Part four already? Memory -- that thing where the more you've got, the better things are for your computer? Yeah, that stuff. We'll be upgrading this vintage computer using a bit more modern tech to get it up to a whopping 16K. Oh, and there's a bit of gold in this story too...

If you’ve been following along, you may recollect that this journey to modernizing my vintage Timex Sinclair began when I watched this four-part video series by The Byte Attic, and decided ‘yeah, that looks like something I could do’. If you’re jumping in at this point, well, I’ve done things and have more things to do. This post will look at converting the video output of the computer from an RF signal to a more modern composite video signal with a simple hardware modification.

As I'd mentioned in my previous post in this series, I've been poking around my TS1000 a bit and doing some online digging.  I found this series about refurbishing and upgrading a Sinclair ZX81. And since I wrapped up my last post testing the that unit is still alive and kicking (I think. Video is still a thing to verify with the MK One eyeballs, though it looks good in the multimeter), it's best to jump on to the next stage. Upgrading the power converter.

#retrocomputing has been taking up more of my attention recently. Specifically, I found this series about refurbishing and upgrading a Sinclair ZX81. Since the Timex Sinclair 1000 is essentially a ZX81 that jumped the pond (and doubled it’s native RAM in the process), I’ve got one. And it’s been sitting in a box for 20ish years, used heavily previous to that. Time to rectify (ha!) that situation.
