Wanted: STE Bottom Case and Floppy Drive

Pretty much as the topic says, looking for a nice bottom case and a floppy drive that works. Short button.

FS: 1040 STF in box, matching serial numbers.

This is a US unit, no mouse, no power cord. It didn't have a top shield for some reason, I dug one out of my junk pile and installed as I didn't like having the PSU un-protected. Looks like an early TOS version and the DMA chip is socketed. I don't see any re-work on the board. Case is in great shap...

New Source of ST mouse switches.

I know there are a few different mice and switches for the buttons, but I found for my STE mouse that had a bad left button, that when working to repair a 6 year old Xbox one controller with stick drift, it had the same size buttons. Figured a six year old used one was better than a 30 plus one and ...

For Sale: 1991 PSU for UK 520STE 1040STE

I have just finished fixing a UK STE but I am in the states, and have no use for the PSU as its only ~200 plus volts AC. I kept the sled, wiring harness for the motherboard and mains socket/switch since I built a new PSU for myself. This was tested in the UK before the system was sent to me, and pow...

Re: Atari STE with T0 and e7 spurious interrupt

And I forgot in my pile of stuff I have an exact drive, epson, that works perfect in the STE.

So for once it was something simple. Now to find something to run on this bad boy to test it out.

Re: Atari STE with T0 and e7 spurious interrupt

Ah great test pattern, I didn't think of using emulation for expected behaviour.

I have an external drive, just no PSU :)

I did a few more tests, it looks like its not able to do a seek to track 0, so could be mechanical or electrical.
