that. In order to actually see what's on your drive, you will need the *dot command* equivalent of **CAT**, **.ls**. Indeed typing: ``` .ls ``` you will once again, see what's on your drive. Once **SPECTRUM** is used to change to 48K Mode, you cannot return to the Next mode using a command (as **SPECTRUM** does not exist in 48K BASIC). Instead you will have to reset your machine, using either the **Reset** button on the side of the computer or by pressing **NMI** together with **1**. A more complex iteration of the command is the following: **SPECTRUM** *filespec* This command loads a snapshot file in the popular **.z80**, **.sna**, **.snx**[^p190-17], **.p** and **.o** formats and runs it. 48K, 128K as well as ZX80 and ZX81 snapshots are supported. Here are some examples: To load the ZX81 classic 3D Monster Maze: ``` SPECTRUM "/games/zx81/3dmm/3dmonstermaze.p" ``` To load Pogie in Dreamworld Demo: ``` SPECTRUM "/games/next/pogie/pogie.snx" ``` To load Darkstar: ``` SPECTRUM "/games/classic128/ darkstar.z80" ``` Two more specific variations of the basic **SPECTRUM** command are: **SPECTRUM LOAD** which switches to the ZX Spectrum 128K compatibility mode and invokes the Tape Loader and **SPECTRUM 48** which switches to the ZX Spectrum 48K compatibility mode, without any access to 128K hardware features. Both of those are mostly of use to the .TAP/.TZX/Tape Loaders included with *NextZXOS*. To change colour schemes for the *NextBASIC Editor*, **SPECTRUM** can be used with one of the following modifiers: **INK**, **PAPER**, **FLASH**, **BRIGHT** and **ATTR** (which sets all the previous ones in one command). The syntax is as follows: **SPECTRUM** *MODIFIER n* where *MODIFIER* is one of **INK**, **PAPER**, **FLASH**, **BRIGHT** or **ATTR** and *n* is a standard colour from **0** to **7** when using the **INK** and **PAPER** modifiers, **0** to **1** for *disabled* or *enabled* when using the **BRIGHT** and **FLASH** modifiers, or calculated as: *(128\*flash)+(64\*bright)+(8\*paper)+ink* for the **ATTR** modifier. Here are some examples: ``` SPECTRUM INK 4:SPECTRUM PAPER 0 ``` or ``` SPECTRUM ATTR 4 ``` [^p190-17]: *The .snx type is essentially the same as .sna but instructs SPECTRUM to load the snapshot using some Next mode settings (as for example ZXN DMA instead of Z80 DMA) as it prioritises features over compatibility.*
