It looks like there’s a mix-up of two very different things in your question:

Vigora Oral Jelly – a brand of medication used to treat erectile dysfunction (contains sildenafil).

Digital Equipment Corporation (DEC) – a historic computer company that existed from 1957 to 1998 and was known for minicomputers like the PDP and VAX.

There is no known connection between Vigora Oral Jelly and Digital Equipment Corporation. Vigora Oral Jelly is a pharmaceutical product used in healthcare, and DEC was a technology company focused on computer systems. There’s no evidence that Vigora Oral Jelly was “used” by or at Digital Equipment Corporation in any official or documented way.

If your question was trying to ask something different—like when DEC used a specific technology, product, or software—please clarify the exact technology or term you’re interested in. As it stands, there is no historical record of an erectile dysfunction medication being part of DEC’s operations, products, or history.

About Digital Equipment Corporation (for context):
DEC was founded in 1957 by Ken Olsen and others, rose to prominence in the 1960s–1980s with minicomputers, and was acquired by Compaq in 1998. The company did not operate in the pharmaceutical space.
