Greetings,
I am a new member of Amiga.org, but really I am not newer to the Retro computing world...
During these past times I was developing a workaround in order to use the remaining memory chips from an accelerated Atari ST project. This project requires a change on installed memory due to memory acceses are totally upgraded, new memory chips were used.
Now, these memory chips are used for an Amiga 500 chip RAM expansion, its a 512 KB trapdoor memory expansion.
The results are these:

and the working results are these:

I manufactured several of these, available at supermarket; these memory modules are hand manufactured at my home in Spain (http://www.lemonamiga.com/forum/images/smiles/icon_smile.gif) and tested prior to be sent. These are sent on tracked packages also for international destinations.
The module includes short-circuit protection resistances and enable/disable switch.

welcome aboard :)
nice to see new hardware for a fair price.
btw, you mean fast ram not chip ?

Chip in the A500+, fast in a stock A500 (unless it's been appropriately modded to support additional chip in the trapdoor slot - as they should be, IMHO). ;)

It's either chip or slow (aka Ranger) mem.
As slow as chip but can't be accessed from the chips.
On the other some games will only work with slow mem available.

Very nice !
Just refurbished my 500, next time will be tweaking that one, maybe with your memory expansion ?

I hope this!
You will enjoy from a carefully "hand-crafted" RAM expansion :)
