The PT-82 and PT-87 are almost identical. Apart from the obvious colour
differences, the PT-87 differs from the PT-82 only in that it lacks a
headphone output jack.
The PT-82 was available in a choice of colours; my example is dark
grey, but I have
seen a white PT-82 advertised on eBay, and I think I have even seen a
bright red one as well. I have never seen a PT-87 in any colour other
than grey, so I don't know if the colour options were available for
These are very basic, monophonic, semi-toy keyboards. A choice of 12
rhythms and 8 voices is available. When playing the keyboard manually,
only rhythm (consisting of 'blips' and noise pulses) is available -
there is no chord accompaniment. Despite this, the ROM-Pack music is
still rendered quite nicely, complete with chords and two-voice
In common with most ROM-Pack keyboards, the four-level "Melody Guide"
training feature is available. This teaches you how to play the
ROM-Pack tunes by lighting LEDs above each key, and blinking the light
above the key that is to be played next. White notes have red LEDs,
while black notes are indicated by green LEDs. Additionally, the PT-82
and PT-87 feature a "Rating" feature, which scores your performance,
based on how accurately you played the tune last. This uses the LEDs
above the keys as a kind of graph - the further right the LED that
lights, the higher your score for that performance. Ratings of "Try it
again", "Fair", "Good" and "Excellent" are marked on the keyboard, and
each rating class is associated with a jingle that plays after the
rating is displayed.
The PT-82 retailed for £59.00 in a 1986 Argos
Of all the keyboards I own, this is among my favourites. The simple
square-wave-based voices with minimal filtering, combined with the
simplistic rhythm and accompaniment, perfectly encapsulate everything I
love about these old 1980s keyboards. The built-in speaker lets it down
a bit, but through external amplification it sounds just gorgeous.
As mentioned above, the PT-87 does not have an audio output socket, so
it is difficult to make good recordings from it. These samples are
therefore from the PT-82, but the two models sound identical.

Both manuals were bilingual, containing English and Spanish sections.
