/CSn are two separate signals (/CS1 for controller/memory card port 1, /CS2 for
port 2). All other signals are exactly the same on all four connectors (with the
memory card slots lacking the /IRQ pin and shield).
/IRQ pin
Most or all controllers leave pin 8 unused, the pin can be used as lightpen
input (not sure if the CPU is automatically latching a timer somewhere?), if
there's no auto-latched timer, then the interrupt would be required to be
handled as soon as possible; ie. don't disable interrupts, and don't "halt" the
CPU for longer periods (as far as I understood, the GTE can halt the CPU when
trying to read results of incomplete operations; to avoid that, one could wait
by software, eg. inserting NOPs, before reading GTE results...?)
(Some (or maybe all?) existing psx lightguns are reportedly connected to the
Video output on the Multiout port for determining the current cathode ray
position though).

The plug on that cable does have additional sparings for pin 1,3,5 (though without any metal-contacts installed in there) (pin 3,5 would be used as supply for external RF modulators) (no idea what pin 1 could be used for though?).
RGB displays may (or may not) be able to extract /SYNC from the Composite signal, if that doesn't work, note that /SYNC (and separate /VSYNC, /HSYNC signals) are found on the GPU pinouts, moreover, the GPU outputs 24bit digital RGB.
Not sure if a VGA monitor can be connected? The SYNC signals are there (see GPU pinputs), but the vertical resolution is only 200/240 lines... standard VGA displays probably support only 400/480 lines (or higher resolutions for newer multisync SVGA displays) (as far as I know, the classic 200 lines VGA mode is actually outputting 400 lines, with each line repeated twice).
Parallel Port (PIO) (Expansion Port) (CN103)
This port exists only on older PSX boards (not on newer PSX boards, and not on
PSone boards).
The parallel port is used by various third-party unlicensed cheat cartridges and
VCD player addons, as well as by the PSIO optical drive emulator (see below).

Internal Power Supply (PSX)
The PSX contains an internal power supply, however, like the PSone, it's only
having a "Standby" button, which merely disconnects 3.5V and 7.9V from the
mainboard. The actual power supply remains powered, and wastes energy day and
night, thanks Sony!
External Power Supply (PSone)
Inner +7.5V DC 2.0A (inside diameter 0.8mm)
Outer GND (outside diameter 5.0mm)
Pinouts - SIO Pinouts
Serial Port
That port exists only on original Playstation (not on the PSone). The shape of
the Serial Port is identical to the 12pin Multiout (audio/video) port, but with
only 8pins.
1 SIO1 In RXD receive data (from remote TXD)
2 SIO2 - VCC +3.5VDC (supply, eg. for voltage conversion)

6 SIO6 Out DTR (to remote DSR) |_________________|
7 SIO7 - GND Ground (supply, eg. for voltage conversion)
8 SIO8 Out RTS request to send (to remote CTS)
Shield GND Ground (to/from remote GND)
PSone Serial Port
The PSone doesn't have an external serial connector, however, easy to use
soldering points for serial port signals are found as cluster of 5 soldering
points (below CPU pin52), and a single soldering point (below CPU pin100),
arranged like so (on PM-41 boards) (might be different on PM-41(2) boards):
CPU70.RTS
CPU71.CTS CPU74.TxD
CPU72.DTR CPU75.RxD CPU73.DSR
If you want to upgrade the PSone, remove that resistors, and then install the PSX-style serial circuit (as shown below), or, think of a more simplified circuit without (dis-)inverted signals.
PSX Serial Port Connection (PU-23 board) (missing on PM-41 board)
The PSX serial circuit basically consists of a few transistors, diodes, and
resistors. The relevant part is that most of the signals are inverted -
compared with RS232 signals, the CPU uses normal high/low levels (of course
with 0V and 3.5V levels, not -12V and +12V), and the signals at the serial port
socket are inverted. Ie. if you want to built a RS232 adaptor, you must either
externally undo the inversion, or, disconnect the transistors, and wire your
circuit directly to the CPU signals.

