impressions:

nice machine , some battery leakage and green goo around it but vinegar and iso cleaned this up with a toothbrush ,a quick wash and left to dry.

duncan said it had issues with floppy access and joy up but as yet i haven't had either problems - still early yet.

mods:

Jumper wire and switch added to enable / disable termination on the HDD - for when i plug the ext dvd in.

further jobs to do.

acceleration of some kind.

Very sexy computer. Would like to get one someday.

One question, where's the stick for the on/off switch?

 

[mjnurney]

O - open
T - terminated

 

[LTAC]

A DENEB card will be perfect for this beautiful computer!!!

Very strange PSU!?!

 

[MZ3540]

What about the power switch?

Push - Computer turn on
Push - Computer turn off

 

[mjnurney]

yes thats in the top of the case

 

[MZ3540]

Ahhh, I've never seen the insides of an A3000 close up.
I'm off to find some tissues

EDIT: No wait, I got more questions.
How long is the scsi cable between the hdd and the external connector?
When you have the hdd termination set to on, you're gonna have this dangling cable with no termination.

 

[mjnurney]

The eternal scsi connector is mounted on the motherboard. the internal connector goes to one scsi hard drive.

to use the external dvd rom - i plug a cable in to the socket at the back / flick the switch and turn on

very nice

Nice system

Don't forget the INT2 mod for further fast SCSI add-ons (Fastlane ZIII etc...)

What revisions are your Buster, RAMsey and DMAC?

 

[mjnurney]

haven't the faintest idea

 

[lostrego]

DMAC is the large chip located next to the roms sockets.

Ramsey is the other one large chip next to the super buster , the 68030 and the cpu slot (its position is usually marked as "ram controller" at the mobo).

Most probably that it have the Ramsey rev 4 + DMAC rev 2 combination as was usually on 3000Ds , this means problems with the C= A3640 040 board and SCSI DMA transfers if you try run the 3000's onboard fast RAM in static columm rather than fast page mode or some such, if I recall ok.

The Ramsey rev. 7 + DMAC rev. 4 combination do sort out this kind of issues, but the DMAC 04 is a really (if not impossible) hard to find chip.

Not much to worry about if you plan to use either the stock 030 or any third party accelerator.

Then there is the SuperBuster rev, if this is an stock 3000 most probably that it have a rev 07 SuperBuster, that means (yes, more) problems with DMA and ZIII, so problems with certain ZIII boards like the fastlane, this one is quite easy to get, a rev 9 or 11 superbuster should do the work ok

Nice system! Congrats. My 3000 is my favorite of all of them.

 

[mjnurney]

3.1 roms on the way.
the mobo has 12mb ram , this goes up to 16mb i believe? 8x512 zips
and then later a 060 or 040 for it.

I`d be lying if I said I wasnt jealous... very nice

If you want external drives you must remove the internal (socketed, I hope :blased termination packs and add an external terminator to the external connector.

Just disabling the HD termination will be not good.

Another option is finding a cable with external connector on one end and route this end to the back of the case.

With this second option you can keep the original termination pack and the switch you already have and simply use the external media of your choice.
