I've got good news and bad news.
The good news:
Searching through my box of sharp PC manuals turned up the CE-160 Manual.
The Bad News:
The manual states:
"The CE-160 is a module that can write any program by using the CE-165 exclusive writer. However, no program can be written in CE-160 by using the PC-1500."
"When the CE-160 is connected to the PC-1500, all the programs, data, and the reserved contents previously stored in the PC-1500 cannot be used. Therefore, should be need these, make sure to record them on the tape before connecting the CE-160."
"Any program writen in the CE-160 cannot be either displayed or printed using either the LIST or LLIST instructions. No programs can be recorded on the tape using the CSAVE instruction."
It would appear that even though these are ram modules, they act like pre-loaded rom modules. The big difference is that after 3-5 years, the battery goes dead and all contents are lost. Sort of like self-destructing programs. They say to return module to the orginal place of purchase to have battery replaced and re-program module with the programs.
Has any one ever heard of or seen the CE-165 exclusive writer? Haven't been able to find referece on the web about it.
Very interesting module. Make's me wonder what the thinking was that went into developing it.
Looks like I have a nice display item, but not of much practicl use.
