I had difficulty reading a damaged 360 KB floppy a while ago. I finally got an image of it using RESQFLPY, however certain files were still corrupt. Others were OK though.

That is essentially the same I did.
Made a copy of the disk and then ran Norton Utilities on it (since the original was unreadable under DOS and I didn't want to cause further problems).
I think some of the files were corrupted, but it's fortunately not a crisis.

But, as you've stated, once a disk goes bad, then you can end up with some files being corrupted.

Hi

Iam now being busy trying to make an image of the disk..

There are a few bad sectors on the disk, but it seems to be readable fine on my NEC V20 XT clone.. I can tell these files are on the disk:

Command.com
Cdisk.sys
Config.sys
Turbo.com
Turbo.doc
Cdisk.doc
Tu.com

7 files 30,203 bytes used and 274,432 bytes free.. Iam trying to upload the copy i made, but can tell if it would work for you.

Device line in config.sys is

device=cdisk.sys

Has someone the diskcopy.com file from Dos 6.22 for me?

Thank you for the files.
Sent you a PM.

I think iam going trying to use diskcopy to clone that protek disk.. First cloning it, then trying to image the good copied disk in my Pentium III 550Mhz setup with 360KB disk drive installed..

I use a USB transfer cable to transfer the files from internet from the Intel core i7 2600K to my pentium III machine.

Hi
Can you scan this motherboard's manual ?
It apperars to be the same of mine.
Thank you,

Hi,
Im looking for help, my JUKO ST (green board) find some damages
Can someone help me, what is the resistance on the board:
R1=
R2=
R3=
R4=
R5=

Thanks

All 5% tolerance.

Miphee thanks a lot

HI everybody!
I own the same motherboard and have a big question.
There is no batter in this board.

I cant put to run, I'm in the process of clean, and waiting for an XT keyboard.
But I inspect in the clean process and won't see any battery.......

Some info about this please?

No battery here (thank goodness). The IO card you use for it might have a battery for time (mine does). And then you have to use TIMER.COM to program the time or propagate it to DOS during boot... or just enter date/time on every boot (vanilla DOS boot without Autoexec/Config).

Fantastic board if you ask me... and the turbo button makes all the difference for XT-class software.

Thanks for the info wbahnassi
And yes no battery here.

One more question.
This board only work with 5 1/4 floppy 360kb?
NO way to make this work with 1.2mb floppy?

I think XT cannot recognize 1.2MB, but I remember I read there were ways around that. My Juko machine came with a 360K 5.25", a 720K 3.5", and a 10MB MFM HDD. The floppy drives connected to a controller card that has a battery on it too, and the HDD connected to an MFM controller card.
So yeah, the design allows for 720K floppy drives at most. I haven't tried connecting a 1.2MB to it, but the mobo's dip switches can only specify how many drives you have connected.. not their type.

Does allways c14 getting so hot? 62 C
RAM and chipset cold...
POSTcard little use...
Won't boot, tried 4 bioses
https://theretroweb.com/motherboards/s/auva-c … -baby-xt-bxm-12
must be something like this...
Open to suggestions!

Hi, @Robin4,
And thanks for the shared utilities diskette image.

TU.COM utility is pretty useless in this state - it only resets wait states to their default values.

There is something wrong with the TU.COM disassembled code shown here, since it generates 5 bytes of redundant data code (DB) at the end of the com-executable. Probably this is also a result of improper floppy bad sector recovery.

The TU.ASM code should look like this (without the useless DB data at the end):

1    org 100h 
2
3    cli
4    in      al, 70h 
5    mov     al, 95h ; 1001`0101b 
6    out     70h, al 
7    sti
8    sti
9    int     20h 

TU.COM should be 11 bytes in size, not 16.

I have some newer tools and utilities for Juko Super Turbo motherboard, that come from another setup diskette. I can't recall from where I got them.

STURBO.COM - a newer version 3.00 of TURBO.COM
CDISK.SYS - a newer version 3.00 of RAM disk driver
CCACHE.SYS - HDD caching driver ver. 2.00
RATE.COM - HDD cache hit rate checker ver. 1.00
CPRINTER.SYS - printer buffer driver ver. 2.00
CP.COM - clears printer buffer ver. 1.00
READ.ME - some brief text documentation
README.COM - shows READ.ME
INSTALL.EXE - installer

P.S. Ans here is the correct TU.COM utility - 11 bytes in size:

It is still almost useless like the damaged version from the recovered diskette image. Who will gonna change wait states set by jumpers to their defaults from DOS, and why? I have some better idea for this piece of code.
