Re: introducing myself

Hi Martijn, Nice to see someone else who is starting from scratch and learning something entirely new to them. I do have some previous experience in web coding languages, so that sometimes helps me. Although, learning z80 ASM is quite the different language compared with PHP and MySQL. I look forwar...

Re: Changing Hex in memory to Decimal on screen

I found the issue!

wait for it.

there was a missing ret command..

so happy to have found it.
Was just doing a bunch of break points and watching the program counter.

Re: Changing Hex in memory to Decimal on screen

Thought i'd post a little on what I've been up to to try solve this without BCD. Every time I tried to watch the video you have on BCD it turned out to be very late and I couldn't concentrate. However, after sleeping on my issue I came up with another solution (I thought). This was to do some >= sta...

Re: Changing Hex in memory to Decimal on screen

Thank Keith,
I'm watching your bcd video now. Hopefully i'll understand that and be able to use that to fire numbers on screen.
although i'm not sure if that will cover the printing of each number.
I'll let you know how I get on!
:Cheers:

Some more Newbie questions

Hi hi. It's been a while since I had time to even think about the program that i've been "writing" for months (aka. doing a few lines then putting it away for a few weeks and then coming back to it and doing a few more lines. Over and over.) I'm looking to draw some images and have managed...
