Re: [M100] REX replaces internal RAM?

[Gregory McGill]

Rex = no ram. just backups of whatever is in ram to a nvram storage
I have ram chips in stock.. so you can expand to 32k..

the QUAD used to be available that replaced internal ram but it's no longer
being made

Chris, to John’s point also, if you were to get a REX but with only 8K RAM
in your M100, the REX would in effect be quite underutilized.  REX is an
excellent way of backing up RAM into selectable banks - like having
multiple computers in one.  However, if you only have 8K RAM, each REX bank
will likewise only back up 8K of content.  To truly get the most out of
REX, you may want to invest in more RAM first.

I think you’d still be able to have multiple option ROMs on your REX, and
each of those could take up a full 32K REX bank, but your maximum data
memory while using one of those option ROM programs would still only be 8K.

Best wishes,
Anthony

 Thanks John - That's what I was getting at but did not articulate it clearly.

 Chris -- no, a normal rex does not replace your internal RAM. If you have a 8k 
unit now you still will after installation.

I got a REX last week from Arcadeshopper. It came really quick too with
excellent service. Now I just gotta get used to the "REXmgr"! Now my old
NADsbox will get a real workout.

Cheers

I think Arcadeshopper has both the RTEX and 8K RAM modules available. 
https://www.arcadeshopper.com/wp/?page_id=11#!/100-102-200/c/28313042/offset=0 

 =nameAsc . It is my understanding that the REX copies all 32K or RAM to 
flash and back, i.e. backs up to RAM and restores it when you switch banks.

Does a REX completely replace/supplant the internal ram?

 

If I have an old Model T with 8k and insert a REX does the computer run 
completely via REX?

 

Are there Rex boards available?
