I may not have searched hard enough but I am wondering about making a Cartridge with Editor Assembler GROM and an 8K battery ram with calendar and clock.

The 8K RAM could be easily written to and used to host CAMEL Forth.

Since the kernel is only 8K the battery RAM could be used to hold Forth in the cartridge but could be updated if need be very easily.

(I will have to cross-compile a slightly different version for this application but that's what we do this for isn't it?) 

 

The real time clock and calendar is just a nice addition to the system.

 

Would a mini-memory cartridge board allow this kind of thing?

 

Anybody know if such a board exists?

 

The chip I have used in the past is old (MK48T18)  but I see newer versions available like this:

Rings a bell I've seen something like that, but like you, a cursory search after reading your post didn't produce anything.

 

Other than the obvious 24/28 pin size difference if using an existing Mini-mem pcb/cart (arcadeshopper has adapter boards), I'd say it would be a fairly easy realization.

I'll keep searching and reply back if I find anything:

This is generally called a "supercart"

Thanks for the responses. I will look into the supercart idea.

Yes, I have one that was started 20 years ago, not finished yet, been in storage since then, that had a BCD switch to go between banks. could cram some stuff in there and was battery backed like a gram device. Since then, there have been a lot of improvements, by people like Ksarul.

 

Here is a link with some info, to get started.   http://www.mainbyte..../supercart.html

I did this with 2 additional groms that can be selected with a switch. You can choose:

Editor/Assembler

MiniMemory

Disk Manager

But most of the time I just left it on the EA grom.

I think I will buy a board and case from Arcadeshopper after I kill a few million more bugs. :-)
