Determining HP 48sx ROM version by SN? - megarat - 04-12-2010

Hey all,

I've decided to get back into the RPL game by hunting down a 48sx. Ideally I would get one with firmware/ROM version J. (Unless you can recommend an earlier version instead, for a reason that isn't obvious to me.)

So: is there a way to determine the ROM version by the serial number? Most eBay sellers seem to balk at going through the steps of determining their ROM version, but don't have much issue with providing an SN.

(I suspect there is probably a very clear relationship between SN and ROM version, so I guess the second-order question is: has this relationship been properly mapped out? A survey of HP48 owners would be the obvious way to do this. (Although such a mapping would exclude units that have been factory-upgraded by HP, of course.))

I can't say how strong the correlation is, but here's my J ROM unit as a data point:

3310S04480

I've got another SX at home that's not rev. J that I can check later this evening.

The steps for checking the ROM revision in an SX are so simple that I'd be surprised if any decent seller wouldn't take the necessary 30 seconds for a potential buyer. All you do is press On+D, Backspace, Eval, which prints the ROM details plain as day. Then press ON+C to resume normal operation.

I have a 48s ROM Version J (not SX) SN 3311S00452, If you're interested, send me your address.

I'm with you on that ... I ask politely, ask early in the auction cycle, and even include the instructions, but so far, every single time I've asked, I've either received (a) no response (four out of six times), or (b) an unhelpful waffling akin to "all I can say is that it's made in [country] and passes the self-tests" (twice).

I generally take this as an indicator of someone I wouldn't want to do business with and keep looking.


Re: Determining HP 48sx ROM version by SN? - megarat - 04-12-2010

Very cool, thanks.

There seems to be a clear relationship between SN and ROM version. It would be terrific to nail them down a bit more (e.g., are the version boundaries between US and Singapore models the same?).

I'll maintain a list of all responses here. If you (generically addressing the reader) can provide your SN, specific model, and ROM version, I'll keep adding to the list, at least for the near future.

I also have one with serial number 3006A00426 (48SX) but its screen is broken. I'll add its ROM version once I get a screen for it.

I suggest to create an article. As soon as this thread is archived you won't be able to modify it.

Best regards

Re: Survey: what is the serial number and ROM version of your HP 48? - megarat - 04-13-2010

Thanks for the suggestion, I didn't know the difference. I'll do that.

EDIT: I've done so, the article is here: http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/articles.cgi?read=991.

According to the MoHPC's table of "Earliest Serial Numbers (so far)", this takes the prime spot.

Is that page/table updated frequently?

I told the mr. Hicks about that but no answer received.

I think it's just curious.

Sorry, I didn't think to state since the OP was about SX. They are both SX.

Re: Survey: what is the serial number and ROM version of your HP 48? - megarat - 04-15-2010

Thanks everyone for your posts thus far. I've been updating the article here.

I'm not trying to be exclusive of the 48s series ... if you want to submit your G/GX/G+ information as well, feel free.

Regardless, I'm particularly interested in cases that help define the boundary conditions (e.g., where the versions change).

Happy to oblige. HP-48G, version M, 3344S06734

Re: Determining HP 48sx ROM version by SN? - Mike Morrow - 04-16-2010

My units:

HP48SX ROM Version E 1989 3117A00013

HP48GX ROM Version R 1993 3629S01544

HP48GX ROM Version R 1993 SG72400781



It's interesting that there are 3116S and 3117S listings here, even though my SX is definitely a 3117A. I guess there was some overlap of the American and the Singapore manufacturing process for the SX.

Re: Determining HP 48sx ROM version by SN? - megarat - 04-19-2010

I agree, that's an interesting overlap.
