Re: Composite to HDMI Converter

eBay is full of ones like this from China. AVtoHDMI (600 x 600).jpg Some folks avoid the Chinese stuff like the plague, but for the price it's hard to go wrong. I use one with my Texas Instruments TI-99/4A, which is rather demanding--the "composite" video is taken from a cable that was meant to feed...

Re: Improving Timex/Sinclair Tape Loading

I never make mistakes. Once I thought I'd made a mistake, but it turned out I was wrong. :P

Seriously though, I'm glad to hear another dubber is on-line. Can't wait for Lardo to turn it loose on those "unrecoverable" tapes and see how many can be rescued.

A regular ZX81 16K RAMpack should work with Lambda 8300.
I concur. My Lambda, (insipidly named "Your Computer"), uses a Timex 1016 RAM pack I have left over after doing the 32K mod to my ZX81. It works just fine.

Re: Direction of current flow

Mostly people mean the technical direction when talking about current flow which is more historical or conventional but not very precise. I wonder if it's a cultural thing which depends on which side of The Pond you're on. I was taught to think of current in terms of the flow of electrons, moving f...

Re: Improving Timex/Sinclair Tape Loading

That's a nice looking board you're working on Lardo--much better than my cobbled together effort. I'm excited for you. You've answered most of your own questions. Refer to the circuit diagram for the rest, as "top" is somewhat arbitrary. The stripe on the diode goes where the "line" is on the circui...

Re: Direction of current flow

The stripe on the diode goes where the "line" is on the circuit diagram. (I think of the symbol as depicting an "arrow" hitting a "wall", showing the direction in which current can NOT flow.)

Looks like you're almost there,...

Re: Pictures of Our Babies.

Wow! :shock: Those are some pretty serious looking machines! Well done, all. I wish I spoke (read) German to know what the heck those behemoths actually do.
