oh well least it was cheap and came with the mac roms
so next card needs H rev chips I`l try remember that, thanks

Yes, it's nice to have a set of those.

Not quite. The only difference between A-Max II+ cards shipped with the A-Max II and A-Max IV emulator software is that the latter cards have the Revision H IC5. The Revision H chip incorporates changes that handle the new A-Max IV-only 720K formatted disks properly.

Edit1: The only possible disadvantage of the Revision H version of the chip is that using it may sacrifice backward compatibility with floppy disks formatted with earlier versions of the emulator.

The reasons I am not certain about this are twofold:
(1) the documentation is inconclusive, and
(2) I don't, as yet, have a Revision H chip with which to try it myself.

Edit2: If the Revision H chip does ruin the backward compatibility of the emulator, then you really need to own both versions, which is why I would willingly buy another card just to get the new chip.

Hey guys,

Here is an item from USA listed on eBay.

It's an A-Max II cartridge.

And I thought all A-Max IIs were Zorro cards.

The seller's description reads as follows:
Here's an item for all you Amiga and Mac collectors that doesn't turn up very often. The "A-Max II" is a hardware emulator that plugs into your vintage Amiga and lets it run vintage Macintosh software. This one appears to be new in the box, with the manual, software, and registration card.

Hi prowler,
yes, I remember that A-Max II was very different (a lot less advanced) from A-Max II+ / A-Max IV.
A-Max II (v2.5 included) was available on cartridge.
I suppose/remember that the cartridge was identical to A-Max I. Only the software was different.
It was essentially a ROMs holder with some more electronics...

Hmm... That'll be the Macintosh floppy drive interface. I really didn't know that an A-Max II cartridge was released. I imagine that the only new "feature" was discontinued support for Mac 128 and Mac 512 64kB ROMS.

I don't think it's a different cartridge from A-Max I...
If you look closely at the photo, the cartridge has the A-Max logo, not A-Max II. I bet it's the same interface of the first A-Max release.
After all, the A-Max II software is not very different from A-Max I. Just an "upgrade". Unless I'm getting old... and I'm confusing A-Max II with A-Max I v2.5?
I have A-Max 2.5 and it perfectly runs on my basic Amiga 600.

Hey, when did you get that, mate?

That's the first time you've mentioned having A-Max hardware that I can recall.

Oops, no, sorry, I didn't specify: A-Max v2.5 cracked version (runs without additional hardware)

Is there any way I can get the Mac system disk in ADF format (without virus please) for A-MAX 2.5?

I would like to try and run A-MAX on a Minimig 1.1 with 4MB RAM.

I have been looking at ways to create this on my PC with UAE and ShapeShifter and vMac but I have been unsuccessful.

Thanks!

Hi Nate,

Thanks for your interest in this emulator.

Unfortunately, you can't create a Mac System disk image in 880K ADF format.

For use on a real Amiga you can convert 800K Mac System Disk Copy images into A-Max formatted disk images by adding a small header and these may be written to disk using the Emplant Disk Converter.

For use in WinUAE, it is possible to convert Macintosh disk images into extended ADF format, as Supamax has done, but I'm not sure if they are compatible with the Minimig.

Hmmm, I suppose that the Minimig is able to use (read&write) advanced adfs... or not?

I dont think it does - I hope its ok I pointed bbond007 towards EAB
I think he'd like to setup a HD, I think A-MAX4 might work with SCSI.Device but I never got A-MAX4 working properly.

Looks like AMAX IV requires a 020 or better CPU. Although my Minimig's 68000 runs 030 speeds lacks the 020 specific instructions

I have been looking for info on the Minimig as far as support for extended ADFs. It looks like the PIC controller does not support it, but I have the ARM controller so maybe it will work.

I just wanted to see it boot for the novelty of it

thanks,

Theres some stuff in the link below about hardfiles and A-MAX but im not getting it
http://www.amigahistory.co.uk/hardfile.txt
Also whats the RAM DISK options for?
Anyway its sparked an intrest for me.

:How do I Quit from A-MAX back to WB??

If only we could get it working!! I'll give it another try as soon as I can.
Once/If we can run A-Max IV, we'll be finally able to write an empty disk (or empty extended .adf file) and make some disk tests, and we'll discover something more about its new 720K disk format.

Retro1234 · 21 December 2011, 23:56

Sorry guys if im taking this off-topic

Do you know if any version of A-Max can quit back to WB?
Can the File Transfer utility write to Mac/A-Max Ram Disk?
Which of the System disks had viruses?

The problem that bbond007 had interested me and the fact that eADF not easy to write and just booting with out Floppys

Ive had some luck with a dodgy utility called AMAX_RAM_v1.1 this can save the Mac Ram Disk to file after a reboot and be loaded later, using AMAX 2.0.

So if you copy the System disk to Ram Disk under A-Max save to file you can boot without floppy.

AFAIR A-Max 2.x can be installed to hard disk, and it can be booted without floppy.
But you're probably referring to the MAC boot (not A-Max boot)...
I'm almost 100% sure that A-Max II+/IV can boot from HD, but it needs a dedicated partition.

As far as I know theres no .amhd driver that will work with A600/A4000/A1200 ide controller maybe theres one for other HD supported by WinUae but this might be the only way on A600/MiniMig.

A-MAXIV does support SCSI.device but is 68020 only and superseded by ShapeShifter.

Hey Boo Boo,

Do you have the CAM #573a&b Émulation disks?

cant seem to remember where I downloaded it from but if its any use to you ill Zone it
