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 processi

TransWarp Before the TransWarp card is installed in the computer, some of the switches on Getting Started 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 s

TransWarp TransWarp Installation Procedure 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

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

TransWarp Step 5 Plug the TransWarp card in the expansion slot of your choice. If you are installing TransWarp in an Apple //e, slot 3 is recommended. If you have an Apple II or II+, slot 0 is the recommended slot. Since TransWarp also emulates the Apple II language card, which is usually installed in slot 0, the language card is not required when the TransWarp card is active. If you

TransWarp Software Control Programmers can also control TransWarp from within their programs by writing a specific value to a certain memory location. This location, expressed in hexadecimal notation, is $C074, and in decimal notation, 49268 (-16268 Integer BASIC complement). The valid values which can be written to this location are 0, 1, or 3. A zero enables the maximum hardware
