of slot that the upgrades plugged into. So did the LC series. Prior to the IIci, DayStar made seperate upgrades for the Mac II/IIx/IIcx. These are very hard to find and have no advantages over the later IIci upgrade plus adaptor.

Due to some IIcx models having a soldered CPU, the CPU puller was not shipped with the upgrade. (After some people who didn't read the instructions closely trashed their logicboards!) IIRC, DayStar would remove the CPU, solder in a socket then install the upgrade or adaptor for free on a IIcx if you sent in your logicboard. You also got the old CPU back.

Hi,

I am in hot pursuit of the adapter that'll let me use the Turbo040 in my IIsi. But I have a couple questions first; I want to make sure I get the right adapter, and don't do permanent damage to my Mac.

It looks like the Turbo040 can plug right into the IIsi's PDS slot. If this is true, then I would assume the adapter is onl for height purposes. But...I know the Turbo040 works in the IIci as well, and I was under the impression (before I even bought the thing) that it plugs into the IIci's cache slot. -Which isn't the same as PDS... right?

These may sound like nit-picky questions, but I want to be totally sure of the situation, so I don't fry my IIsi's motherboard or something.

Thanks!
