More Version E Replacement mysteries. When I got my replacement Version E they of course included new batteries. They would seem to be new and the calclator works fine.. BUT, when I run the diagnostic test, ON-D MTH it says ESD 210V 210V And NOTHING else.. There are no bars at all.. Now I distinctly remember doing this same test on other 48s including my old version C and they always gave me the 4 bars in a pattern like. ESD 210V 210V | | | | | | | | Same as before, anyone else? I don't think I have ever actually heard anyone say how to read the status of the batteries from the information given by this test. The manuals just say, "The bars indicate battery status". Yeah right. ian -- -=Runaway Daemon=-

Ian,
When ever I ran the ESD (electrostatic discharge?) test, my rev B would
just start beeping (forever), but know bars.

Nickel The thing is that I am 100% positive that my version C displayed little bars, along with the 210V stuff and the contunual beeping. IF you look in Jim Donnelley's handbook it says when in the diagnostic mode that "[G] ESD test monitor. Bars indicate battery status." The regular manuals say nothing at all about this. I suppose I will have to wait until the batteries get low. I would like to know if the pressence of the bars indicates that the batteries are getting low. ian -=Runaway Daemon=-

Ian,
I think Jim Donnelley might be wrong. I am pretty sure (but I woudn't
put money on it) that ESD mean electrostatic discharge. I mean, come on,
210 V batteries? Yikes! I think its some indication of how much ESD
that squeeks through on there electro-shock therapy tests.
Derek S. NickelTNAN0@CCVAX.IASTATE.EDU (02/21/91)
When my calculator (ver. D) was new, I had two bars (one under each 210V).
When my calculator's batteries got low, I had the following:
ESD 210V 210V
| | | |
~~~ This bar flashed sporadically, then stayed on...
With new batteries, I get NO bars... I can only assume this means that the
bars indicate varying levels of... Hold on, I just figured it out!
Ok, the:
210 represents ports 2, 1, and 0 (system). If NO cards are present, port 2
always gets bars under it (under both 2's) -- Why? I dunno... See if this
happens on yours... (If not, perhaps there is something wrong with my port 2).
Rom cards always return good voltage (or so it seems). RAM cards will show
bars if their batteries are low and port 0 will show bars if the AAA
batteries are low. Apparently, the bar on the left is a real-time display
of the test (for example, if the batteries are semi-low, these bars may
flash as the test passes and fails). The bars on the right latch a failed
test on the left. In other words, if at any time during the test, a port
fails, the bar on the left will flash and the bar on the right will stay on.
Can someone confirm these results? (Whether or not bars ever appear under
the ESD or Vs I cannot tell... Does Jim's book mention what these represent?)
So, basically, the 2 is P2, the 1 is P1, and the 0 is S in the LowBat(S,P1,P2)
message...
Apparently, the readings you get without cards in the ports are not reliable.
They change from "bar" to "nobar" to "flashing bar" depending on the level of
the batteries in the 48sx and some function of cosmic ray intensity...

P.S. My Smith-Corona 32K card is still running GREAT, with no errors of any
type. I've tried it with weak and strong batteries (and with no backup battery
in the card) and it still has its memory intact... However, I have NOT
performed a great number of WRITE operations to it... I think I'm going to
create a program to hit it with thousands of write/reads and see if the data
stays intact... I'll report my results as soon as I can... Oh yeah, and mine
has the sticker with the instructions on the back.akcs.falco@hpcvbbs.UUCP (Andrey Dolgachev) (03/02/91)
This is very strange. I tried ON-D and then G on my Ver D HP48sx with
week-old batteries and I got the diagnostic with no bars. I then put in
my previous set of batteries (the caluclator lights up with a lowbat(s)
indicator) and then tried the diagnostic. I got two lines in the
diagnostic, onw underneat each 210v.
Now, Ken Rawlings said that he tried his ver E with fresh batteries and
he got bars. My question to him is how many bars he had?
And, ian got no bars with fresh batteries.
According to me and ian, the bars seem to indicate a low battery status,
no bars means fresh, bars means low. But Ken's is different. What is
up? Anyone else want to experiment with this?

Four bars total, one under each 0 and 2. BTW, I have the equation card installed if that makes any difference.

You have at least one card in the calc and if you had looked closer the line would have been under the 0 in 210V. IF indeed that was the case, then it says that port 0 (The calc) batteries were low. If it had been under the 2 or 1 it would have been ports 2 or 1 with low card batteries, and apparently, that isn't always reliable if the card is not actually in the port. In other words, you might not see a bar under the 2 if port two was empty. I have also played with this bye taking the batteries out of my RAM cards while running the test, and found that if I took the battery out of the SC 32K RAM card in port two I got the bar under 2 and if I took the battery out of the CMT 128K RAM card in port 1 it wouldn't put the bar there. My theory is that the CMT card is drawing so little (see previously posted stats) that it doesn't even know that its battery is missing for a while. Interesting feature though. ian -=Runaway Daemon=-
akcs.falco@hpcvbbs.UUCP (Andrey Dolgachev) (03/04/91)
