Help. Very old DOS game (Around 1986).

I use to own an play a very old DOS game simply called "Asylum" on a PC XT about 20 years ago.

It was in essence a text adventure game (North, South, Look, Open Door), but with ANSI ****graphics. You started the game in a cell and the object of the game was to escape.

Most websites never mention that the game was ever released on the PC, instead referring to TSR 80, C64, Atari 800 releases.

I did manage to find one website with an image of the game box, on the back is you look closely it does mention PC.

Does anyone know where I could find more information on this game?

Yeah I found that same link, I think it was linked to from Wikipedia.

In regards to what information I am after, I really can't be specific. Anything information pertaining to the PC version though would be great.
