Just to let everyone know, I got my 48SX yesterday at Elek-Tek, and it had the version E ROMs. Quick side note: I'm surpised I haven't seen anybody in this group mention them in the month I've been following it. Their price is 249.00 which is 30.00 cheaper than EDU-Calc, and they have pretty good support. Of course it helps that I live in the Chicago area. Their number is 800-395-1000. Since I'm a new owner, I have a few questions: 1) Flicker: When the display is on there is a noticable flicker to it. The darker the display, the more noticable the flicker. It's like watching a TV with a slow scan rate. Are they all like this, or is mine not up to snuff? 2) Free Memory: When I do an ON-C, and then an immediate MEM command, I get 30213.5 in 1:. If I do a drop to clear 1:, and then immediately do another MEM, I get 30200. After a few minutes of calculations, followed by a CLEAR and PURGE of all variables, I'll get a number somewhere in the 29K range. Is there some way of doing garbage collection without doing an ON-C? 3) Amiga owners: I have seen a few people in this group mention they are Amiga owners, and so am I. I would be interested to know if you have found out how to get the HP programs that come with the serial cable, but work with the PC or Mac. Have these been converted to Amiga? Also, did you buy the serial cable (sans software) from HP or make your own? Finally, even if you own a 48SX and an Amiga and don't have any info for my questions, please send me a EMAIL message with your return address. I will compile this list and EMAIL everyone back with a list of all the 48/Amiga owners. In regards to my cross-posting to tellabs.general, if anyone here at Tellabs (or anywhere in the western suburbs of Chicago for that matter) owns 48, give me a call at 512-7853 if you're interested in exchanging software or forming a users group. Thanks for any help, and sorry to take up so much bandwidth. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bob Martin | ram@tellabs.com ...!uunet!tellab5!ram Tellabs, Inc. | "Listen to me now, and believe me later" Lisle, IL. 60532 | - Hans und Franz

1: HP48 flicker: caused by flicker in flourescent lights. . 2: HP48 garbage collection can be forced by the MEM command. . 3: Add me to your list of Amiga owners (haven't turned it on for 2 years because of *its* flicker. . (1 & 2 are are prime candidates for the FAQ list) John Serafin jpser@cup.port{al.com

The calculator remembers certain things: The stack as it was before the last command, the arguments of the last command, the last four command lines entered, and the last program in which DOERR was issued, if the argument was a string. If you've entered large command lines recently, they are still around, taking up more memory than if only small lines had been entered recently. You can clear the last stack, arguments, and command lines by going into the mode menu and turning off and on each of those options. You can clear the retention of the last program that issued DOERR with a string by executing 0 DOERR. -- edp
