[ukvac] Taito F3 System and a Phoenix board (TECH)
Morning all

I've just purchased a Taito F3 Motherboard. First thing I needed to do was
turn the volume down because it was too high, so I searched around for a pot
but.... no luck, theres a variable resistor (VR1) but this doesn't seem to
do anything and turning the volume down to 0 in the test/set-up screen still
leaves the volume too high.
Am I being a dick??? Or is VR1 supposed to be a volume resistor??? If not,
what does it do?

I've also bought a Phoenix bootleg which is unlike any I've ever seen
before. Weird looking thing!! Its got a 22 way edge connector and the
board is marked P-81, theres some really weird looking components on it, 2
ENORMOUS capacitors and a tube looking thing with 'Mallory' written on it.
Theres also a metal circular thing in a 'cage' with RCA on it (sound I
assume) does anyone know anything about it, have pinouts, any advice on
anything??? Life, love, laundry??? My last few posts have all remained
unanswered, go on, if you can help, make a Pobster very happy.

Thanks,

Pobster

Hi,
you want to be very careful when turning the pot on the F3 mother as it is
not a volume pot, turning this usually results in destroying the F3 mother.
The pot controls some voltage related to the sound and has to remain it the
locked position.
The volume adjustment is in the test menu.
Use the test sw located on the board.

Thats interesting!!! A 'self-destruct' pot!!
But what exactly is the locked position as mine appears to be freely
rotatable??

Hi

On most of the F3 boards I've seen (cartridge based and dedicated) there has
been a label stuck over a pot on the board that says 'Do not adjust this
pot'. Not sure if it means VR1 without checking one of my boards but I would
guess that if it's not the volume pot then it does. Not exactly sure what
adjusting this pot will do but if I remember correctly the label makes it
clear that it's important you don't adjust it.

Doesn't appear to be very sticky anymore!! Nevermind! Thanks all for your
help!!

thats an interesting, but down to the point name for it.
I will see that I attach a sticker with that name to my F3 mother )

do the phoenix pinouts on spies match up to your board? ad does the board
work ?

Paul, don't touch the VR1, it regulates the voltage (+5 I think). The F3
board I have had a label attached to this effect. The F3 system uses
software to control things like volume, screen orientation, coins per game,
etc.

Well, this one is a 22 way and the pinouts on spies are for an 18 way. I
can work out this much:

On Both:

The first two are ground, the next two are probably +5 and +12 then Speaker.
15 on parts is ground again, and both sides 21 and 22 are ground.
Thats all I know how to work out for myself :O)

Paul,

The volume on the F3 motherboard is software
controlled. All you need to do is press the small
black round 'test' button which is at the front right
of the board. This will bring up the software menu.

Cheers
