Tektronix 1241 100MHz Color Logic Analyzer

. . . . The Tektronix 1241 enables hardware analysis up to 100Mhz sample with glitch triggering in autorun mode. This unit provides software analysis. 1240C01 - RS232C Comm Pack 12RS02 - 64K RAM Pack 1240D1--Channel 100 MHz Data Acquisition Card. The 1240/D2 18-Channel Data Acquisition Card is a 50MHz plug-in for the 1240 Logic Analyzer. Uses P6460 Data Acquisition Probes -------------------------------------- The 1241 Logic Analyzer is a portable color logic analyzer that offers up to 36 channels of hardware analysis and 72 channels of software analysis with acquisition speed to 50MHz synchronous and 100MHz asynchronous. With 14 levels of triggering and a dual hardware/software time base, integration is expedited. Fast friendly operation is assured with more than 50 soft keys (touch screen) for on screen menus and four operation levels. A nonvolatile storage memory stores two complete instrument setups. Utilizes various ROM packs, RAM packs and COMM packs for tailoring software control and acquiring data and control of communication interfaces such as RS-232 and IEEE-488.

Relatively easy to setup and use for a beginner, but they can go to "ridiculously complex" if you really want to. They have ROM cartridges that allow for mnemonic disassembly and state analysis of most processors. (Hmmm, I should probably make some "multigame" mnemonic cartridges since they're impossible to find for sale.) The 1240/1 also support serial ports, printer ports, etc. You can "program" the capture module to get the most use from the memory-- when doing video work recently I'd do things like have the Tek count occurrances on my "hblank" line (to get to a certain line on the screen), and then trigger and grab the data I wanted. You can do all sorts of "wait for this, then count this N times, then wait for this, then look for this, and then grab all the data" nesting and whatnot. If there's a weak point it's with the "capture pods". You need them 'cause there's circuitry onboard. They can be hard to find and expensive depending on where you buy from. And they have these little wire harnesses that plug into them too... The 1241 is basically a 1240 with a color display. (Well, kinda color. It's "RG" -- no "B".) You can configure them with different capture cards-- the most common configuration is probably a single 9-channel and an 18 channel card. Capture memory isn't very big-- only about 256/512 words depending on if glitch capture is on or not, but you can chain the memory from multiple capture cards to make longer traces. The 1240/1241 had all sorts of funky features-- like "teleservicing". You can remote control one from another by modem. Uses the RS232 port and 12RC02 "Master/Slave ROM Pack". there are a couple other features the 1241 has over the 1240, mainly just the fact that is can expand the timing diagram to fit the entire vertical screen height and that fact that its color, but thats about it. The RS-232 pack gives you the serial interface, but then you'll want the "printer support pack" to make it print to a serial printer. The Mnemonic packs have built-in support for the serial interface, so you can still do stuff like printing disassembly and state info without the printer pack. I used the "print" commands from the Z-80 Mnemonic pack to print to my old HP Omnibook running Telix when cracking Pacman Plus and The Glob (w/ Mike Balfour). Worked well.
