Schematic ATARI IDE IF V2 & & Flash TOS x4

Postby olivierg » Fri Apr 13, 2018 12:13 pm

Hello all,

I try to merge all schematics of ATARI IDE IF V2 & Flash TOS x4 from http://atari.8bitchip.info/astams.php

My idea is create PCB with flash memory for reduce the wiring.
I delete the part 6 ROMs, not need if i place 2 x ROM on PCB (it seems logical to me)

But i see on ATARI ST IDE IF.pdf the wire
ATARI ST IDE IF .pdf
:
1) RW_(OUT) TO TP5 (From R/W CPU)
2) WE_(OUT) TO TP7 (R/W inverted by TLL)

But in TOS FLASH MAIN.pdf
TOS FLASH MAIN.pdf

1) The TP7 signal as name RW
2) The TP5 signal as name MISO Or BANK SEL. 1 and go to A17(30) FLASH


I have the impression that there is a signal name error, but I do not know that it is the right one?

Thank you for your help.
Olivier
