GS WorldView Titan Accelerator Information obtained from ftp://tarnover.dyndns.org/cabi/FAQs.and.INFO/Accelerators/A2.Titan.accel.dox.txt From: A2 History by Steven Weyhrich ref. Another speedup board was the Accelerator IIe by Titan Technologies (formerly Saturn Systems; they had to change their name because it was already in use by someone else). This board worked in a similar fashion to the SpeedDemon. Some users felt this product ran faster than the SpeedDemon, but it depended on the application being tested. Both boards were attached to the computer by plugging them into a slot other than slot 0 on the motherboard. TITAN ACCELERATOR IIe Author: Paul H Bauer Date: 1995/10/08 Section 1 STEP 1. DON'T TAKE THE ACCELERATOR IIE OUT OF THE PINK ANTI-STATIC BAG YET. STEP 2. Turn off the power to your Apple. STEP 3. Put a piece of aluminum foil on the table next to your Apple. STEP 4. Take the cover off the Apple. STEP 5. Make a list of the contents of each slot in a table like the one below: Slot 0 ____________________ Slot 4 ______________________ Slot 1 ____________________ Slot 5 ______________________ Slot 2 ____________________ Slot 6 ______________________ Slot 3 ____________________ Slot 7 ______________________ STEP 6. If you have an Apple II or II Plus,we reccomend that you put your Accelerator IIe in slot 0. If you have a memory board in slot 0 now move it to another slot or just take it out. The Accelerator IIe contains its own built-in language card with 16k of memory, so you don't really need another 16k memory board. STEP 7. On your slot table, mark the slot number(s) that contain DISK CONTROLLER CARD(S), MODEM INTERFACE, VIDEO DIGITIZER CARD, or other interfaces to time-sensitive devices. A time-sensitive device is one whose controlling software makes iterative timing calculations. This does not include memory boards, 80 column cards, or printer interfaces. STEP 8. Touch the Apple's power supply to discharge any static electricity on your fingers. Then remove the Accelerator IIe from its pink bag and put the board on the aluminum foil. Make sure each pin is touching the aluminum foil to prevent static buildup. STEP 9. Find the block of small switches on your Accelerator IIe board. Switches 1 to 7 correspond to slots 1 to 7. For each slot with a time sensitive device (refer to your slot table), set the corresponding switch OFF. Set switch 8 OFF. Set all the other switches ON. STEP 10. Find the block of jumpers on the upper right of the Accelerator IIe. Refer to figure 2. There are 7 jumper positions. The top umper goes with slot 1, the next with slot 2, etc. The bottom jumper goes with slot 7. Now for each slot where you have any type of memory board, remove the corresponding jumper(small plastic gadget). If you have an Apple IIe, ignore the auxiliary slot. For an AppleII or II plus, the Accelerator IIe will not recognize a memory board in slot 0. Thus there is no jumper for slot 0. We recommend that you put the Accelerator IIe in slot 0 of an Apple I or II Plus. STEP 11. Make sure the power is turned off for your Apple.Touch the power supply again. Now plug the Accelerator IIe into the slot 0 on your Apple II or II Plus, or into any available slot on your Apple IIe. Slot 3 is a good choice for the Apple IIe, since the Accelerator IIe wil work in slot 3 whereas most other cards won't. STEP 12. Replace the cover to the Apple. STEP 13. If you do NOT have a Z-80 card, skip this step. If you have a Microsoft Z-80 Softcard or another Z-80 card which uses DMA, you must use the preboot disk which came with your Accelerator IIe before you run any Z-80 (CP/M) software. You do not need the pre-boot if you have a Z-80 card which does not use DMA. Consult your Z-80 card manual if in doubt. To use the pre-boot, just boot the Accelerator IIe pre-boot disk. It is already set for the "desireable" option, which is what you need. Now remove the pre-boot disk, insert your regular CP/M disk, and press the space bar. Run your programs as usual. Your CP/M software will not speed up, since it is not using the Accelerator's 6502. To get back to 6502 operation for DOS or Pascal, you must reboot the system. Just turn off the power and back on to get the accelerated 6502 operation. STEP 14. All your software (except CP/M programs requiring a Z-80 card) will now run approximately 3-1/2 times faster! If you want to slow down (in order to play games, perhaps), you can use the pre-boot disk provided with your Accelerator IIe board. Just boot this disk before you run your game. Move the cursor to the "slow down" position with the right arrow key. Now remove the pre-boot disk, insert a regular DOS or Pascal disk, and press the space bar. Run your program as usual. Step 15. For more information, read Section II at your convenience. LIMITATIONS: 1. The Accelerator IIe will not speed upCP/M software running on a Z-80 card. All other applications will run approx. 3-1/2 times faster. 2. The Accellerator IIe is not compatable with the Corvus Omninet or other DMA (direct memory access) devices. 