We were aware that this information hasn't been available on our homepage but we have now updated the homepage and our other information material, including the product flyer [151KB PDF file - click to view, right-click to download - Ed].
Bubba is our own design. It is based on a 200MHz ARM9 CPU (Atmel's AT91RM9200) and has 64MByte of SDRAM. Since it is completely networked it has no graphics. It has no FireWire but does have one USB device and one USB host connector.
The print server is based on CUPS and Samba. Since we only have USB connectivity we only support USB printers that implements the USB print class. This, however is to our knowledge, all major brands.
We have both CUPS and Samba set up to use raw print queues and hence only forward data to the printer with minimal intervention. This in turn means that the end user uses the Samba exported printer and installs this device driver locally. We have yet not had any problems with this setup. Of course, if you have a low-budget Win-printer it most likely won't work.
We have in our pipeline - however a bit away - a new platform with, among other things, gigabit Ethernet, more memory and a faster (400-500MHz) CPU .
Closer yet is a mini version of Bubba. Same functionality but based on a 2.5in disk. (Unfortunately, the storage capacity will, of course, be smaller).
When we developed Bubba, the correct choice of hard disk was around 250GB. We most likely will follow the price development here and we will upgrade this offer with bigger disks.
We unfortunately cannot support users that want to replace their hard disks. One reason for this is that connectors on normal 3.5in disks seem not to be standardized. Not all disks will fit into our casing and connectors.
However, it is possible to change disks but the warranty will, of course, be voided. We do provide a downloadable install image for reinstall purposes. This image is placed on a USB stick/disk. This device is then used to boot Bubba. The image will then do a clean, fully-automated, base install, including partitioning etc of Bubba on the attached disk.
