A1200 + Blizzard 1260 + Blizzard SCSI + ACard + CF test setup

Toni Wilen · 30 August 2008, 18:09

Perhaps pointless post but it works

(~7.5MB/s transfer rate)

Next task: build better and shorter cable..

Very nice

My problem is getting these things back together

Excellent work Toni!
We now have up to date confirmation that the Acard SCSI - IDE bridge adapters work with CF on SCSI chains.

Post your intent to buy one from AmigaKit here:

I already have 2 ACard's (one in CDTV, another in Supradrive 500XP), I guess I need 3rd now

(2 previous bought from Vesalia)

What SCSIDE are you using? Any chance that the case will close? I was hoping to find one of the OEM 2.5/3.5" chassis models but haven't seen one in a while. There is a Japanese SCSI-CF that is in a 2.5" SCSI form factor that looks good, but would need an even more custom cable or an adapter.

I'm working on making a cable myself now. Planning on doing the Blizzard SCSI -> 50 PIN (maybe two for future use) -> 50 PIN SCSI-2 External. Main problem is time.

That's pretty convoluted. How fast is a CF card connected to the 1200's IDE controller? I suppose this method utilizes less CPU? I don't know how smart the Blizzard SCSI add-ons are.

Calgor · 31 August 2008, 04:46

@Toni

Can the acard adapter fit in there with the case closed? I take it that was your point in testing this (or otherwise possibly just for kicks).

May need to get the 50pin version for this.

@gklinger

Blizzard SCSI kit utilises DMA, so yes.

gklinger · 31 August 2008, 05:40

Hrm. Now you've got me thinking I should get a Blizzard SCSI (impossible though that might be) because the relatively slow access of my CF card is bugging the heck out of me.

I will find a way

It is but this is something I have always wanted to do

~2.5M/s max with accelerator + 100% CPU usage. For some reason all Amiga IDE controllers are PIO-only.. (Remember that there was singleword/doubleword IDE DMA modes introduced years and years ago before UDMA)

It is DMA controller

Gotta love the hardware shots. Great stuff Toni!

gklinger · 31 August 2008, 18:52

Convoluted though this setup may be you are getting three times the throughput and a fraction of the CPU usage? Wow. Now I'm really impressed.

Could you post more pictures, please? I would like to see exactly how you've got that all hooked up. TIA.

Nice R&D work there chap

CF-IDE adapter and ACard separately and another alternate angle shot. Hope this helps.

I have 2 blizzard scsi adapters i may considder selling one ..

Was this adapter 50 pin ? would suit great in my scsi box :-)

Photon · 19 October 2008, 02:28

Just ordered the same setup for my A500-040 8)

DDNI · 31 October 2008, 01:53

Is power required to both the acard and the CF adapter?

Try transferring gigabytes over. I've got 4+ GB of WHDLoad installs and copying them over to my CF card was a long process.

Photon · 01 November 2008, 18:12

Toni, why have you move the jumpers from the default? No ID 6, no termination, no terminator power? I just got the same setup and am wondering if the defaults might be non-good.
