TLA7xxx hacks (32M Depth on TLA7AA4CS enabled successful) :)

Thanks gslick, I look forward to trying it.

For completeness, this also appears to work the same way with TLA7Lx and TLA7Mx analyzer modules, with the exception that with firmware version 3.2.1 that password is in all uppercase, i.e. "PITBULL3.2.1". And of course the maximum sample depth value choices are smaller.

Here are the actual commands that I used to update a TLA7M3 from 100MHz State to 200MHz State.

(write) and (read) are not included the command and response text sent to and from the analyzer module. The unix timestamp of 1424217600 corresponds to 02/18/2015 @ 12:00am (UTC).

 I'll give this a go on my TLA7AA s this weekend. One of them has max speed, but small depth, the other has max depth, low speed ::). However, I have one two question(s) about the procedure; where you have
 
       Set Parameters
       Code:
 and
       Save Parameters
       Code:
 
 what is the parameter? Is it a drop-down box with pre-defined values, or ...???
 
 When you entered 1404025200 as the timestamp, did you have the true (e.g. today's) date set on the TLA, or had you changed the TLA Windows date to, or near to, 6/29/2014?
 
 Thanks,
 Sailor

Hi Sailor,
 
 Hi there GSlick,
 
 I just copied the commands verbatim just as dxl & kk worked things out. The process did not error out. My TLA7AA4 CS upgraded to ES and the modules remember their settings through power-cycles. In other words, I copied and entered the lines exactly; its true, intuitively one considers that there is some type of 'list' expected, but no, just enter the commands verbatim and click the WRITE button.
 
       Set Parameters<click WRITE>
       Code: <click WRITE>
 and
       Save Parameters<click WRITE>
       Code: <click WRITE>
 
 Re; the 'time-stamp' data, yes, I just used kk's value, and no, I did not change the analyzer's CMOS time or the OS time.  I looked around for a way to generate a 'current' Unix Time-Stamp, but couldn't figure it out, so I just tried kk's TIME-STAMP value and it worked just fine.
 
 Let us know how things go...
 
 Cheers,

Yeah, I have this thread marked for when I can find some free time to do the same with one of my TLA704's (I have two).  I wasn't even aware it was possible to use the 7AA4 modules with it, before I read it here.   :-+  Very good stuff, and thanks to all.

Hi MarkO,

The TLA704 hack takes a bit of work, and there is no direct pre-worked-out strategy for some of it.  One area is the LCD issue. To run Win2k requires a memory upgrade BIOS flash operation (one TLA-704 motherboard bricked and two others worked just fine), in addition to that, there is an additional BIOS hot-patch hack required (ROM image provided by Mr. Green) to be able to run the LCD at the minimum of 800x600 resolution required by Win2k. An external monitor can be used, but frankly doing so takes lot of bench space.  The native TLA704 LCD only runs 640x480 so it must be replaced with something. I very luckily found a new 10" NEC LCD, that was mechanically a virtual a drop-in replacement (only had to cut out a slot), and I had to fabricate a new interface PCB (Eagle 5.5) and find connectors for it, all were available only as SMDs. As I did not have any reliable strategy for cooking SMD parts, I hacked together an SMD oven (that's a whole 'nother story, one that I'll share should anyone care to hear it? I have complete plans that work well, uses a PIC uControler.) 

For me, upgrading my TLA704  was a multi-year adventure. Although I do have all the linkages, it'll still require some cutting, hacking, solder'n, copying, pasting...and sweating.  But frankly it was very rewarding and it works great when run remotely via EtherNet!!  I love it now and with the 32 Mb TLA7AA4, its hot!

Wow, that's lot of pain to go thru.
Would make up a great article about, how to get desire come true :D
I could host and provide storage for files endlessly for stuff like this
