I had a request to install this MegaChip on a REV 5 Amiga 500 and take care of the 3.1 ROM kickstart socket mod as well while I had it. The process was fairly straight forward. I followed the original manual for the MegaChip for a REV 5 by cutting and relocation the JP2 jumper and then had to cut a single trace over near the trap door RAM header. You then need to attach a jumper wire from the board to pin 36 on Garry or pin 48 on the 68000 CPU socket. Once done I desoldered the original Agnus socket and replaced it with this newly made adapter board with 2MB and the 8375 Agnus on it directly to the motherboard. This will allow a 68000 socket accelerator like the Vampire 500 and others to fit over the Mega Chip. I am quite pleased with the final results. If you are interested in one of these you can pick one up over at Amibay following this link: http://www.amibay.com/showthread.php?101224-Megachip-for-A500-A2000-and-CDTV-(rj1307-project-Poland)
With the feedback I received from some members of the community its been decided that this will not move forward for now and is on hold for the foreseeable future.
Several of you have been asking what will the next replica project I take on be? Well I think a lot know the answer to this now, but let me share with you. It will be the 4000T! Things have been put into motion already with the same place I had help me get the 4000D boards completed. I have lots of data collected and turned over, a blank NOS board on it’s way to me from a friend and I have had some of the daughter board modules made so I can supply blanks for them to reverse and not need to take apart an assembled set.
The next phase of the project will be to get a quote from them on the cost of this. I will once again be on hand to help with all I can do which will lower the cost down in the same way as it did before. I will also be making a batch of boards again to sell off once complete to get the price per board as low as we can for the first of you interested in them, and finally it WILL all be posted open again on GitHub as a project for anyone to do with as they please, just as the previous one is.
Once I get a price quote and have an idea of what it will be you will all see the GoFundMe page go live. I am also going to start another PayPal account specifically for the project for those of you wanting to help with donations this way. Just understand that it will be difficult to show credit on the main page of who has made a donation this way. The solution I may do is to post weekly updates and list all of them by hand in that.
Thanks again for all of your continued support! I will be posting anything new as I get it in.
Hello from Sunny Florida! Yes I am on yet another work trip and away from home not doing retro hardware stuff. I guess having to do my real job must get in the way from time to time right??
Well today I bring you a great picture of one of my boards I sent out to my good friend John Hertell. He has done an old dead 4000 a great service by transplanting its parts to this nice newly made white PCB, complete with my logo on it!!! It does me proud to see these machines getting new life in the exact way I have intended them to live again through these boards!! Well done John and thanks for showing it off!
With things finally caught up again I can start to accept a selective amount of minor repairs, recaps, and upgrades again. Anything with severe corrosion and abuse will remain on hold for now. I just don’t have the time to deal with that. Recaps should go out within a few days of receiving them. Repairs will depend on the issue, but totally dead boards are not particularly desirable for me still. I do have several personal projects I would like to complete between things too.
Many of you may have seen my posting about the AmyITX I was putting together a few months ago. I am pleased to announce its now complete and working well. I will be showing her off this year at the Amiwest Amiga and Commodore show in Sacramento California October 11th – 14th. If you would like to learn more about the Amy then please visit the project page at http://www.amy-itx.com/ .
