  1. Does the drive spin the disk when it is placed in it? Have you got the floppy cable in the right socket (there are two on the back of the drive)?
  2. There is a list and photos of a lot (all maybe?) of the motherboard revisions here. http://www.atari-wiki.com/index.php/Atari_ST_motherboard_revisions A diagnostic cartridge might also be a good idea, once you have recapped the PSU (or replaced) as Paranoid suggested.
  3. I don't know whether your VGA cable has an audio out? If it does and you press a key and get a beep (keyboard click) or repeated beeps if you hold down the key the ST is probably ok, but the cable might be a problem. The disk drive is quite likely to be faulty at this point. You could try using a floppy disk cleaner to try and clean the heads, or do it yourself if you are happy to open the drive and clean the heads with isopropyl and a q-tip or similar.
  4. At least one Atari monitor had stereo speakers afaik, but the monitor output is in mono even on the STe I believe, so presumably you needed to hook up the RCA jacks somehow to get it to work on that model.
  5. Ah that explains my very quiet key clicks (I thought I was going mad). Seriously though, a contrast icon!?!?! I had twiddled that wheel many times with no visible effect on the picture and as it was on my serious ST I hadn't noticed it controlled volume.
  6. The original ST and STM don't have joystick ports on the keyboard itself as Atari had the ports in a sensible place on the early release, so if you have one of those you will need to find a specific keyboard I think, as from a physical perspective at least a 'newer' STF keyboard won't fit. STF, STFM and STEs (and even Falcons) should be fairly easy to source a replacement for as the keyboard is the same. I don't know if the keyboard will work if you remove the joystick ports, presumably it just as some additional circuitry to complete the port circuit, but whether there are connector differences where the keyboard attaches to the motherboard I'm not sure, I seem to recall the connector was different (longer I think), but I haven't opened my early STs for nearly a decade. If you glue the broken bit back in position you could repair it by scratching back to the tracks on either side of the break and using conductive paint to bridge the gap if you don't want to get soldering and using copper wire on the go.
  7. Pure guess as I'm not familiar with the company that made this, but it looks like a accelerator card, probably for boosting the system bus and overclocking the CPU. What's it plugged into and where are the wires going? The easiest way to check would be to run something like Gembench on Lo and Hi and see what the difference is.
  8. I suppose a recap (on the drive) might be in order if you really want to get it going. But I would also recap your PSU if you haven't done so already. Really though unless having the original is necessary I would probably go with Paranoid's advice.
  9. Is this the single sided drive belt version? Probably best changing it out if it is, as it will not work with double sided games/ apps anyway.
  10. Mine always did with my STs, iirc it did not require one with the TT. Always presumed it was the TOS version, all the STs I tried it on were 1.02.
  11. Hhhm I suppose the other things to check are.. The cable (ribbon cable) between the ST is ok - perhaps replace (again as Paranoid mentioned)? Might be worth checking over the Satandisk for any soldering faults - iirc these were put together by hand, and a small bit of soldering error like dry solder joints, could cause an issue. Try another Satandisk psu Of course there are the general things like reseat socketed chips, recap motherboard and so on. I'd be surprised if the DMA chip is to blame, but perhaps replacing it might put your mind at rest
  12. Does sound like the Exxos unit may be faulty. Part of the 'fun' of using the ST was hitting its memory limits, first trying to run something like Write On in 512k and realising that you can only use two fonts, then upgrading to 1mb and realising Magic has stolen most of that. 2.5 was workable - 1mb for multitasking system and font system with trimming and the remainder for use. No matter how much you have you eventually run out on the Atari, I used to run out of memory on my 14mb Falcon. It wasn't until I had 64mb on my Milan that I was free from the out of memory blues.
  13. There is a resister patch you need to do if you have the original Satandisk (rather than Ultrasatan) which might fix your problems. I had partitiion loss with my Satandisks and my Mega ST 2 before I got it done, afterwards no problem. Its a fairly easy mod even if you have only a slight bit of soldering skills. Check for the power off partition loss link on here.. http://joo.kie.sk/?page_id=86
  14. So have you deactivated the onboard memory when you try and run it in 4mb mode? I used 2.5mb for quite a while back in the day and it was more than enough to run most things, Magic and Geneva should run fine with it (even with NVDI, although you might want to trim the font use down a bit and lower the print and font buffers - and maybe trim those auto folder programs and accessories). You'll only run into problems if you try and run Mint (which isn't much cop on a ST anyway) or load large pictures (or a picture heavy WP file) for example - but even a 4mb ST will choke on most JPEG files, it probably won't even load a single modern JPEG before it runs out of memory. You can quite happily run a multitasking OS and pretty much all the software out there for the ST, remember 1mb was considered standard by the end of its commercial life, and many users were still using 0.5 and getting away with it. I would suggest running single tasking for memory intensive stuff. You could probably use Teradesk as a desktop as it is pretty memory light. Really if you want to run a NVDI contemporary 'power user' system from back in the day you need at least a TT or a Falcon (pipe dream as that may be for most users today) or a ST fitted with a 12mb upgrade, a graphics card and 030 accelerator. You could also try some different software, I don't know what you want to run, but That's Write is a decent WP for a lower end system and comes with a built in font system. NVDI 2.5 or Warp 9 could also be an option as they don't use as much memory as a full fat NVDI or Speedo GDOS system. Or you could even install a blitter and then you wouldn't get as much benefit from the screen acceleration portion of NVDI anyway - the blitter does make a hefty difference to desktop usage.
  15. Ha, not sure how that happened, I wasn't a massive fan, and probably dozed off during that moment (think I was just waiting for Harrison Ford's cameo performance). For some reason despite all the CGI it didn't look as convincing or spectacular as the original (to me anyway). Still it was better than those Star Wars sequels.
