Re: Premier's Sprite Graphics Board
I've a couple of issues to overcome - in addition to the regular things like kids and other distractions - but I'm going to try. 1. Apparently it only works on the Dragon 32. I need to unearth my boxed one to see if that is still working, as the one I have in the bedroom has a bad power board (and m...

Dragon Data logo in scalable vector format
I've attached some vector recreations of the Dragon Data logo I created back in '96, but I no longer have Corel Draw to open them and convert to something else. The online and free converters don't like the files - they could be corrupt, but it could be that they just don't like the vintage. I origi...

OS9 disks: Prolog and various utilities
I found these on a backup CD I created back in 2002, and it looks like I ripped them back in 1997. They are in a raw disk I believe, formatted as OS9 and can be viewed (and files individually viewed and extracted) using "EmuDisk" from SourceForge. Metasoft Prolog by Chris Jolly NDUG OS9 Utilities Sw...

Steve's Electronics EPROM Programmer
Photos and a ROM dump of the Steve's Electronics EPROM Programmer.
I've not used this board since 1993, but it worked fine back then for blowing DosPlus and DosDream IIRC.

Re: Premier's Sprite Graphics Board
That's fantastic! Given that the DU article didn't have any screenshots, and that Premier went bust right when the article went to press, that might be the first time anyone outside of Justin Johnson, Premier and Brian Cadge has seen it

Re: Premier's Sprite Graphics Board
The Sprite manual says the chip is mapped at E000 and E001, and to EXEC &HE002. With f9dasm it looks like I should be able to do "f9dasm.exe -begin e002 -offset e000 sprite.rom > sprite.txt" to get it to dissassemble from byte 2 onwards (I also tried -begin 2, etc) but it always produces the same ou...

Re: Premier's Sprite Graphics Board
I did download f9dasm to try and disassemble, but I couldnt remember (or find) what the offset was for where addon carts start executing. I don't think it is right at 0xC000 (start of the ROM), or is it?
