It seems to be "save link as" in Firefox, but it does the same thing.
The other choice, "copy link location," copies the link to the
clipboard, such that you can paste it somewhere.
One place is to a command window with a wget command.

I got the Mon.Asm Assembled using the ASM.Com and ran Hex2Bin; but how
do I get it to run
On what Machine will it run
Also can that code be put on an EPROM.
I might be able to get it over to my NEC APC and try MS-DOS 2.0
I can put it on a 5.25 then copy to a 8" SSSD CP/M format floppy then
MS-DOS 2.0 on the NEC will copy from the CP/M floppy to the Dos Floppy
using RDCPM.
Too Bad there isn't a reverse program that will copy a File from the NEC
DOS back to a SSSD CP/M 8" floppy.
Is there anyone who might be able to reverse engineer RDCPM if I can get
it back to CP/M
I should be able to de-assemble using DEBUG. I'm a Newbie there put
Practice makes Perfect.
I have an image copy on the NEC of the 8" SSSD SCP 86-DOS V1.0
I used DEBUG to read in the 8" and saved to a file. its about 132000 bytes..
I put it on a DOS formatted SSSD 8" but at this point can't read it
anywhere else except on the NEC.
If I get my COMPATICARD PC Running then I should be able to read 8" SSSD
Floppies

Hello Bob,

The monitor is 2k, so you can burn it into a 2716 or larger EPROM. The
reset vector for the 8086 is at FFFF0h, and that is the entry point
into the monitor, so if you are using a 2716, you would set the ROM
base address to FF800h.

It should work with any 8086 CPU board provided that the board, but if
it's a dual CPU board like the CompuPro, then it would have to be
configured to start with the 8086 active.

The monitor expects a SCP300E support board for the I/O, but it really
only uses the UART at F6-F7h, and it checks a "sense switch" at FFh to
determine whether to enter the monitor or jump directly to the disk
bootstrap.

If there is no I/O port at FFh, then the CPU will most likely read FFh
from the floating data bus and jump to the disk bootstrap.

Probably the easiest thing to do is modify the monitor for your own
UART, and skip the sense switch check.
