A2000 mk2. the big bang

Paul_s · 13 December 2011, 23:48

A year or so ago I sold off a 2000

. It was an early Rev 4.3 and worked flawlessy.

So, I've missed owning a 2000 since, saw one on here for sale so had to have her. I really like the 2000, they are built like a tank (literally), well made and easy to work with compared to a 3000/4000 (excluding technical limitations

)

So the new one is a Rev 6.2 (last of the 'OCS' model before ECS was fully implemented on the 2000 line. She came with a GVP HC+8 (nice piece of kit) and has 2MB on board (I think).

Done a bit of work on her tonight - mainly cleaning and chassis bending.

Bit of greenery courtesy of the battery (had been removed when I got it) but will soak CPU and surrounding areas with some lemons when I come to fully cleaning the board...

Noticed the case was bent - a common thing with 2000's and puts stress on the mother board bending it upwards

. The only way to 'fix' this is to pull everything out - place case on floor and step on inside

That's better

More cleaning this weekend methinks. Need to check one of the disk drives over too as it's reporting errors when reading a disk (works fine in the other one)... but with my OCD for cleaning, I'll clean everything

The LED holder on the front needs hot gluing in as the tabs that secure to the chassis have been broken at some point in its life.

Still deciding on whether to goto town with this Amiga and pimp her out with an insane accelerator... my purchasing plans could bail out the Euro...

Good start, Paul!

I'm looking forward to see how it progresses.

Nice work mate

How about a GVP 040 Combo & a PicassoII?

If you can find one a Thylacine USB would be good too

kire_online · 14 December 2011, 03:35

Nice work, didn't think to check for a bent chasis on my A2000, I'll take a look this weekend.

and there was me expecting an monty python type picture

nice to hear you got an A2000 again

Paul_s · 14 December 2011, 23:43

I was highly tempted to take a picture of me standing inside it... must admit

Weird, GVP jumpers for the HC+8 card were set to 2MB but this thing has 8 x 1MB 30-pin simms. Will try it out over weekend and see what's what. Also has a nice surprise with a Guru ROM (v6.10).

Steve, I am tempted with a 040 but half of me is saying to keep it stock'ish and revert to KS 1.3... I was thinking of a 060 in there but it ain't cheap

Paul_s · 18 December 2011, 15:25

Not much to report on.

Today I removed all IC's; cleaned and reseated and added a bit of lemon juice around the battery area - got all the green battery leakage off now and is in very good condition around that area.

The 68000 was the main victim, I've soaked this in lemon juice but decided to purchase a fresh 68000 anyway.

Waiting on a new 1.3 Kickstart ROM as well to finish the main board off.

Just the Floppy drives to sort and cleaning the PSU out so this one has been an easy one... still not sure about the insane upgrades (yet

)

Nice A2000 there.

Cheers chap

Gah, well, I ordered a new CPU which turned out not to be so new. The pins were bent really bad (one broken) so I've not used it and the old CPU now refuses to work (2000 boots up with just a white screen = CPU failure

I guess soaking it in lemon juice sent it to the big CPU graveyard in the sky - it hadn't been used since the 13th dec so was pretty bone dry!... hmmm). So, another 68000 on order - this time a NOS

Here's some advice - A2000 FDD mounting is a pain in the arse to get right, I need to reseat again as still not right after cleaning out both drives (both were dirty ~ so hopefully the one on the right which was throwing up read errors is cured now).

PSU cleaning went well, just a bit of dust. Kickstart 1.3 is in there too (thanks Amigakit

)

No pics yet but will do some when I get the 68000 sorted. Still undecided about accelerators... want to make sure this CPU problem is sorted before spending more £££. Oh, and I have a 2320 on the way here too

orange · 11 January 2012, 20:19

are you sure its CPU and not a broken trace? have you tried it in A500 or similar?

The computer was working fine beforehand - I did soak the CPU in some lemon juice though (the only chip I did that with due to the corrison on the legs). I could try it on my 500 I have but it's all wrapped up! If the new CPU doesn't arrive by weekend I'll dig the 500 out and do some testing

Matt020 · 23 January 2012, 15:01

Did the CPU arrive? Is she alive?

Erm, that probably killed it...at least once you fired it up.

I think there is at least one spare here if you need it though

PZ.

Paul_s · 05 February 2012, 09:58

Nope, the CPU is working fine as I transferred all the A2000 custom chips to a working 500 as a test.

I've since found that one of the legs on the Angus socket has corroded and broken off! This means a new socket will be needed - so pretty sure the 68000 socket is OK. But would probably get it replaced anyway.

Now I need to find someone who can repair her or buy a hot air workstation, Amigakit don't seem that interested - no reply to support ticket

cosmicfrog · 05 February 2012, 12:38

try Hicky over on amibay he did wonders for My A4000 Mobo, still can`t get over how clean it is

Amiga1992 · 05 February 2012, 13:31

d0pefish seems to be pretty dedicated too, I am sending my A600 to him soon.

Paul_s · 05 February 2012, 14:07

I've PM'd d0pefish this morning so hopefully he can sort her out

d0pefish · 06 February 2012, 21:44

Ahhh - so this is the A2000!

I really hope I can get this sorted for you mate. I was just on my way to PMing you again

Sorry paul, I have been so busy over the last week or so.
I was awaiting another reply from you as you were trying some things first.

Paul_s · 07 April 2012, 11:54

Ah no worries, got her up and running now

There's more info/diary here of what d0pefish did (turned out to be a duff Angus socket and he replaced the CPU socket as well for good measure!)

http://www.amibay.com/showthread.php?t=25862

Oh, and one of the power lines for the RGB was toasted but I managed to get that sorted easily enough.
