Re: What has happened to Firefox add-ons?

We'll see. Not everything on the internet is true :shock: They might be motivated to fix it because there are still a lot of XP installs and they just upset the majority of the FF userbase. I am already annoyed by the ever increasing bloat of FF & I am not alone. It won't take much for lots of user...

Re: What has happened to Firefox add-ons?

I read ESR patches are in the pipeline too. Including 52.9.0 which is the last XP version - which is borked too. That surprises me as 52 was EOL last year. The update for the current ESR is out (60.6.2) and has come through on the Debian repo in the last hour or two. I assume other linux distros ha...

Re: What has happened to Firefox add-ons?

The full update to fix it has been pushed now (for those who have 'studies' disabled). Doing a manual check from About Firefox should get it if it's not updated already.

Re: What has happened to Firefox add-ons?

Disabling the signing check through the config only works on the 'Developer' and 'Nightly' versions on Windows. Not on the 'Release' build. It also works on the ESR version shipped by Debian.

I never lost mine in the first place, but both the "studies" delivered hotfixes were applied fine.

Re: Add switch to dual drives to allow booting from either/or?

You may be thinking of the mod that some people do for Spectrum +3 external drives which just grounds out a pin causing the drive select to be overridden instead of properly swapping lines? That shorts the output of a 74HCT04 inside the machine. :shock:

Re: BBC ADVANCED TELETEXT RECEIVER

As far as I'm aware all the ATS+ ROMs are for the GIS adapter. TFS and ATS ROMs are for the Acorn adapter.
ATS+ is clearly based on ATS to some degree as the menus look the same etc.

EDIT: though if there's versions of ATS for the Morley adapter then they're different too, I've not seen those!

Re: Teefax - A nostalgic return to the days of teletext

Nope, wasn't that. Just a bug that was being tripped by that page. The server only looks at OL and PN lines - using PN as a page separator (and nothing more). Oh, you might want to look at SC too as there might be some pages without a PN for every subpage. As you've probably realised tti is a prett...

The news pages are generated automatically by a script.

Re: Teefax - A nostalgic return to the days of teletext

One thing you might want to implement is a command for entering a specific subpage number, so if the user types something like "S0003" it will try to load the third subpage. (similar to the function of a time/text button on a TV remote but without all the waiting around)

No worries. To be fair, I've only tested it with one client, the Telstar client I wrote to accompany Matrix Brandy BASIC. A couple of limitations - Fastext is NOT supported (as it uses the out-of-bounds-for-viewdata 25th line) - and there's no page loading delay! I've also put a 15-second delay in ...

I'm certainly not criticising them. I'm instead rather curious.
I'm assuming it's glitch art, which is somewhat popular with some teletext artists.
