Time has come to extend beyond retro console mods and go retro amiga....
Currently it's in the planning stages (parts en route etc..), but the plan is:
Ditch the original Amiga PSU, place an internal ATX->Amiga Power adapter inside, place a tiny ATX ("picopsu") power supply inside, so the whole unit can be powered with a 12V DC supply.
Replace the internal HD with a compact flash (obvious advantages). Planning to use the DMA-enabled scsi-2 controller (part of a Blizzard 030 accelerator) as well for speed/low cpu usage benefit, so will be installing an internal Acard SCSI-IDE bridge.
Install an internal cdrom. Room for a slimline notebook one - again considering getting this on the SCSI chain, meaning another SCSI-IDE bridge - so space is becoming an issue! If not, can always hook it up to the internal IDE controller (via a JAE notebook cd -> IDE adapter).
Possibly - another compact flash - this time external, for easy access. Might be overkill though - could just get a pcmcia->CF adapter and use that...
Go wireless - with a PCMCIA wireless card for wireless networking.
That's it - Can't think of anything else an Amiga needs!
(Considered a flickerfixer/scandoubler to allow amiga to be used on a VGA monitor, but from pics I've seen they are a bit limited and you get acres of unused space on the screen. Basically this needs to be used with a 15Khz CRT monitor - and I've got just the 27" job....)
