What is BASIC (although not an OS in the modern
sense, but a complete instruction set nonetheless)?
BASIC (Beginner's All-purpose Symbolic Instruction Code) was
more than an entry-level programming language. It was part of the
instruction set (not quite an OS) for early home computers like
the TRS-80 Model III running on TRS-DOS or NEWDOS and Commodore 64
(C64) running on the ROM-resident OS named KERNAL
(misspelling of kernel).
I remember reading lots of books on BASIC and Byte
magazine as well as watching Bits and Bytes on channel 13
(WNET/PBS, 1983-1984). My experience at school was on a TRS-80
Model III without floppy drives installed so there was no way to
saved any code. My experience at home was somewhat better spending
many hours in front of my C64 and no sleep, but none of the code
has survived as I could only save to a Commodore 1530 C2N
Datasette (cassette tape recorder, possibly the most unreliable
medium). This is why I can only concentrate on my experience of
BASIC on the C64.
Commodore 64 (C64):
Commodore 64 (C64)
was one of the first computer systems that I ever used and the
first one I ever owned (1984). I quickly got up hooked into a
whole new field and style of life — geekdom —
while coding source code instead of sleeping. KERNAL and
Commodore BASIC 2.0 in its 8-bit glory for the C64 boasting a
1.023 MHz MOS Technology microprocessor and 64 KB of RAM gave and
experience was as close at it could be for any kid n the early
1980's (1984, in my case). To make things even more exciting and
bringing more curious kids (like me at the time) to computer
science, the C64 was heavily used for games and even some music
programs thanks to its ground-breaking technology based on two
chips by MOS Technology — SIC 6581 and VIC-II. Commodore
International declared bankruptcy and closed shop in 1994. In
2011, a new reincarnation named Commodore USA released updated
versions of the C64 (C64x) with the same vintage (old, obsolete,
ancient, historical, retro) "breadbox" exterior
and VIC 20 (VIC Slim) with their own Linux distribution named
Commodore OS based on Linux Mint. I had not been thrilled about
any new system and/or other technologies for a long time. The
whole idea of reviving the C64x had me like a little kid before
Christmas with a new toy wrapped in front of him, but I never
bought one. Commodore USA closed shop a little after one of its
owners died around 2012.
For those of us who want to relive the heyday of the C64
(1982-85), Retro Games (England) a new version of C64 was released
in 2018 called The C64 Mini marketed as a video game console with
64 built-in games and shipped with its own joystick. According to
the vendor, The C64 Mini can also be used to program Commodore
BASIC (forked from Microsoft BASIC) — the first programming
language that I ever learned. Needless to say, I am stoked.
10 INPUT "WHAT'S YOUR NAME?"; NAME$
20 PRINT "HELLO, "; NAME$;
30 INPUT ", HOW ARE YOU? (OK/NOT)"; OK$
40 IF OK$ = "OK" THEN PRINT "GLAD TO HEAR THAT."
50 IF OK$ <> "OK" THEN PRINT "TOO BAD!"
Another nostalgia option was Manomio's licensed emulator for
iOS — iPhone, iPod and iPad. This emulator was almost as
good as the C64.
Unfortunately it has been almost thirty (30) years since I last
coded my last program for the C64 and I hardly remember how to
code a quick and dirty (not to mention descent) program (excluding
the one above), but I would consider it the geekiest purchase I
have would ever make. Of course, if you are merely interested in
C64 games, you can get a ROM emulator and a handful of ROM images,
which may be illegal in some areas and/or under special conditions
(17 U.S.C. §
§ 117 . Limitations on exclusive rights:
(a) Making of Additional Copy or Adaptation by Owner of
Copy.—Notwithstanding the provisions of section 106, it is not an infringement
for the owner of a copy of a computer program to make or
authorize the making of another copy or adaptation of that
computer program provided:
(1) that such a new copy or adaptation is created as an
essential step in the utilization of the computer program in
conjunction with a machine and that it is used in no other
(2) that such new copy or adaptation is for archival
purposes only and that all archival copies are destroyed in the
event that continued possession of the computer program should
cease to be rightful.
BASIC on i286 and prior machines came burnt to a ROM chip.
There was no way users could install or upgrade BASIC. On boot, it
loaded from the built-in ROM to RAM.
Later machines would run a stripped-down version of DOS and have BASIC as a stand-alone
executable like QBASIC.EXE (QuickBASIC), but by no means
an OS or similar instruction set. Modern distribution of BASIC
like FreeBASIC can be installed as
third-party applications in modern versions of Windows or other operating systems
