Re: Sources for Disk Controllers

More perversely (being quite ignorant of the internal workings of the current DOS variants) - what would it take to create an IDE interface? It's been a mighty long time since I studied operating systems and the only big stumbling blocks I can think of are the block/side/segment addressing basics an...

Sources for Disk Controllers

I'm trying to maintain the excuse of keeping my trusty D64 on the basis that if I can get a disk controller I can actually do some practical things with it but obtaining a disk controller is proving entertaining (if I can abuse the word in this way). Having sat on ebay for months I've only seen a fe...

Re: Trekboer by Microdeal

The big advantage with the Amiga is that it was easy to achieve thanks to a dedicated video processor and most importantly a blitter chip that in a fair number of circumstances was more powerful than the 68000 the computer used. The real beauty was they worked in parallel using shared memory so you ...

Re: Prince of Persia

The actual game code is quite compact already in terms of volume - the bulk of the game and data (some 250k) is graphics, sound and level design. Each level is actually very compact using large tiles so not much to save there. The sound could be thinned out both in terms of the number of different s...

Prince of Persia

Somewhat off-topic but potentially of interest here to those that like their classic 80's coding. Jordan Mechner - creator of the original Prince of Persia on the Apple II has posted the source code on github after finding tucked away in the back of a closet. It's all in 6502 assembler but any self-...

Re: Dragon keyboards.

At least you have the opportunity to rectify the problem if you feel like correcting the oddities :)

Re: The Ring of Darkness by Wintersoft

Good though the game may have been it is more-or-less a simple rip-off of the original Ultima and chunks of Akalabeth (the predecessor to Ultima). It is of course a great game in its own right despite the derivative content. The real star of the show is that it was written in basic and still managed...

No mention on the wiki about the later versions of the game (Atari ST, Amiga and DOS)...
Not particularly relevant here of course but it is one of the great(ish) success stories of coco/dragon gaming

Re: Software available to convert Basic to M/Code on the fly

I distinctly remember having a basic compiler for this very purpose. It wasn't hugely brilliant and the speed improvements while present weren't what I'd hoped for - it was one of the reasons why I taught myself how to use assembler in the first place. I tried other languages as well but they were e...

Re: Got it all back - at last

Assembler (no idea which one) [difficult to tell if you don't know which one!] I believe it would just take loading it once to make sure, or LIST-ing it to see if any Copyright information will be displayed. Lunar This one is most likely to be "Lunar Rover Patrol" (Dragon Data). While I don't have ...
