Looking for CT60/63

Anyone have a spare one? Eventually, it could be a faulty unit as well.
Please PM me.

Re: Falcon crashing when moved

Yes, large ICs could be the cause, as mikro says.

Re: Faulty Atari 520STe - black screen

I have spare set of original 1.62 I can give you, provided that you cover postage from Czech rep. I am not sure what language they are, prolly DE, but that should not matter for debugging.

Re: Dead Falcon resuscitation

Nah, I am not selling that one. Nope. Nada. I have made that mistake some five years ago, so what I am undertaking here is kind of redemption for me. I am not going to be that stupid again. But maybe, there will be flood of Falcons NG one day ;) Meanwhile, I got analog audio up. Boy, that keyboard t...

Re: Dead Falcon resuscitation

I guess I will put a new DSP, mic, spk connectors and remaining (audio circuity) caps back on and see where we got from there today :)
See that is a precious victory. I am genuinely happy.

Another tough fight today, but guess what - there is no doubt who is the winner of the day! Yes, the mighty Phoenix has arised from ashes :) Still got some wings broken, namely serial and entire sound subsystem, but its gonna be piece of cake from now on :)

Re: Falcon crashing when moved

Oh and you might wanna try wiggle all ferrite beads, they were hand soldered, mostly sloppy job. There could be one with cold solder joint.

Re: Falcon crashing when moved

Try heating up running board part by part with reasonably set heat gun (150stC) to see if you can isolate the problematic part.

Re: Beginning of very long journey

Good question, the compatibility with existing CT6X is one of my goals. Either way, what mikro suggest is very interesting piece of hardware, based on RTL chip driven by Altera CPLD. I would like to have this postponed for next revision, where I hope to implement large enough FPGA, which should the ...

Re: Beginning of very long journey

For this revision, the only solution is to disable XROM3 and XROM4 signals routes to both chips via on-board jumper, whenever you want to use ROM port cartridge. There is also unused serial interface in MFP, that could potentially used to manage whole lot of additional devices and that could be SW d...

Re: Beginning of very long journey

Shoot. I have realized they are harder to obtain, but I have not expect the situation to be that bad. Do you have an experience with, or have you considered ISP1161? They are more recent than 1160.

Re: Beginning of very long journey

LAN and USB are basically on-board NetUSBee implementation, so current drivers should work out of the box.
USB: Phillips ISP1160
LAN: Realtek RTL8019AS

Re: Beginning of very long journey

all sounds good, you sound like you know what your doing :) Only time will show. And while debugging that dreaded Falcon board board, I have also quite progressed on F030NG. Schematics, except for DSP and analog audio are now complete, LAN and USB are in place. I have also did a first version of bo...

Re: Dead Falcon resuscitation

Thats right. Bloody musicians, they just dont care about their equipment. At all. Just like my brother, in average he used to kill 3 keyboards a year. They all mostly died because of spilled beer, from beeing stepped on... and of course by a cables that have AC where they should not.

Re: Dead Falcon resuscitation

So this led me to check some more components, namely few logic ICs and... I got a CPU, COMBEL and VIDEL alive!
Keyboard, sound, serial port, 1772... none of it is working (yet), but I believe this a very good start :)
I will check few more ICs later, but this time I think it's down to MFP.

Re: Dead Falcon resuscitation

Its probably time to admit I have started to suffer from dementia and some form of blidness too. When I was first looking for any traces of what could actually be the root cause of all the multiple failures this board has, I did thorough inspection of it. First I gave it a bath in IPA and when it's ...

I think I will do a Combel blind-swap and see if it help. I can not think of anything else now.

Re: Beginning of very long journey

By twe way looking at the DSP memory bus schematic I am confused by the way highest adress line (A14) is handled. Its not only connected to corresponding memory chip pins, but also interfaced by DSP_XY signal from DSP pin 43, through U39 gate. Falcon service manual says: "This signal is used to...

Re: Beginning of very long journey

So faster DSP is no issue (mikro), but larger memory on DSP bus is, unless it is patched in (Emu)TOS (Otto)?
