dance mat switches

hello

I would like to know what kind of switches are used in ‘dance mats’
used for playstation dancing games, im guessing they are pressure
switches.  Any ideas where i can find these switches in the UK.

thanks in advance

need datasheet for SC671DYB

Hello,
looking for SC671DYB datasheet. Chip is made by IMI (now Cypress?).
This is clock generator for Dell CPi laptop motherboard I am messing
with right now. Trying to see if I can get faster clocks out of it. At
least Intel chipset is capable of that.
Please give a link to the datasheet or send it to: nilsj at apollo.lv.
Thanx in advance.

MAX195

Hello Newsgroup,

my name is Gerry and I currently work with a group on our diploma project
(that’s the final exam period of my school type). In this project we use the
MAX195 16bit analogue digital converter.

We have now the following problem:
We made a printed circuit board and control the MAX195 directly with a PIC
microcontroller (PIC16F877). The MAX195 converts the analogue signal
correctly, but nearly every 3 seconds (it seems to be a periodic process)
the converted voltage "jumps"(e.g. from 1,12568 to 1,13568), but the
analogue signal (which has to be converted) does not.

We clock out the data serially (after the conversion) by setting the SCLK
pin high and low (controlled by the microcontroller).

If anyone of you has experiences with this ADC please help us,
we are trying to solve that problem for weeks without any results,

Gerry

Require logic array data for PALC16R4-30DMB

Troubleshooting board problem with PALC16R4. I have PAL program data
but no Truth Table. IF logic array data were available I could
possibly connect the dots and recover the logic.

Any help will be appreciated.

Eizo F77 flyback transformer WANTED

Hi,

The Eizo F77 seems to be no longer supported so no spares seem to be
available from Eizo in Europe at least…

Does anyone know where I can get a flyback transformer for one of these
animals? It seems a shame to trash an otherwise great monitor…

Thanks

Mike

Seeking a cheap simple wire-wrap wire stripper

Hi–

Around 1986 I bought at Radio Shack a little wire stripper for wire wrap
wire.

It was maybe about 3/4" square.  It was basically a flat blade somewhat
like a razor blade inside a flat metal frame.  It cost maybe a dollar or
was included with the $6 manual WW tool I bought.

Anybody know where I can find something like that nowadays?

Thanks.
