The A1200 was released around christmas '92, so it's OT. The A3000 is 1990
vintage, though.

Nope, all have controllers.

Definitely no such trickery. The only odd thing is that the IDE interface is
masquerading as scsi.device. The OS will be most content with drives below
four GB. This has been remedied in versions 3.5 and onwards, but you're most
likely running OS 3.0. This may be patched nevertheless, I'm running a 20GB
drive on a 3.0 system myself.

There is not a lot of space. Try to get as slim a drive as possible if you're
intending to use a 3,5" drive. You may have to cut away a bit of the
shielding, too.

AFAIK, it's unbuffered, but how would you go about frying anything?

Certainly. You could use SLIP, but the better route would be an NE2000
compatible PCMCIA network card. I use a CNet card in my A1200, and AmiTCP
(bundled with OS 3.9), otherwise available as a demo on Aminet or for online
purchase through, which includes an NFS client. I run an NFS server
on my 4000, too, so that my NetBSD machine might easily download things in the
file archive.

Most PC SVGA monitors won't sync low enough (15 KHz) for games, but they will
most probably run if you stick to applications. Just make sure to activate
VGA-friendly modes such as Multiscan, DoubleNTSC, DoublePAL and Euro72.
They're activated by being moved to DEVS:Monitors/ , and are otherwise stored
in Monitors/ on your Storage disk. You may possible have to copy VGAOnly to
DEVS:Monitors, or was it into WBStartup/ ?

You should try Personal Paint, too. I find it a more than worthy successor to
DPaint, and it's free on Aminet.
