Hi, I've got every item of software available on the web for TS2068 in .TZX format and 
would like to offer it for archival on www.timexsinclair.org. I tried an email but it 
bounced. Who should I talk to?

Plus, I think the site is fantastic, but I've noticed a couple of innaccuracies:

The ROMs have nothing to do with the SCLD chip. The 'Sinclair something Logic 
something' (I used to know what it stood for) chip handles the machine's I/O (except 
the joysticks which are done via the AY chip).

The ROMs are copyright (c) 1982 Amstrad, (c) 1983 Timex. Amstrad are happy for the 
ROMs to be distributed and Timex don't know exactly what happened to the 
copyrights of their computer subsidiary and don't mind the ROMs being distributed 
either.

No it isn't. It's the AY-3-8910 which has two I/O channels as opposed to the 8912's 
single I/O channel.

I'm probably going to put the Timex titles up on my own site in the mean time but 
eventually I'd prefer to link to the page at timexsinclair.org.

Cheers!

Yes, it is. AY-3-8912 is used both in ZX128 and Timex
computers. The AY-3-8910 was used mostly in arcade
machines.

Beside both AY-3-8910 and AY-3-8912 have 2 I/O channels.
But in the AY-3-8912 the second (IOB) isn't available
outside its case.
