Re: Help with two Orics

Else there still IC20 which can be put on socket and changed :). I'm quoting my message 'just for the record' ;). Congrats for the good work and many happy Oric-hours! Can you update us: what's exactly the current condition of the second faulty board? What's seams to work and what not? Which tests ...

Re: The Hobbit: Disk, Erebus,...

... please tell us Well, about 'The Hobbit' - I can say it's fully ' Spanish job ' ;) : from @Silicebit 's DSK using @overCLK 's Oric DSK Manager I extracted the only file HOBBIT.COM and noted the start address (#4FE), then I added a TAP header and .. that's it! :) Here I don't really recall if I m...

Re: The Hobbit: Disk, Erebus,...

Things started at The hobbit on disc! by @Silicebit. :)

Attached is the executable - extracted from DSK and converted to TAP (indeed, start address is #4FE).
The game starts "as is" in Oricutron and seams to work, so I expect it will start with Erebus too.

Fixing Oric Nova64

This is replay to @Dbug 's post in Oriclopedia: A series of videos on all things Oric about Oric Nova64 machines. Regarding the machines... what I can tell you is that the motherboard uses 2 memory chips (tms4464-15nl) instead of the usual 8, and nowhere is written "Designed by Tangerine Computer Sy...

Sorry again to revive an old thread...
There is nothing wrong to dig in old threads, actually your message helped me to notice now a small difference between Atmos and Nova64 - see picture ;).

Re: Oric Fonter - quick tool for Oric fonts [raxiss]

Well, the selected samples will not work. The tool accept as input full charset definitions only in plain binary format or with added header as valid TAP file. More precise you can use binary files with exact size of 768 or 1024 bytes, or TAP files which contain such binaries or with start address i...

Re: How to use MACROS with OSDK

@coco.oric: The short answer is: don't #include 'macro.h' coming with OSDK. It's used internally by the C compiler.
To experiment simply use #define in your assembler code. And a humble advice: use simple macro definitions because lot of side effects are possible which are very hard to debug. ;)

I'm not sure which version of BD DOS it is?

The HELLO program reports version 2.2. Any information is wanted and highly appreciated, please!
Manuals and even some pictures of the hardware are real treasure :).

Re: first address read after Oric power on

What is the first address that Oric 6502 execute in memory after cpu power on? After power-on i.e. after RESET the CPU reads address stored at location $FFFC and $FFFD and jumps to that address. For instance in Atmos ROM v1.1b: at $FFFC is 8F and at $FFFD is $F8, so the CPU will start at $F88F. You...

Re: Is BD-DOS lost to time?

One more step further with last Oricutron support of Byte Drive 500. :) BD-500 emulation works with Oric-1 ROM 1.0 and with the Atmos ROM 1.1b. THIS is the current portion of code handling the I/O read operations from BD-500 hardware. Most interesting is how read from address 0x317 affects the memor...
