UberGROM as a Mini Memory with more memory -- possible?

[Omega-TI]

I have a question, would it be possible to turn an UberGROM into a Mini Memory module and use the 15K of GRAM as usable space?

[Tursi]

The MiniMemory is software in GROM and a 4k RAM chip. The RAM is intended mostly for loading assembly language code. Since GROM memory space on the TI can't run assembly code, it could not be used for that.

 

We'd need a faster processor to be able to emulate RAM. It's conceivably possible, just not with the 8MHz AVR.

Thanks for the explanation Tursi.

Hmm maybe people do not understand that GROM/GRAM can move Assembly Code

into FAST RAM and run it

or into 32K and run it

or into 6K of Cartridge RAM and run it.

 

Many either do not understand GROM/GRAM and attempt to make it look useless, most that say this are Assembly Language people.

 

I do not understand why people act like this?

From GRAM/GROM Cartridge you could fill the entire 32K and have 8K of VDP GRAPHIC left over.

This would be many many times faster then Disk or Hard Drive or RS232 or even some RAMDISK.

Yes, Rich, but that's not a Minimemory anymore... it's expected in the MiniMemory scenario that the only fast RAM is scratchpad.

 

You could do a Playground-style approach from GPL, and that'd be interesting, but it's not related to the question

 

That's why I "act like this".

I didn't mean to start anything here. I know many of the TI-gods here got their start with the Mini-Memory and it's Line by Line Assembler environment, which I believe, but I may be wrong, gave them instant feedback and helped in the process of learning of assembly.

 

I was thinking that if a modern alternative could perform functionally identical (except for program storage) it might be nice. I was also thinking the UberGROM might be able to contain other useful goodies for extended capabilities as well and that might attract more users.

 

Compatibility, Extended Functions, Lower Cost, New -- just my brain working overtime again. My apologies.

hmm, I think it is or was a good idea. Even it is the worst idea ever, that´s what´s bringing the show on....bringing more ideas.

bringing other people to more ideas. so, why apology?

I got the Minimemory but that's because it was difficult to get 32k without a PEB. These days, it's pretty easy - either via a modded console, a NanoPEB, buying the system complete, etc. In all of those cases, the Editor/Assembler is a better bet. And all of that PLUS the instant gratification is easier to come by (not to mention learn) via emulation where you can trivially single-step and observe the results of each instruction in real time.

 

So... I don't think a new MiniMemory helps that much.

 

And nothing is started, Rich and I get each other these days!
