Hi all, As I stated in another thread; I am also a curious soul who wanted to get an FP-301D CW IDer working; although I took the different route of reverse engineering the basic format. Then I found that Randy/W7CPA got the Japanese manual with the programming table. It verified what I'd figured out with the exception of giving me bit lengths to work with.?I am planning on writing a small simple utility in Python (or some other language possibly) that will generate the binary data you need to write to an EPROM/EEPROM that should work with some logic level circuitry. There's also no reason this same data wouldn't be useful on the original style PROM. Data is data...you flip addresses on and you get data out. Everything else is just TTL vs CMOS and open collector vs tri-state.? Thus far, I've made a table of letters and numbers that contain the bits needed:? I also...using my own list...worked out "de nq4t" by hand:
75 10 1D D7 15 1C 70 00
Yes, that's all in hex. This the first thing I have to figure out the best way to handle. All the numbers and letters are varying bit-lengths and due to being time-code, you can't really just pad things between letters. You could, sure. The only real limitation you have is 8 bits of "0" triggers it to reset the ID circuit. Even the sheets say you can use fewer or more blanks between letters/words as long as you remember that rule. I think there might be a better way of doing it...because at this point I haven't even written any software...all the binary and hex I'm producing was figured out in my head.?
011101010001000000011101000111011101011100010101010111000111
This is the binary string I came up with originally. So I just broke that down in to 1-byte (8-bit) chunks:
01110101
00010000
00011101
00011101
11010111
00010101
01011100
0111
As you can see we actually came up with 7 bytes and a nibble. So what I'll need to do is have my software do is just pad everything out to fit evenly in bytes. With a pre-defined table it's mostly just a case of text processing. That's not easy to do in Python so it'll take me some free time to figure it out. I have also considered modding things to replace the 74188 and 74151 with just something like a 28256 EPROM. This would be rather easy to do by tying the address lines for the 74151 to the lower address bits and use the 74188's as the higher address bits. There's more than enough space to waste in a 256kbit EPROM; it would just make programming a LOT more difficult since rather than storing time code as bytes...you'd have to store them as specific addressing. It might be easier to just outright replace all the logic (keyer and clock) with a microcontroller too. But I'll still get some imaging creating software done since I'll need it for my development/hacks. 73, Jay/NQ4T

Hi,
I just came accross this thread.
I purchased the complete Ft301 line back in 1979 still have it brand new and in boxes. In the early 90’s I purchased a bunch of the IC that get programmed for the FP301D.
I looked into this as well and have schematics to make the programmer for the 74188.
Feel free to contact me I would love to get this going again.
There are other FT-301 groups on (groups.io)

Hi James,
Let me know the model number when you get a chance, I still need to program my 74188’s.

Hi James,
It’s not easy to find people that have programmed these, thanks for your help. If you need anything for FT 301s let me know.

Hello Mike,
Just curious, I did a search on yaesu on groups.io and haven't found any other groups specifically for the FT-301. Do you happen to have the names of the other groups? More groups/info can't hurt :)
Thanks,
Jim

I put up the Japanese manual in FILES with English
PROM programmer info a few years ago and found a antique video
game dude to program it. All those old video games people have a
programmer it seems.

Hi James,
My mistake this is the only one. I think that Foxtrot Tango was one some years back.

Hi Randy,
Thanks for getting back to me. Yes these cost a lot but they do the job. I’ll give them a call to see which units are capable of handling the 74188.
Thanks again,

Hi Mike, the info on the programmer was me Jim - KA3EBX. Randy helped me when I was trying to program my prom a couple years ago. I originally used hobbyroms in Canada as Randy recommended to burn my 1st prom then I tried it myself and it worked. I've done a few for myself, my club as well as few other hams. Quoting michael.kohlstadt@...: Hi Randy,

Hi all,
?
I am one of the many FT-301D lovers, the 1979 radio I own was restored and works fine, however I never paid much attention to the FP-301D.
?
Nevertheless, I have programmed the 74188A PROM in the past for other purposes using a? homebrew programmer through a PCs parallel port, something not very ordinary nowadays.
?
After some browsing, I could find many DIY 74188A PROM programmers that can be used by those not wanting to modify their FP-301D.
?
I think the easiest way to do it would be by using an Arduino Pro Mini or Nano, but if one doesn?t mind modifiyng the accessory, the same basic hardware could be used to build a brand new add-on CW ID capable of replacing the entire TTL circuitry of the original ID?er.?
?
Just a thought...

Hi Carlos,
I plan on building the programmer from from a guy online that was designed specifically for the 74188. It’s important to follow the IC manufacturers programming/burning guide lines.
If you come across an FP-301D I’d like to purchase another one.
Regards, Mike
