1450 XLD motherboard build, assorted questions

To test the speech, just boot with option down. I believe it will read you the menu screen "Atari self test. Press start select or reset"

 

Congratulations on building such a wonderful machine!

Nope, the self-test doesn't talk on mine. I found something else that does though :)

 

First Keyboard test: SUCCESS!

First Speech test: SUCCESS!

First Modem test: SUCCESS!

 

As far as I can tell so far EVERYTHING works, and on the first try!!!!

 

I've been waiting for this for 30 years.

 

enjoy:

Good job. :thumbsup:

Do you have the schematics corrected and a parts list with sources?

Which modem did you use?

 

If someone else has the bare boards maybe we can get together with a large parts order and reduce costs.

 

Awesome!

 

 

Looks like it's turning out better than Johnny Cash's

, ha.

Since you are planning on building another one, did you buy double the parts or will you be ordering again? If you will be ordering parts, I'd like to get in on it if we can lower the cost by doing so. I have a few main chips and sockets, but didn't do much else yet.

I bought doubles on many of the parts that I thought might be hard to get. Quadrupled on some like the modem, I bought (2) of the TI modems and (2) of the National modems since I didn't know what would work. It turns out that there is another error in the schematic, and if the board is jumpered for the TI modem as called-out, you will likely burn something out. I didn't double up on the common stuff like resistors, caps, etc.

 

cheers,

If there is really that kind of demand, we can make more PC Boards

 

I knew I'd end up kicking myself in the butt for not buying a 1450 board when they went up...

Anyone got a spare ?

 

BTW, excellent job on that build :)

Demand +1!

 

I have wanted that system since it was shown in the catalog.

 

 

PS: It was great to hear the Atari's specific "Voice"! So that's what it sounded like! Very nice! Blends perfectly with the other Atari sounds in the video. Can we have some more speech demos? Thanks!

Absolutely, I would be in for a 1450 board! Let me know what the expected cost for a bare board would be. :thumbsup:

UTTERLY F-SICK (!!!)

 

This is not supposed to be happening, or even possible... :)

 

The results of this project seem to openly defy not just fundamental macro-economical principles, but they also represent an anomaly, a singularity in space and time.

 

This machine was able to travel forward in time, for almost three decades, with garbled technical documentation, no real parts on it, with no hope of seeing one single electron flowing ever again accross those circuit-tracks... yet, somehow, it came back to life...

 

Congratulations for your determination and absolute resolve. Well earned and deserved.

How about that and a new bottom case plastic for the 1200XL to take the 1400XL motherboard?

 

Yeah, I'd sign up for at least one of those, and probably more.

 

That sounds like a good idea. I'd be interested.
