HARDWARE QUESTIONS


Q: On which Mac model can I install the Carrera040?

A: The Carrera040 is available for the IIci, IIsi, IIcx and IIx. The IIsi, IIcx and IIx require an additional adapter card, which is included.

Q: Are there any hardware incompatibilities?

A: We do have some reports of some Video Cards which are incompatibe. The symptom is that it doesn't boot. Please contact support@micromac.com for any updates

Q: Does the Carrera have an FPU?

A: The Carrera040 not only comes in different speeds, but also the choice of with or withour FPU. You can use Speedometer's Hardware Information window to see whether the FPU is built into the 68040.

Q: Are there other upgrades available for the Carrera040?

A: Yes. There is a 128KB L2 Cache card "Turbo-card" for the 66MHz and the 80MHz Carrera040.\Not for the 90MHz.

Q: Where can I find more technical information?

A: Use our on-line Mac Specs data base.

Q: How can I tell that the speed did increase?

A: If you cannot tell by the application you are using, you have to use Benchmark programs. We provide "Speedometer", a shareware program which tests (among others) the CPU and gives you a relative number based on a Mac Classic (vers.3) or based on a Q605 (vers.4).
You'd need to run this program before and after installing the upgrade.

Q: I currently have a FPU installed, can I still use this FPU once I installed the Accelerator?

A: No, once the Accelerator is active, it will disable the CPU and the FPU you have on your logic board.




SOFTWARE QUESTIONS


Q: Can I just install the XL or do I need a certain minimum System software?

A: The XL needs at least System 7.0 We recommend you install this System prior installing the upgrade. DO NOT USE "easy install", instead use "customize" for any Mac.
On top of it you need to turn 32bit addressing ON, you find it in the Memory Control Panel (the IIcx and IIx need MODE32 installed for it to appear)
Of course you also need the Carrera040 COntrol Panel in the Control Panel Folder AND the startup Carrera in the extension Folder for the XL to function correctly.

Q: The System starts up only until the Carrera Icon?

A: It is nor always the hardware. Here are some steps you can do:

• boot up with shift key down
• open the carrera040 control panel
• turn the switch to "slow"
• close the control panel
• select restart from the special menu
  

If this still does not boot your system completly, contact support@micromac.com
if it boots completly do these steps:

• after boot up you should see the "S" in the upper right corner of your screen
• open the carrera040 control panel
• turn the switch to "fast"
• now you should see the "F" in the upper right corner of your screen

The Carrera is now running in fast mode. No need to restart.

Q: Can I run OS8

A: Apple does not support OS8 on non 040 Mac's. And does not support System 7.6 on non 32-bit clean Macs any more (like IIcx or IIx). However there are some sofware solution. One is Pseus040.

Q: My software tells me that the CPU is running at half the speed as you soldit to me?

A: Your software is probably testing the Bus speed as supposed the CPU speed. See the FAQ main page for details.


Q: I'm convinced, yes I want to get this upgrade, what do I have to do?

A: To place the order, use this form (there is also a phone number on this form to call).
At the time you place the order you will be given a RMA number for you logic board, which you send back to us after the new logic board is completely working. This RMA number also appears on your invoice. There is also a deposit on the invoice for you old logic board, which we'll refund you upon receipt of your logic board.
