The Amiga 1000 Chip RAM situation in 2021+
Howdy,
The amount of Amigas I have in my house is counted in double digits but only recently did I manage to get hold of a long sought after A1000. There are some nice solutions for FastRAM out there and also full accelerators like the "Classic 520" which can be preloaded with kickstart etc.. Also, as mentioned in another thread, PiStorm on the A1000 is also a thing.. Ive seen people use an ACA500+ but Inividual Comp seems to advise against it. So.. then what about the chip RAM situation. Fortunately, my machine has the 256k in the front.. But going beyond 512k chipram in A1000 used to be problematic.. from day 1. I'm only finding old info about stuff like the rejuvenator board, Phoenix board.. stuff that's just stupid rare etc.. But hey its 2021 now, and I'm trying to read up on what out there for the original Amiga. (Are there any Agnus adapter boards and other hacks that turn fastram into chipram (Like the ACA500+ does if you have the right Agnus)) If someone could suggest a few interesting products or projects (if they exist) that would be great. :great |
I envy you, I never managed to even touch an A1000, let alone use or own one. To me, it's still kind of the holy grail of Amiga's :)
Sadly, I don't know of any projects for the A1000 that do what you want. However, there is one small detail I'd like to point out. Quote:
Well, at least not at present - never say never and all that :) Hope you find a solution for your A1000 though! |
I thought someone was working on recreating the Rejuvenator with modern components?
|
Sadly there is no solution for this at all but yes Amigalove.com is supposedly working on a rejuvenator resurrection
|
There's always the GBA-1000.

Go to Jens Schonfeld’s forum on his possible plans for the A1000
https://forum.icomp.de/index.php?thr...-aca500-ace1k/ Jens: I was tinkering a little with a real 2MB Agnus on the A1000, but due to the limited quantity of chips available, I Have dropped this idea. It will probably be an Agnus-implementation in an FPGA - some time next year. Sept. 2019 |
I think our best chance is that new Rejuvenator board, if it ever materializes.
I am using the ACA500+ on my 1000 as well, worls like a charm. I'd love to buy an upright ACA1000 though, that would hopefully not stand out on the right side like a sore thumb.. ;) |

https://github.com/psurply/ReGAL So it seems this would be THE upgrade to get for all A1000 lovers out there. So let us hope this goes well.. But if it fails, not sure if there is an obvious plan B (for chip ram) right now..? |

Btw, in case those interested still managed to miss this one..
They did it! The Rejuvinator is fully reverse engineered! Upcoming tweaks to the design will most likely allow for less rare Fat Agnus versions as that is currently a real issue... (Also, the Video port is probably another thing that will be swapped for something more useful). https://youtu.be/41q0jgGaO-c |

But yea, not much joy for the rest from that valiant effort. Seems PAL machine owners will have to decide between modern trickery that basically replaces most of the A1000 (PiStorm, Vampire, A1100 motherboard etc) or keeping it more genuine and accept the chipRAM limitations ("Classic 520", ACA500+). |

Perhaps it was different in the continent. |
Same here, got a daughter board one.
|
At least 50% of mine are without the daughter board.

So us Munich folks call our city like that sometimes in jest as well. Would have invited you to our local Amiga meet ups if you were living here. |
