Just bought a SupraDrive 500XP
And I already love this sweet peace of hardware, even though it doesn't have a hard disk (yet), and only got 2MB of ram - And that leads up to my actual question
![]() I would love to fill it all up, with the total of 8MB ram, but after hours of researching, I'm only more confused. ![]() I know it has to be 1Mx4 DRAM chips, but as far as I can see, there's like a bunch of different variants, all with different specs and prices. Can you please help? Last edited by G00dY; 18 March 2014 at 16:23. |

yep.
i modified mine to use memory from a 8mb simm module.its dirt cheap if your any good at soldering. the expensive route is 1Mx4 DRAM ic's in dil package's,any will work between 100 and 60ns(16 ic's for 8mb) if you can get them,any on this list in a 20 pin dil package: http://www.amiga-stuff.com/hardware/1mx4-dram.html Last edited by roy bates; 18 March 2014 at 18:23. |

no problem,if you want pictures of my modification i will post them here for you to look at.
![]() i desoldered the ic's from this: and soldered them to round pin dil sockets so i could just plug them in like this: Last edited by roy bates; 19 March 2014 at 12:54. |

Oh my, this looks amazing, a very nice modification indeed
![]() I can only dream of ever accomplish something like that ![]() I'm so impressed how "simple" the Amiga actually is, it's astonishing... |

Roy! You blow me away with all your skills... brilliant stuff!
EDIT: This has given me a really good way of fixing a poor butchered c64 and its hacked up character rom! The dam thing was cut and the re-soldered onto legs. The whole thing was a nightmare that even I could not look at, proper ebay hacked up job. So the plan could be, round sil sockets with the chip carefully placed on top like the ram you did. I will solder it right or not at all. Hopefully it survived the torture it went through by the previous owner. |

@roy bates - the mod looks great. I presume you had SOJ variety? The link on: http://www.amiga-stuff.com/hardware/1mx4-dram.html I presume any of the chips could be used? I'm just wondering what version is 'plug and play' without modifications if you know the link to the 'proper RAM' needed to upgrade? |
