Re: memory locations for char set and what chars are where on the screen

It will most likely be powered by an Arduino but will use the 1000 for its content. It might also be cool to just show the ram blinking away in a sphere like its thinking.

memory locations for char set and what chars are where on the screen

I have two clear plastic hemispheres and I want to make a spherical led matrix powered by my 1000 and perhaps use it instead of a monitor. (wont have quite the res) where in memory is the char. set saved and more importantly there must be a place in memory keeping track of what char. is to be displa...

Re: My 1000 is on its way OHIO

Re: My 1000 is on its way OHIO

Can you make a proper video circuit? http://www.sinclairzxworld.com/viewtopic.php?f=7&t=2405&p=25270&hilit=1024mak+video#p25270 Thanks a million my friend. I thought my 1000 was a 0000 but that circuit you linked me to gave me a K at the bottom of my screen so I guess its a working computer. I cant...

Re: My 1000 is on its way OHIO

Yes I can make that. I made a little progress today. There seems to be 2 labels on the board that say USA before it goes to the modulator One was kind of hiding. So I tried that line out (the one farthest to the left) because the oscilloscope showed a more convincing pattern. When I went from that l...

Re: My 1000 is on its way OHIO

So Bummer, my 1000 arrived and it is not putting out a video signal ( at least I think.) I didn't have a TV so I bypassed the modulator by soldering to the USA line into the modulator and to the ground. then connected it to a tested composite B&W monitor. I tested the power supply and the little doo...

Re: My 1000 is on its way OHIO

Hi. Ive always wanted to understand the real 1s and 0 of electrons can be moved around to look smart and I finally found a book that made sense to me. "Programing the Z-80" If you want a really great book about how a cpu, ram and rom is working down to every 1 and 0 you can get the book But How Do ...

Hi. Ive always wanted to understand the real 1s and 0 of electrons can be moved around to look smart and I finally found a book that made sense to me. "Programing the Z-80" So one thing led to another and I ordered a 20 dollar 1000 on Ebay to mess around with. One of the classes I assist in is an el...
