RCA NC1020 set top box

Unread postby zahal » Thu May 31, 2012 9:19 am

Picked up a RCA "network computer" NC1020 set top box.
Oogled around and specs on this machine are:
ARM 7500FE processor. 5MB RAM, 8MB ROM.
VGA, S-Video, RCA video out, RCA audio out, Parallel port, PS/2 keyboard and mouse ports (and also has frontal IR for wireless keyboard/mouse). Also has a PCMCIA port up front and a smart card reader.
Opened up the gadget and RAM is soldered (no slots). Might be able to remove the chips and put higher density chips (or piggyback chips on top of existing ones) to increase RAM.
However, upon connecting VGA monitor, I get signal and a line reading "Acorn ResourceFS", then a screen with a centered cursor, and a rotating sand clock. Then the screen goes black.
Finding manuals/software/OS upgrades for this thing has proven a still unfinished task.
Not much remains online, lots of broken links.
Found a very good document that covers all sorts of network computers. Too bad it's in finnish:

If anyone has played with this box before, I'd appreciate any assistance.

Seems it had a limited success back in 97-98 (arount Apple's Pippin time, which is also covered in the document linked above).
As the real AppleTV (version 1 and 2 seem to have been experiments) is about to be lauched (or at least unveiled) at WWDC next month, seems like a good time to recap on the road to Apple's next iAdget.
Sitting in a room.....thinkin' shit up. :evil:

If you can see "Acorn ResourceFS", what you have is probably trying to boot NCOS, a variant of Acorn's RISC OS for thin clients and set top boxes. It is possible, with a parallel port Zip drive and a prepared disk to boot into a desktop. Known as a Netstation, but the same basic hardware was OEM'ed under several names. Try:

Firmware version info on 4 different NCOS incarnations at http://www.chiark.greenend.org.uk/~theo ... smods.html

Good luck!
