Re: ADT with a Laser 128



It seems you have done some homework. Personally I never had any compatability issues with the laser128 I had. I'll have to try the memory address continuation thing in the monitor program. Currently I have a version 4.2 (Thankx Roy) and (gasp) it too fails the continue entering numbers test. You are not alone.

Thankfully you have the answer to the initial problem, include the memory addresses in each line of ADT.DMP. (Catch that Jeff?)

I will simply have to try the Laser128 and see for myself about transferring disk images via ADT. It should be compatible... Of course I don't use any term software for the initial transfer, I just null-modem connect and have the TP Type the file to the port. (Type adt.txt >com1)

I'll have to see about using a serial card in the expansion slot too. This really bugs me that it failed. (I use a SSC in my IIgs for transferrign becasue the 'modem port' is not compatible on it. (I of course had complete success using the IIc.)

And the whopper:

- For some reason, the monitor (CALL-151 to * prompt, not video monitor) on
my Laser handles the following sequences differently than other Apples:

CALL -151
800: 1 2 3 4
: 5 6 7 8

This SHOULD put "01 02 03 04 05 06 07 08" into 0800 through 0807 - but it
doesn't. The second line vanishes into never-never land, so you end up with
"01 02 03 04 00 4C 00 5F" or other such garbage. This makes the ADT.DMP fail
even if you get it to transfer. It took a while to notice. I suspect this is
what caused an issue reported in 1997 in this posting:
http://groups.google.com/groups?selm=65ao1d%24iob%241%40hyperion.nitco.com&oe=UTF-8&output=gplain

The fix is to include the memory addresses for each line in ADT.DMP; I
whipped up a quick Perl script to add them and everything is happy.
Strangely, I can only find that one other report of such an issue. Is it a
known problem with the Laser's monitor routines?

Anyway, as Calthaer reports, the Laser 128's serial port is not compatible
enough with a SSC for ADT to do its trick. Damnit!

Okay - now that all of the above is reported to the newgroup for future
generations to Google on, and now that I've proved I'm actually trying
things out, here's my actual question:

===================

Assuming the above setup - a terminal program on the PC and Apple2 capable
of basic file transfers (e.g. Kermit, XModem, etc) - what is the most
efficient way to transfer disk images to the PC for use in an emulator?
...
are there other routes?
