[comp.sys.handhelds] Elek-Tek, flicker, Amiga owners, free memory

ram@tellabs.com (Bob Martin) (10/02/90)

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.

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)

The MEM command performs garbage collection.  You are getting smaller results
because some memory is in use.  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.
