It looks like all of his posts have been deleted. This is silly. If the guy is making an effort to play nice, then let him.

Point is that he in the past had several chances to redeem himself, but he always got back to the old Doomy ways. I guess he p-off too many people.

What I don't like is deleting his messages, but also messages from other people. That is censorship like used in China  :-o Even the site where I hang around the most doesn't do that, and they are VERY strict (try asking a question that can be looked up @ google and your topic gets closed for example)

I agree with the toilet guy a little ways up this thread - it looks like your speed is all due to your fastram and we're not seeing the CPU running at 14.4 mhz.  I'm assuming that the omega accelerator performs this function.

Can it get you up to about 140% - 150% normal speed when active?  That would be a really nice bang for the buck!

At the moment it's running standard with only the memory boards connected.
I'm going to try the Omega 'accelerator' and post the difference (if any) it makes, then when my PLCC Remover turns up, I'll replace the Agnus 2 Meg Board and post the results. There isn't physically any room for both to whichever provides the best improvement will stay in.
My moneys on the Agnus chip, but I've a few days wait before I  can get anywhere with that.

Ho Hum, Just went to test out the Omega Speed Up board, and the Agnus Chip looks like it's decided to take a swan dive.
Just before I was going to install the Omega board, thought I'd power her up to check everything was A-OK.
It wasn't. :boohoo: Green screen indicating Chip RAM failure!
The Dimensions preclude fitting the Omega Board and the Agnus Chip board at the same time which is a shame, so until I can get my hands on another 1 Meg Agnus chip I can't test the Omega board to see what it can do :-(  
Off to look for one of these now.

are you sure the megachip was seated properly?  jumper clip attached?

I had two 500s give me the green screen before I realized they had chip seating problems and given you took the thing out and had another agnus in there I'm wondering if things might just be a little loose...???

Its the original Agnus chip that I replaced the 2 Meg board with when I was originally having problems.
That may be part of the problem, I've had the 2000 open and made sure the chip is seated firmly and it seems OK. I'm waiting on a PLCC Extraction tool to turn up so that I can replace it safely and ensure it's actually that, it may just take a few days.
I'm reluctant to try to prise it out and thus damage the socket.

I think I remember having done it both ways and as long as you're careful it's ok...but waiting won't hurt.

I've extracted many of these chips, and I never have problems EXCEPT with A2000 Agnus's.  For some reason, these sockets are extremely brittle, and break with or without the tool.

PHEW!

I'm glad I waited for the chip puller to arrive, It popped the Agnus out straight away with no effort! I reseated the chip and, BINGO, she lives again! :-D



Now I can finally get started on testing the 'accelerator'/ Agnus chip RAM boards to see what speed bonus (if any) they produce. It'd be nice to get the boot up time to less than 30 secs!

Will post results when I get the chance.

 If you want to be on the secure side of things, put some rubber bellow the Agnus.

 It dives into the socket regularly, the rubber prevent it to happen.

I'm a little surprised no one has mentions this (maybe it was in the missing messages?) but you really should add a real accelerator! I have an A2000 that I have used for years, with no troubles. I used a GVP G-Force 030 that was a great board because it would allow any game to play, yet added power to graphics prgs, animations, DTP, or what ever. They can still be picked up without taking out a second mortgage, and help with overall power AND adding extra RAM.
The Accelerator allows running 3.1/3.5/3.9 OS too.
I am just now upgrading to a G-Force 040, so I'll see first hand how compatibility suffers (or not?).
Good luck with your machine...
