RE: Vortex schematics and old holtek chips

["plain jane" <info@plainjanemusic.com>]

I live in the states(Chicago,IL) and have access to servers to post 
the Vortex service manual. If Kim was willing I would scan in the
service manual and FTP the results. I work in web development for a
museum here in Chicago, IL so I have access to the necessary equipment.
Just letting everyone know that I'm up for the task if Kim is
interested.

Thanks,
Kevin McPeak

Subject: Vortex schematics and old holtek chips



HI Folks,
                Good to be back on this list after a long absence (what
*was* I
thinking! ).
I own a vortex and a while back I tried fitting in 256k DRAMS and made
some
good guesses at what to put in U10... Good news is my vortex is still
working,
bad news... no increased delay time :-( Maybe I guessed wrong on U10,
maybe
I need to go find me a DSP hacker. Anyway I was going through the list
archives
and came across the info that Kim has the vortex service manual and has
twice
tried
to get it scanned to no avail... any more news on that front?
I'd happily volunteer but living in the UK probably complicates things
:-) I do
have broadband however so maybe we could do it this way:
1) I paypal Kim some dosh to cover postage of a copy of the manual.
2) Manual arrives, I scan it and clean things up a bit.
3) I ftp the resulting files to some suitably receptive box.. or make
them
available
    on my server for Kim to download and post on the delight site for
all to
share.

Sound good?

On another line, does anyone know of a supplier of the (sadly obsolete)
holtek
HT8955A chip? radioshack used to sell it, it's a digital delay that
really just
needs
a dram chip and a couple of op-amps bolting on to it to go up to 800ms
and I
 fancy stringing about 16 of them together with feedback paths
everywhere to
make a nasty monster noisemaker thingy .... :-)

Cheers,
           Robin.