Yup, it's been solved. The 0, 1, 2 indicate the main calc, port 1 and port 2. A line underneath the number indicates that the batteries are low in that area. --Falco

The way I have found this battery test to be, ON-D g(mth) it shows 210, but actually they represent the ports. ports 2 1 and 0 0 which is the internal port. A bar under the corresponding port number means that their is a weak or no batt in that slot, hence if you have no cards and good hp batteries you should see bars under 1 and 2, but not 0 I have just one card, a smith corona 32k ram, and I see only one bar under the 2 slot. ( the sc card is in port 1). btw, is anyone getting my posts? would someone kindly rply to me via mail..?? I would appreciate it.. thanks jcohen@scarecrow.csee.lehigh.edu or: jcohen@lehi3b15.csee.lehigh.edu

Pardon me, but do I understand you correctly when you say that you have a smith corona 32k ram card for the 48sx ?????? If this is true, does it work?? and is it cheaper that the 32k card from hp?(arount 160$ I believe). Please respond. Kelvin.

I have been using 2 Smith-Corona cards since January and have had no trouble with these particular cards, although I did have to try several out before I found two that would work. Apparently, the calculator is somewhat picky . As I understand it, the HP cards are spec'ed to operate at a slightly lower voltage than the S-C cards. It's purely a matter of luck to find a card that works. Fortunately, the people at Wal-Mart were willing to let me try out each card until I found one that worked. The most common indicator that a given card would not be compatible is an "INVALID CARD DATA" error. Just head to your local Wal-Mart, calculator in hand, and surprise the clerks in the electronics department. $23.84 for 32K ain't bad!!! Just be patient, though - I had to try 10 cards before I found a couple of "good" cards. Of course, this is only my limited experience, and you take the life of your calculator into your own hands...... tom baca

Well, I'm heading over to the local Montgomery Wards right now!

Just head to your local Wal-Mart, calculator in hand, and I am sorry that you went through so much trouble, but this isn't true. If it were then I would have had to send back my CMT 128K card and HP 128K card. They both gave me the INVALID CARD DATA when I put them in the first time. Actually, I have had the battery out of the HP card long enough to let it fade away, and it gave me that error again when I put it in. The SC card I have also told me this. IT is just because the card is pretty much scrambled when you put it in the calc. As soon as you merge it, it formats it to something that it likes.. As for finding BAD cards... If you put the card in the calc, turn it on and the screen goes black and then does the fun fading effect, then you know that it is bad. Pull the card emediately. Don't worry about whether the calc is on, just get the card out. Use the reset button to restore it. I had this happen once when I put the card in another person's calc who had a VERY VERY low battery. ian -=Runaway Daemon=-

Hi Kelvin,
If you want to find the SC ram cards cheap, try Bizmart up on
Oracle. I picked up a pair there a month ago for $19.93 each! So far I've
experienced no problems at all with them and my batteries are over 4
months old with relatively heavy IO usage...transferring matrices to/from
spreadsheet, backups, etc..

If you plug in and pull out enough of them, you will *DAMAGE* the calculator. Note that non-HP-48SX cards that seem to be "good" can still damage your calculator, if the batteries get low, or if the calculator gets warm/hot (or it is cold?).

a card that says invalid card data is not a bad card. All cards that are new and never been touched can say that.. a bad card either will give an error when you merge it or it will melt your screen when u put it in... jcohen@scarecrow.csee.lehigh.edu

My one and only real complaint against HP products is that they are largely overpriced. I realize a lot of r&d goes into their products and they really make the best stuff around (as far as calculators go), but I can't believe HP needs to charge 25 bucks for a crappy plastic cover or 35 bucks for a silly rs-232 cable to cover development cost. They certainly don't put much development effort into their memory product; at least not more than the guys who are charging $20 for 32K instead of $100,000 or whatever HP charges. If they had reasonable prices I would probably buy tons of merchandise. I spend much less now on HP products than I would if they charged less. I guess they just don't want to go the low-margin/high-volume route. -- Steve Scherf steve@Altos.COM ...!{sun|sco|pyramid|amdahl|uunet}!altos!steve These opinions are solely mine, but others may share them if they like.

It is apparent that the vertical lines represent battery status for the various ports/system. However, like Derek, whenever I do the ESD test, I get continuous beepings from my HP. I'd like to think it was just saying "Hi, all's fine. Happy programming," but (call me crazy), short high-pitched beeps in a hurried frenzy tends to make me question the friendliness of the message... Scott.

My roommate and I just replaced the batteries in our two HP's at the same time. I did the ESD test and I got about 8 pixels on the vertical lines, while he had no lines at all. Could someone tell me exactly what the ESD actually does and why there is this difference between our ESD tests? (I have a rev E and he has a rev C if that makes any difference. We both have a 128K ram card.) Thanks for the help!
