I think you should also post a link in the eevblog repair thread on the 2465 when it's finished. This will be a really great tool. I have a 2465B sitting in my queue waiting for me to get around to

Only because I have been there and done that too many times. I first started with the 6800 as a kid and I actually have XC6800 versions of the silicon in my collection, which were the preproduction

Hi Chris, I knew you would understand. And, thank you for doing this. I could, but, the first Motorola processor I wrote for was the 68020, which was a lot different from the 6808, and fundamentally

Hi Chuck, Yup. Totally get it. I only mentioned S-records because that's what you get out of the assembler along with the listing in hex. I'll also convert to your "blob" format, which is just a hex

Hi Chris, The EPROMS are fully decoded. U2260 goes from 0xc000 to 0xffff. NMI is generated when the power switch is turned off. It should be perfectly ok to drop into a halt or loop. No status

Dan I may look into this as i seen on the EEvblog. Looks promising. Conversion of 500MHz TDS744A to 1GHz TDS784A - Page 1 (eevblog.com) (

WHEN you repair it… search the forums for how to convert it to a 754 or other higher functioning / bandwidth version! I did this to mine, and I did document all of the jumper settings so search for

Radu Thank you for the Kind Words and encouragement to continue on. I have found the 520m and a copy of the 544 which seem to be a close match too. I had many problems so far, but I believe I am

Hi Guys, Give me a few days to research and dig into this-- $DAYJOB in the way for now but I will do as soon as I can. The program is very simple. I just need to confirm execution address and a little

Mike, I'm working on a TDS 754D with acquisition board issues - which I hope are related to the SRAM, not the input stages, which, as Dan describes, I think are more challenging to work on - but one

Dan Thank you for your thoughts and recommendations about using the other group. I have posted this same question there, hopefully it will get a bit more people's attention. At work at the moment but

There is a group called "TekScopes" that has more traffic, you might want to post there as well. I owned a TDS744A that came to me with analog input issues. Mine did have a blown input module, but

Ok, here's the drill. I think the best/easiest way for Don to get his codes back into his 2467B's pre 50K battery backed RAM would be to burn a little code snippet into a 27128 EPROM, and run it. The

Hi Chris, 256 words, or 512 bytes (0x1e00 to 0x1fff) are always set aside for the calibration data. There are only actually something like 170 16 bit words. The 2465(no suffix letter) used an EAROM

Absolutely agree. I just figured for the OPs goal, it might be a long slog to get Linux up and running before he ever got to the task at hand, assembling some 68xx code. I didn't want him to believe

I have an TDS744A That has Had many Different Problems. I have Gotten it down to the Acquisition board and Attenuators. I am look for some advice on what to do next, as there are no schematics that

Hi Chris, It really doesn't matter where you do your development. I choose linux. I stopped using MS products in the 1990's, after paying a ton of money for support on an MS development package. Their

Reinhard, I agree that re-calibrating the scope is the best option in this situation. However, I do not have the equipment to perform the calibration correctly, and I cannot justify the expense of

Chris, Thanks for the links to the windows versions of the assembler. I will try to find the memory map of the scope and will l

I run from any digital scope, I don't want to deal with the drama of finding parts and softwares. HOWEVER- there is a (transgender) gal on YouTube who is quite amazing in her abilities to restore
