Interesting ORACLE pages

Here's some interesting pages from the ORACLE recovery currently running:

I think the 777 is correct here as this will have been through hamming, but the rest of the header has probably been falsely matched by the YTV finder. The purple blocks are probably wrong too and it shouldn't be in purple graphics mode! I wonder what this was for?

This page is linked to from the ORACLE user guide. Note the hexadecimal page number so that non-Fastext users can't get to it.  Note also the difficulty the convolution process has with the letter 'p'.

The IBA has gone, now replaced by the non-descript sounding "National Transcommunications" - or NTL, now Arqiva.  The engineering pages always seemed less informative post-IBA.

This is a status page of some sort, probably for teletext but could be for transmitters.  The red Fasttext link goes off to page 5FA; the other three go to page 8FF.  I don't know what's on either page yet.

Well, that ORACLE VBI set has been running for some time now, and frankly it was a bit disappointing - more data was coming in but the page quality wasn't improving any.

I suspect that this is down to the quality of the recording not being high enough - I found a better ORACLE recording from Saturday 15 Sep 1990 so the link below now points to the output of that.  It's a lot better!

As my computer chugs away at the ORACLE data, I'll regularly (a few times a day) copy it into the website here so you can see how I'm getting on:

Back up and running

Cleaned the heads on my Betamax today, and we have a picture again!  I took a nice long grab of the tape to get the 1990 ORACLE data off.  That will keep my computer busy for a while.

In the meantime, here's a few pages from the Teletext 2005 grab I decoded whilst playing with Alistair's software.  The sub-pages with the most instances are the best quality ones.  Not bad, eh?
