Applied Engineering About This Manual This 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.

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...

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 Apple’s clock speed momentarily when those cards are accessed by the software.

Discharge any static electricity that may be on your body or clothing by gently touching the metal power supply case. Step Carefully remove the TransWarp card from the anti-static bag. Put the bag flat on a table and set the TransWarp card on the bag. Step 4 Locate the two blocks of switches along the bottom edge of the TransWarp card.

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.

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.

1, or 3. A zero enables the maximum hardware default speed. A one will cause the TransWarp card to run at 1 MHz. Writing a three will disable the TransWarp card completely and pass processing control to the Apple’s processor until the TransWarp is again activated by cold-booting the system.
