Re: Z80 Question
If you simply change data line D1 to high and keep all other low, you would get the instruction LD (BC),A which has 2 different M-cycles, all in all 7 clock cycles long. This would end the synchronicity of refresh counter and address counter and switch address bus periodically to zero. Would give a...

Aaaah. Of course.
Cheers mate. And double thanks for noting which section in the docs I need to read - it's much appreciated.

Z80 Question
Just a quickie - because the Z80 datasheet is large and you guys are so smart that I figured it'd be easier all round just to ask. :D Little bit cheeky perhaps. ;) I have a homebuilt "computer" based around a Z80A cpu which currently has LEDs mounted on the address lines since I haven't sorted out a...

Re: 3D Printing
I've done a cartridge case for a Dragon 32 rom/ram board through Shapeways and it's not very cost effective - although they are a fantastic service which I use a lot. If you had your own printer then maybe it becomes workable, otherwise (for bigger stuff) I just regard it as a way of producing a cus...

Re: Can someone "decypher this"?
Actually... HuBASIC does have a line command which accepts parameters in a similar fashion e.g. LINE(x1,y1)-(x2,y2) so I'll double check. Edit: Can't find a suitable reference to a reserved word of CONNECT in HuBASIC. However, the coordinates in the OP do indicate a later machine than I'm trying on ...

Re: Can someone "decypher this"?
Ok... well... OP said the code came from DragonBall Z? So Japanese.
We've established it's not MSX BASIC, I'm pretty sure it isn't HuBASIC from the X1 and it doesn't appear to be X-BASIC on the X68000.
Any other ideas?

Re: Can someone "decypher this"?
The key to this is possibly that CONNECT statement. It seems to be drawing a polygon but I don't ever recall seeing a graphic function in a variant of BASIC looking like that. So couple of possibilities(?) 1. It's a polygon drawing command with a bit of a weird syntax (all the parameters separated b...
