I updated the AmiMPC web with details of a new head unit I have been working on,
which is greatly improved over the old one. See the
web site for more info.
My new head unit looks almost factory, and features a digital potentiometer
based volume control. I think I'm finally 100% happy with the system!See the AmiMPC website for more

|What is it with ann posters and URLs? They almost always seem to forget to include the URL, and when they do they never make it a clickable link, you have to copy the URL into your address bar of your browser. Is it really that hard to properly include a URL???|

|The Big question is "How much are flogging a completed system for"?|

Obviously this is a hobby project, and a bit impractical for those of us not swimming in 1200s. That's not going to keep me from asking annoying questions, so here they are- don't take them as criticism. :) [I have deja-vu, so perhaps I said some of this before..]
Where does the dependence on the 030 come in? Is hitting the parallel port like that just too intense to play nicely with the disk accesses, especially with any additional polling loops for the controls?
As to the buffering- it'll protect from system latencies, but what occurs if the drive gives up on its own remapping algorithms and turns up a bad sector (you're using IDE, so I don't think you get to tune for retry-or-bust the way modern SCSI drives' mode pages would allow)? What's curious about the iPod is that Apple seems to have really engineered shock resistance into the system; one of the early 'look what we gutted!' pages noted that its little HD could be munged by pressing too hard on the lid, but that playback would resume afterwards. (I assume that would've caused a bit more damage than even a good HD could remap around; perhaps they have a mechanism to 'fill in' lost sectors from the buffer?)
Of course, now I'm thinking about alternative implementations...

|I too have been thinking about this project and some of the limitations....the first one I though of would be|
FS support for really large drives (ie 60gigs +)
corrupted disks from shutting down unexpectdly
Also boot time could be an issue....perhaps you could boot from a small PCMCIA flash card that was write protected? Would be fast in booting thats for sure. Also, instead of using a small LCD screen, how about a 5" colour lcd hooked upto the composite port. The only problem here would be track selection without having to use a mouse......howe about a tiny touch screen :) Are there drivers for these on the Amiga?
Just random thoughts.....

|In reply to Comment 7 (Francois Prowse):|
It uses PFS3 so there isn't much of a filesystem problem (in terms of size or corruption). As for no mouse, it uses custom written software to play the mp3's, so there's no need for a mouse (the buttons on the front panel are interfaced to the Amiga).

Yes I realise that it uses an LCD screen with several bottons to control tracks etc....just wondering what could be done to this setup to expand it....:)
