I wanted to follow-up on my first message with more information in the hopes
someone can help.
I have been having problems with downloading to my RCX. I started trying NQC on
a mac and this did not work. I then ported NQC to Solaris and had some initial
success, but there were still some problems (see below). I then borrowed a
friends RCX in an attempt to see if was my RCX or the setup, and his RCX
worked fine with my mac and NQC. His RCX did not work with NQC and my solaris
port.
I then tried my RCX with his PC and the Mindstorm software and everything worked
fine!
Both of our RCXs were purchased in the past two months, but there are some
differences. I was wondering if this could account for the problem. His
RCS has "RCX 1.0" on one side, and a six digit serial number starting with "1"
on the other side. Also, his has a connector which looks like an AC adaptor.
This is on the side below the motor outputs.
My RCX has "RCX 1.0" on one side and the serial number "455036" on the other.
Also, I have no AC adaptor connector. Both RCXs came with a Mindstorm 1.5 kit.
Has there been a design change introduced recently in the RCX? If so, the new
Mindstorm firmware would recognize both the old and new versions, and the third
party software might not. This would account for the symptoms.
Also, I have tried Kekoa Proudfoot's "send" and "firmdl" programs. The "send"
program seems to work with my RCX and the "firmdl" program does not. Here is
the output I get when I try to download firmware to my RCX using "firmdl".

Thanks for any help you can offer!

| (...) Offhand, I'd suspect that the problem is either interference from lighting in the room, or perhaps your IR tower is 'marginal'. From your tests so far it doesn't sound like the problem follows either a specific computer or an RCX. Minimize the (...) (25 years ago, 2-Feb-00, to lugnet.robotics.rcx.nqc)
