I recently picked up an odd card for the C-64 which appears to be an accelerator. I need help identifying the card and getting documentation. This is NOT a SuperCPU! The board is blue colored and bears a single identifying mark "4 Mhz". It contains the following components: 65816 processor W65C816P-5 EPROM GI 27C256-15 a DIP-block with 8 toggle switches a single red LED 1 250K Ohm variable resistor 1 1K Ohm variable resistor 1 3 pin connector 1 2 pin connector 1 pushbutton momentary-contact switch connected to (RESET) The 'solder' side of the board contains a one component, a VARTA SafeTronic 2.4v 100mA black-box. I think this is either a real-time clock or possibly a battery unit for saving configuration settings. With the card plugged in, the computer powers up with blue border and blue screen and the message "TURBO-PROCESS 38911 BASIC BYTES FREE" The card contains its own KERNAL which defeats the Commodore-RUN/STOP shortcut for LOAD":*",8 on my SX-64. I'm afraid to mess with the variable resistors since tuning a resistor to zero Ohms may damage other componenets if they depend on it for a load. I have been experimenting with the dip switches and here's what I've found: Switch #1 - Enable/Disable, seems to totally kill the card when set to zero although the LED remains lit. Switch #2 - No apparent effect. Switch #3 - No effect. Switch #4 - When enabled the computer resets to a flashing border, but no BASIC prompt or screen display of any kind. Switch #6 - No effect. Switches #7 and #8 - Enabling either of these switches prevents BASIC from starting on reset. No menu or other screen display. And Switch #5 (OH YEAH!) - With #5 enabled the computer powers up with blue border, black background and yellow cursor. The sign-on message at the top of the screen is green and reads: "**COMMODORE 64 & TURBOPROCESS**" "38911 BASIC BYTES FREE SYSTEM 3 (UP)" In this mode there is a "@" DOS wedge present. LOADing a basic program yeilds the response: "SEARCHING" "LOADING TO AREA: 0801-0869" Some programs work with the card, others not, but I don't notice any acceleration. Can anyone help me identify this card and learn more about it, please? ===== Get a FREE 6Mb webmail box from go6502! - http://www.geocities.com/profdredd As low as 2.99% Intro APR from NextCard! - http://www.nextcard.com/index6.html?ref=aff0074521 PayPal is the FAST FREE and SECURE way to send money! - https://secure.paypal.x.com/refer/pal=profdredd%40yahoo.com __________________________________________________ Do You Yahoo!?
