I bought a Atari 800 XL. Did I do good?

[I bought a Atari 800 XL. Did I do good?]

Really depends on the shape it is in and if it came with original box and/or manuals, etc. Post pics?!

[What did you buy today?.........]

New in box Compumate matched up with my composite mod Vader. Match made in heaven...

[ATARI CX-22 Trak Ball replacement encoder wheels? Anywhere?]

If you got a good one, could it be scanned and printed? Someone in your area probably has some good equipment and can do this. I'm just dipping my toe in the 3d scanning / printing world, but already see some amazing potential.

I thought about this already as well. The other one is non broken, so it could be done. Not sure.

[ATARI CX-22 Trak Ball replacement encoder wheels? Anywhere?]

Might just modify one with a HAPP joystick, low profile arcade button on right and a steering pot on left. Hmm...

Haven't seen that done before.

[ATARI CX-22 Trak Ball replacement encoder wheels? Anywhere?]

Over past 3 months I've acquired three CX-22's.

- One of them works flawlessly.

- One of them has warped clip on encoder wheels (C020571 Rev 3) causing jittering and malfunctioning movement.

- One of them has warped press on encoder wheels (C020571 Rev 5) causing jittering and malfunctioning movement.

 

I contacted Bradley at Best and he no longer has any replacements, but gave me the hack tip of heating them with hair dryer, etc. Here is the issue, I accidentally broke one of the press on wheels last night while dis-assembling.

Anyone know where I can get replacement encoder wheels? Anywhere? Leads?

 

Would love to get all three working. Well, the other two since one is working.

[NOS Atari 130XE - Not working, Need Help!]

Have you tried the RF out using a RF to COAX adapter to see if it works that way? Would be a start. also, if your cable is not proper, the plug colors will be different as SignGuy81 suggests.

 

I have a generic DIN to RCA (Y/B/R/W) that definitely does not match color wise to what I would expect. Yellow is Composite Video and Black is Audio. Red and white are not used.

 

I also have a Best Electronics DIN to RCA (Y/R/W) and the colors are correct. As they should be.

[RAM upgrades]

I have recently bought one of the old wizztronics upgrade boards, (pre Best Electronics) it has a 7-wire ribbon cable whereas the Best version needs only 6 wires, does anyone know where I could find instructions for the OLD wizztronics installation?

[How much should I be paying for Atari 'Pro-Line' Controllers?]

I mean these:

 

 

Basically, I remember using these on my Atari 2600 Jr. and I liked how they felt to me. (I understand they probably weren't meant for the Jr, but the 7800, but still!) But ebay seems to want like... 59.99 for a set?

That seems realllllly steep. Is that correct?

These were packaged with new junior's overseas, so they were marketed for both units, just not in the US

[The mT RAM investigation thread. Show yours, good or bad....]

Found this nice pic of a set of (defective ?) mT's in another thread here...

 

They're from NISMOPC's 65XE. They're all datacoded 447

 

I hope he will comment here if some or all of these were defective.

2 chips were defective. Can't recall which two though.

 

I've fixed a few 65XE's and seems like most of them have 1 or 2 bad. One unit I put all NOS TI chips in. The others, I just replaced the bad one's with good mT chips from the unit that got all NOS TI chips.

 

ALL of the units got socketed

[Best source for Atari 8-bit ram chips?]

Have you ever put them in an Atari 8-bit computer? If so, did they work?

Yup! Saved a few 65XE's with these. No reason they shouldn't...

[NEW CX-77 Atari Touch Tablets at BEST]

Rcvd one in a huge lot I purchased off ebay a few months ago. Is in great shape and even came with AtariArtist cartridge.

 

Worked perfectly but the protective cover saw better days.

 

Best Electronics also sells replacement protective sleeves!! Bought one from Brad.

[Odd collection of roms with a 2600 in a Sears Case]

My guess is a previous owner had a ROM burner and borrowed all his friends cartridges to burn his own collection. Just a complete assumption on my part, but $5k is freaking ridiculous!

[Will Texas Instruments TMS4164-15NL work on an XL/XE?]

I tried them on an Intec 48K board for a 400 and had no luck. They replaced some MT4264s. I could not get the 400 to show anything, just black screen. Any ideas on why TMS4164-15NL wouldn't work in this application?

Found this on another thread regarding what you did:

 

- 4264 is 65Kbit all right, but organized as 4x16K, not 1x64K like the 4164

- 4264 is backward compatible with the 4164 but the 4164 is not upward compatible.

 

That would be why it did not work.

[Will Texas Instruments TMS4164-15NL work on an XL/XE?]

I've used those on 65XE's with great success. Bought them on ebay NOS.

 

Here is one of the units I fixed replacing the mT units with sockets and TI chips....

 

Original non-socketed mT DRAM

 

NOS socketed TI RAM

 

[Can you name this 400 replacement keyboard]

Going to quote some descriptive select words from the masses...

 

Well, love it or hate it, this beautifully hideous, heinous, awkward, ugly and big unit SOLD. All packaged up with layers of bubble wrap, snuggled in a blanket of popcorn, encased by a wall of styrofoam. It'll be on it's way to it's new owner tomorrow.

 

Somewhat sad in a way to see it go, especially with the time spent on it and the mods, but I'm a ATARI collecting hobbyist who keeps what he wants, sells what he doesn't, and am ready for the next project(s).

 

I've got "more fish to fry" or is it More Atari's to Save!?!?!

[Nathan's WTB/WTTF List. (Updated 1/20)]

Try GameStop online. They have deals with their premium refurb's and they come with 2 games as well as a wii controller. Cheaper than just the refurb'd units they sell in-store.

[sio2sd on atari 400]

Not that this helps you, but I am in the process of selling a 400 w/64K Mosaic RAM upgrade. (ebay)

 

When I was testing it's functionality, I hooked up my SIO2PC and it worked just fine. Had no issues.
