The barcode from which the label ID is extracted is indeed the one on the back: http://furrtek.free.fr/noclass/esl/eslbarcode.png Does the ESL Blaster's red LED turn on ?
This signal emanates from the damaged zone on the die. Proceeding by elimination, it must be the output of the NAND gate A57 (page 13). The only possible inputs to...
Gates A104 and A57 updated with the only solution that makes sense. Pins P (Z80 data) are outputs when /PCS and /PRD are low. Pins AD (MCU data) are outputs...
The values mentioned in that comment were meant to reflect the settings in the registers (bits [3:2]), not the DTACK_SELx signals. If I'm not mistaken, those end up inverted after...
Confirming that the output level for both pins BR and BGACK is fixed low. /PIN_BR_EN and /PIN_BGAC_EN go straight to the IO blocks, they're used to enable the open-collector output...
Hi, yes it would be entirely possible if a schematic can be extracted. Careful analysis or simulation can then provide the values.
I believe that the M68K can't read anything from the 315-5195, it can only write to registers at startup. The direction signal for the M68K data pins seems to only...
On the two Sega schematics I have, the 315-5242 module's pinout matches the schematic. Maybe they didn't follow the same order for the output channels on some boards ? It...
They're the schematics for After Burner and Galaxy Force.
The Unibios reads bits 3 and 4 of REG_STATUS_A instead of bit 7 of REG_STATUS_B to determine the system type. Code was added in 8c46a32 to simulate the difference between...
