Sandra (et all), I also have a NTS-200 (on a remote site), which I'm eager to get fixed as the time on this unit is also affected by the week-rollover issue. I will pick this unit up for some debugging on this. Hopefully we can get this fixed, seems like a lot of people still have this unit... Ron |

I looks like you can use a AT49F1025 to replace the EPROMs on the NTS-200. They are pin compatible with 1 extra address line (A15) that on the AT27F516 is a NC pin. this will make testing code changes easier as the chip can be reflashed as needed unlike the 27F516 which is OTP |

if I'm lucky I finally found the NET+40 hardware reference manual and datasheet (more of a marketing sheet) see attached 73-NET-40-QIPRO-4.pdf (4343.89 kB - downloaded 114 times.) 93600.pdf (175.72 kB - downloaded 97 times.) |

Just noticed this, from my original post my nts-200 is now toast. its weird, its rollover occured very early january I think or something. My machines started saying it was 2006 :/ I guess these things are basically paperweights now... shame. |
