Re: DIY: 80 column WordPak board (CRT9128)

I believe that Luis's driver is an adaptation of the original 1984 WordPak driver source code which is documented on page 17 here:

Re: DIY: 80 column WordPak board (CRT9128)

Hello, a bit more info about that mod. When I run a basic program that has as the very first line a CLS, and immediately there is a PRINT something, this text is displayed the same wrong way as the OK. I mean that the first letter of the text is displayed at column1, but the rest goes from column 5...

Re: DIY: 80 column WordPak board (CRT9128)

Some monitors have overscan issues with the WordPak board resulting in a few missing columns on the left and/or right side. The attached basic driver (source code and HDBDOS dsk image included) compensate for the overscan problem by creating left and right margins. The margin width can be adjusted u...

Re: DIY: 80 column WordPak board (CRT9128)

Hi pere,
The WordPak's video output is composite video (same as the Dragon's monitor output) and not RF.
You should connect it to your monitor's composite video input. If your monitor only has a SCART input you need a composite to SCART adapter.

Re: Anyone able to identify this board?

Apparently, the Dragon 64 has this logic already built-in. It's just struck me whilst looking at the Dragon 64 circuit diagram, that the board was obviously an improvement as it's included in the Dragon 64 circuitry (IC14 & IC13A). Just looking to maybe try and convert my Atom RGB board to work on t...

Re: HDB-DOS for Dragon 32 and 64/Tano

Cheers- the image worked, but as you say Out of Memory errors were pretty common. I can see that this is a bit of a problem without a burned EPROM - limits the use a little bit i would have thought? i take it from that most folk have a burned imaged then. hmmm... Yes, to get the most out of HDBDOS ...

Re: HDB-DOS for Dragon 32 and 64/Tano

OK, since you are loading HDBDOS to RAM at $6000-$8000, any game that loads into that memory area is likely to crash. HDBDOS is much more useful when burned on an EPROM cartridge. You could write some code to load the game at a lower memory address, detach HDBDOS, relocate the game and run it. Check...

Re: HDB-DOS for Dragon 32 and 64/Tano

saying that, still trying to get the DIR to actually give me a directory tho. another school-boy error i assume. Make sure you are using DECB (CoCo) formatted disks. HDBDOS can't read DragonDos disks - they must be converted to DECB format. Here is a sample converted disk. RUNM "EDDIE.BIN" should w...
