The Acorn NetStation is the box Acorn built to its own network computer reference design: a flat black desktop unit with an ARM7500FE, 8 MB of memory, NCOS in ROM, a smartcard slot and a plug-in network card, made to sit under a monitor or beside a television. Acorn sold it as the NetStation and the Home NC, and NetProducts sold a version for the NetChannel television Internet service.[2][3] For the range as a whole see Acorn Network Computer.

Versions

[edit | edit source]
NetStation versions
Version Network card Notes
Acorn NetStation TNS10 10BaseT Ethernet (Chris Whytehead's unit) Boots from a network server by BootP; Acorn's Home NC data sheet gives the TNS10 a 28.8 kbit/s modem[2][4]
Acorn NetStation TNS11 Listed by Chris Whytehead with 8 MB; details not recorded[2]
NetProducts NetStation (NS1) Acorn V34 modem rev 1 For NetChannel's Internet-on-TV service; IR handset RC1; SCART or monitor output; adapter PS1-UK[5][6]

Wikipedia says the NetStation came in a modem version for home use through a television and an Ethernet version for businesses and schools, both upgradable because the network card is a replaceable podule, and that the home version was trialled with BT in 1997 and 1998.[1] NetProducts was set up by Hermann Hauser in 1996 to make the NetChannel version; NetChannel's service was later closed.[5]

Chris Whytehead's TNS10 and NetProducts units both have the "NC 1 Main Board Reference Design", part 2103,000 issue 1, with a 40 MHz ARM7500FE whose built-in IOMD and VIDC20 serve as memory and video controllers, 8 MB of EDO memory on a module clocked at 16 MHz, and NCOS 1.06 in two ROMs.[2][5] Chris Whytehead describes the memory as a DIMM; Acorn's factsheet says a SIMM.[2][3] NCOS 1.06 reports itself as based on RISC OS 3.70.[2]

The network card plugs in at the back: an Acorn 10BaseT Ethernet adaptor (2303,600-04) in Chris Whytehead's TNS10, an Acorn V34 modem in the NetProducts unit. Acorn's factsheet also lists ISDN, ADSL and ATM25 cards.[2][5][3] Chris Whytehead's Ethernet card carries Microlynx Topcat in its ROM, which makes the NetStation boot from a Windows NT4 server; NetStations can also boot from an Iomega parallel-port Zip drive.[2]

Power

[edit | edit source]

The NetStation runs from an external mains adapter. Acorn's NC user guide gives the supply as 18 V AC from a 230 V adapter; NetProducts specifies its own adapter, part PS1-UK, for 220 to 240 V mains; the label in Acorn's photograph of the Corporate NC's rear panel reads 16 V AC 1.5 A.[7][6][8] Use the adapter that belongs to the unit. Both guides call for clear ventilation slots and a firm, level surface.[7][6]

Troubleshooting

[edit | edit source]
Symptoms and checks (NetProducts user guide appendix D, Acorn NC user guide p. 10)
Symptom Probable cause Action
No lights on the front panel No power Check the adapter is plugged in and switched on at the wall and plugged into the NetStation; check the fuse in the adapter plug; unplug the adapter from the NetStation for a few seconds and reconnect[6][7]
Continuous red light Standby Press the Standby button[6]
Screen red, front lights flashing alternately (long red, short green) Power-on self-test failure Remove and reconnect the adapter; Acorn says a unit that still fails needs expert attention[6][7]
Green light, no TV picture Phono or SCART lead, wrong AV channel Check the red, white and yellow phono plugs or the SCART plug and select the TV's AV channel[6]
Green light, no monitor picture, or a flickering unreadable picture Monitor lead; monitor not VGA or SVGA capable Check the lead and the monitor's settings; the NetStation needs a VGA or SVGA monitor[6]
Smartcard not recognised Card inserted wrongly Insert the card with the gold contacts facing down, contact end first[6]
No response to the IR handset Batteries; line of sight Check the three AAA batteries and the path to the front panel[6]
Modem shows "Dialing" but not "Connecting" within a minute Phone lead or line; pulse dialling or an outside-line code needed Check the lead and the line with a telephone; set Tone/Pulse and the outside-line code in the Modem screen of the administration utility[6]
"Looking for a boot server" repeats (Ethernet models) No server answering the BootP request Normal for a few attempts; otherwise the network server needs setting up[7]

Insert or remove a ROM card only with the adapter unplugged.[7] Take the batteries out of the IR handset if it will not be used for a long time, to avoid leakage damage.[6]

Chris Whytehead's photograph of an opened TNS10 shows the power input components at the front left of the main board, including electrolytic capacitors, a regulator on a small heatsink and a toroidal choke.[2] No circuit diagram or parts list for the 2103,000 board is among the hosted documents.
