Heheh, I convert enemy part stuff all the time. It's not very hard to do, just a little tedious if you have, say, four or five things to convert. Both here and PSOW have good guides about it, but if you need an explanation from me I'll gladly give it.

... Oh, wait, I will anyway no matter what you tell me. :p If you look in the Guides section of this site, it'll say:

Dr. Montague can convert enemy parts into weapons and armours for you, the problem is he is only found in certain quests. he is located in DR. OSTO'S RESEARCH and UNSEALED DOOR quest. Once you have started any of these quests you can find him around the main teleporter standing. You can convert items on any difficulty.

Basically, what I did was I completed all the quests to make them replayable, which is obviously a requirement to convert, then I did just as it says. I brought my nasty enemy body parts to the funny-looking man and he brought me back weapons. It's the same on I&II and Blue Burst, I have no idea about any of the other games.
