Sinclair ZX80 / ZX81 / Z88 Forums

For the upcoming ZX Spectrum series of episodes of the Floppy Days Podcast (floppydays.com) I would like to include a few audio clips from people who used the machine back in the day, what it means (meant) to them, and any other thoughts about the machine. Just looking for a 3-5 minute audio clip an...

Hi, guys. I'm doing an upcoming series of episodes on the Floppy Days Podcast (floppydays.com) on the ZX Spectrum. First up will be a couple of shows on the history of the machine (including an interview with John Grant of Nine Tiles). I need volunteers to co-host the other episodes, covering such t...

Wow lots of things to try! I will test all the recommended things and configurations here and get back with the group. I do not have a composite mod on this TS1000.

thanks!

Randy

thanks, guys. Glad you enjoyed it

Thank you all of you for the great information!

I will be discussing these upgrades in an upcoming episode of the Floppy Days Podcast around the end of July. This information was most helpful.
