I tried it out after verifying the voltages were all good.  The drive will spin for a couple seconds after I power it up, as expected. But when I try to access the drive, nothing happens and I get a 138 - Device Timeout.  It seems that the control board isn't communicating with my Atari.

Are you sure it's set as d1:? Have you tried booting from a different drive and see if it responds as a different drive number?

Did you try adjusting the color pot?

I just found out that you can easily use a 2764 to replace a 2732 by duplicating the 4KB data into the upper bank. Then connect pins 1,2,26,27 & 28 together and orientate into the socket with pin 3 to pin 1 of the socket and the corresponding pin 26 to the socket pin 24 which is VCC 5V. All the other pins then line up with the correct signals. You do need enough room for the overhang but I just tried it successfully with a US Doubler.

 

I've always liked this diagram that shows just how pin compatible all of the 27xxx EPROMs are: 

 

 

 

[Indus GT with CPM Chip - Rarity?]

I bought an Indus Drive with the original board in it years ago. It's the only one I've ever seen or heard of, so I would say they were fairly rare.

[Need Atari Indus Disk Drive Help!]

Are you sure there aren't just a couple of segments of the 7-segment display not illuminating?

[What was your first experience in computer programmimg?]

1978 using a teletype much like this one to write BASIC programs on some unknown mini computer at college.  Followed shortly by IBM 370 coding in FORTRAN and ASSEMBLER.

 

[Help ID Mods to 800 - Omnimon and ??]

Yeah, I don't see anywhere for Omniview to reside on that board. How does the system act when set to view?

 

[Help ID Mods to 800 - Omnimon and ??]

It looks like you have the Omnimon 8k ( https://archive.org/details/NewellIndustries8KOmnimonManual ) Upper and lower will be mostly similar but certain commands are only available in one bank or the other.

 

To see if you have Omniview set the switches to Newell, ON, View, and boot into basic type X=USR(49152)  and you should get 80 columns.

I swear I tried both and both triggered the update,  but maybe refind was shuffling the menu order on me?

Or maybe there just happened to be a valid update when you tried....lol. At any rate I think one is a recovery partition that will always trigger the update and the other is the active one.

Those instructions are using rEFInd instead of Grub2.    I'd actually prefer to use rEFInd, however whenever I boot Atari OS with it it triggers "update mode" and the VCS will download and reinstall the latest update everytime you boot it through the menu.

 

What my instructions do is provide a way to boot AtariOS through grub without triggering that issue.    If/when I can find a way to do the same with rEFInd, I'd probably switch.  rEFInd likes to autodetect the bootable OSes available rather than you providing the list and special parameters

I installed refind and it came up with multiple bootable instances of AtariOS. One of the instances would trigger a reinstall, but the other doesn't. I just removed that instance from the refind menu.

Everything works on mine except the shoulder buttons. But so far I need to re-pair them EVERY time the connection is dropped. Anyone know of a fix for that?

You mean 1600 right?

 

You have to set it to 1600 for the 3200 mz RAM

Yes.  Runs fine at 1200/2400 but no go at 1600/3200. Tried 1400/2800 but still get black screen/full fan.  Can live with 2400...

[3200 MHz compatible memory for the Atari VCS - READ THIS BEFORE PURCHASING!]

TEAMGROUP memory is a partial failure for me at this point.  Bought from Newegg last week... Installed it and it ran great with default settings. Went in today and made the suggested bios changes for 3200.....black screen, full fan

 

Will go back in tomorrow to see if it will come back up after putting the old RAM back in and going back to default settings.....

 

 

[130XE with Turbo 816 OS - strange mod]

Looks like the CPU had a socket added too.  There was probably an 816 board plugged in there at one time.  That switch tho......

[SALT test fixture - schematic in CAD?]

I got mine from Brad at Best Electronics.  I finally pulled the trigger because someone posted that he only had a few left though.  It looks like they may be out of stock now.

How good are these things at diagnosing issues? 

 

Seems to do a pretty good job.  I just picked one up recently and tested several 8 bits that seemed perfectly functional.  It identified problems with several of them that I would probably never have noticed without it.  The long burn in tests are especially good in finding faults that are intermittent.

Haha... ok, glad I alerted you in the appropriate season.

 

Thanks for the board pictures and ROM dump, btw.

 

Well, so far rooting about has not yet yielded the manual.  Searching my email does reveal that I should have a photocopied manual somewhere. Apparently Rory McMahon was kind enough to send this to me way back in 2005.  We also discussed the disks.  He was going to check and see if he had them in with his boxed Amdek III, but it doesn't look like either of us ever followed up on that.

 

Back to rooting.....coming across all kinds of stuff I'd forgotten about!

Ever have any luck coming up with the manual for your Amdek?

 

Not yet, but it's finally cool enough to go rooting about in the garage...LOL

Saw that on Facebook too. Was hoping it wasn't true. Very sad! R.I.P.

I've scrounged three floppy drives, all Teac: FD-55BR-100-U, FD-55B-01-U, and an FD-55GFR-7149-U5.

Those drives should work fine.  I currently have a FD55B-01-U and a Mitsubishi M4851-112U running on mine.  Make sure your jumper settings and termination are correct.
