Hi everyone


Universal Grom/Rom Module


I have been trying to track down info on this PCB, but no luck here on previous threads or WHTECH about multi-carts, it has similarities to the Super Extended Basic cartridge around the Grom section of the PCB.


I am hoping that the wiser :)  people can dig deep into their memory's and illuminate this Boards history.


Any info would be a plus.

I have a pair of these boards. So far as I know, the PALs necessary to use them have never surfaced, unfortunately.

Could the PAL equations be reverse engineered? Or maybe WHT could supply them.

Thanks for the info  KSARUL, at least i now know that the 16V8 refers to programmable PALs.  the Universal Cartridge Board has EXCEL DS, 94V-0, 07-94 on the Reverse


i found this in 


 Micropendium  1994/02
RXB in module form
Now you don't need a GRAM KRACKER to enjoy this POWERFUL version of TI's Extended BASIC. 
WHT has engineered an inexpensive module to hold RXB, includes disk and Manual.
Has anyone got  this cartridge ? or Photos internally?

If you have a FinalGROM cart, you can download it for free.

Thanks for the info --- Ω -- regarding RXB, at the moment i am concentrating on the history of this board .


I found this also from Micopendium 1994/03



A Cartridge using generic EPROMs for any number of programs, similar to the PGRAM produced by the late John Guion,


is available from Don O'neil of Western Horizon Technologies " for a modest Fee"



I have looked in various Cartridge lists produced in other threads here,  but WHT is not mentioned.


Does the above description of a cartridge ring any bells with anyone ?

Here is another  snipet of info, hopefully this will jog a few memories


A bit more info
micopendium 1994/10
Scheduled for release in late 1994 (pending completion of 20 pre-sales orders ) is the latest version of Rich Gilbertson's RXB, Version 6.
According to O'Neil  (abbreviated slightly)
" Rich has painstakingly hand entered all the original TI Extended BASIC source code from printouts he aquired " 
"Gilbertson has cleaned up and sped up much of TI's XB code and because of the larger space in the available in the WHT Module and GRAM Emulator devices etc...
