This is the v1.4 ROM for AE's TransWarp accelerator card. If you don't have the latest version on your card then you'll want this ROM!
Just remove your old ROM and install the new one. It's that simple!
The ROM file is also available >HERE< for free if you wish to burn your own.
Tip: In an Apple II Plus, the TransWarp will emulate the 16k Language Card.
Pressing the <Esc> key a few times during the first two seconds on turning on the Computer will disable TransWarp completely until the next power Off/On cycle. A better way is to boot with the TransWarp enabled then write an '01' to location $C074. This will slow the TransWarp down to 1 MHz without disabling it completely. Writing an '00' to location $C074 will restore the TransWarp to it's 'fast' speed. If you write an '03' to location $C074, TransWarp will be shut down completely; the Motherboard Processor will take over when you hit CTRL-RESET. In order to turn the TransWarp back on, you have to turn the Computer off and back on again with the power switch. To write to location $C074 in BASIC type 'POKE -16268,x' or 'POKE 49268,x'. 'x' is a 0, 1 or 3.
The self-test is initiated by pressing the "0" or "9" keys a few times during the first two seconds on turning on the Computer. The test checks for the type of Processor installed (65C02 or 65802), measures the speed, tests bank switching, and tests RAM. If the TransWarp is installed in a //e, you can hold down the Open-Apple key to keep it looping through the speed test. The TransWarp measures its own speed by counting how many cycles it takes for the Vertical Blanking Signal to pass by. This signal is not available on the II or II Plus, so no speed tests are performed on those machines.
Bank #1 (left side): SW 1-7 - Switch number corresponds to Slot number. Change to OPEN if there is a memory card that uses the "Language Card bank switching technique". Normally all switches are CLOSED. Switch 8 is Speed setting and is listed below.
Bank #2 (right side): SW 1-7 - Switch number corresponds to Slot number. Change to OPEN if the plug in card must be accessed at 1 MHz. Normally all switches are CLOSED. It's recommended that Floppy Diskette Controllers be set to OPEN. Switch 8 is Speed setting and is listed below.
Switch 8 on both Banks: Sets the power up speed of the TransWarp
3.6 MHz OPEN OPEN <<Normal>>
1.7 MHz CLOSED OPEN
1 MHz OPEN CLOSED
1 MHz CLOSED CLOSED
