This is Pravetz 8D. The computer is small and has useful
keyboard - something that have not at many of other home computers at
this time. |
 |
This is empty board of Cumana floppy drive controller |
 |
This is bottom page of the computer. The most important is
Reset-switch, which connects low level to NMI pin at CPU. This is not
usable every time computer freeze. Sometimes you must use power switch.
You can modify your Pravetz 8D to have real Rest switch. You must go to
HARDWARE page to do it. |
 |
This is populated board of Cumana floppy drive controller |
 |
This is back side of Pravetz 8D. There's some economies at
last models - if you look carefully you can see that there's no UHV at
right. |
 |
My new Cumana floppy drive. It's Sedoric compatible and work
perfect
with Pravetz 8D and Oric too. There's PSU, Cumana controller and two
3.5" drives at the box. I hope you enjoy the vision. |
 |
Inside of Pravetz 8D. You can see the integrated PSU. Every
Oric fan respect it. |
 |
Another view of my new drive. |
 |
My first floppy disk controller. It's Pravetz 8D and Pravetz
82 (Apple ][) controller at one board. It supports overlay RAM too, so
you can use not only Dos 8D v.1.x, but Dos 8D v.2x too. |
 |
When working my Cumana light beautisul. |
 |
Pravetz 8D desktop. I use box from the first Bulgarian
PC-clone - Pravetz 16 S. There's motherboard, floppy drive controller,
floppy drive and PSU from Pravetz 8M too. |
 |
My dream come true - original Oric Atmos. The computer is
smaller than Pravetz 8D, because of the external PSU |
 |
This is something almost impossible to find even in Bulgaria
- original
Pravetz 8D floppy drive. It was born 4 years after Pravetz 8D's birth.
The controller has built to work with PC floppy drive, but uses Apple
][ disc format. The drive don't work with Dos 8D v 2.x, so you can not
load long games without modification and cutting the programs. There's
integrated PSU under the cover. |
 |
Something difficult to find - original 3" microdisc. There's
a controller board under the cover too. |
 |
This is Pravetz 8D, floppy drive and Pravetz printer - M88. |
 |
There's something missing you can see. There'll be an oric
printer too soon I hope. For now - Oric + streamlined floppy
drive. |