Note that there is no positive voltage protection (ie. +12V inputs would do no good, also strong -12V inputs might overheat the diodes/fuses, so if you want to use RS232 voltages, better use a circuit for voltage conversion).
Serial RS232 Adaptor
The PSX serial port uses 0V/3.5V logic, whilst RS232 uses -5V/+5V...-15V/+15V
logic. An example circuit for converting the logic levels would be:

|______| |______|
The four inverters are needed only for external adapters (which need to undo the transistor inversion on the PSX mainboard) (ie. the inverters are not needed when when connecting the circuit directly to the PSX CPU).
The second MAX232 chip is needed only if DTR/DSR "not ready" conditions are required (for an "always ready" condition: DSUB.4.DTR can be wired to -8.5V, which is available at Pin6 of the first MAX232 chip, and PSX.DSR can be wired to +3.5V).
With the above DSUB pin numbers, peripherals like mice or modems can be connected directly to the circuit. For connection to another computer, use a "null modem" cable (with crossed RXD/TXD, RTS/CTS, DTR/DSR wires).
The circuit works with both VCC=5V (default for MAX232) and with VCC=3.5V (resulting in slightly weaker signals, but still strong enough even for serial mice; which are mis-using the RS232 signals as power supply).

CPU Pinout Notes
- On (some?) retail consoles,
RAM.A11is wired to the RAM chips' A8 line, whileRAM.A8andRAM.A10are left unconnected. RAM./RAS1is only used on systems with 4 or 8 MB RAM./RC_NETis tied to 3.5V, while/CSHTST(test pin?) is wired to ground.SYSCK0(33 MHz),DSYSCK0(67 MHz) andSYSCK1(33 MHz) are clock outputs from the CPU to the rest of the system.TIMER0.CLKis fed from the GPU'sDOTCKoutput, whileTIMER1.CLKis fed from itsHBLANKoutput.CRYSTALPandCRYSTALNare meant to be connected to a crystal, however all known console models feedCRYSTALPwith the clock generated by an external oscillator and leaveCRYSTALNopen.SBUS./WR1(upper byte write strobe) is routed to the expansion port but otherwise left unused, as all system bus devices are either 8-bit (CD-ROM, BIOS ROM) or only support 16-bit writes (SPU).SBUS.A0-SBUS.A23are latched outputs and are not affected by RAM and GPU addressing.
Pinouts - GPU Pinouts (for old 160-pin GPU)
Old 160-pin GPU is used on PU-7 boards and EARLY-PU-8 boards.
IC203 - Sony CXD8514Q - Old 160pin GPU for use with Dual-ported VRAM
Unlike the later 208pin GPU's, the old 160pin GPU has less supply pins, and, it
doesn't have a 24bit RGB output (nor any other video output at all), instead,
it's used with a RGB D/A converter that reads the video data directly from the
Dual-ported VRAM chips (ie. from special RAM chips with two data busses, one
bus for GPU read/write access, and one for the RGB video output).

IC207 - SONY CXD2923AR - Digital VRAM to Analog RGB Converter (for old GPU)
This chip is used with the old 160pin GPU and two Dual-ported VRAM chips. The
2x16bit databus is capable of reading up to 32bits of VRAM data, and the chip
does then extract the 15bit or 24bit RGB values from that data (depending on
the GPU's current color depth).
The RGB outputs (pin 5,7,9) seem to be passed through transistors and
capacitors... not sure how the capacitors could output constant voltage
levels... unless the RGB signals are actually some kind of edge-triggering PWM
pulses rather than real analog levels(?)

GPU Pinout Notes
SGRAM./CS1is only used on arcade boards with 2 MB VRAM (two 1 MB chips).HVHLDhas a 4.7k pullup to 3.5V.TEST0-TEST3are tied to 3.5V.PCKSL0-PCKSL2(outputs possibly related to the current resolution/pixel clock?) are left unconnected.MCLKINandMCLKOUTare tied together and wired to the DAC's clock input.MCLKINcould possibly be an external clock input for genlocking purposes.- On earlier motherboards and on most arcade boards only
VCLK_PALorVCLK_NTSCis wired up, depending on the console's region. On later boards both are tied together and connected to a programmable clock generator, which is preprogrammed to generate the appropriate frequency. /VSYNCand/HSYNCare only connected to test points./CSYNC = (/VSYNC AND /HSYNC).BLANK = (VBLANK OR HBLANK).SGRAM.DQMLis wired to bothDQM0andDQM2on the SGRAM, whileSGRAM.DQMHis wired to bothDQM1andDQM3.DMASKoutputs the mask/"alpha" bit of the current pixel and is used by some arcade boards to composite the GPU's output on top of an external video source.ODE2indicates which field is currently being output in interlaced mode.

