[Yaesu] FT890 PROM

[Bill Aycock]

The "readme" file for FTManager tells me that my FT890 needs to have th
"latest" PROM, (1.3), in order to work with FTManager.  My 890 has v 1.21.
I have a couple of questions that I hope someone will be able to help with.

1. what is the difference between v 1.21 and v 1.3?
2. will FTManager REALLY not work with 1.21?
3. can I upgrade or replace the PROM to a later version?
4. If so, how and how much?
5. which board is the PROM on?(I have the Technical supplement, but it has
no index)

Thanks, es 73- Bill

W4BSG is "vanity" this time, but was 
earned by exam in 1954, the first time.
