It gets more complicated, though. We have a lab full of Tek logic analyzers (about 10yo if I recall). They had a retail value of about $11K each I think, although we got a discount. We discovered after we bought them that they ran on Windows 2000. Last year we persuaded Tek to give us the drivers that would work on XP, and upgraded the LA's to XP. Don't know how many more times we can make that happen. I have a couple of 20yo Philips LA's that still run, but they boot off a 3.5" floppy, which is an iffy device after this many years. No idea of what OS (if any) those are based on. I discovered while getting ethernet networking going with our new Fluke 8846 bench dmm's that they are running some version of Linux. No provision for any sort of updating/upgrading on those (without significant hacking anyway).
We have to be careful how we build LinuxCNC machines to avoid giving future users the same sorts of problems. I'm glad the system is headed in the direction of packages that can be added to standard distributions rather than relying on installing from LiveCD's, as I think it makes it easier to build in anti-obsolescence. -- Ralph ________________________________________ From: John Dammeyer [jo...@autoartisans.com] Sent: Wednesday, October 08, 2014 9:06 AM To: 'Enhanced Machine Controller (EMC)' Subject: Re: [Emc-users] Oscilloscope + logic analyzer (PC based) I own an EPROM/PAL programmer that runs off the parallel port. At the time to get the PAL feature I paid a significant amount for it. The shift from Windows 3.11 to Win95 orphaned the product two months after I bought it. I kept a WIN3.11 system around for a few years but doesn't matter anymore because I don't use EPROMs nor those PALs. I also own a 32 channel logic analyzer pod that runs off the parallel port. Last time I was using it was WIN-98 or maybe XP. I wrote custom DLL code for it to do CAN bus decoding from the bit stream back in 2001. I haven't tried it with WIN-7. Don't know if it will work. None of these products were supported under Linux. Doesn't matter as much as I now have a stand alone 4 channel Tek Scope with a 16 channel logic analyzer that also does SPI/IIC/CAN bus decoding. Although companies are full of the wildest dreams of staying in business forever (or in the case of AlibreCAM being purchased generating a ROI) the truth is supporting old hardware is really expensive. We live in a throw away world and that logic analyzer/scope that works today on WIN-7 may not work on WIN-9. And when your WIN-7 hardware fails the license for that scope module which was keyed to the CPU no longer works and the company that sold the scope no longer supplies upgrades for WIN 9.00100. The problem is test equipment sometimes sits there for months not being needed. It's like the bandsaw in the shop. If you don't build anything for a few months that requires that tool it sits idle in the corner with a dusting of sawdust on it. But when you need it you walk over to it and turn it on and it works. I do that with my Delta Saw built in 1935. I can also do that with my 30MHz Gould Scope that I bought in 1978 although I suspect I'd probably have to replace some filter capacitors. Not a problem since the user manual came with Service Information and Schematics. Just an observation that these little pocket scopes and logic analyzers have a very short lifetime.
