New manufactured Amiga 500 and 500+ chip RAM expansion
« on: May 23, 2018, 12:39:21 PM »
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:









For Amiga 500+





For Amiga 500

















I manufactured several of these, available at supermarket; these memory modules are hand manufactured at my home in Spain     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.

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.
1. Make an announcment.
2. Wait a while.
3. Check if it can actually be done.
4. Wait for someone else to do it.
5. Start working on it while giving out hillarious progress-reports.
6. Deny that you have ever announced it
7. Blame someone else

I hope this!  

You will enjoy from a carefully "hand-crafted" RAM expansion :)
