Amiga 500 4/8mb fastmem boards with IDE

[scoobyatgb]

Interested in a 8mb version and adaptor for my amiga 500+ Also could you but a lead off it for a led so I can see cf access but can you answer 3 questions first will my 1. amiga a590 still work 2. Will my action replay mk3 work 3. My rom switcher with 2.04 and 3.1 work

Thanks

Hi All,

I have 15 ready for mailing, i'll send out emails later today. check post 1 for the list to see where its up to

Item received today, and seems to be working fine. Just installed it in my 500+. All 2+8MB RAM is present and it boots from the CF card. It is currently running mem tests, but after 20 minutes there's still no issues, so it is probably good.

I do get a PFS3 popup requester with some error when it mounts the CF partitions, but they do show up in WB and seem to work so I probably just need to repartition the card since the image I wrote onto it was from some other CF card.

Will leave feedback.

Edit: Feedback done. 1½ hours in, the memtest is still going strong, so still looking good.

Edit2: Just tested the AR MKIII in the 500+ with this board installed.. Not a good idea. Various colors appeared on screen and the floppy drive made a horrible noise. After this, the floppy drive wasn't working anymore. Turns out the head had gone off the spindle and couldn't be pulled back by itself. Pushing it physically back onto the tracks fixed the drive and it's working fine again. Lesson: AR does not like this board, or maybe even any uncommon memory expansion.. Consider yourself warned.

about Action Replay 3...

The AR3 requires to load into memory at location $400000, so the way to get around this would be to use the non autoconfig code and use addmem to avoid memory location $400000 - $4fffff... However... I also think there is a conflict with either int2 or the OVR soignal... there may be a way around this be using a different int... its too high above my head,

If the AR is using $400000 for itself, then I don't think the non-autoconfig version would change anything since it will still put memory at that address which would conflict. I'm guessing the AR doesn't care much about using system routines, e.g. for memory handling? In that case, it doesn't care about autoconfig.

Anyway, I'll just use the AR on my plain 500 with ½MB+½MB, to be upgraded with HxC. That should work fine.

with the addmem command you can addmem in portions, for example...

addmem start 200000 to 3fffff

addmem start 500000 to 9fffff

those commands would give you 7mb of fastmem and leave the 400000 - 4fffff range for the AR3

There will be something new soon i think... you will be able to use a Raspberry Pi as an internal floppy (quite possibly with IPF support), or so i hear

The addmem command only tells the operating system where memory exists, it doesn't change whether there actually is memory at a specific location. And if AR ignores the system, then the memory might have to be physically disabled for it to work. But it could also be the AR conflicting with the autoconfig procedure in the KS which causes the problem, and in that case, autoconfig disabled might be enough.

I have not yet bought a HxC for the same reason, I'm looking at what alternatives is out there, and I'm not in a hurry.

Package received yesterday!

Hope to be able to play with the cards soon....

Declaring interest in 8mb version. Sending PM

Withdrawing my interest because of the installation process in an A2000 seen on Kipper2K website... (CPU fastslot is already used by the accelerator board)

One last question before I proceed with payment since I'm in the next batch of buyers. Will this expansion work with my Alfadata RA5-2M ram and how much would be the maximum Chip/Fast ram I could achieve with my rev6a A500? Could you possibly make a guess Brian?
