Disk: Elektronica BK
|
|
====================
|
|
|
|
The BK (an abbreviation for бытовой компьютер --- 'home computer' in Russian)
|
|
is a Soviet era personal computer from Elektronika based on a PDP-11
|
|
single-chip processor. It was the _only_ official, government approved home
|
|
computer in mass production at the time.
|
|
|
|
It got a floppy interface in 1989 when the 128kB BK-0011 was released. This
|
|
used a relatively normal double-sided IBM scheme format with 80 sectors and ten
|
|
sectors per track, resulting in 800kB disks. The format is, in fact, identical
|
|
to the Atari ST 800kB format. Either 5.25" or 3.5" drives were used depending
|
|
on what was available at the time, with the same format on both.
|
|
|
|
Reading disks
|
|
-------------
|
|
|
|
Just do:
|
|
|
|
```
|
|
fluxengine read bk800 -o bk800.img
|
|
```
|
|
|
|
You should end up with an `bk800.img` containing all the sectors concatenated
|
|
one after the other in CHS order. This will work on both 5.25" and 3.5" drives.
|
|
|
|
Writing disks
|
|
-------------
|
|
|
|
Just do:
|
|
|
|
```
|
|
fluxengine write bk800 -i bk800.img
|
|
```
|
|
|
|
This will write the disk image to either a 5.25" or 3.5" drive.