Pin 3..8 (analogue outputs) are passed via external 75 ohm resistors.
Pin 6,7 additionally via 220uF. Pin 8 additionally via smaller capacitor.
Pin 10 (YTRAP) wired via 2K7 to 5.0V.
Pin 1,44,46,48 (can) connect via capacitors to ground (only installed for 44).
The 4.4MHz clock is obtained via 2K2 from IC204.Pin6.
The /PAL pin can be reportedly GROUNDED to force PAL colors in NTSC mode, when
doing that, you may first want to disconnect the pin from the GPU.
Note: Rohm BH7240AKV has same pinout (XXX but with pin7/pin8 swapped?)
Beware
Measuring in the region near GPU Pin10 is the nocash number one source for
blowing up components on the mainboard. If you want to measure that signals
while power is on, better measure them at the CPU side.

HC05 - 32pin/64pin Versions
Sony's Digital Joypad and Mouse contain 32pin CPUs, which are probably also
HC05's:
Pinouts - Component List and Chipset Pin-Outs for Digital Joypad, SCPH-1080
Moreover, some old memory cards contain a 64pin Motorola SC419510FU (probably
also a HC05) with separate Atmel AT29LV010A (128Kx8 FLASH).

Pinouts - CLK Pinouts
The "should-be" CPU clock is 33.868800 Hz (ie. the 44100Hz CDROM/Audio clock,
multiplied by 300h). However, the different PSX/PSone boards are using
different oscillators, multipliers and dividers, which aren't exactly reaching
that "should-be" value. The PSone are using a single oscillator for producing
CPU/GPU clocks, and for producing the TV/color signal:
For PAL, Fsc=4.43361875MHz (5^6*283.75Hz+25Hz) --> 4*Fsc=17.734MHz
For NTSC, Fsc=3.579545MHz (4.5*455/572 MHz) --> 4*Fsc=14.318MHz
PSone/PAL - IC204 8pin - "CY2081, SL-509" or "2294A, 1913"
Clock Multiplier/Divider
1 53MHz ;17.734MHz*3 = 53.202 MHz (?)
2 GND
3 X1 17.734MHz
4 X2 17.734MHz
5 67MHz ;17.734MHz*3*2*7/11 = 67.711636 MHz (?)
6 4.4Mhz ;17.734MHz/4 = 4.4335MHz (?) ;via 2K2 to IC502.pin15
7 3.5V
8 3.5V
PSone/NTSC - IC204 8pin "CY2081 SL-500" (PSone, and PSX/PU-20 and up)
Unknown. Uses a 14.318MHz oscillator, so multiply/divide factors must be
somehow different.
3*3*7*5/2/11 = 14.3181818
3*3*7*7*100 = 44100
14.3181818 * 3*7*11*64 / (5*5*5*5*5) = 67.737600
14.3181818 * 2*2*13/11 ... or so?
PSX/PAL
PU-7 and PU-8 boards are using three separate oscillators:
X101: 67.737MHz (div2 = CPU Clock = 33.8685MHz) (div600h = 44.1kHz audio)
X201: 53.20MHz (GPU Clock) (div12 = PAL color clock)
X302: 4.000MHz (for CDROM SUB CPU)
PSX/NTSC
PU-7 and PU-8 boards are using three separate oscillators:
X101: 67.737MHz (div2 = CPU Clock = 33.8685MHz) (div600h = 44.1kHz audio)
X201: 53.69MHz (GPU Clock) (div15 = NTSC color clock)
X302: 4.000MHz (for CDROM SUB CPU)

boards, however, the text layer on the board says that it's an "LC86F8604A"
chip. So, the CXD8732AQ is most probably a standard LC86F8604A chip (more on
that below) with a Sony Memory Card BIOS ROM on it.
The "SONY CXD8732AQ" comes in a huge 64pin package, but it connects only to:
5 = /IRQ7 (via 22 ohm) 2 = /RESET (from U2)
6 = JOYCLK (via 220 ohm) 30,31 = CF1,CF2 (12 clock pulses per 2us)
7 = /JOYn (via 220 ohm) 14,16,25,32,38,39,61 = 3.5V (via 3.3 ohm)
12 = JOYCMD (via 220 ohm) 8,15,28,29 = GND
13 = JOYDAT (via 22 ohm) All other pins = Not connected
Caution: The "diagonal edge" at the upper-left of the CXD8732AQ chip is Pin 49 (not pin 1), following the pin numbers on the board (and the Sanyo datasheet pinouts), pin 1 is at the lower-left.
Sanyo LC86F8604A
8bit CPU with 132Kbyte EEPROM, 4Kbyte ROM, 256 bytes RAM, 2 timers, serial
port, and general purpose parallel ports. The 132K EEPROM is broken into 128K
plus 4K, the 4K might be internally used by the CPU, presumably containing the
BIOS (not too sure if it's really containing 4K EEPROM plus 4K ROM, or if it's
meant to be only either one).

