The fastest IDE interface for the A2000 reaching speeds of 10Mb/s and it went for £11.50

How come I never get auctions like that?

I bet moparart101 is doing a happy dance about now.... and for some time to come methinks.

isn`t this card also auto-booting as well ?

alexh · 15 January 2007, 22:28

Yes it is autobooting, 8Meg FastRAM upgrade and the fastest (low cpu) IDE controller ever made for the Amiga

hey alexh, u must know.... why the hell don't they make IDE DMA controllers for the amiga???

alexh · 15 January 2007, 22:38

To be honest I dont know. I suspect a combination of:

1) Lazy designers (IDE lends itself to PIO and SCSI to DMA)
2) Price (PIO design is much cheaper than custom DMA one)
3) PIO mode (16MB/sec) being faster than the Amiga's DMA channel (which tops out at 10MB/s) with a good (060/PPC) CPU.
4) Technical problems? Can you DMA to FASTRAM? (I really should get to know my DMAC/Agnus/Alice capability!)

Pity those fuckers won't sell abroad even if I pay insured airmail.

Take heart, there's a Cyberstorm PPC card up for auction at the moment that shouldn't go for much over AU$1,000......

How good is a 10MB/s card on a ~3.5MB/s bus?

Zetr0 · 17 January 2007, 06:33

@adolescent

about 7MB/s my friend

adolescent · 17 January 2007, 08:22

@zetr0

Must be one of those magic Zorro II buses (or a Z IV?). :P

alexh · 17 January 2007, 09:36

The "Blurb" says it reaches peak speeds exceeding the Zorro theoretical limit of 3.5Mbyte/sec using:

Quote:

ultra-fast "Hidden DMA" transfers

Add to that "it doesnt work on a Zorro III bus (i.e. A4000/A3000)" says to me that they are probably doing something on Z2 which is illegal but works for the A500/2000.

Reviews at the time said that it was significantly faster than a GVP HD8+ with a GURU ROM
