Title: Zorro SCSI controller
Post by: pyrre on July 25, 2008, 06:01:28 PM

I have a trumpcard for my A500. And i have severe problems getting it to use newer disks. And all the information i can find points towards a limit of maximum 250mb disks. the disk i am trying is 300 (something) mb.
However.
The trumpcard is basically just a zorro bridge. meaning i could use any type of zorro scsi controller. supposed it fits inside the case.

Anyone having a zorro scsi (IDE will also do just fine) controller they are willing to part with?

Or a SCSI disk smaller than 250mb. (a quantum is preferred since there is drive tables for quantum drives included in the disk setup tools.)?

 I think the best you can do is attach a decent full-size controller instead a small card.

 The case won't fit? And so? Better make another case and use a controller who adds RAM to the system, like A2091 or a GVP HC8+. :idea:

I have 32MB of ram on the derringer, so ram is not an issue...
I just need a decent controller.
And i am beginning to consider this (http://amigakit.leamancomputing.com/catalog/product_info.php?cPath=42&products_id=486&osCsid=aa63aa896bf505d8b8e98ad4f2a2d681)

SCSI will serve you better. IDE is very CPU intensive....

Well. that is not really any concern, it is only going to be used for retro gaming. And with a 030 @50mhz it is more than enough for its purpose.

The A1200 is used for more serious business...

Yes, I have an ADSCSI card lying around.
Last time I tried it (about one year ago) it was O.K.

Did I get you right - you want to fit it to an A500?
Do you have an Zorro bus board for your A500 (I still have a new and unused Micronik Zorro bus board for A500 (from Micronik's A500 tower conversion kit) plus keyboard adaptor lying around as well...)?

@Dandy

Hmm... tempting.. But i do not have any towers for A500.
I do have the trumpcard (http://www.amiga-hardware.com/showhardware.cgi?HARDID=1213) and it basically provides me with two zorro slots...
The original controller is very twitchy about disks. and cannot use disks larger than 250mb...
And the only "small" scsi disk i have is 300 something mb...

What ADSCSI do you have? full length zorro or half length?

 A friend of mine tells me his SCSI controller not accept any SCSI HD on the 1Gb~10Gb range.

 Oddly enough, he toss a 73Gb(!) on the chain (for termination, only) and the HD works!!!

 Hmm... time to drag a big HD from the street... :-D

I have an eight connector SCSI cable with a passive terminator on the end... But no large disks...
The largest one is 9.1GB
