Pin #1 RocketChip Pin 1 Figure 1 - Apple II, II Plus Motherboard 5
Figure 2 - Apple IIe Motherboard STEP #4: Replacing the Apple II Expansion Boards and the cover. Install each of your expansion/peripheral boards back into the motherboard slot that it was removed from in Step #2. Replace the cover by inserting the front edge of the cover into the case and pushing it forward and then push down on the back edge of the cover to secure it STEP #5: System Check Turn on the system power.
3.2 Rocket.~hip Installation for the Apple IIC. MAKE SURE TEAT THE COMPUTER POWER IS "OFF” STEP #1: Removing the Apple IIc cover. Turn the computer over so that the bottom side is up and the keyboard side is down, resting on the work surface. Remove the six (6) screws that are shown in Figure 3. Note that two screws (#1 & #2) are larger than the others. Save the screws that you have removed. Figure 3 - Apple IIc Bottom Side Turn the computer over so that the keyboard side is up.
STEP #2: Folding up the keyboard. Grasp the Apple IIc keyboard assembly and gently lift the front edge (about 1/4”) and then pull it forward Out of the case (about 1/2”) to release the tabs on the back of the keyboard from the slots in the disk drive housing. Do not disconnect the flat cable that connects the keyboard to the computer motherboard. Gently fold the keyboard up and rest it on the computer as shown in Figure 4. STEP #3: Removing the 65C02 Microprocessor and Installing the Rocketchip.
Figure 4 - Apple IIc Motherboard Touch the disk drive housing. Remove the Rocketchip from the protective package. Look at Figure 4 and install the Rocketchip in the motherboard socket as shown. Please notice that RocketChip Pin *1 is marked and that all of the part number markings for devices on the motherboard and the Rocketchip are readable and oriented the same way.
4.0 R o c k e t C h i p Quick Reference - Operation Guide General: RocketChip powers up in a standard configuration mode with expansion slots *5 & *6 running at 1MHZ and slots #1, #2, #3, #4 & #7 running at 5MHz. This configuration accommodates most Apple II, II Plus, and IIe systems with a variety of peripheral expansion boards. The RocketChip auto identifies the Apple IIc, so that it operates at its maximum speed potential. The keyboard options offer you a choice of several feature selections.
4.2 Keyboard Selectable Options: The following modes of operation are activated whenever the CONTROL and RESET (CTL-RESET) keys are pressed at the same time and this key sequence is followed by: ESCape RETURN Space Bar Open-Apple CONTROL-Z CONTROL—D CONTROL-F RocketChip runs at 1MHz (Normal Apple speed) RocketChip returns to 5MBz or previously set RocketSpeed of 50KHz to 5MHz. RocketChip runs immediately without changing speed.

Rocketchip is an accelerator-on-a-chip for the Apple® II, II Plus, IIe and IIc. Requiring no slot, the 40-pin DIP package replaces the 6502 or 65C02 microprocessor, consumes less power than existing accelerator products, accesses expanded memory and lets your Apple II run up to five times faster. Compatibility RocketChip will run virtually all Apple II software, supports all peripheral hardware, works with any standard hard disk and supports all standard operating systems including ProDOS™ GEOS™ DOS 3.
