Info on running an A2091 on an A500

[kjmann14]

If anyone has ever tried to run a 2091 Hard drive card on a Amiga 500, you probably know that there are some issues with doing this. But the A2091 is probably one of the easiest HD cards to find for the faithful amiga.

This is a step by step instruction on how to make this work correctly.

DISCLAIMER: I Am NOT responsible for you screwing up Your amiga,
2091 card, Or anything else for that matter. you do this at your own risk

1st off you need an adapter card. The spirit zorroII 100Pin to a500 adapter is a good one, but it's setup at an angle so the 500 has to be raised up

But this is not the major Problem. a couple of the right sized two by fours under the amiga will take care of this.

The bigger problem is Setting up the card so It can run properly WITH Removable media.

from here you need to have at Least the 6.1 Roms in the 2091 card. 7.0's are preferable. You can get new 7.0's HERE

Next is your Hard drive Unit ID. The 2091 is picky and in order to run removable media without screw ups you MUST set the Hard drive SCSI ID to 6. Nothing Else. All Removable media is set to a lower number. I know this is backwards from the norm but it will solve your removable media problems for the most part (CD drives, Zip Drives, Etc.)

next is the reset problem. You must run a jumper wire from pin 94 to pin 53 on the 2091 card. this will enable the 2091 to receive a Reset signal when the Amiga does a warm Boot (Ctrl-Amiga-Amiga or Program Soft reset)

That's it everything should work fine from here.

Enjoy guys!!!

You just have to look around for them. There are 2 models That I'm aware of.

1. The Slingshot adapter - made by Pre'spect / BSC, Canada Picture here

2. The One Made by Spirit - name of the device unknown.

Sorry I cant be of more help.

Those adaptors will cost more than the price of an A1500/2000 though!

Better option is to get the ICD internal IDE adaptor for the A500 (which works on the A1000 too I guess) and go that way for faster quieter 2.5" notebook IDE hd drives

I have just finished talking to a friend of mine that owns a company called illumitronics. We are going to manufacture a board like the slingshot and is should retail for about $25 to $50 USD

BTW. I bought my spirit adapter for $28 USD
