Hi,

I have recently bought some Apple II cards. One of them is a Corvus Systems (Rev 1) that seems to be a Hard Drive interface card.

I don't have a hard drive to test it, but although it has some rework on the backside it looks pretty good.






Any comments will be really appreciated.

Thanks,
Jose Luis

Hi @Jlgarcia! It seems to be an early version of the Corvus hard drive interface card that connects to a Corvus external hard drive. Here is what a later revision card looks like. :)

Those cards were produced for the Apple II, Apple II+, and Apple //e in 1980 and later. This particular card was tested by a Corvus employee named Don M on September 9, 1986.

And this is one of the brochures for the Corvus hard drive.

Hi @retr01 , thank you for the update, it's an interesting card, and whatching your pcb layout I can see how it has changed through the years.

It wold be great to get one of those HD and give it a try:)

Could it be possible to connect any other HD using this card?

Cheers!

Those are hard to find. I just saw one on eBay:

Since this is a Corvus interface card rather than a SCSI card, I am unsure about connecting to other external hard drives. Corvus was developed and produced around the same time that SCSI-1 was developed. The Apple SCSI (and perhaps others?) card was then created and marketed later for the Apple II series to connect to a wider variety of external hard drives.

Here is an advertisement for the Corvus Hard Disk system for the Apple II in the November 1979 issue of Byte magazine.

I see, hard and expensive. Probably for me, been in Spain, it's going to be almost impossible.

Cheers!

Another Corvus for less. A project to restore it.

That makes sense, I will have to find one if I want to test it.

Thanks a lot for your comments, I have learnt a lot!

Cheers!

I am looking for a copy of this A4.7 firmware for my card, if anyone has the 2K binary file that I can burn into a 2716, I would greatly appreciate it!
Thank you!
