Piccolo RC702 8inch FFD -Boot Problem CP/M

MauriceH · Mar 1, 2021

I have a new problem.
Wanted to start up again my Piccolo RC702 (Z80 cpu) with dual 8" and CP/M v2.2
But no boot.
I had 2 disk that Booted still in 2016 but as to day, sadly not.

Its a Dual side Double Dense 8" that drive could also read single side single dense.
After a search found the site http://www.jbox.dk/rc702/disks.shtm
with lots of RC702 disk images, BUT those are 5,25 FFDs.

after reading the manual and opening up the CPU box, indeed a 5.25 FFD (360k) could be attached.
Also a switch (BIT-7) had to be turned over to go from MAXI to MINI drive.
And YESsss Boot: RC700 56k CP/M V2.2 rel 2.1

BUT there is the problem how to get it on that 8"drive?
Due to the switch setting there is no communication to both the 8"drives.
8" are external drives, and 5.25 are internal.
Also I read about a clock that is changed at the floppy controller 4-8MHz with that BIT-7 switch.

What to do next?
I know about the program 22DSK144 to read CP/M disks on DOS, but I am not found yet a
disk setting that can read the new made CP/M v2.2 or a 8" in the listing.
I Know CP/M is system depending, but not that many I think? Still a Z80A cpu.

I have attached the 8"drive to a DOS machine running IMAGEDISK 118.
Have the Boot image CP/M V2.2 but written from a 5.25 360k FFD.

Question,
Can I somehow change that Boot disk to the 8" FFD?

would be great if there is a way out.

Thanks,
Maurice

After just lot of trying I found out that the mode In 22DSK142 is DEC3- VT-180 SSDD 48TPI 5,25

Can read the directory, so far so good, also could a file translate to a DOS file.

But with ANADISK and a fresh unformatted new 5,25 ffd and made the image again from CPM56k.img
I found out that it shoud be a Double sided disk.

I could not find any other mode in 22DSK that match the criteria.
Some are close like SIE2 Siemens PG-675 DSDD 48tpi ,but it made errors.
Also Same NEC3 DSDD 48tpi and Epson QX-10 DSDD 48TPI.

So seems the basic format of the DEC VT-180 is the right only SSDD, is there a way to
change that to DSDD?

Then With reading the Sector I indeed could read "Copyright Digital Research 1979" So Dec format must be the right one.

I made some progress in Understanding this CP/M reading of disks.
Also I realise this must be in the CP/M Threat of the forum.
I'll ask the Mods. to move the thread.

Reading RC702 5,25 DSDD 48TPI disks in the program 22DSK.
We have to make a new configuration in the CPMDISKS.DEF File
That file is not editable so we have to make a CPMDISKS.NOI file with
c:\22dsk>STRIPIDX CPMDISKS.DEF CPMDISKS.NOI

Now we can edit *.NOI with a new config.
But what are the defenitions off all the paramaters, I could not figure that out by reading the 22DSK DOC.

After editing the *.noi file back to DEF -file
c:\22dsk>GENINDEX CPMDISKS.NOI CPMDISKS.DEF

So I found the Windows RC700 emulator with the Images CPM56k.IMD and MBASIC.IMD
Start Emulator with
c:\RC700emu>RC700 CPM56K.IMD MBASIC.IMD

Emulation started now with a Drive A: and B: , Great!
The 22DSK doc Basic Program typed in, and RUN it.
YES!! All Parameters shown.

With Those I made a new config "RC70" for 22DSK.
And I now could read the Original CPM56k real floppy I made Through Imagedisk.

So I thought great I'll make a New CPM56K disk with Basic and that new typed 22DSK.BAS File.
BUT! I could not make a New Image from that new made CPM56K.imd that was made on the Windows CPU with RC700 Emulation.
Seems it was made at High Dense So had to configure in Imagedisk the TransferRate 500k->250k as I write to a Real 360k Drive
Perfect no problems.

