The earliest
PETs had this type of data recorder built-in
but it was sold separately after the PET's
keyboard was improved. This model has no data
counter. |
The cream
version followed and is labelled as model
1530. It is like the black model except for
the addition of a tape counter. This made
it easier to find programs on the tape. |

The 1530
was redesigned and this was the model bought
with most VICs and 64s. The plug for connecting
to the computer was improved. |
For the
C16 and Plus/4 the datassette was renamed
1531 and given a black case. The connector
was changed so that 1530s and 1531s could
not be interchanged but adaptors soon appeared
on the market. |

Unlike many of
its competitors, Commodore prevented ordinary cassette
recorders being connected to its computers. Commodore's
own tape deck, known as a datassette, had a unique
connector. The idea of a dedicated cassette drive
was to make loading and saving more reliable. In
this, Commodore were probably successful but the
result was a long, long wait for a game to load.
In its defence, it has to be said that the datassette
was easy to use and usually worked well. The slow
speed of the tape was partly due to the software
or data being checked as it was loaded or saved. |

The real disadvantage
of using cassettes was in the storage and retrieval
of data. Any search had to be made from the start
of the tape. The answer of course was to use a disk
drive, but again only Commodore's own were compatible
and they were expensive. Most games came on cassettes
and blank tapes were readily available. The design
of the datassette evolved with each new computer.The
original 1530 works with the Vic, 64 and 128. The
16 and Plus/4 use the 1531. |

Microwafers
(Data drives and
wafers to same scale but not actual size). |
|
A compromise between cassette tapes and disks,
the Quick Data Drive uses a continuous loop
of magnetic tape in a plastic case. This enables
programs and data to be searched for from
the current position without rewinding as
you would need to with a cassette and at random
like with a disk. The microwafer and its tape
are much smaller than a regular cassette. |
|
The tape drive uses the datassette connector
on the 64. It can also be set up to work with
the VIC. The drive comes with its own operating
system (QOS) on a microwafer. Microwafer sizes
range from 16kb to 128kb. Drives can be daisychained
or used with a datassette. Microwaves should
be backed up as the tape can get entangled
in the drive and become unusable. |
|
With the
majority of games on cassettes, the Quick
Data Drive was not a great success. |
