Thandar LA160B ROM download-Where from?
« on: May 26, 2023, 11:11:42 am »
I've just bought a Thurlby LA160B Logic Analyser, and I'd like to download the EPROM firmware (including the LR-64 option ROM) so that I can have a backup. Does anyone know where I can download the firmware from? Thanks.

David.


PS I will need to make a backup of the EXISTING ROMS in the instrument when I receive it. So I also need to make/buy a simple EPROM reader/programmer. Does anyone have any suggestions for one that supports the EPROM used in the LA160B? This is all a bit of a whim based on finding around 6 off LA160 PODS that don't have an actual LA160 to connect to. So I've bought myself one in the hope that it will be useful/educational.

Hi David,

still interested in the EPROM contents? I can provide you with the i.e. BIN-files (version 5.0: LA160-50 and LR64-50) if you want them. Well, actually they are out of my IE1620, but they are exactly the same.

Talking about unused (data) pods: I will have soon two of these analyzers but just a single pod with the variable threshold level (IE1620-1, which is, if I'm not mistaken, the same as the LC-02). Maybe I can buy the one I don't have from you?

Currently I'm still in progress with a complete reverse engineering of that analyzer and that means redrawing the PCBs and schematics. If you're interested in receiving those files just let me know.

Greetings

Raimund

Raimund,
Yes, I'm interested in ANY firmware you have for these, thanks. I recently bought an Interplex IE-1620 from the states. Problem is, it only works at 110v, so I have to use it with an external autotransformer or figure out a way to drop 240v to 110v internally. I don't have any LC-02 pods. The only ones I have are LC-01's. I would be interested in details of your reverse engineering, including any schematics and PCB layouts. Especially if they are done using KiCad. Thanks

Hi Raimund,
I have a Thurlby LA-160B. I would be extremely interested in a copy of the LR-64 50 if you could possibly send me a copy?
There is a site https://sonicsheep.com/Electronics/2-Thurlby%20LA160.html that has details of the pods, so you can make your own.
Regards
Alan.
