RE: VECTOR: Probably a stupid question...

I use the brown plug for 240VAC!  (I'm in the UK.)

 

I'm thinking that maybe it's only so high because there's nothing being
drawn from it at the moment (1N is part of the clock and R/W circuit so
possibly its not being used?)  We'll see!  :o)  Someone is posting me a
74S04N so after I've replaced it I'll take another reading and see what its
at.

 

Thanks

12v dose sound high cheak ur mains voltage is it set to 100v not 110v?? ac
in "thats the plug with wires going back into its self"

I don't think I can 'borrow' any of the other gates :o(  It's a bit busy
already at 1N!  Plus it's two of the outputs that are incorrect.  :o(

 

I thought I'd probably find an 'S' on my scrap Asteroids board, but that's
an LS version too (and a 7404 elsewhere).  I'm going to try a friend of mine
tomorrow to see if he has one, else I think I'm just going to see how an LS
goes.

 

On other stuff.  My 10.3v unregulated is running at over 12v!  I know it's
unregulated, but that seems a bit too high to me?  Is that normal?

 

Thank you :o)

A 74F04 is fast, a 74S04 is a schottkey, a 74LS04 is a low power schottkey .
a 7404 is just a plain old TTL. How many gates is the 74S04 driving?

Picked up a non-working Star Wars the other day, have already found a faulty
inverter at 1N but suspect there's more faulty parts to be found!

 

My question is this.  can I replace the 74S04N at 1N with a 74LS04 or a
7404N?  Normally I can find a matching part on my parts pile but I can't
find one of these anywhere!  I'm suspecting the answer is no as I'm assuming
the S to mean it's fast (?)

 

Any help very much appreciated.

 

Thank you.
