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. The use of the configuration software allows you to make modifications for non-standard installations of expansion boards or to obtain maximum performance from your system

System Recommendations and Cautions

a)If your floppy disk drive controller card is not in either slot *5 or #6, you must use the Configuration Program to set your floppy disk controller card slot to 1MHz by using APPLE.SLOT7—1. Your floppy disk must operate at 1MHz or the diskette could be damaged. If you need to boot from the floppy disk that is not in slot #5 or *6, hold down the ESCape key during power up.

b)Do not use CACHE.SLOT7-l or CACHE.EXP.ROM7—1 to accelerate an Apple SCSI, AE ramfactor or any card that bank switches ROMs.

c)AUDIO.MUSIC and AUDIO.HIFI will slow down game play for any game that produces a lot of sound effects.

d)Any Apple II or II Plus without a paddle/joystick attached will cold boot every time that CTL—RESET is hit. To delete this function, use IIPLUS.NOBOOT or install a paddle/joystick and then CCNTROL—Z will provide a cold boot function for your Apple II or

IIPlus.

e)RocketChip must run at 1MHz when using some CP/M cards and cards that employ DMA. Use the Configuration Program, boot with ESCape, or CTL-RESET ESCape to set 1MHz

f)Several configuration programs can be combined to make a pre-boot HELLO or STARTUP file for your unique system configuration if needed

4.1 Power Up: RocketChip runs at the maximum speed of 5MHz with Apple

IIexpansion slots #5 & #6 running at 1MHz and slots #1, #2, #3, #4 & #7 running at 5MHz with all available Auxiliary memory being accelerated.

Holding down the ESCape key during Power Up forces the RocketChip to run at normal Apple speed of 1MHz.
