Hey!
Doing a repro of little samson (jap ver) on a HVC-TLROM-04 Board, and think I got all right exept the PRG.. I am using a 27C010 for CHR and 27C2001 for the PRG.
Where should I connect pin 24 on the 27C2001? And where should HOLE 24 go to? hole 2 and 24 are not connected together on this pcb.
Please see the attached document to see why I am confused by the absence of /OE and 2x /CE.
And even thou several guides online says that you can leave these ones floating, I know that I shouldnt.. However should:
27C010 pin1 (VPP) should be VCC or GND?
27C010 pin31 (/PGM) should be VCC or GND?
27C2001 pin1 (VPP) should be VCC or GND?
27C2001 pin31 (/P)should be VCC or GND?
This is how I have connected the rest as of now:
PRG (27C2001)
PIN 1 -> ?
PIN 2 -> HOLE 24
PIN 24 -> PIN 16
PIN 30 -> HOLE 1
PIN 31 -> ?
(Also I have HOLE 2 -> PIN 22 but didnt test it yet.. only did that because I read that 2 and 22 should be connected together on the pcb... both /CE??)
CHR (27C010)
PIN 1 -> ?
PIN 2 -> HOLE 24
PIN 22 -> HOLE 31
PIN 24 -> HOLE 2
PIN 31 -> ?
Thanks for your time!
