Hi,  

It would be great to see examples of loading .TAP and other file formats using the "TP" command in AMON.

AD <A> <C> [<G>]     Absolute binary dump, optional GO address
AL [<0/1>]           Absolute binary load, 0 prevents execution

The AMON “TP” command isn’t for loading .TAP files. It sets the serial port user for transferring HEX files:

TP [<0-7>] (SET TRANSFER PORT) The Transfer Port is the port used for transferring Intel hex files with the AD, AL, HD, HL, and TE commands.

Hi,

To me it looks like I could choose “3”, then the computer would allow the MITS compatible ACR interface to receive data (.TAP file) and push that data into RAM.

or … chose “5” and a MITS compatible parallel port would accept data from a parallel paper tape reader and push the data into RAM.

Yah, it looks like that could be case, but the documentation says it is only used to set the serial port used to transfer Intel .HEX files.

Hi, 

Either way, IF somebody ... even multiple people with different setups could demonstrate from Power ON to AMON selection to hardware connections, to front panel toggles with posted code in the chat to show the whole process for those various choices, it would be helpful for anybody using the AMON monitor ... especially with the 88-2SIOJP boards.
