A590 ROMS..

[giZmo350]

Hi all... Is here a way to tell which version ROMS I have in my A590 by what's printed on the ROM chips themselves? Thanks in advance....

Thanks for the reply Jeff...  The chip I'm looking at doesn't have an identifying label. It only has printing on it. Here is a pic of the actual chip... can the version be determined from this?




Also, can you tell me what the difference between V6.6 and Ver7 is? What I'm trying to do is determine what SCSI HDD I can replace the original XT HDD with. I have a Quantum 4550S SCSI 4.5 GB HDD 80 Pin that I would like to drop in. I know I should be able to figure this next question out myself but, what adapter or cable do I need to go from the A590 straight 50 pin connector to the 80 pin high density HDD connector. Do I need to still use the power connector in the A590 for the SCSI drive or is that for the XT drive only?

This next question is a doozy....  how can I transfer all the data from the XT drive to the SCSI HDD?

Also, can anyone confirm that the Quantum Atlas II 4550S / PN HN45J011 is really an 80 Pin drive? There is so much conflicting info on the web.   :-?

Also, please don't think I'm just trying to leech quick info from you guys....  I've been searching Amiga forums constantly to accomplish this project. Thanks Again!

No, anything could be written to that chip. Do a 'version scsi.device', maybe other folks here with an A590/2091 are kind enough to post their ROM / device version numbers for comparison.

>> OK, the pic of the chip is the one for sale from the web... looks as though many are bought from this guy so should be what he says it is.

Sounds like an SCA drive, so you'd need an SCA -> 50 pin adapter. If you're not planning to use a longer bus, you can probably get away with a simple adapter w/o terminating option, otherwise you'll need a better one with terminator.

>> Yes, I beleive it's an SCA drive. So, will this work? Has anyone else used one of these?



----------------------------

That power connector will do fine - if the drive has one (see below).

>> So, I will be utilizing the power cable from the A590 to this power connector on the adapter pictured above?

-----------------------------

> This next question is a doozy.... how can I transfer all the data from the XT drive to the SCSI HDD?

Well, it's either backup/restore or hook up both simultaneously (with a Y-adapter for power).

>> Sweet! I can have both the XT drive and the SCSI drive connected at the same time to the A590?

----------------------------------

> Also, can anyone confirm that the Quantum Atlas II 4550S / PN HN45J011 is really an 80 Pin drive? There is so much conflicting info on the web.

>> OK, there's NO power seperate power connector on the Quantum SCSI drive so I will assume it's an SCA 80 pin.

---------------------------------

Count the pins.  If there's a power connector on the drive, it's wide SCSI (68 pin), so you'd need an adapter for that. 80 pin SCA includes power, so there's no separate connector.

I bought the ROMs here..........
The guy has over 20 sets to sell.... Seems like a reasonable price too.

ROM V7.0 for A590 A2091 SCSI adapter for Amiga 500 2000

So, is all this do-able as described above?
