re sigma designs double up jap po cwru edu joseph a pellettiere writes i am looking for any information about the sigma designs double up board all i can figure out is that it is a hardware compression board that works with autodoubler but i am not sure about this also how much would one cost i ve had the board for over a year and it does work with diskdoubler but not with autodoubler due to a licensing problem with stac technologies the owners of the board s compression technology i m writing this from memory i ve lost the reference please correct me if i m wrong using the board i ve had problems with file icons being lost but it s hard to say whether it s the board s fault or something else however if i decompress the troubled file and recompress it without the board the icon usually reappears because of the above mentioned licensing problem the freeware expansion utility dd expand will not decompress a board compressed file unless you have the board installed since stac has its own product now it seems unlikely that the holes in autodoubler diskdoubler related to the board will be fixed which is sad and makes me very reluctant to buy stac s product since they re being so stinky but hey that s competition stan kerr computing communications services office u of illinois urbana phone email stankerr uiuc edu
