People should have warned you not to buy a mediator. Beefed up A1200s are always problematic, but adding a bus board is a sure recipe for desaster. It's possible to get it working - if you're willing to sacrifice your first-born son.

I never heard of of a failing A1200 onboard IDE controller, usually people just break off one of the pins on the connector.

Since you didn't mention any details about your setup, here's some general pointers:

Start with only the bare motherboard and see if it tries to boot from HD (it probably won't finish booting, due to missing hardware - but if it starts, you A1200 board is fine).

Add one piece at a time, try booting from HD each time to see when it starts failing.

Try a different PSU, if you have one lying around. If the current PSU was part of an A1200 tower case setup, it's probably seen a decade or two of use already.

What's on the internal IDE and what happens when you disconnect the HD?

That's what happened to mine. It stopped recognising HD drives. I check the port and there was a busted pin. I don't recall busting it. Still unfixed.

I might have missed it, but I didn't see any responses to check the hard drive itself - given that you "can't feel the drive spinning" seems more like a hard drive failure, rather than a Mediator issue, or an IDE interface issue. I'd suggest trying another hard drive, if you have one.

Sell off the A1200 bits and get the Vampire V4 and A1222 and stick them in the same case.

If you've found a SAM440 an adequate replacement

Oh yes I have. And for the record, I'm not trying to sell anything to anyone, just sharing my 8 years of experience (bought my first Sam in 2009, switched to Sam Flex two years later).

I am having a very good experience with the Mediator Bus boards, especially the TX series. I am aware your mileage will vary but in it's defense, my A1200 Mediator setup puts my A4000/040 to shame. Not just because I am running an 060 at 60Mhz but the Voodoo 3 2000 16 MB card gives better performance than any of the Z3 Graphics card options on the 4000.

When I first tower-ised my A1200 back in 1998, I initially planned to expand around IDE.

However, I never managed to get any buffered IDE interface to work with my machine.

I managed to get a SCSI kit for my Blizzard and was able to add SCSI devices, just hung onto 1 IDE drive attached directly to the MB, until that died ~2009.

So you're definitely not alone in having IDE problems on the A1200.

I've sometimes been tempted to go back and expand it, but I swore never to spend more money on my A1200.

My advice would be to hang on to it if you can, but still get the A1222. As others have said, if you abandon the A1200, you may end up missing it.

Voodoo3? Yeah, a very good video card for the day.
I keep one around for booting systems with a PCI graphics cards.
I works more reliably with other video cards than the ATI/AMD cards I have.

Until I switched to a G5, I kept the Voodoo3 in my G4 as a secondary graphics card under MorphOS (as MorphOS only accepts one Radeon video card).

Drive works fine under winuae on pc. I will take it back to bare a1200 and see what happens. If no drive is connected I do boot screen it can also boot of floppy disk.

Interesting range of views on this thread. During each day I switch on a lot of Amiga original kit.

Here is the thing, I only have issue really with one Amiga here. It is an Eyetech EZ-Tower fitted with a Blizzard and all the various adaptors for the PC monitor keyboard and mouse etc. The problem cycles every three months or so. Nothing major. I just have to lay the 1200 mother board flat for a while, reseat all the odds and bobs fitted to the motherboard, press the Blizzard back up into its slot. Unhitch and re-connect the buffered interface and reset all the connectors to the hard drives, ZIp and CD. And then like magic she always fires up first time... She will run like that for three months or so then the computer will start to fall over again. Not a fan

Give me my 1993 Amiga 1200 with external SCSI running flat on the table that has worked without fault every single day since Nov 93 over any tower Amiga. My thought is that the kit is just not suited to stand that way round. I have a 4000d in a tower which has the same issues.

I have been mucking around with old XT drives in the 590 this week and I have six of them working here. It is not a natural consequence that the kit falls over. Hardly any of my stuff is not working and I have a lot of kit. I rarely ever have to go to the extremes of replacing chips and stuff. I had a pin break off on a 1200 mobo but fortunately it was the version with the removeable end section so I just swapped it out. The joy of having a lot of stuff is always having bits and pieces on hand.

I just don't hold to the view that you should ever consider getting rid of old kit if it means anything to you. It's not like it takes up that much space. And you may think the gear has issues but I would suggest with a little time and effort you could get the Amiga back on its feet. I have never given up on one piece of kit here. Machines like the 4000T were a pig to get running properly but I did it. The 1060 was a real struggle and took me months to figure out but she's fine. Its a passion I have and I guess I am the exception, but my plea.... don't sell or let your gear go. You are probably the only person that can keep that magic going with the kit you have. The Amiga deserves good owners. You are one. Don't give up.

wise advice & I also will add you'll have to pay much more to eventually got your 'real' gear all back...the cycle continues

I hope it isn't pin 20 that is broken!

I've had a resister fall off and need replacing but all IDE pins intact as of yet Some are a bit curved from HD replacements

Mmmm. I don't remember where that is. But it's at the top. Near the back ports.