PSX-XBOO Upload BIOS
The required BIOS is contained in no$psx (built-in in the no$psx.exe file), the
Utility menu contains a function for creating a standalone ROM-image (file
PSX-XBOO.ROM in no$psx folder; which can be then burned to FLASH or EPROM).

Note
Instead of the above internal mod, the nocash kernel clone can be also
installed on cheat devices, which do also include DB25 connectors for parallel
port uploads, too.
For DB25 parallel port uploads, do the following mods to the cheat device:
- Datel: use the FiveWire mod to get it parallel port compatible
- Xplorer: simply wire DB25./INIT to EXP./RESET (with diode, if needed)
Mods - PAL/NTSC Color Mods
The PSX hardware is more or less capable of generating both PAL and NTSC
signals. However, it's having the bad habbit to do this automatically depending
on the game's frame rate. And worse, it's doing it regardless of whether the
board is having matching oscillators installed (eg. a PAL board in 60Hz mode
will produce NTSC encoding with faulty NTSC color clock).
color encoding PAL NTSC
color clock 4.43361875MHz 3.579545MHz
frame rate 50Hz 60Hz
RGB Cables
RGB cables don't rely on composite PAL/NTSC color encoding, and thus don't need
any color mods (except, see the caution on GNDed pins for missing
53.20MHz/53.69MHz oscillators below).
Newer Consoles (PU-22, PU-23, PM-41, PM-41(2))
These consoles have 17.734MHz (PAL) or 14.318MHz (NTSC) oscillators with
constant dividers, so the color clock will be always constant, and one does
only need to change the color encoding:
/PAL (IC502.pin13) ---/cut/--- /PAL (GPU.pin157)
/PAL (IC502.pin13) ----------- GND (PAL) or VCC (NTSC)
That works for NTSC games on PAL consoles (and vice-versa). However, it won't work for NTSC consoles with PAL TV Sets (for that case it'd be easiest to install an extra oscillator, as done on older consoles).
Older Consoles (PU-7, PU-8, PU-16, PU-18, PU-20)
These consoles have 53.20MHz (PAL) or 53.69MHz (NTSC) oscillators and the GPU
does try to change the clock divider depending on the frame rate (thereby
producing a nonsense clock signal that's neither PAL nor NTSC). Best workaround
is to install an extra 4.43361875MHz (PAL) or 3.579545MHz (NTSC) oscillator
(with internal amplifier, ie. in 4pin package, which resembles DIP14, hence the
pin 1,7,8,14 numbering):
GPU ------------------/cut/--- CXA1645M.pin6 SCIN
GPU ------------------/cut/--- CXA1645M.pin7 /PAL
Osc.pin14 VCC ---------------- CXA1645M.pin12 VCC (5V)
Osc.pin7 GND ---------------- CXA1645M.pin1 GND
Osc.pin8 OUT ---------------- CXA1645M.pin6 SCIN
Osc.pin1 NC --
GND (PAL) or VCC (NTSC) ------ CXA1645M.pin7 /PAL
Alternately, instead of the above mods, one could also install the missing oscillator (and remove its 0 ohm resistor), so the board will have both 53.20MHz and 53.69MHz installed; that will produce perfect PAL and NTSC signals in 50Hz and 60Hz mode accordingly, but works only if the TV Set recognizes both PAL and NTSC signals.
Notes
External 4.433MHz/3.579MHz osciallors won't be synchronized with the GPU frame
rate (normally you don't want them to be synchronized, but there's some small
risk that they might get close to running in sync, which could result in static
or crawling color artifacts).
For the CXA1645 chip modded to a different console region, one should also
change one of the resistors (see datasheet), there's no noticable difference on
the TV picture though.
Region Checks
Some kernel versions contain regions checks (additionally to the SCEx check),
particulary for preventing NTSC games to run on PAL consoles, or non-japanese
games on japanese consoles. Some PAL modchips can bypass that check (by
patching the region byte in BIOS). Expansions ROMs or nocash kernel clone could
be also used to avoid such checks.
