Default Re: Gemini 80-Bus System

I would
1. Download xbeaver emulator
2. create a local directory ~/beaver/network
3. Run the emulator and execute
copy t-net.com n:
genhex t-net 100

This should ceate a file called ~/beaver/network/t-net.hex

connect the linux box and the gemini with a serial cable.

Using pip on the gemini machine get it ready to accept the file
pip t-net.com=rdr:

Using a terminal emulator send the file t-net.hex to the gemini machine followed by control+z

On the gemini machine convert t-net.hex back into t-net.com with the command
load t-net.com
(If you have a floppy emulator there are other ways to transfer the file, it does not matter
which one you use).

edit the file xbeaver_netserver.cfg to the linux serial port you want to use.

on the linux box run xbeaver xbeaver_netserver.cfg to start the file server which will
serve files from ~/beaver/network

On the gemini box run
t-net n

to start the network redirector.

Now on the gemini n: should contain the file disked.com
type
pip a:=n:disked.com

(This will transfer disked to drive a on the gemini machine).

NB Drive N: on the gemini is the directory in ~/beaver/network on the linux box . This is also drive N: in xbeaver.

To write a disk image to the file use the program called disked on the gemini
A:disked
Disked> (You want the command Fw n:image.dsk xxxx)
where xxxx is the number of CP/M sectors you wish to transfer

At the end type Q to quit disked.

Have fun - I hope that helps.

When I did it I had a real SCSI disk that I pluged into an AHA1542 (I think) Adaptec controller and then did the transfer. Not sure if that technique will work with a xebec controler - might do but you will have to specify the geometry of the disk to linux and hope that the scsi driver sets up the geometry in the xebec controller. Note if you do that you will find that the data is inverted. That is why the xbeaver emulator stores inverted data in the hard disk image files.
