Does anyone here actually have a DoubleUp Board?
Posted by: olePigeon on 2020-09-30 14:44:10 Was watching old Computer Chronicles episodes, and they had a fun segment with Stuffit and DiskDoubler. I had no idea that there was a hardware option for DiskDoubler. Does anyone here have one? It sure looks like fun.

Posted by: ArmorAlley on 2020-09-30 17:24:04 DoubleUp card I want one of those. Something for my eBay searches then. I had never heard of cards to aid disk compression/decompression. DiskDoubler was my preferred file compression utility back when I carried around diskettes everywhere with me.
Posted by: LaPorta on 2020-09-30 21:49:53 I assume that just speeds up the process exponentially when used in conjunction with the software?
Posted by: olePigeon on 2020-10-01 00:58:47 @LaPorta Yeah, it allowed for exceptionally fast compression and expansion. You could even set up partitions (or just the whole drive, apparently) that would automatically compress and decompress everything as you used them on the fly. Not quite real-time, but fast enough. It had intrigued me as an actually very useful card for archiving software. I had already sort of standardized on Stuffit, but I never new that DiskDoubler used an open compression standard. That seems like a better alternative since theoretically a DD compressed file can be reverse engineered and even decompressed on a PC without any proprietary software.
Posted by: Unknown_K on 2020-10-01 02:16:04 Never seen that card on ebay. I think mine came from a university haul a very long time ago. Don't think I ever used it.
Posted by: NJRoadfan on 2020-10-01 02:29:39 Not open, just one that had an available hardware chip. Stac marketed accelerator cards for use with their Stacker disk compression software for ISA and Microchannel slots. Seems that was extended to NuBus as well.
Posted by: olePigeon on 2020-10-01 02:53:30 @NJRoadfan Ah, OK. I misunderstood what they said in the show. In any event, it seems like a more universal compression that's readily available on early Macintosh computers. DiskDoubler was pretty prevalent. I think it was the most popular until Stuffit came around.
Posted by: olePigeon on 2020-10-01 02:54:34 @Unknown_K Would you be interesting in selling / trading the card?
Posted by: Unknown_K on 2020-10-01 04:13:34 @Unknown_K Would you be interesting in selling / trading the card? Not sure to be honest. I know the odds of me finding another are pretty small and I do love collecting oddball Nubus cards.
Posted by: olePigeon on 2020-10-01 08:32:19 No worries. At least I know what they look like now. Had I known a few years ago, I bet I could have found one in the box o' cards at WeirdStuff.
