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]| 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]
Hardware
[edit | edit source]
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]
| Position | Item |
|---|---|
| Front | On/Standby switch; smartcard slot; infra-red window; power and activity lights; ROM card slot behind the flap[2][7] |
| Rear (NetProducts unit, left to right) | Modem card; printer port; PS/2 mouse and keyboard; left and right audio out; microphone; TV/video out; VGA monitor; power in[5] |

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]| 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. For general capacitor failure signs see Capacitor Failure Symptoms.
