That image reminds me of my Apple Logo turtle days.

lol! but yeh I programmed the Z80 in asm to use the graphics board to draw those triangles they are not stored bitmaps from the Roms yet...

electronman32k · 11-02-2011, 09:25 PM

Finished Z80 mark 2 and got it running

placed a bitmap on one of the flash roms containing graphics for the text and then wrote some code to retrieve the characters one at a time. There is 256 different characters but I have only wrote the code to display the first 32 for now. Later I shall get it to draw up a text menu with options that can be selected/navigated with a controlpad or keyboard

Wow looking awesome. You're a psycho for doing all that on a bread board man

You need to pirate some board design software or something

Just find it really interesting that there are so few non-IC components. I guess this modern design just doesn't suffer from as much signal noise issues? It's such a stretch from a modern motherboard with exact length signal traces and tricks to minimize EMF

oh theres 100nf caps between the VCC and GND of each chip to reduce noise. I do however wish to connect capacitance reducing diodes on the data lines of that ribbon cable as there is a bit of noise on that and its why I get some transmission errors as the characters get very slightly corrupted and also the screen should be completely white after it clears it before drawing those characters but there are a few black dots that remain. Plus my FM radio goes crazy in the room If I have it on 88Mhz and then start the machine drawing those characters :p

Haha, you should record the radio in your next video

Wow, that is some interference, I thought you had the radio right next to it at first

even managed to pick up the noise from a nearby room which is seperated from my workshop by two double brick walls and a corridor between them :p

electronman32k · 12-10-2011, 06:41 PM

got a megadrive controlpad to work with it now

electronman32k · 12-10-2011, 06:47 PM

really looking forward to the xmas break so I can have lots of time to code for this and catch up on some gaming

. as well as spend some time with family and friends of course

electronman32k · 12-19-2011, 11:01 PM

Programmed this last night

electronman32k · 02-14-2012, 10:38 AM

got a color test program going. will use to help construct color palette so that bitmaps can display correctly

http://www.youtube.com/watch?v=sCshJ...1&feature=plcp

electronman32k · 02-14-2012, 11:08 AM

this is what happens without a color palette on my Z80 comp

if you mean the oooooooo thing with the white border well thats the binary value for each color

electronman32k · 02-24-2012, 11:03 AM

completed the color palette though it needs some adjustment it does look much closer to the original image

http://www.liquidninjas.com/photopos...o/2892/cat/500

electronman32k · 02-25-2012, 10:50 AM

made some adjustments to the palette. looks a bit better now.

http://www.liquidninjas.com/photopos...o=2893&cat=500

will load a color patten test into the Z80 next and use that to further iron out inaccuracy's in the palette
