VHS
Although not the ideal way to watch the original series, there is certainly a sense of authenticity and nostalgia to watching the show on VHS. Be aware that VHS releases will not have subtitles making them less accessible to the hard of hearing.

WorldVision Twin Peaks Season 1 Collection

Released in 1990 for an unknown price.
WorldVision Home Video released the first season of Twin Peaks on VHS in 1990 at some point after May 23rd (date unknown, presumably a few months after the final episode aired, the copyright on the box only says 1990 although certain sources list it as being released in 91'.) The spines of the VHS tapes spell out 'Twin Peaks'. The set came in a box resembling a wooden log however they may have been released individually as well (clarification needed).
It's important to note that this release does not include the extended pilot episode 'Northwest Passage', instead it has the originally aired 48 minutes version of Episode 1 'Pilot'.
PAL
'screen entertainment' Welcome To Twin Peaks Complete Series Wooden Box Set

Released in 1991 for an unknown price.
Can be found on eBay in the realm of £100-£150.
This PAL release of the entire series amusingly comes in a wooden crate-like box that has a sliding door to reveal the tapes. It contains the feature-length pilot episode (often named the 'International Pilot') Northwestern Passage and every episode of the first two seasons across 11 tapes.
NTSC-J
I don't speak Japanese so I am unable to aquire more information about this release but it appears to contain Seasons 1 & 2 across 14 tapes. It appears that this company also released Northwestern Passage. If you know any more information about this release please contact me.

Presumably released somewhere in 1991-1994.
