	'''{{PAGENAME}}''' is a research software platform devised by American computer scientist [[User:Alexander\|Alexander Nicholi]] based on MS-DOS 6.22 and running on IBM-PC compatibles~~. Specifically, it is composed of five concrete platforms: Sirius A, Sirius B, Sirius A′, Sirius B′, and Sirius V~~.		'''{{PAGENAME}}''' is a research software platform devised by American computer scientist [[User:Alexander\|Alexander Nicholi]] based on MS-DOS 6.22 and running on IBM-PC compatibles.

	~~===Sirius A===~~		TBW
	~~Sirius A is a desktop build with the following specifications:~~
	* Cyrix 5x86 CPU @ 100 MHz
	* 1 MiB of 5 ns on-board SRAM cache
	* 32 MiB of EDORAM
	* Jetway J446A-V2.0
	* PCI-based [[Cirrus]] [[Alpine series\|Alpine]] CL-GD5480 with 64 MiB of SGRAM
	* 19" Sony Trinitron running at 1280×1024 @ 60 Hz
	* NEC FD1231H 3½" floppy drive (A:)
	* NEC FD1157C 5¼" floppy drive (B:)
	* 64 MiB industrial CF card with IDE adapter (C:)
	* Creative Labs CD5233E CD-ROM drive (D:)
	* Creative Labs CT1870 CD-ROM ISA controller card
	* Greystone dual-slot PCMCIA reader with ISA controller card
	* 3Com EtherLink III 3C509B-TP 100 Mbps Ethernet ISA controller card

	~~Sirius A deigns to run 15-bit RGB555 "high colour" at its full 1280×1024@60Hz resolution, which is double the width and slightly more than double the height~~ of ~~Sirius B. In certain programs such as [[Quindle]] and [[Senusret's browser\|Senusret's]] this will allow it to have~~ a ~~dual-column layout on a single display~~, ~~which is not possible to accommodate at the lower 640×480 resolution~~.		==Hardware==
			There are several categories of hardware that are considered for a support spread: CPUs, video cards, monitor resolutions, multimedia drives, and network stacks.

	~~===Sirius B===~~		;CPUs
	~~Sirius A is a laptop set up as a desktop, specifically the Compaq LTE Elite 4/75CX~~:		:Genuine Intel i286 @ 12MHz (GRiDCASE)

	* 32 KiB of on-chip ~~cache~~		:Cyrix 5x86 @ 100MHz
	* 24 MiB of RAM		:AMD i486-compatible chip (?)
	* Western Digital SVGA-capable chip, probably the same one in the earliest IBM ~~ThinkPads~~ (~~WD90C24A2~~ with ~~1 MiB~~ VRAM)		:Genuine Intel i686 (?)
	** This still needs to be confirmed with real world testing		;Video cards
	* 17" Compaq 151FS running at 640×480 @ ~~60 Hz~~		:IBM CGA mode 3 (80×25 text w/ colour)
	** The monitor is capable of up to 1024&~~times~~;~~768~~		:S3 ViRGE VX with at least 4MiB VRAM
	* 64 MiB industrial CF card with IDE adapter		:Cirrus Alpine CL-GD5480 with 4MiB SGRAM
	* Built-~~in dual PCMCIA slot~~		;Displays
	** This can be used to adapt CF cards as primitive "thumb drives", as well as attain Ethernet support		:CGA monitor (?)
			:19" Sony Trinitron running at 1280×1024 @ 60Hz
	~~Sirius B is set up alongside Sirius A and deigns to run 15~~-~~bit RGB555 "high colour" at 640×480@60 Hz resolution.~~		:18" Compaq 151FS running at 640×480 @ 75Hz
			;Multimedia
	~~===Sirius A′===~~		:NEC FD1231H 3½" floppy drive (A:)
	~~Sirius A′ is a GRiDCASE 1520 sporting 1 MiB of RAM and a genuine Intel i286~~ with i287 running at 10 MHz. It has a built-in monochrome screen, but this is optionally supplanted by a 9-pin EGA-compatible monitor. Like Sirius A and B′, it has a functioning 3½" floppy diskette drive.		:NEC FD1157C 5¼" floppy drive (B:)
			:64 MiB industrial CF card with IDE adapter (C:)
	~~===Sirius B′===~~		:Creative Labs CD5233E CD-ROM drive (D:)
	~~Sirius B′ is a Compaq SLT/286 sporting 2 MiB of RAM and a genuine Intel 80C286 running at 12 MHz. It has a built~~-~~in monochrome screen that supports up to 8 shades, but it looks quite terrible compared to Sirius A′ and any CRT. Interestingly, it supports a 15~~-~~pin~~ VGA~~-style external monitor plug-out. It has a functioning 3~~&~~frac12~~;" ~~floppy drive.~~		:Creative Labs CT1870 CD-ROM ISA controller card
			:Greystone dual-slot PCMCIA reader with ISA controller card
	~~===Sirius V and V′===~~		:Osprey Video 22-02028-03 PCI VGA + &frac18;" audio capture card
	~~Sirius V is not a physical computer build, but rather a virtual computer that leverages Bochs for accurate emulation of an IBM~~-~~PC that is specced similarly to the other four Sirius computer builds. It can provide x86 CPU emulation, and, crucially, emulation of a somewhat generic Cirrus Alpine series 2D accelerator graphics~~ card~~. Sirius V is indispensable for both mobilising software development on {{PAGENAME}} as well as debugging at low levels close to the hardware.~~		;Network stacks

The Prime ABI is also available to be run in the Optic ABI using a "virtual console" type approach, where it may be possible to leverage other fonts and sizes.

			==Hybridism==
			Hybrid programs are a central feature of Sirius DOS where programs can have graphical output and text console I/O together with a unified interface. In its most basic form, the kernel monopolises a special key (or keys) for use in toggling the view of the output between the graphics and the console, so no matter what the program, the same method can be used by the user to switch.

			[[Quindle]] also provides a more flexible built-in system of running hybrid programs.