3. The Accellerator IIe will not access the second bank of a Saturn 32k RAM Board, although the built in language card on the Accellerator IIe effectively replaces this second bank. 4. A few programs are not compatible with the CMOS 6502 because they treat newly implemented op-codes as no-ops. SECTION 2 - Accellerator IIe INFORMATION PROCESSOR The Accellerator IIe is based on a CMOS 6502 microprocessor running at 3-1/2 MHZ. This replaces the Apple's 1 MHz 6502 processor for all computation. The Accellerator's clock is derived from the 7M signal on the expansion bus. The frequency is divided by 2 for normal operation of the Accelerator. Synchronization of off-board cycles is accomplished by cycle stretching. CMOS parts are particularly sensitive to static electricity, and for this reason the Accellerator IIe should be handled with some care. Ground yourself by touching the Apple's power supply before removing the Accellerator IIe from its anti-static bag. Place the board on a piece of aluminum foil or other conductor to set the switches and jumpers. Be sure every pin on the back of the board is touching the conductor during the operation. Once the board is plugged in, never touch it without first touching the power supply. Avoid excess handling of the Accellerator IIe. The board should always be kept either in its anti-static bag or in one of the Apple's slots. CONTROL PORT The Accelerator IIe operating mode may be controlled by execution of a machine language write cycle or BASIC poke according to Table 1: Table 1 ___________________________________________________________ Address Data Function ___________________________________________________________ C086 05 High speed (normal operating mode, set on power-up) C086 01 Low speed C086 0A Disable I think this should give enough information to write a simple basic program to set the speed of the card or disable it. ------------ Author: Mitchell Spector Date: 1998/01/20 In article Sean Fahey writes... >Does anyone have the documentation for the Titan Accelerator //e? I'd >like to know the correct settings for the switch blocks. According the (photocopied) manual that came with my Titan board, switches 1, 2, 3 and 8 are reserved for diagnostics and should always be set to the 'ON' position. Switches 4 through 7 correspond to slots, and should be set to 'OFF' _only_ if you have a timing sensitive card or device installed (e.g. disk controller, video digitizer, etc). Older/newer revisions of the card may have had switches 1 to 7 correspond to the internal slots, though I can't test it properly since my card seems to be defective (sadly I've had to remove it and let it go to waste in a box, like the defective TransWarp GS I own :/). One of these days I like to repair it, it runs faster than my stock Apple IIgs and Apple IIc Plus. :-) ------------ Author: Patrick Schaefer Date: 1998/01/21 Mitchell Spector wrote: > According the (photocopied) manual that came with my Titan board, > switches 1, 2, 3 and 8 are reserved for diagnostics and should always > be set to the 'ON' position.

This was for the old Accelerator II. The new Accelerator //e (with the two big chips in the middle) has eight switches and seven jumpers. Sw1..7 should be set to 'off' if there is a card in the corresponding slot which needs 1MHz timing (eg disk controller). Sw8 slows down the whole system to 1MHz, but the computer will still use Accelerator's ram and cpu. As far as I remember, the jumpers must be set (or removed?) if the card in the corresponding slot uses dma. ------------ Author: Brian Hammack Date: 1997/04/07 Mitchell spewed forth: SCC(| I picked up some odds and ends on the weekend (still going | through it) and one interesting item is a Titan Accelerator II I have two, I think they're pretty neat. SCC(| First off, how did this accelerator differ from the TransWarp | and ZipChip in terms of functionality and compatibility? I would | like to install it in my Apple IIe and use with recent software, | like ProTERM. There is a bank of eight switches and seven jumpers Simply put: The two blocks correspond to the slots in a //e. The first block is for time-dependant slots (drives, printer, etc.) -- flip these switches OFF if there's something time sensitive in it. The second is for any memory you have in (if you are using a ][/][+ the card goes in the aux slot 0, and goes in any other slot on a //e, so there is no jumper for slot 0) -- pull the jumper OFF for any slot with memory. SCC(| As for working with the card, when I plug it in most software | will refuse to run. An "Unable to load ProDOS" message appears if | I try and start most things up (removing the boards fixes this). I have no clue. The Titan card replaces having a 65C02 in some applications but not others (Angel likes it, Shrink It does not). | Also odd, if I press control-reset, I see garbage off the to side | of the screen, like this: The card does retain a charge; my experience says that one has to power down for 15-20 seconds before rebooting to not get garbage. As for a control-reset, I haven't done that much lately. :) SCC(| Is the board not properly configured or does it sound | defective? All the chips are socketed (minus the silver "Titan | Technologies" box in the corner) but I'm not sure which chips The only thing I know is that you have to slow the thing down -- speed is 3.5MHz -- to reset any system clock you have, and some programs don't really like it (this happened with some BBS program I was setting up). The POKE there is: 49286,x where x=5 for fast and x=1 for 1MHz, and x=10 to turn the thing off completely (a dangerous choice). The card does wonders for me in Publish It! 4, speeds up the pagination in AppleWorks, and doesn't do anything special in ProTerm except change the tone of the "connect" sounds. :) * 2qwk! 2.03 * "Cold meat, mutton pies/Tell me when your mother dies" -boy -- -- yet another annoying post by brian.hammack@rook.wa.com -- deal with it. ------------ From: Scott G. There was also a Titan III plus IIe board? This is a special card that, when plugged into an Apple III, disables all emulation blocking hardware and makes the III able to run IIe software. With a 65C02, it will even run enhanced IIe software, but it won't do mousetext.
