1.0: Original design 1.1: Minor modifications after Design Review 1.2: Added External 8042 Style Keyboard Controller (SH24) Removed Support M1487 Internal (SH15) Removed Keyboard Interface From Clock Page (SH17) Changed design name Am486PCI C.D.P. 1.3: Added Extra Bypass Capacitors (SH5 SH14 SH15 SH17) Swapped Around Some Signals Within Resistor Networks (SH6 SH20) Renamed MCLK1 M_CLK1 (SH24) Added 0-ohm resistor make pullup work (SH17) Added NetLister (SH3) Fixed Error 3.3V Regulator Circuit (SH12) 1.4: Rearranged Clock Nets Facilitate Routing (SH17) Changed Some Components Standard Values (50ohm 49.9ohm, 40pF 39pF, SH19) SH20: Removed unneeded 0-ohm resistors from Super chip Fixed wiring error crystal Added 'ABT125 buffer drive serial port LEDs SH22: MACH device outputs changed Flash support SH23: Changed Flash 1MByte (512Kx16) SH24: Removed unneeded logic from interface Added inverter generate proper chip Fixed wiring error crystal Grounded U22-pin Removed unused gate SH17 SH25: Switched mouse connector verticle type Changed 'F06 symbol show
(continued): SH17: Added jumpers allow mulitple BIOS images single Flash device Removed diode from VBAT generation circuit Added generation circuit spare 'F14 gates Added jumper external RESET# pushbutton SH18: Fixed wiring error crystal Removed MCLK1 (16MHz) rewired MCLK2 drive 33MHz clock nets Removed CLKCNTL signal from DOZE#
2.0: Changed resistor packs 10-pin (SH2, SH3, SH11, SH15, SH16, SH17, SH19, SH20 SH21) Changed 330ohm Resistor Pack 8-pin (SH19) SH3: Added diagram correct Power Connector Footprint Broke Logic Analyzer Headers into pages Added gnerate also generate Logic Analyzer Qualify signal Buffered BE[0.3], RDY#, BRDY#, ADS# through
SH9: Added better explanation Flash memory operation SH11: Added configuration information slots Removed circuit generate PERR# cause M1487 assert Am486 microprocessor SH13: Added serial EEPROM user parameters mux. circuit daisy chain device. '972 E/net device loads configuration from SEEPROM. CLKCNTL signal from M1487 used select SEEPROM. SH14: Swapped R107 R109; R109 49.9ohm, Fixed wiring error crystal SH15: Added more 0.1uF bypass capacitors chips ('F14, 'ABT125, 22V10, 'F08, 'C66) SH16: Fixed wiring error crystal Fixed wiring error generation low-active reset signal RSTDRV# Removed unused inverter (used SH24) Changed 1487NMI circuit Changed populated component
2.1: Updated revision level prototype warning sheets SH17: Modified jumpers allow mulitple BIOS images single Flash device support 256K 512K BIOS non-PC applications SH22: Added XBUSCSJ signal Mach device does respond when Am486 fetches reset vector FFFF FFF0 SH14 &20: Connected pins LEDs greater purchasing/manufacturing flexibility 2.1A: SH1: Rev. cover sheet text; design changes made! SH7: Changed Cache SRAM Speed 10ns

Using Logic Analyzer Headers: Clock analyzer clock signal (POD1) Qualify clock using LA_QUAL signal (POD2) This qualification signal asserted when ADS#, RDY# BRDY# asserted Am486 Microprocessor bus. Thus cycles where valid address data information transferred filtered when needed Signals arranged Headers work with Disassembler 16500 analyzer
