Hi all........

Good to see the list back again......

Recently I picked up a Sony SMC-70 with CP/M for Sony on floppy disks. I
have recreated what the original owner had by purchasing the same model
monitor and using his cable to connect the computer to the monitor. This
is not the OEM monitor (anybody know what was?) but this setup worked
for him.

When I turn on the computer it scans for the floppy in a:, b: and then
pauses and comes back to a: and reads the disk for about 12 seconds.
Nothing more happens. There is no display on the screen.

If I leave the a: drive empty and have *any* floppy in b: the computer
scans a:, then b: goes back to b: for a couple of seconds then begins to
beep until I put a floppy in a:. Still nothing on the screen.

There is a switch on the side that has 3 options: OFF DISK ROM I have
tried all three with no output to screen.

Things I have done.

1) Double checked the pinouts against the drawing I was given.
2) I have tried the cable that connects to a B/W port on the box. I
connect this to video on the monitor.
3) I have tested the monitor. I know it works in TV and video mode, but
have no way to test for RGB. Which is how I am connecting.

I am wondering if the floppies may have gone bad. (There are 4 disks
labeled CP/M 2.2 and one also says Sony CP/M 2.2) They have been laying
around for several years I think. If this is a possibility does anyone
have known good floppies?

thanks for any info