But in 22DSK the Disk could NOT be read still.
After a deep look with again ANADISK I noticed a Change in Sector Numbering. What?
The Original CPM56k.IMD is numbered 1,2,3,4,5,6,7,8,9 sectors of 512k
The new made CPM56kN.IMD is numbered 0,1,2,3,4,5,6,7,8 of 512k
So I made a new Config "RC71" with the new sector nummering, That works also.

So Have 2 new made config files RC70 and RC71 to read Both type of RC702 5,25 Real Disks.

With That The new goal is still to get to read the 8" floppy drive.
For now I still can not figure out the parameters in 22DSK.
At least I think I figured out the sector sequence and makes a steps 4
1,5,9,13,2,6,10,14,3,7,11,15,4,8,12 something like this.

For your two Definitions "RC70" & "RC71" the total number of tracks per side is 35 with the total being 70.

You can verify this with the Imagedisk Utility "IMDA". I use DOSBox on my Linux Laptop to get more information
on the *.IMD files.

Code:

IMDA DOTEST.IMD > DOTEST.TXT
IMDA GAMES.IMD > GAMES.TXT
IMDA MBASIC521.IMD > MBASIC521.TXT
IMDA WORDSTAR.IMD > WORDSTAR.TXT
IMDA RCTEKST.IMD > RCTEKST.TXT
IMDA CPM56K.IMD > CPM56K.TXT

I then extract the *.RAW Files (Sector Dumps) so I can get directory listings with cpmtools.

Code:

IMDU GAMES.IMD GAMES.RAW /B /E /D >> GAMES.TXT
IMDU MBASIC521.IMD MBASIC521.RAW /B /E /D >> MBASIC521.TXT
IMDU WORDSTAR.IMD WORDSTAR.RAW /B /E /D >> WORDSTAR.TXT
IMDU RCTEKST.IMD RCTEKST.RAW /B /E /D >> RCTEKST.TXT
IMDU CPM56K.IMD CPM56K.RAW /B /E /D >> CPM56K.TXT

If you have a bootable 5.25" Floppy, you can try using BIN2IMD to write a 8" image
from the .RAW image.

Code:

    BIN2IMD input-file output-image [option-file] [options]

    BIN2IMD X.RAW X.IMD DM=3 N=77 SS=512 SM=1-8 /1



Where the Options are:
opts: /1 - 1-sided output
/2 - 2-sided output
/C - write Compressed sectors
/U - write Uncompressed sectors
/V[0|1] - Verbose output
C=text | @file - image Comment
N=#cylinders - set Number of output cylinders
DM[s]=0-5 - track Data Mode
SS[s]=128-8192 - track Sector Size
SM[s]=n[,n-n][n.#] - track Sector numbering Map
CM[s]=n[,n-n][n.#] - track/sector Cylinder Map
HM[s]=n[,n-n][n.#] - track/sector Head Map

and

DM= sets the Data Mode, which must be one of:
0 = 500 kbps FM \ Note: kbps indicates transfer
1 = 300 kbps FM > rate, not the data rate,
2 = 250 kbps FM / which is 1/2 for FM
3 = 500 kbps MFM encoding.
4 = 300 kbps MFM
5 = 250 kbps MFM

SS= sets the Sector Size, and must be one of:

128, 256, 512, 1024, 2048, 4096 or 8192.

See: Imagedisk's IMD.TXT for more details.

Anadisk can be used on the non-booting 8" to locate the number of Sectors and tracks.

Try these updated definitions. Remember, that when trying to access the Floppy's data (RAW SECTOR DUMP)
the first two tracks can be adjusted by 2048 bytes (16 x 128) to make Track 0/0 & 0/1 the same size. I use dd to
copy Track 0/0 to a file, then append the remaining total file to get Track0 Side 0 & Side 1 both at 4096 bytes.
This allows cpmtools to access the data files. cpmtools does not like a SD first track and DD second track even
though it is supposed to work correctly using the offset (SOFS) value. OFS is basically the Boot Tracks while
SOFS is sector offset to the Directory.

