BASIC drawing proggy

hey all,

I've written a very simple drawing proggy to use on my unexpanded zeddy and I'm pretty happy with it.

***edit*** there is now an 'ascii' version with save and print options, too.

You litterally move the pointer around the screen with the four keys, then the T key will raise or lower the pen and allow you to draw or erase. It does everything I need really and I can get a simple picture done before it bombs out of available memory.

One thing I would like, however, is the ability to save the drawing once it has been made on the screen, and I hijacked @mrtinb's thread, to that effect. Got some good suggestions on that thread, so once I have been able to expand the RAM (either with the blank screen ram pack that i cant get to work, or with the ZXpand+ that I have pre-ordered) i will report back.

As you can see in many threads on this forum, the general problem with the 16K RAMpack is bad capacitors.

You could open it up and replace the capacitors, and that might fix your RAMpack.

I got a chance to open it up earlier and as soon as I saw them there I had a similar thought! Hoping to get some time to have a closer look at the weekend so will report back if I have any success on that front.

I have a couple of dead Sinclair 16K RAM packs you are welcome to for the price of p&p (from the UK) - there may be enough working components between them to get yours going.

Thank you so much! That would be awesome. I'm not sure if I can DM yet; will see if I can send my details now.

Thank you @Dim_75! One day I will create a masterpiece and the wife will have to let me leave the zeddy switched on forever if I can't save by then :lol:
