By that I mean using a PC and then transferring the programs to the 9100 for compilation etc. I do remember transferring a file backwards and forwards via the serial port by way of a test not long after I got the 9100 but I don't remember all the details. For instance whether this was possible for programs or whether it was literally just for text files. I also remember it being a bit clunky. Considerably more clunky than for the 9010. I appreciate the idea is that you do it all on the 9100. I don't know what it is about this, the clunky keyboard (yes, my PS/2 keyboard is pretty nasty), or whether it's the small amount of columns / rows that fit on the display but I tend to find myself doing the least possible to just quickly get out of that environment! It would feel so much better doing this stuff on the PC. Even if it has to be just in notepad. Any thoughts? Martin.

Message-ID: <4AF33240.1000709@flippers.com> Hi Folks! A handy tip for those of us with working tape drives...rotate the spindles of your tape drive at least once a month so you do not get flat spots!!! Even rebuilt tape drives will develop these after sitting for a year or so... Do this either by simply opening the lid and turn the spindles a bit - or read a tape. Also, repairing these. I found that a square VCR belt that is 3.1MM seems to work the best to replace the original drive belt. Replacement is not too difficult, remove the tape drive from the case. Cut off the old belt, then fit the new belt over the brass spindle and between the drive sprocket on the left by lifting the right side sprocket and moving the brass spindle to the right. Now with a dental probetha thas a hook on the end pull the belt below the deck and fit it into the slot on the brass drive wheel and over the motor and turn the spindle by hand until the belt drops into place. Put tape deck back. If anyone needs the belts I bought them from MainElectronics.com - about $4 for five belts. http://www.mainelectronics.com/belts.htm John :-#)# -- John's Jukes Ltd. 2343 Main St., Vancouver, BC, Canada V5T 3C9 Call (604)872-5757 or Fax 872-2010 (Pinballs, Jukes, VideoGames) www.flippers.com "Old pinballers never die, they just flip out" From matt at rossiters.com Thu Nov 12 16:00:14 2009 From: matt at rossiters.com (Matthew Rossiter) Date: Thu, 12 Nov 2009 13:00:14 -0800 Subject: [Techtoolslist] Logic Analyzer Message-ID: <4AFC775E.4050309@rossiters.com> Has anyone ever had a chance to look at this little logic analyzer? http://www.saleae.com/logic/features/ For the price and size, it could be a useful troubleshooting tool. I'm sure it can't do everything a tektronix can do, but a tektronix can't exactly fit in your toolbox or desk drawer either. I've probably mentioned this before, but I've been making a little collection of helpful videos including a video about the tektronix 1230 logic analyzer that really helped me a lot. http://games.rossiters.com/gallery2/v/tech/ Matt From trmatthe at gmail.com Thu Nov 12 16:55:21 2009 From: trmatthe at gmail.com (Tim Matthews) Date: Thu, 12 Nov 2009 21:55:21 +0000 Subject: [Techtoolslist] Logic Analyzer In-Reply-To: <4AFC775E.4050309@rossiters.com> References: <4AFC775E.4050309@rossiters.com> Message-ID: <1878be400911121355r4ae1e1b0obb94fe2fbdd15011@mail.gmail.com> 2009/11/12 Matthew Rossiter > Has anyone ever had a chance to look at this little logic analyzer? > > http://www.saleae.com/logic/features/ > Hi Matt, I looked into it when I was buying a replacement for my Rohde & Schwarz LAC64 last year. My main doubts about the Logic were the slow max sample rate, that it uses USB polling so possible to miss events (only 4x 512byte buffers on-board), and rather basic software. Looking at it again it appears they've bumped the sample rate somewhat and perhaps the software has improved. I also considered the Sigma http://tools.asix.net/dbg_sigma.htm which is a nice device. I was impressed by the sample depth as I had plans of snooping CPU busses, dumping the data through a disassembler and getting to the internals of some boards. In the end though I felt the software wasn't up to scratch. I finally ended up buying an Intronix http://www.pctestinstruments.com/ The software is amazing, it has a great sample rate, reasonable depth, 34 channels so enough for a CPU, RAM and intermediate logic, and real-time update. I really can't stress how good the software is. I have no hesitation in suggesting the Intronix as a starting point for anybody considering an LA. cheers, tim From c.cowgill at comcast.net Thu Nov 12 18:31:07 2009 From: c.cowgill at comcast.net (Clay Cowgill) Date: Thu, 12 Nov 2009 15:31:07 -0800 Subject: [Techtoolslist] Logic Analyzer In-Reply-To: <1878be400911121355r4ae1e1b0obb94fe2fbdd15011@mail.gmail.com> Message-ID: <35F89341AA2942C59F3E9858419A0970@ClayP4New> > > Has anyone ever had a chance to look at this little logic analyzer? > > > > http://www.saleae.com/logic/features/ > > I looked at it a bit-- 8 channels just seems way too limited and the price was kinda high. If you needed a really deep log of a slower speed serial bus or something it's interesting though. The USBee SX might be a better deal for less money (and has external trigger and clock channel inputs too). http://www.usbee.com/sx.html I bought a TechTools DV1-100 many years ago because I almost always need more channels than 8, but with just 18 it was kinda limited too. I never really got a warm fuzzy feeling about the hardware (I always seemed to have to fuss with it and get *every* ground connected to get things reliable, sometimes even then it seemed glitchy, etc.) and the software is pretty primative by modern standards. http://www.tech-tools.com/dv_main.htm I too finally ended up with the Intronix LA1034. I like that one. The 'pod' wires aren't as nice as the DigiView, but the software is much better and 34 channels is enough to do a lot of stuff. (ie, watch a whole 8 bit address/data bus and have a couple signals left for triggering events, or a 16 or 32 bit bus with a couple channels for chip select/write inputs, etc.) None of them even close to the triggering options on the old Tek 1240 family-- I miss that capability (when you only had 512 words of sample depth, you needed really good triggering!). In fact, compared to a 'real' logic analyzer I'd score every USB based LA I've used as "pathetic" when it comes to triggering. :-P If it wouldn't be such a huge PITA to setup (and the "hovercraft" level of sound it makes) I'd use the Tek1240 to do triggering and connect one of the USB ones up for the deep buffer. ;-) The USBee and Saleae units would be handy for a little portable protocol analyzer though. Stick it in the bag and be able to snoop I2C, SPI, serial busses where you don't need all the channels and the size is a plus. -Clay
