Well, I am really impressed with the response from this list!
Thanks go to

And special thanks to
Basically there is only one player now, Tadpole-RDI which is the merger of
Tadpole and RDI.
Comments were generally very good for both the Tadpole and RDI products,
they're a bit bulky and heavy, and the battery life is not wonderful (60
minutes appears quite normal). Several people responded indicating that
they will run standard versions of Solaris with Tadpole extras for power
management and framebuffer support.
Price seems to be the only downside, although several people mentioned that
Ross Pennington from Herman Miller http://www.sqa.net/tadpole/ was selling
off excess SparcBook GX3 's for around $US800. The only downside for these
I can see is the fact that they require a 2.5inch SCSI hard disk. These
particular ones come with a 1.2Gb IBM drive, but most disk manufacturers no
longer make 2.5inch SCSI disks, and never made them larger than 2Gb. I
found 2 sites http://www.seeword.com/MonsterDrive.html and
http://www.century.co.jp/products/mac/cis2110t.html that appear to modify
2.5inch IDE disks to support SCSI for old Macintosh powerbooks, but neither
of the vendors seemed interested in selling them for non-Mac use.
Tadpole-RDI do have reconditioned hardware for sale, but only seemed
interested in selling me an UltraBook, although they may have reconditioned
SparcBooks available later in the year (hopefully a bit cheaper too).
My final decision will be based on eventual use for a portable sparc, the
price, difficulty in obtaining replacement SCSI hard disks, the battery life
At the moment I'm leaning towards buying a small desktop Sparc like an IPX
or classic, putting in a large SCSI disk, extra RAM, getting a nice
aluminium case to carry it around in, and connect it to my Toshiba Libretto
as a console with X-Vision or something similar for any graphical work. It
may be a bit more bulky than a SparcBook or UltraBook, but it wins on cost
and availablility of replacement SCSI disk. A battery life of 60 minutes
for a SparcBook is too short for anything useful, so it doesn't really come
into consideration. If I happen to find a _really_ cheap SparcBook or if
Tadpole-RDI sell reconditioned ones with large hard disks for a good price,
I might reconsider.
Thank you all for your responses,
