Advice on best A1200 accelerator

[Snoozy]

i tried that earlier :confused:
 
should i try spraying compressed air around the connectors?

[Snoozy]

The strange thing is the card is actually getting slightly warm if i leave it installed and the computer running for a while???
 
:roflmao:no thanks gajan i'm having enough problems with this card never mind buying more probs!!

[Snoozy]

By the sounds of things i need to be altering my Start Sequence in order for the computer to recognise the card (I think this comes back to having rom 3.0?)
 
How do i get into the Start Sequence (SS) to edit it? And then do i type:
 
C:ACATune - maprom Devs ROM3.0 -cache on -burst on>NIL:
 
is this right?? Do i save this into the start sequence somehow?
 
I need a computer wizard or wizardess to advise!

[Snoozy]

But are you using rom 3.1? As i think rom 3.1 auto detects the ACA card, i gather rom 3.0 does not auto detect the card? so do i need to install rom 3.1 into the devs folder and change the SS command line to ROM3.1 hmmmm

[Snoozy]

In that case i think i am going to have to remove the metal shielding and have a clean up of the motherboard !
 
Does all the metal shielding come away in one large piece, it seems slighlty annoying to remove :angry:

[Snoozy]

Thanks donut king i have tried bending back the metal shield but this has made no difference either....there is just no way this card is being recognised by my amiga (firmly pushed in and its a blank or green screen, move back a touch and it loads wb but no card recognised.
 
I think i am defeated and will ask in my local retro computer shop if they can install the accelerator for me..

Hi yep soz i should have posted that way earlier :afro:
 
my mobo is 2B
 
 
 
what a saga

[Snoozy]

Ok so it seems i need timing fixes for my 2B mobo? :hammer:
 
Who can help me with this?
 
(I have no reason to believe there are any probs with the card and i have handled it with due care and it still looks immaculate)
 
How about if i buy and install the 3.1 rom chips, will this solve the problem??

[Snoozy]

I will see about taking a photo in the next couple of days..
 
It seems others have had the same probs with this ...
"
HOORAH!!!! E123C & E125C removed this morning and A1200 has been running for over 4 hours with ZERO lock-ups! Thanks FOL, thanks AmigaKit, thanks Jens!

I am one happy bunny." Thats a quote from here http://eab.abime.net/showthread.php?t=55059&highlight=timing&page=38
 
But my question is did these people have their card work (even momentarily) as mine doesn't even appear to register with the a1200

[Snoozy]

:roflmao:no i was quoting some one else!!!!!!!
 
Mine is still as dead as a do-do!!!!!
 
Help!!!
 
I will try what bond has recommended in the meantime, maybe my a1200 needs to go in intensive care?

[Snoozy]

Ok  guys i thought i'd let you know straight away that i have taken my a1200 completely apart and finally the metal shielding is off (yes novacoder i hope to see it melted down!) and the card is WORKING!
 
So i think one of my main problems was getting the card fully engaged on the a1200 board slot - this is pretty difficult to do (especially if you are being gentle with the card) whilst the mobo is still screwed down. Once u got the mobo in one hand and the card in the other its so much easier - i had the card fully enaged and initially..nothing..i switched off and move back a touch and suddenely the menu bar at the top of wb says 55,000,000 memory:)
 
Bond thank you your suggestion was most logical and correct so it seems..
 
Stability tests to follow..

[Snoozy]

Hells bells i hope i don't have to do any of those fixes :confused:
 
So far the a1200 has been up and running lords of the realm aga for nearly 2 hours with no probs.
 
What i would say is this: there doesn't seem much of a chance of installing the aca1230 without removing the mobo and physically pushing the two together (significant amount of gentle force required!) There are plastic runners on the a1200 plastic casing near where the card sits that protrude and prevent proper fitting if the mobo remains screwed into the lower outer 1200 white casing. I used some industrial strength (fiskar) scissor to chop away nearly all of the white plastic runner of the a1200 casing and then the aca1230 card JUST fits snuggly. I think i was on a hiding to nothing with fitting this card and trying to prevent the card touching metal shields etc without actually chopping and removing the plastic. The A1200 survived the surgery
 
Anyway now that the upper metal shield has deparated the CF card is plugged in and laying freely on some chips !! Is this safe and stable for the system, it worries me slightly..

[Snoozy]

Ah thanks novacoder i'm glad it wasn't just me that had to do that fix...i think if i had tried installing the card with those plastic runners in place i would need to have been He-man and would have eventually risked damaging the card as it abutted the runners and may have ended up cracked or snapped!! When your pushing tha card in you are pushing it from the edge with the least components on the card (where the board feels more flimsy) so it doesn't instill much conifdence in pushing really firmly on it
 
Maybe portarinos has a different mobo or revised outer a1200 casing?
 
I hope my saga may help other ppl (esp beginners) when they come to install their aca card in the a1200 :roflmao:

[Snoozy]

hi guys i'm just coming to the final stage of installing my aca card, i've edited my wb start up sequence to this:
 
C:ACATune - maprom Devs kick31 -cache on -burst on>NIL:
 
and this replaced my previous command line which was something like WBPatch <> NIL:
 
so now when my 1200 boots up it doesn't quite boot up properly first time, but boots up properly if i do a soft reset. Is this right? Is there any way i can get it to boot up properly on first attempt? Maybe i shouldn't have deleted the initail command line and added the above directly underneath it?!
 
So High Priests and High Priestess's of ACA can you please advise?

[Snoozy]

Oh no what have I done!
Can u give me ur s:start up sequence!

[Snoozy]

Hi guys,
 
i need a little more help with my s:start up. I have edited s:start up by inputting C:ACATune..etc command line into the first line of my s:startup and my aca1230 card is recognised fine once wb loads..problem is wb doesn't load from cold start..it starts up but the screen goes blank (as if going into a reset mode) and then the system hangs on black screen. So i then do a soft reset and it works normally with ACA card recognised. Anyone know what is happening here? FYI my s:startup is very standard apart from the ACATune line i inserted at the beginning.
 
Another question! My PCMCIA port recognises my 2mb pcmcia ram card but no longer recognises my PCMCIA CF adaptor :cry:
 
Why is my 1200 so tempermental :smack:
