Hi there,
I've been festering around Amiga web sites for years, reading posts and thinking about purchasing a classic system...I used to own a A2000 back in the 1980s. I have a non-responsive 1200 at home: The green light comes on, the hard drive spins a bit, but that's it. When I try to start it without the HD, the kickstart screen never shows up. Question: I purchased a set of 3.1 ROMS for it. If I remove the old chips and install the new ones, is there any possibility that this will destroy the new ROMS? (I will be wearing an anti-static wrist band during this surgery.) Thanks for your help/ideas. |

I wouldn't make any changes until you have sorted out the first problem, else you will get extremely confused.
How is your monitor connected ? More details please :-)

Hi,
The board was in working order when I purchased it. The monitor is an ordinary PC monitor. It's connected via a ... scandoubler flicker fixer? Well, it's a device made up of two small boards that sit on top of two chips on the 1200. I found an image of what I am talking about here: http://www.scuzz.org.uk/amiga/a_scuzz_jan05/a_scuzz_feb12_06.jpg This video arrangement seems responsive since the monitor shows the same background vertical lines that were also visible when the system worked. I've already disassembled the entire machine in an attempt to towerize it into an Elbox D-Box. Although I was careful, I may have overlooked something. Perhaps the problem is more serious. I may have fried the board with static. That's one of my fears. I may also have damaged it while trying to insert it into the D-Box. I had particular difficulty installing the FastATA 1200 MK-III from Elbox. Not only did this involve removing the ROM chips, but (I hate to reveal this) I also placed the original chips upside down on the FastATA board. If nothing works, I'll look for another 1200 on eBay. |

Don't forget to buy a anti-static wristband and use it to built your D-box up.

If you put the original ROMs back in upside down when installing the FastATA then it will most likely be them that are fried and once you replace them with new ROMs the Amiga will work again. Unless something else was also damaged at the same time.

I really hope that's all that's dammaged. I have all the A1200 pieces and Elbox add-ons waiting for the new ROMS, ready to build into a D-Box. Oh well, there's always Amiga Forever, but since I started this D-Box project, I want to see it finished and working.

It does sound like it may be worth trying the new ROMs then, but make sure you put them in the right way ;-)

Unplug everything from that board except the scandoubler/flickerfixer and the keyboard. Put your original roms back in.
Then plug your amiga into a regular tv using the composite port (the yellow one). It may not be the roms you see, it may be something else not quite connected right. Most important, Dont Panic. |
