MOMBO to Burner

"Well ... rombo, mombo, mumbo, jumbo!"
NOTE (14-Mar-08) The photos and methods below are the old way. The new chips can no longer be burned while on the MOMBO board. Due to this, in 2007 I had to purchase a new ROM burner and SOIC adaptor in order to burn the EPROMs. Once burned, I then solder the EPROM onto the MOMBO and am good to go. Also, EME Systems now supplies me the MOMBO boards raw. They must be trimmed. It's a simple task using a drum sander. Simply sand the MOMBO down to the trim-guides. I will soon add photos and process to this file for this new method. And last but not least, I have reduced the cost of the raw MOMBO boards -- now called MOMBO Lite -- to $10 vs. the old price for EPROM mounted on a trimed MOMBO of $25. It seems more fair to me. -Rick-

The Model 100, 102 and 200 have a built-in Option ROM socket. The files below are Intel HEX file images of available ROMware. To use one of these files, you must copy that file into a 27C256 EPROM, using a simple terminal program at 1200 baud to an EPROM burner with the 27C256 EPROM inserted. We use the A.R.T. 1, here at Club 100.
Once burned, you must place the EPROM into a device that will remap the pins of the EPROM to the pins of the Option ROM socket in the Model "T" computers. For years, Club 100 used the EME Systems ROMBO carrier. The material used to produce the ROMBO carriers is no longer available, so in a joint venture in mid-2002, EME System designed a new Option ROM carrier for Club 100. That carrier was called the ROMBO/MOMBO. This was shorted to MOMBO.
The photos shown are of the MOMBO, the burner adaptor, the adaptor with a MOMBO inserted ready to burn, and the burned MOMBO finished off and inserted into the Option ROM socket in a Model 102. The green ribbon is taped to the back of the MOMBO to be able to remove the MOMBO, along with a tiny spacer used to set the MOMBO at the correct height in the Option ROM socket.
Last but not least: to access the ROMware you must call it (one time) from within BASIC. The standard call for a Model 100/102 is call 63012. The Model 200 is call 61167,2. The Traveling Software ROMs are called in a Model 100/102 with call 63013,1, and in the Model 200 with call 61167,2.
The NEC PC8201A does not need a MOMBO, just burn the NEC Intel HEX file into a 27C256 EPROM, insert the EPROM directly into Option ROM socket #2, and call it with poke 63911,1:exec 62394.
GET MOMBO Lites FROM CLUB 100 Club 100 sells MOMBO Lites for the seasoned EE and do-it-yourselfer who wish to burn their own ROMware. See Catalog for details.
MOMBOS Lite without the PROM attached Some people have asked if they could buy MOMBOs without the PROM. The answer is, "it all depends." The MOMBO does not use the normal EPROM DIP package. The inventor, Dr. Tracy Allen, EME Systems, Berkeley, CA, writes, "Any speed of chip will do. Normally available from Digikey is the Atmel AT27C256R-70RC, but the AT27C256R-90RC will also do. The important thing is the package, which is a gull-wing SOIC. (shown by the "RC" at the end)." So, it all depends on if you can solder the gull-wing SOIC. I keep MOMBO Lites in stock. Order as many as you wish.

Note: The TS-DOS ROM includes a cold start recovery routine. Should you have a TS-DOS ROM in your Model 100/102 or 200 and you experience a cold start (i.e., the menu goes back to 1900 and all your files are gone) go into BASIC and do a call 63013,0 for a Model 100/102, or call 921,146 for a Model 200, and for a TS-DOS ROM in an NEC PC8201A it's POKE 63911,146:EXEC 1124.
