Amiga 2000 Technical Question

[mrnukem]

I am now the proud owner of an Amiga 2000 I found at a local thrift shop. I had some question about it though. It says Amiga 2000 Supra drive on the front, inside it has 2 hard drives, one mounted on a controller card and one mounted in the drive bay.

I was looking up what a stock Amiga 2000 has but when I ran a system information program I got the results below. Has this unit been upgraded or was this configuration one of the standard versions commodore released?

I am more familiar with the Amiga 500 which I already own.

Thank you

The 2000 came with a straight 68000 processor. Some were sold with an expansion card already fitted in, but it was very common for them to be upgraded in any event.

Way upgraded... CPU, RAM, FPU...

2096128 CHIP.... NICE...  not a common upgrade...

For more info you should take it apart and check everything including the battery.

It looks like 1 of the hard drives is not mounting. I think each is a 50 MB drive. I have 2 partitions each 25 MB but I get a drive 1 not mounted error-message when the machine boots up loading the Supra II start up sequence

if you press both mouse buttons an early boot menu may come up. you may be able to deduce  something by going in there. You can also run hdtoolbox to see if the drive is recognized in there.

Nice find!  Take the lid off again and look to the right of the Zorro slots (and to the left of the floppy drives) and hopefully you'll see a 68030 CPU card in there.

Is that "controller card" in a Zorro slot?  It might actually be your CPU card with a SCSI controller on it (which is what mine has).  If that's the case then you also appear to have 8MB of RAM on it(which is better than some old Zorro SCSI card with 8MB).

Although you might have a CPU card with RAM plus this Zorro SCSI contrller from Supra:

Also, somehow your Chip RAM has been upgraded too!  You might be lucky and have one of these:

Check your battery too.  Either someone has removed it (hopefully) or it is leaking all over the motherboard.

Here are some pictures. Also a very odd little 9 pin plug was in the far right front joystick port, just a 9 pin F encased in small black plastic and a printed label that gives a long serial number.




As far as the hard drives go this is what I have so far:

When I run a program called Sysinfo that I found online under SCSI it says this

ID 0 DISK Quantum LP52S Model 950509405 Ver 2.6E Max Blocks 0 SCSI-2 Real ? Format ?

ID 2 DISK Quantum LP52S Model 950509405 Ver 3.1 Max Blocks 102170 SCSI-2 Real 49MB Format 49 MB

On same screen ID 1,3,4,5,6 all say IO Error or HD_SCSI Command Not supported by the device driver.

On another part of the sysinfo program it says I have a 68030 running at 51.80 Mhz not sure if that will help ID the upgrade. The hard Drive is my main concern, hate to have a 2nd drive in there not being used.

Thanks!

Hmmm....it's interesting that Sysinfo says you have a 68030 CPU when there's no CPU accelerator card in the CPU slot (or did you just take it out before taking the photos?).

In the first photo, all I see is a RAM expansion card and a hard drive controller card.  The slot to the right of the hard drive controller card is the CPU slot.

No I never touched the CPU, jst took out the 8 MB memory card but other than that nothing has been changed or removed. Could Sysinfo be wrong?

Look at the 68000 socket and see what might be hiding there

The CPU card could be under the HD bracket, plugged to the 68000 CPU.
I see something there. Looks like A500 type of CPU expansion card.

I was wondering the same thing about the CPU.  I have to assume he has something like this:
http://www.amiga-hardware.com/showhardware.cgi?HARDID=63

It is a 68030 & FPU card for the A2000 that actually plugs into the CPU socket rather than the CPU slot.  It also has a jumper to switch it between 68000 and 68030 mode.

could be - would not be surprised, i mean if it has 2mb agnus upgrade(not too common)

that system would be sweet with an Indivision AGA

i would totally dump all the SCSI drives and go for

Sounds like a software dongle.  Required to run a specific piece of expensive software.
The idea was to stop software piracy.

I guess you have a Mega Chip 2M Board attached to your Angus slot (http://amiga.resource.cx/exp/megachip) and a Derringer (http://amiga.resource.cx/exp/derringer)or simular 68030 card in your 68000 processor slot.
Both of these are under the Powersupply/floppy drive chassis.

Sounds like a top unit.

Should check the condition of the Battery.

I wouldn't worry too much about the 50MB SCSI as is fairly limited for the space it takes up.  You should be able to score a 1GB SCSI somewhere.  IF not go the SCSI reader option as suggested.  Instant 2GB.

Congrats.
