corresponding switch OFF. Set switch 8 OFF. Set all the other

switches ON.

STEP 10. Find the block of jumpers on the upper right of the Accelerator

IIe. Refer to figure 2. There are 7 jumper positions. The top

jumper goes with slot 1, the next with slot 2, etc. The bottom

jumper goes with slot 7. Now for each slot where you have any type

of memory board, remove the corresponding jumper(small plastic

gadget). If you have an Apple IIe, ignore the auxiliary slot. For

an AppleII or II plus, the Accelerator IIe will not recognize a

memory board in slot 0. Thus there is no jumper for slot 0. We

recommend that you put the Accelerator IIe in slot 0 of an Apple

II or II Plus.

STEP 11. Make sure the power is turned off for your Apple.Touch the power

supply again. Now plug the Accelerator IIe into the slot 0 on your

Apple II or II Plus, or into any available slot on your Apple IIe.

Slot 3 is a good choice for the Apple IIe, since the Accelerator

IIe wil work in slot 3 whereas most other cards won't.

STEP 12. Replace the cover to the Apple.

STEP 13. If you do NOT have a Z-80 card, skip this step. If you have a

Microsoft Z-80 Softcard or another Z-80 card which uses DMA, you

must use the preboot disk which came with your Accelerator IIe

before you run any Z-80 (CP/M) software. You do not need the

pre-boot if you have a Z-80 card which does not use DMA. Consult

your Z-80 card manual if in doubt.

To use the pre-boot, just boot the Accelerator IIe pre-boot

disk. It is already set for the "desireable" option, which is what

you need. Now remove the pre-boot disk, insert your regular CP/M

disk, and press the space bar. Run your programs as usual. Your

CP/M software will not speed up, since it is not using the

Accelerator's 6502. To get back to 6502 operation for DOS or

Pascal, you must reboot the system. Just turn off the power and

back on to get the accelerated 6502 operation.

STEP 14. All your software (except CP/M programs requiring a Z-80 card)

will now run approximately 3-1/2 times faster! If you want to slow

down (in order to play games, perhaps), you can use the pre-boot

disk provided with your Accelerator IIe board. Just boot this disk

before you run your game. Move the cursor to the "slow down"

position with the right arrow key. Now remove the pre-boot disk,

insert a regular DOS or Pascal disk, and press the space bar. Run

your program as usual.

Step 15. For more information, read Section II at your convenience

LIMITATIONS:

1. The Accelerator IIe will not speed upCP/M software running on a

Z-80 card. All other applications will run approx. 3-1/2 times

faster.

2. The Accellerator IIe is not compatable with the Corvus Omninet or

other DMA (direct memory access) devices.

3. The Accellerator IIe will not access the second bank of a Saturn

32k RAM Board, although the built in language card on the

Accellerator IIe effectively replaces this second bank.

4. A few programs are not compatible with the CMOS 6502 because they

treat newly implemented op-codes as no-ops.
