Well "sketchy" means shady or conspicuous, I'd say you mean "slightly lacking" because there's nothing dangerous about PT-1210 .
Seems it means something different on different sides of the pond:
sketchy
adjective
1. not thorough or detailed.
"the information they had was sketchy"
synonyms: incomplete, inadequate, limited, patchy, scrappy, bitty, fragmentary, rudimentary; More
2. (NORTH AMERICAN informal)
dishonest or disreputable.
"once the story does come out, the fact that you tried to hide it will seem sketchy"
Over here in UK it's the first one
The requirements may not have been clear and I can correct that on the web, but basically it is because you don't need anything but an Amiga. Why did you think a parallel cable was needed if it wasn't mentioned anywhere?
Yeah that would be useful, brilliant news too. Maybe because I always needed one when linking two Amigas for music (Octamed etc.) back in the day. But nice to hear that, will give it a download this week.
