Hi ! I have several Pro 350 and a Pro 380 mostly with RD53 . I also have a Vax Statin 2000 with TP and extra Harddrive. This has two RD54 installed. The sad thing is a non working Decna-K in one ofthe Pro's . I therefor am on the lookout to buy a Decna-K card. Please give me a note if you can help .
