A simple end-user tool would be highly appreciated too.

Re: Falcon Pal mobo and clock Patch owners

Well the remote debugging of this kind is very difficult, but have you checked all the connectivity between Falcon motherboard and CT60? That is where I would start. Over the age, all the pinheaders become oxidated. Moreover, if they were mechanically stressed, solder joints develop hair cracks (col...

Re: NetUSBee USB drivers download

I have built my NetUSBee today and took a time to test it with drivers from this thread. I was stunned how solid USB flashdrive support is. Finally, I have a nice and convenient way to tranfer files between Ataris and a Win world. Thank you! The USB mouse support works equaly as well, as far as I ca...

This is wher I get mine from:
https://www.ebay.co.uk/itm/1PC-For-Moto ... 3575053200
Its genuine rev. 6 as supposed to be, shipped fast and delivered in about 10 days. If it is used, as listed, then I have not found any marks of the use.

Re: ct60 with a pico psu - startup problematic

Another one in the mix: PicoPSU120 from https://www.cartft.com Unlike previous PicoPSU90, this one is pretty good looking PSU, both in terms of build quality and on scope. Except for one parameter: 5V is delayed from 3.3V by some 4ms. And surprise, surprise - this one makes Falcon/CT60 start and wor...

Re: Dead Falcon - no boot / coloured screen only

I second that, hot-air is the only sane option. Pre-heat the surrounding bottom area of the PCB (about 5x5cm, from bellow) to 230-250stC. Then pre-heat IC legs with a circular motion, top-down, same temperature. Quickly apply enough flux gel on all the legs and set the temperature to 380-400stC (yes...

Re: ct60 with a pico psu - startup problematic

ATX PSU specification says that Power Good signal has to switch from 0V to 5V not sooner as 100 ms after voltage is stable. To me this sounds as it is a good idea to connect the Power Good signal directly to the reset button or the reset signal. Does it make sense to try that? I wish it would be th...

Re: ct60 with a pico psu - startup problematic

Added third in the mix to my previous post here. As you can see Traco has both voltages at nominal levels virtually at the same time, the delta is around 0.1ms. Diametral ramps up 3.3V rail to nominal some 2ms before 5V rail does. ATX PSU has the time delta between the two about 3-4ms. Appearently i...

Re: ct60 with a pico psu - startup problematic

Yes, lower is 3.3V, upper is 5V. PWR_GOOD is not connected on/used by CT60 (shame, isnt it?). As for the C7 / reset line influence: I have already bigger capacity C7 soldered on, I guess its 22uF now. Thats why I can not repeat the tests with original (1uF ?) capacitor. Anyway, I do not see direct r...

Re: ct60 with a pico psu - startup problematic

Out of curiosity, I have made some real word testing on my CT60 (in 60 mode): It does NOT start from PicoPSU80 It does NOT start from brand new Traco power 60316 PSUs It does MOSTLY start from an old Diametral lab dual output power supply It ALWAYS starts from no-name 500W ATX PSU They all work well...

Re: ct60 with a pico psu - startup problematic

Seems like the 10uF on pin 14 (+5vsb) and 12 (-) of the 7474 is indeed not enough to stabelize and maybe 100uF might do the trick. (I now realize i named pin 14 and 12 pin 1 and 3 previously. This is wrong. The first and third pin for top-left are named 14 and 12) 7474 chips in DIL, SO(IC) and TSOP...

Re: ct60 with a pico psu - startup problematic

Another fix worth to try would be adding higher capacitance in parallel to C36, anything between 1-10uF.

Re: ct60 with a pico psu - startup problematic

There might be other reasons why 7474 keeps resetting. I have not had a time to scope it, but looking at the CT60 schematics, there is no AC filter cap on +5VSB (the always-on supply for 7474) and there is no decoupling cap on 7474 itself either, while I would expect typical 100nF ceramic cap tied t...

Re: ct60 with a pico psu - startup problematic

So maybe something can be put over r22 so it will not so easy change state? Indeed it looks as very likely scenario! I think I will pull out scope later on today :). Meanwhile, you could try adding 1-10uF polarized capacitor between IC8 pin 1 and ground, to see if it helps. Edit: It will only help ...

Re: ct60 with a pico psu - startup problematic

I have meant to say off-spec picoPSU is to blame, specifically slow ramp-up of 3.3 rail, but I do not want to start flamewar. But then I have realized it should be pretty easy to verify my thesis. If you want to do so: Disconnect a picoPSU from power brick. Short ps-on pin to ground pin using a shor...
