Subject: Legal Source of ROMs

I was going to remind everyone that the ROMs in an Apple computer are
accessible, demonstrating the idea with my clone, but it hasn't worked.
That's because I have a Laser, not a real Apple.

I TRIED to port over the ROMS from my Laser EX/2, starting with the
following commands:

BSAVE SERIAL.BIN, A$C200, L256
BSAVE FLOPPY.BIN, A$C600, L256
BSAVE  APPLE.BIN, A$D000, L$3000

The resulting files are the memory dumps of the ROMs.  When I ported them
over to the IBM, I had to strip off the leading four bytes and trailing
bytes ... that isn't too hard.

Alas, the Laser ROMs are still too different, and Apl2em choked out
something like "Badly formatted Serial ROMs".

I would be very interested if someone has been able to do this with a real
Apple-Computer-Inc. Apple.  Or if someone knows that SERIAL.ROM is not a
real dump of a Super Serial Card rom.

Would someone like to forward me a working SERIAL.ROM?  I have a good
APPLE.ROM and DISK.ROM, it turns out.

apl2em is configurable, can run without serial roms

REMINDER:  To Run Without SERIAL.ROM

I'm running Apl2Em version 2.

1) It is configurable.  The file APPLE.INI is very easy to figure out.
   So I took out the serial card, since I'm not going to use it.  And
   I added a few more disk controllers, since I certainly can use more
   online volumes.

2) If you have a disk controller in Slot 7, it will boot off that.

Subject: applemu

The "other emulator" that someone mentioned, "APPLEMU", is available at
wilbur.stanford.edu .  I've gotten it and tried it, and I think it really
deserves at least a look by everyone.

1) It handles disk swapping.  One function key (F5?) prompts for the new
disk in Drive 1 (you type in a file name); the next key (F6?) prompts for
Drive 2's.

2) It asks if the disk is to be write protected.

3) It runs on 8088s on up.  You need a CGA or better.  I can run it on a
Hercules card with a CGA simulator.

4) Other function keys:
      F1 - RESET (resets the apple)
      F2 - Quit emulator
      F3 - Left arrow
      F4 - Right arrow
      F7 - Set up the com port
      F8 - (nothing, but I see a stub in the code where F8 was "Debug")

  Notice!  "PrintScreen" worked on my set up.

A very solid emulator, including COM port support.

(A few not-so-greats: It's a 48K Apple ][+, and uses a 243K .DSK file that
is on the nybble level.)

It may not be your emulator of choice, but it served to remind me that
features like disk swapping can be had with a little programming effort.

MASM question - Apl2Em

#133

What I'm really looking for is someone who has assembled apl2em
or apl2em-2 ...  Read on ...

I downloaded it all and unzipped it.  One of the first things I wanted
to do was MASM it and LINK it.

No go.  I have access to an 80286 with a megabyte (that is, the usual
640K and another 384K of extended memory).  But it reliably yells:

     * Out of memory *

... on each assembly, then goes on to fail on the next module.


My problem is that I don't know if I'm REALLY out of memory, or if
the code, which is heavily macroed, is in an infinite macro.

Can anyone with the experience shed some light here?

Thanks.
