SINGLE TOOTH

I've had great success. I've managed to dial up to a BBS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I had to use the Modem cable to the wimodem232 and use the right SIO port on the "old" 850. It really sucks that the old 850 has a bum sio port and the NIB 850 doesn't seem to work. I did get it to make that distorted fart-like noise a few times where it should be loading the drivers. I reseated all of the chips on both 850s and no change. Although I think I did manage to break the socket somewhat on the new 850. I didn't realize it was some sort of ZIF socket that slides. I'll try the multimeter continuity advise as previously suggested... Any other tips on how to get these 850s working?

How did you fix the power switch? Resolder it?

Sweet! I like the TI99 setup too. I saw the little Professor calculator on your shelf, lol. I used to have one of those as a child. I like the Atari Setup, that's pretty awesome. I really like seeing people's setups. You use ICE-T with your wimodem232? I also like the litte atari badge on your monitor, that's a nice touch.

I see a small pic of your setup in your avatar photo. Got any larger pictures? I'd like to see your setup, it seems pretty sweet.

I actually purchased both. All kinds of people were telling me to use the "null" modem cable aka the Terminal Cable. I didn't understand why that would be needed so I bought the Modem cable also. I'll try again with the Modem cable.

I did get to this point before, but now I understand more what is happening. I have been cycling through the baud rates, and get no response. I stupidly got rid of my actual Hayes modem. I don't have any other serial modems, only the XM301 sio modem. I will hook the wimodem232 back up to my compaq and make settings.

When I have the computer in this configuration, the device information programs still do not see the R: device handler. Also, I am not using custom cabling, I purchased the actual Terminal cable from atari.

I don't really have an answer to why... You're right, there is no real reason do to this. Just curious IF it is remotely possible.

Theoretical question: I wonder if the circuitry for the keyboard input is there? (IC's and such) Obviously the keyboard port/connection isn't and something would have to be soldered in. I wonder if you could somehow get a keyboard working with the hardware. I assume the BIOS would need to be modified to support it.

I tried this after and still cannot access the wimodem232. I hooked the Atari up to the 1050 then the 1050 to the right SIO port on the old 850. Nothing in terminal. I can now understand when Chameleon terminal program loads the driver for the 850, I can hear it after you select option 2. BOBterm also makes that high pitched noise and changes pitch when you change baud rate. Still unable to access the wimodem232 via terminal. When I'm in full duplex mode, the terminal doesn't seem to input the characters I type. When I do into half-duplex I can enter characters, but never get any feedback from the wimodem. Not sure why I'm having such a hard time with this. It probably doesn't help that I'm a complete n00b with Atari 8bit and have faulty ports. I tried ICE-T, but can't figure out what to put when it asks me to set device.

Do programs have to be written in assembly or a certain language to be converted to 5200? I know there is no basic rom in the 5200 so basic programs wouldn't work. (hmmm, what about the basic cartridge?) What about PILOT or the other languages?

I think I got somewhere with this tip The old 850: I can not get it to do the special beep in the left SIO port when booting. I only hear the beep when I boot with the SIO cable in the right port. The new 850: I cannot get the beep in either SIO port. Once in a while I will hear a short fuzz noise when booting. That’s not normal and I don’t know what that means. Otherwise I get the generic beeping from the computer as if nothing was plugged in.

Ive swapped everything. Swapped my 130xe for my 800xl Swapped 1050s Swapped 850s Swapped cables Swapped power supplies for the 850 Still no R: handler

Theres no R device on either 850

Someone else just posted about the same thing with no sound in demo mode. Personally, I would go with the Best option. I bought the parts and rebuilt mine last year and haven't had a problem since. Hopefully it lasts.

Do you have controllers that you can actually start a game and get it out of demo mode?

Probably exactly what happened,

I should mention that I've used my wimodem232 on my Compaq LTE 5000 and configured it months ago. I can't remember what I put the baud rate at but I'm sure I didn't go above 9600. I had previously cycled through all the baud rates in BobTerm and none worked.

What's strange is with the old 850, bobterm does not report any error, I just can't seem to get a terminal response back from the wimodem232. With the "new" (new in box) 850 bobterm says there's no modem handler at all. This is with the same bobterm disk. Does it matter if I'm using a 1050 drive? Can only an 810 be used? I should be able to use a "happy 1050" drive with the 850, right? Installing a happy mod is the only difference since getting the new 850. I should hook the old 850 up again and see what happens.

I really like the Sears variants. After that, I'd say the normal picture label.

Yup that's normal. at least both of my drives do that. I find it satisfying to insert a disk lol.

So, I've still not gotten anywhere. I ordered a New Old Stock 850 that was sealed in the box. I opened 'er up and plugged it in, but Bobterm tells me there's no modem handler, and Chamleon says there's no device when I try option 1 or 2 (using an 850 with generic or Hayes modem). Ugh.... I'm stumped. But with this 850 I can plug the disk drive into it and the drive will boot unlike the old 850. Cable swapping didn't help. Tried both the Terminal and the modem cables in serial port 1 and nada.

Probably hard to find a power supply with the requirements these drives need just laying around anymore these days. Might have to order one. 9V AC 31VA

How hard was it to desolder the chips? I've heard these boards suck to work on since they are cheap.

The next drive I bought was smashed up too, but a seller that didn't know how to pack. Luckily i was able to fix them both and they still worked. Before After
