1. Random Access Memory RAM Acceleration of programs running in both main and auxiliary memory Totally transparent operation with all Apple software Other than obviously increased speed operation is also transparent to the user Can be installed in an Apple Il Il lle or Enhanced e Compatible with virtually all interface and expansion cards for the Apple Three speed settings 1 MHz 1 7 MHz and 3 6 MHz Can be controlled from hardware or software No preboot disk is needed Low power design for cool operation Works with all Apple software including AppleWorks SuperCalc 3a and Applied Engineering s RamDrive programs for DOS 3 3 ProDOS and Pascal Expandability Accelerated 16 Bit option available from Applied Engineering Getting Started TransWarp Before the TransWarp card is installed in the computer some of the switches on the TransWarp card may need to be changed to accommodate the timing needs of the other cards installed in your system TransWarp will work with all standard peripheral cards such as expanded memory cards printer and modem interfaces clock cards 80 column cards mouse cards and disk drive controllers Some of these cards though may not operate as expected at the higher TransWarp speeds By setting the switches on the TransWarp card you can tell the TransWarp s circuitry which cards in which slots require the 1 MHz clock rate This will allow TransWarp to slow down to the App2. language card bank switching technique described in the previous section On switch block 2 set the appropriate switch to the OPEN position for any slot with an interface card that requires the 1 MHz timing sign al A switnch in the CLOSED position selects full TransWarp mode for the corresponding expansion slot Switches on either bank corresponding to EMPTY slots should be switched to the CLOSED position If you re not sure if a card requires the 1 MHz rate try it at TransWarp speed and see if it works TransWarp Switch 8 on both blocks are used in combination to select the default TransWarp speed These switches should both be in the OPEN position for Full Warp speed If switch 8 of block 2 is CLOSED the setting of switch 8 of block 1 is ignored by the TransWarp circuitry Figure 1 shows the possible combinations and the corresponding TransWarp speeds Figure 1 TransWarp Switch Blocks BLOCK 1 BLOCK 2 Memory Card Periferal Card 1 slots 1 5 slots P Full TransWarp 3 6 MHz OPEN 0 _ _ OPEN Half TransWarp 1 7 MHz OPEN Normal Apple 1 MHz OPEN saci 5 CLOSED Normal Apple 1 MHz CLOSED 0 5 CLOSED Figure 2 Sample Switch Configuration for Apple e System BLOCK 1 BLOCK 2 here to OPEN here to CLOSE Press switch A Press switch System Configuration TransWarp Switch Settings Slot 1 Parrallel Printer Interface

5. TRANSWARP USER S MANUAL APPLIED ENGINEERING About This Manual TransWarp This manual tells you all about installing and using the Applied Engineering TransWarp accelerator card To get the most out of your new TransWarp please read this manual carefully Here s a summary of what is covered Introduction A brief overview of the TransWarp card and its features Getting Started What you need to know and do before installing the Trans Warp card in your system Installation How to configure and install the TransWarp card in your computer Using TransWarp How to activate and control the TransWarp card This manual was written under the assumption that you are at least familiar with the operation of your computer For more information on the basic operation and set up of your system please refer to the Apple Owner s Manual for your particular computer TransWarp Introduction The 6502 microprocessor or Central Processing Unit CPU on an Apple II or e computer executes its instructions at a rate of 1 MHz One megahertz or one million times a second TransWarp puts the Apple s microprocessor to sleep while doing some special tricks with its on board memory and uses its own high speed microprocessor chip to increase the processing speed to 3 6 MHz It s as simple as that Here s a list of some of the TransWarp s features 65002 microprocessor running at a 3 6 MHz clock rate 256K of ultra fast
6. TransWarp switch to slow down for that expansion card slot The instructions for setting these switches are in the next section Note TransWarp was designed to be very power efficient but like all accelerator cards it draws a fair amount of power and generates heat Applied Engineering recommends the use of a cooling fan such as the Kensington Microware System Saver especially when the TransWarp is installed in a lie with the newer style case These specially designed fans are available from many computer dealers TransWarp TransWarp Installation Procedure Step 1 Step 2 Step 3 Step 4 Don t ZAP your TransWarp Some components on the TransWarp card are especially static sensitive Even a small electro static discharge could damage one of TransWarp s integrated circuit chips A damaged chip might not fail right away but over time it could become worse possibly causing one of those nasty intermittent problems Be very careful to handle the TransWarp card ONLY by the edges Don t touch the gold edge connector or any of the components on the TransWarp card other than the switches Leave the TransWarp card in its anti static bag until instructed to remove it Leave your computer plugged in but switch the computer power switch to the OFF position Remove the top lid of the computer and set it aside Verify that the red power on indicator light inside the computer is OFF The indicator light is on the main

8. le s clock speed momentarily when those cards are accessed by the software This has a very small effect on the overall TransWarp speed since these interfaces are accessed for very short periods of the computer s time TransWarp mustbe specially configured to be compatible with memory expansion cards which install in the Apple s expansion slots zero through seven and use the 80000 to FFFF language card bank switching technique to expand the Apple s memory For details on the operation of your memory card refer to its instruction manual Newer expansion slot memory expansion cards do not use this technique The procedure for configuring the TransWarp card for expansion slot memory card compatibility is explained in the next section Due to the number and variety of expansion and interface cards available it is impassible to list which cards require the 1 MHz clock rate Without a great deal of technical information it is also impossible to determine which cards will or won t work at TransWarp speed Generally most floppy disk controllers serial printer and communications interfaces and clock cards do require the 1 MHz timing signal Parallel printer interfaces hard disk controllers 80 column cards and mouse cards usually will operate correctly at full TransWarp speed The simplest method of determining the timing signal requirement of a card is to try it at TransWarp speed If it doesn t work properly set the appropriate

10. tivate TransWarp is by powering up or cold booting the computer Occasionally it may be desirable to run some video demonstration programs games sound synthesis programs or other programsatnormal Apple speed or at a slower accelerated rate This can be accomplished through hardware commands software commands or a combination of both To disable the TransWarp completely immediately after power up press the ESCape key while the TRANSWARP logo is still displayed on the screen The system will continue to boot normally and run at the normal Apple speed of 1 MHz using the Apple s processor and memory IMPORTANT If your TransWarp card is installed in slot zero of an Apple Il disabling the TransWarp card will also disable the TransWarp s language card feature If you encounter this situation install your language card in slot zero and the TransWarp in another available slot Remember the initial soeed of the TransWarp is determined by the two number eight switches on the TransWarp card and is indicated to the user by the relative pitch of the speaker s beep at power up For example if switch 8 of block 1 is CLOSED and switch 8 of block 2 is OPENthe maximum TransWarp speed will be slowed to 1 7 MHz The beep of the speaker will be slightly lower pitched at this rate Software Control CP M Software TransWarp Programmers can also control TransWarp from within their programs by writing a specific va
