In fairness, it's pretty hard to get empty film canisters anymore... ;)

You have to look in Aisle 3 next to the blank cassette tapes. Or ask a clerk to check behind the counter, where the pagers are on display.

Due to the DIN-like connector, I think this cartridge connects to the Kantronics Challenger unit,

and not to the MFJ-1224. This just should be a variant (?).

 

Find some more pics here:

yeah, and grafik.png.3b25d32f62c660a6409602014cfe37e6.png

Reliable seller though. I have bought from him may times in the past--and all of his items were exactly as described and very well packed.

I believe that is the same cartridge I just sold to him a couple months ago for about $40 that I got for $10

What is this thing???

Love how the item description says "...made for club members..." yet makes no mention of the club? Dallas area too.

Rich Gilbertson and I are recreating this module with the UberGROM - so it won't be unique for long.  :)

Still begs the question... What is it?  If you are recreating it, maybe you know what it is?  Thank you :)

Yep, we know exactly what it is.  It's kind of a proto Mini Memory.  The manual is here - but the source code attached is likely for a later version of the module (it wouldn't fit in a 4K GROM.)

 

In essence, it's the following:  4K of GROM and 2K of GRAM all in the G3 address space.  The lower 4K of G3 is GROM (which is all the routines you can use in BASIC) and the upper 2K is GRAM (where you can load data into, and run GPL from).  It works on a stock console, but can also use the 32K memory expansion and the disk controller if present.

 

It has two functions:

a) Three menu items on the selection screen to run GPL or assembly from the 2K GRAM space (we haven't tried these yet).  The third is to run assembly from the >6000 Cart ROM space (which this cart doesn't have - but the UberGROM could; I plan on testing this soon.)

b) BASIC calls to manipulate memory, read/write VDP, CPU RAM, read and write sectors on disk, etc.  

 

We do know that a lot of the GPL CALL routines are broken.  Rich Gilbertson has been looking at repairing them so that they actually work.  

 

So, really, it's not near as useful as say - it might have been before the Mini Memory and Editor Assembler were released, which I think was what this module's purpose was for.  We're working on fixing it to where it will work in an UberGROM (with the first use of the UberGROM's GRAM space).  

 

I'm hoping whomever buys this can produce high resolution scans of the PCB and dumps of the ROM so we can compare it to the two that Ksarul has.  I'm considering bidding on it to simply preserve it and possibly reproduce the PCB.

Thank you :)  Sounds like a fun project but not "exceptionally" useful in the end (if you have a mini-mem or ed/as - I have both.)  Also, since I'm a hobbyist (and not a collector,) not something I'd be interested in fighting over (considering the current bid.)

Not to drag the conversation too far off topic, but am sort of curious.... What is the limit (amount & location,) of RAM (GRAM, VRAM etc...) that can be placed in a cartridge?  I've often wondered....

One other useful tidbit: I'm pretty sure I still have a pair of the circuit cards used for this one as bare boards. It uses a standard TI EGROM circuit card. Pretty much any true prototype TI cartridge was built on variations of this circuit card before it was committed to silicon in the form of GROM chips.