Code:

As an example I started with CPM56K.IMD and created the CPM56K.RAW file, then copied the first
2048 bytes to a new file. Then appended the complete file.

Code:

$ dd if=CPM56K.RAW bs=1 count=2048 of=LKM56K.RAW conv=notrunc
$ dd if=CPM56K.RAW bs=1 seek=2048 of=LKM56K.RAW conv=notrunc,sync

321536 Mar 7 09:17 LKM56K.RAW

2048 + 319488

319488 May 6 2017 CPM56K.RAW

Code:

$ cpmls -f rc01 -D LKM56K.RAW

As Behind the doors and with lot of help from Larry, we accomplished new definitions for the software program 22DSK142

Had a lot of struggle to define the 8 inch definition and in the and we worked out that it is a software issue of version V1.44
Formatting and writing the 8" definition for several 8" formats with v.144 is no problem,
but reading 8" formats of several kinds of definitions machines does give read errors.

There for, for 8" do NOT use v1.44 but instead 22DSK v1.42

Here are the new RC702 Piccolo CP/M Definitions.
22 DSK v1.42 (22DSK V1.44 does not work for 8"Definition,read failure)

There is been made by me, a mistake in the 22DSK142 Definitions RC702 5,25 as well as 8"

ORDER SIDES instead off CYLINDERS.
And therefore the OFS must be 4 instead of 2.That was the trick why it would Not work proper before with ORDER CYLINDERS
And as I got a good DIR with cyl and a small text-file looked ok thought this was ok BUT, a large file did go wrong.

DIR is at CYL: 2 Side: 0 Sect: 1 , So CYL 0/0, 0/1, 1/0, 1/1 counts offset of 4.

With this settings and fully tested all files these are the right settings.
Still need to figure out RC702 8" SSDD , As RC702 also can format 1 sided disks.

With these settings I also can transfer files between 5,25 and 8" disks.

As the RC700 Emulation program uses the sector order 0-14 instead of 1-15x512, you have to use
RC71 to read disks made with Images from RC700 Emulation, Then transfer to RC70 disks.
Remember also to use the 500->250K setting in ImageDisk 118 software to write on 360k 48TPI drive,
when using Images made with RC700 emulation.

As I received a CP/M 2.2 Boot disk with a RC700 CP/M LOADER disk, that disk transforms The RC702 to an
8 Inch SSSD 26x128 drive so it can boot the RC700 CP/M disk.
There for I added RC76 to read this RC700 CP/M 2.2 vers. Disk.

Mark Definitions work under 22DSK142.

What's the reason for using 1.42 instead of 1.44/1.45? The author would like to know.

MauriceH · Mar 28, 2021

Chuck,
1.44 does not seem to read the 8 Inch disks proper, just fails.
To rule out a typo mistake, I just copied again CPMDISKS.DEF from 142 to 144 dir, so exactly the same.
Just to be sure, I checked just again.

I used the same definitions RC72 on both versions 142 and 144, see results.
1.42

1.44

MauriceH · Mar 28, 2021

Hi Chuck,

Out of curiosity I tried in 1.44 to copy a file CPM-> DOS
That though seems to work!
Typical the option 6 Show Directory listing does not work.

But still think it unsafe to use version 1.44 for reading 8"disks.
Hope it will help to find the "bug" in 1.44

Chuck(G) · Mar 28, 2021

What does your DISKETTE.CFG file look like for 1.44?

MauriceH · Mar 28, 2021

you got a PM to send the complete 22dsk144 program to you, so you can look at it.

Chuck(G) · Mar 28, 2021

I'm really interested in your DISKETTE.CFG file, actually.

MauriceH · Mar 28, 2021

You mean the CPMDISK.DEF (..NOI) File?
Definitions I use are to be seen above.

DISKETTE.CFG I have not. The listing 22DSK144 files.
