A500+ Program Failed 8000 0003
 

Hi, i recently bought 2 Amiga 500+'s off of ebay, they were labelled as for spares or repairs but i thought i could fix them up and have at least 1 working A500+, i have hit a brick wall with this error though, i can load workbench ver 1.3.2 fine, but when i try and load a game it throws up that error :S, could this be a rom error? ive had the case open and checked all the chips and pushed them down, the only thing i did notice when i had the case open was that the battery had leaked slightly but nothing drastic and that someone had appeared to have modified the mobo in some way, a diode had been desoldered from 1 spot and soldered onto the pin of a resistor :S. any help on fixing theese machines would be appreciated.
Thank you very much.

I believe that that guru is usually caused by bad memory in a system...

Not 100% sure though

What program are you trying to run?

8000 0003 normally indicates the opcode contains an illegal address?

Common Causes
Data Corruption due to bad RAM.
Trying to access 32-bit RAM on a 24-bit processor.
KS2.04 incompatibility.

Just be sure to test a game that doesn't normally fail on A500+. Quite a few OCS/ECS games failed on A500+.

its any game i try to load
Wanted for instance.

BinoX you say Bad memory? the ram? is this easily fixed?

i feel like a fool now, thought i could repair theese consoles easily :(

EDIT: Ok some games work, another problem has arose though, Joystick 1 port doesnt appear to work :S, things just go from bad to worse hehe.

So that means, you can't use the mouse when you load the Workbench?

I use Joystick port 2 for the mouse in work bench.

You sure? WB uses port 1 (where the mouse is normally plugged into).

well i swapped the CIA? chips out with the other machine i purchased and now both ports work fine, could it just be a game compatibility issue that causes this error, some games work fine others crash :S. if so is there a way to check and see which games will and wont work. thanks .

It might help if you list what games don't work and what happens when you try to load them.

Wanted: Program Failed 8000 0003
Renaissance: same error
Spy vs Spy: Just lines of code, looks like hex?
Wanted and Renaissance are copies of the original games, could this be related?
Aztec Challenge(Original copy): Worked fine

Well if some work and others don't then it's likely that certain games are incompatible with Kickstart 2.04... do you have a degrader (such as ReloKick)? Try loading that then running the games that don't work.

Will i need something like catweasel to write ReloKick to a floppy?

A serial cable+workbench disk+AmigaExplorer

Trouble is, ive only got workbench version 1.3 which doesnt support crossdos so i have no way of getting files onto the amiga at all.

Ive been reading about theese leaky batteries on the motherboards of the amigas, mine appears to have leaked a lil bit and theres a blue/green corrosion on some pins? should i carefully clean this off and remove the offending battery?

Yes, be very careful about leaking batteries. You should check the motherboard throughly to make sure that the acid has not eaten anything. Since most of the custom chips are socketed, problems due to leakage may be intermittent and you may need to clean the chips and sockets to get a more reliable connection. Be aware that these devices are very sensitive to static, so you should ground yourself before you do any work on it.

As far as I remember it is possible to run a similar tool to CrossDOS called MultiDOS in Workbench 1.3, but it can be a pain if you only have one floppy drive and no harddrive. The tool is available on Aminet, but read the included README file as the software has some limitations under WB1.3.


Hope that helps,

You dont need crossdos... you just need Amiga Explorer and a serial cable...

There is a program on ALL workbench disks that can be used to install the software from the PC to the Amiga and then the Amiga floppy drive becomes a slave to the PC... you drag the ADF onto AmigaExplorer on the PC and it writes it.

Wow, ok that sounds like a brill option, ill go with the serial cable, i need a null modem cable right? and ill desolder that battery now and clean the motherboard, yeah some of the socketed chips have blue dust on their pins?
Oh and i do have 2 floppy drives for this amiga if it helps, the internal and 1 external one.
