FP-301D ID PROM

 

Hello,

The FP301D power supply had speaker, clock and CW Morse ID system
The dealer would program an olde school PROM for your call.
Does anyone have any info on the PROM programming format?

Thanks in advance,

Randy
 
Edited

A wonderful FoxTango member just sent me the FP-301D manual in Japanese.
It has the ID PROM programing data in ENGLISH.
Eureka.

I am uploading to Files.
 

My PROMS from Bulgaria and Jameco arrived. Need to buil;d package to sedn to Canada to get programmed with "de W7CPA ar".
TELSA and National proms same as TI allegedly, we'll see.
 

Are you having someone burn your PROMs or are you planning on doing it yourself, Randy?

I looked at the ARLabs programmer and adapter and may spring for the combo if I can't find someone to burn an image. Would come in handy for an FT-980 project I have in mind too,

This guy claims he can do it. I am sending him 2 PROMS, one alleged Telsa clone and one National that has a data sheet the same 8x32design and pin out.
 

JAMECO has these perfect matches.
I will report programming progress.
The 288s are just more robust for MIL applications.
The CW ID should be a no brainier.

First test almost perfect.
Telsa 188 clone and TI 288 work fine.
I screwed up the programming so one more time.
is going to program one more time with my correction.
I didn't transpose the manual work sheet to the ordered 2 byte programming sequence correctly, hosed? one byte up.

The result was DE W7CP <bluh snuf, mumble> AR

Finally 100% it's alive.

The Japanese FP-301D manual is correct.
It's just a bear to markup the sheet with a pencil and then create the ordered 2 byte list for a PROM Programmer.
I did this for grins and probably will never use it.
The 10 minute timer only works if PTT is enabled for 10 minutes straight with no interruptions.
Interesting olde 1970s digital design.

Cheers all,
 

Wanted to chime in with thanks. I intend to do the same for my FP-301D, perhaps with a mod to actuate ID on demand. I am not long winded enough for a ten minute timer!

There's a sw on the front already for ad hoc IDs.
I'm on 3853 LSB it you's like to hear it.

I have no clue how I missed this group/thread other than I may have been too excited to do a thing before needed to know if I had to do a thing.

I got one of these with a FT-301D and FV-301D and since I do a lot of work on old embedded/arcade stuff...I work with parallel EPROMS all the time. So I sat down a few hours ago with the schematic and basically reverse engineered that the data was timecode with sequential addressing. Actually...the minute I saw the 74151 and 7493s I started guessing when they said "time-code" in the US manual they literally meant time-code.

Anyway...the only thing I hadn't worked out was the bit length of various things, which now that I've got? the Japanese manual with that information I'll have zero guesswork when doing a mockup. I might try to write a python application that will generate an image file that'll work with image burners. I'm also considering if my clock chip doesn't work just replacing everything with an Arduino and RTC module.

Good stuff, keep those geezers running.
I am off on other projects for a while now.
