+-----------------------------------------------------------------------+ From: brian.hammack TITAN ACCELLERATOR IIe Documentation +-----------------------------------------------------------------------+ Notice:The following was culled from the actual docs (which I don't have) but contains all the information you will need to get going. Credits go to Titan for the original docs, Neil for transcribing from them, << mushroom >> for re-transcribing, and Dr. Tom for making them freely available on the Internet. It took | me a full year to find anyone online who had this info! +-----------------------------------------------------------------------+ A) The Titan Technologies Accellerator IIe card can be used in an Apple ][ or ][+ as well as the //e with the same results, just different placement. If you have a ][ or ][+, put the card in Slot 0; the card can go in any slot on a //e except the auxilary slot (0). This card contains a 16k "language" card, replacing the one you may have in your ][ or ][+. If you have a memory card in Slot 0, you may remove it completely or put it into a different slot. B) Setting the switches: The first seven switches correspond to time-sensitive devices found in the slots; the eighth should remain OFF. If you have a Modem or an interface for one, Digitizer, Disk Controller, or other cards which uses iterative timing calculations in a given slot, flip the corresponding switch to OFF. Memory boards, 80 column cards, and Printer cards are not time-sensitive, and the switches corresponding to their slots as well as those of unused slots should be left ON. C) Setting the jumpers: There are seven jumpers which correspond to the slots (top=1) you have memory devices in. There is no jumper for the auxilary slot or Slot 0, depending on your computer, so don't worry about that one. Remove the jumper for any regular slot you have any sort of memory enhancement board in. As stated before, the Titan Tech Accellerator IIe card goes in Slot 0 of the ][ and ][+ or any slot except for the auxilary (0) on a //e -- Slot 3 is recommended since few other cards will work in that slot. D) Touch the power supply before installing the card into the computer, push it gently into the appointed slot, and put the cover back on. You're set! Notes about the card and useage: -- The speed of the card is 3.5 MHz at first powerup, and you will see the difference when running DOS 3.3, ProDOS, Pascal, and (presumably) any other language that does not require special hardware to use. -- To change the operation of your card, write or POKE this: Address (hex) (decimal) | Value (h) (d) | Function: ------------------------------------------------------------------- C086 49286 05 5 High speed (3.5 MHz) 01 1 Regular speed (1 MHz) 0A 10 Disable card For example, from a Basic prompt you type POKE 49286,1 to go slow. -- If you have a clock on your system, it is best to slow or disable the card before resetting the clock. The NoSlotClock is especially sensitive to system speed when the time setting utility is accessed. -- It will take a cold boot (power down) to reset the card's speed setting if you can't change it otherwise. Settings carry through on warm boots, which can have some practical advantages such as if you wish to play a game off of a boot-only floppy and need to slow the computer down before booting the disk. -- If you have a Microsoft Z-80 card or another brand of CP/M card which uses DMA, you must use the preboot disk which came with the Accellerator IIe. Z-80 cards which don't use DMA don't need to preboot. See the manual for your CP/M card for further details. You will NOT experience a speed increase when running CP/M software because the Accellerator IIe's 6502 processor is being bypassed. -- Caviats: The Accellerator IIe will NOT work with a Corvus Omniniet or other DMA devices. It will also NOT access the second bank of memory on a Saturn 32k RAM Board because the Language card built into the Accellerator IIe replaces it. Some programs which use newly implemented op-codes will NOT work with the Accellerator IIe; these are relatively few if you are using the card in an enhanced //e. Geeky stuff: The Accellerator IIe uses a 3.5 MHz 6502 CMOS which bypasses Apple's 1 MHz processor. The clock comes from the 7M expansion bus signal; the frequency is halved for normal operation; syncronization of offboard cycles comes from cycle stretching. The card is static-sensitive like all computer components and should be handled with the usual care, such as keeping the card in an antistat bag when not plugged into a slot inside the computer. - end -
