Model number is SyQuest SQ100, so you should check EBAY regularly for that.P.S. I would LOVE to find a 5MB cartridge for the Syquest drive to try that out but those appear to be VERY hard to find.
In the past, I was able to find rare things through persistence, although I've not done that for a number of years now. Even so, I did search Craig's Lists too, as I have family in California which helped me out with acquisitions I could not have otherwise made from my residence in Japan.
