Re: Oric Atmos resets after a few seconds ... when not grounded

Hi ... When i checked the mainboard i noticed that there was some work on it before: ... Mmmm strange, an Atmos with two EPROMS, It will not work with your controller. BTW, I think there is good chance that this Atmos will work with the Silicebit's controller. In my opinion this is the reason for t...

Re: Oric Atmos resets after a few seconds ... when not grounded

Thanks, Symoon! This is very interesting rom. Main differences compared to 1.1 are: - version is 1.3 A - German characters - all error messages are lower case - no key clicks - print char and read key are used trough vectors in page 2 instead of ROM calls - different CSAVE/CLOAD routines rom13a.jpg ...

Re: T-Rex game for Oric

Attached is the auto vsync code together with some standard VIA related definitions. Maybe interesting will be the 'compat.h/compat.s' too, which main purpose is to make code compatible between CC65 and OSDK. The auto vsync code is exactly coded according ThomH's message and lot of optimizations can...

Will you release Oric source code ?
For compilation are used my own make-based build system, cc65 toolchain, some OSDK tools and some LUA scripts for sprite manipulation and generation. If there is interest I can post the source code.

Re: Oric Atmos PSU Specs

This is small add-on to PSU which I bought recently and IMO is very handy! There are variants :) for Oric-1: 20170510_190852.jpg ... and for Atmos: 20170510_191028.jpg Actually it's nothing special - just a simple switch but because of laziness I never built it until I found it for $1.10 - of course...

Re: Atmoses, Microdiscs and Telestrats on ebay

ORIC TELESTRAT + Disc drive on eBay again. Who will guess the winning number this time? :).
But more interesting are the 3-inch floppy disks - take a closer look at their labels (in description at bottom of page)....
If only it were true ... CP/M for Oric :mrgreen:

Re: Which EEPROM chip should I get to burn a new ROM?

Yes, everything looks fine. One ROM on socket I think there will be no problem.
Get the MiniPro TL866 CS - it work really well (btw, the CS can be hacked to A model, but this is another story :)).
Don't forget to post the results here.

Re: Which EEPROM chip should I get to burn a new ROM?

If you decide to use AT28C256-15PU (from your eBay link) just as new single ROM (i.e. without using the available space to have more than one ROM) you have to write data in the second half or simply concatenate twice the ROM image and write it to the whole space. Here I mean you are using 16K bytes ...

Re: XA: * manipulations

As described in XA man page : To explicitly declare redefinition of a label, place a - (dash) before it And this code is working for me: .text * = $400 #define pstring(s) -_start=* : .byte _len,s : -_end=* : -_len=_end - _start - 1 pstring("TEST1") pstring("TEST2") The result is: 0x00000000: 05 54 4...

Re: XA: * manipulations

This definition:

Code: Select all

* = $400
#define pstring(s) .byte _end-_start : _start=* : .byte s : _end=*
pstring("TEST")
is assembled as:

Code: Select all

0x00000000: 04 54 45 53 54 -> .TEST
Is this what you are looking for?

Re: xa and o65 format (and CC65)

IMHO, having option '-cc' is the best solution for everyone!
The change in 'xa.c' is minimal and easy: ;)

Code: Select all

	  case 'c':
		/* fmode |= FM_OBJ; */
		fmode |= ((argv[i][2]=='c')? 0x0800 : FM_OBJ);
		break;
