The Atari 8-bit family had their own Atari BASIC that was modified in order to fit on an 8 kB ROM cartridge.

The first compiler was for BASIC ( 1982 ) when a 4. 8 MHz 8088 / 87 CPU obtained 0. 01 MWIPS.

Toward the end of the PDP-8 era, operating systems such as OS / 8 and COS-310 allowed a traditional line mode editor and command-line compiler development system using languages such as PAL-III assembly language, FORTRAN, BASIC, and DIBOL.

* ROM: 8 KiB ( Microsoft BASIC )

The single-user BASIC used several overlays to provide the full functionality of the language ; when OS / 8 was booted from a DECtape, a very noticeable delay occurred each time BASIC was required to switch overlays as they needed to be read from tape.

Performance-wise located between the VIC-20 and 64, it had 16 kilobytes of RAM with 12 KB available to its built-in BASIC interpreter, and a new sound and video chipset offering a palette of 128 colors ( in reality 121, since the system had a 16 base colors and 8 shades but black always remained black, with all 8 shades ), the TED ( better than the VIC used in the VIC-20, but lacking the sprite capability of the VIC-II and advanced sound capabilities of the SID, both used in the C64 ).

It featured 2. 048 MHz Intel 8080 CPU, 48 KiB RAM, 8 KiB ROM with built-in BASIC, good keyboard ( compared with PMD 85 ), monitor video output ( but not TV output ) with 288 × 256 resolution, 4 colours.

While Atari BASIC came on an 8 KB ROM cartridge, BASIC A + was delivered on floppy disk and took 15 KB of the computer's RAM, leaving 23 KB available for user programs in a 48 KB Atari 800.

Based on a Zilog Z80A CPU driven by a television colour burst crystal ( 3. 5795454 MHz ), it offered 16 KB of ROM containing Microsoft BASIC Level II, 8 KB RAM and four-colour graphics at a resolution of 128 × 64 or 64 × 32, or 32 columns and 16 lines of eight-colour text.

When manipulating the screen in BASIC with the LINE command, one easily could exceed the limit of max 2 colors per 8 × 1 area and end up with " color spill ".

BASIC 8. 0 provided commands lacking in BASIC 7. 0 to generate ( color ) graphics in the C128's high-resolution 80-column mode ( 640 × 200 pixels ) for RGB monitors.

The BASIC 8 package was developed by Walrusoft's Louis Wallace and David Darus, with contributions from Ken French ( printer drivers ) and indirectly from Richard Rylander ( who allowed his 3D solids commands for the C64, originally published in Dr. Dobb's Journal, to be converted to the C128's hi-res mode ).

It has 32 kilobytes of RAM, and its ROM includes BBC BASIC v2 along with its operating system.

Some clever program counter catches meant that the ordinary system ROMs and any software using the OS calls could function without significant modification, making substantially more memory available for BASIC, View, Viewsheet and almost every other business application.

Additionally, the last bytes of both the BASIC ROM and ' Plus 3 Interface ' ADFS v1. 0 ROM include the word

Applesoft BASIC was a dialect of Microsoft BASIC supplied with the Apple II series of computers.

It superseded Integer BASIC and was the BASIC in ROM in all Apple II series computers after the original Apple II model.

It was also referred to as FP ( from " floating point ") because of the command used to invoke it instead of INT for Integer BASIC.

Applesoft BASIC was supplied by Microsoft and its name is derived from the names of both Apple and Microsoft.

Apple's customers were demanding a version of BASIC that supported floating point calculations.

As Steve Wozniak, the creator of Integer BASIC and the only person who understood it well enough to add floating point features, was busy with the Disk II drive and controller and with Apple DOS, Apple turned to Microsoft, who was the BASIC vendor of choice after their success with Altair BASIC, and licensed a 10 KB assembly language version of BASIC dubbed " Applesoft.

" Apple reportedly obtained an eight-year license for Applesoft BASIC from Microsoft for a flat fee of $ 21, 000, renewing it in 1985 through an arrangement that gave Microsoft the rights and source code for Apple's Macintosh version of BASIC.

Applesoft was similar to ( and indeed had a common code base with ) Microsoft BASIC implementations on other 6502-based computers, such as Commodore BASIC: it used line numbers, and spaces were not necessary in lines.

Conversely, Applesoft lacked the ( remainder ) operator that had been present in Integer BASIC.

No provision was added in the 128 kB Apple IIe and Apple IIc models ' BASIC interpreters for the new machines ' extra memory and double-resolution graphics, or for the Apple II's 16-color mode.

Apple Business BASIC shipped with the Apple /// computer.

* There was a well-documented bug in Applesoft BASIC that could actually crash the interpreter if ONERR GOTO was in effect and numerous program errors occurred.

Routines that needed to be as fast or required direct access to arbitrary functions or data in memory could thus be called from a higher-level interpreted BASIC program.

Additionally, these lower-level functions could be programmed to read the data immediately following the "&" or " USR " command, allowing a BASIC program to pass parameters to the functions.

* Both Integer BASIC and Applesoft used tokenizing to reduce the memory requirements of programs and to speed their interpretation.

MSX BASIC version 3. 0

It was possible to increase the speed of the computer by using POKE 65495, 0 which accelerates the ROM-resident BASIC interpreter, but temporarily disables correct functioning of the cassette / printer ports.

** MSX BASIC V2. 0 or V2. 1 ( 16 KB )

** MSX BASIC V3. 0 ( 16 KB )

** MSX BASIC V4. 0 ( 16 KB )

The ROM resident BASIC 3. 5, however, was more powerful than the VIC-20's and C64's BASIC 2. 0, in that it had commands for sound and bitmapped graphics ( 320 × 200 pixels ), as well as simple program tracing / debugging.

Many BASIC extensions were released for the Commodore 64, due to the relatively limited capabilities of its native BASIC 2. 0.

MSX BASIC version 3. 0

A very interesting extension to the MSX BASIC 1. 0 / 1. 1 was Screen IV, a tweak of MSX BASIC adding the mixed graphic / text mode Screen 4 ( hence its name Screen IV ), with 64 x 24 characters and Screen 2 resolution for graphics ( 256 x 192 pixels, 16 colors ).

THEOS 4. 2 used THEOS BASIC version 32 Ver 2. 0, while THEOS CORONA ( Ver 5. 0 ) uses version Multi User Basic 32 / 64 Ver 2. 1.

GFA BASIC ( as of version 2. 0, the most popular one ) was, by the standards of its time, a very modern programming language.

Modularization was only rudimentary, making GFA BASIC 2. 0 best suited for small and medium-sized projects.

GFA BASIC 3. 0 included a number of improvements over 2. 0 ( including support for user-defined structures and other agglomerated data types ), the final released version being 3. 6.
