Anyone heard of the Heron and MMU Remake?
Specifically this Heron RAM upgrade
The reason I was asking is because the blurb states there is a remake MMU coming that will allow for more than 4MB of ST RAM.

Interesting.
Back in the day, there was the Magnum 16Mb card: https://www.soundonsound.com/techniques ... um-st-card
Although, it didnt replace the MMU IIRC.

Re: Anyone heard of the Heron and MMU Remake?
There was an opensource 8MB AltRAM card (like the Magnum ST) discussed here long time ago.

Neither needed to replace the MMU.

Re: Anyone heard of the Heron and MMU Remake?
Wouldnt the inclusion of the (in development) MMU at least entertain the possibility of the extra ram being ST-RAM?
Re: Anyone heard of the Heron and MMU Remake?
Yes, if the MMU was changed to support a larger address range it would be ST-RAM not Alt-RAM
The Heron was launched on 23rd August 2024 and is as yet just a 4MB ST-RAM upgrade.
Lotharek is making/selling it but the designer appears to be called "Bartek Świderski"?

Re: Anyone heard of the Heron and MMU Remake?
I saw this this post on FB as well - Retro Lemon is selling it.
I'm curious about the extended ST RAM ranges, and how
it will eventually compare to something like the STorm-ST,
for example...
