Hi all

Has anyone got the 22DISK definitions for Lifeboat Associates CP/M 2.2 on the Model II?

Cheers
JonB

Edit: I found these but they don't appear to work:


BEGIN TRS4 TRS-80 Lifeboat CP/M (256 bytes/sector) - SSDD 8" - 256 x 26
DENSITY MFM ,HIGH
CYLINDERS 77 SIDES 1 SECTORS 26,256
SIDE1 0 1,10,19,2,11,20,3,12,21,4,13,22,5,14,23,6,

BSH 4 BLM 15 EXM 0 DSM 242 DRM 127 AL0 0C0H AL1 0 OFS 2
END

BEGIN TRS5 TRS-80, Lifeboat CP/M - SSDD 8" - 1024 x 8
SEE COM8

BEGIN COM8 Compupro (Viasyn) 8/16 - SSDD 8" - 1024 x 8

The COM8 definitions seem right, according to ANADISK, which is telling me:

High Density
Sector size 1024
Sector IDs 1-8
Interleave 1:1
CPM directory at Cylinder 2

I also followed Larry's advice here (http://torlus.com/floppy/forum/viewtopic.php?f=2&t=899), in part, and discovered that the values in the COM8 definition seem to match what is in the Lifeboat DPB. On attempting to read the directory with 22DSK144, I am seeing "Sector not found" for Cyl 2, Side 0, Sect 1. However, ANADISK does see (and recognise) the directory.

I did try with SIDE1 0 1,2,3,4,5,6,7,8 but that didn't work either. I assume the interleave 1:1 is a default? Larry's comments imply it affects the SKEW setting (there's none in the COM8 defs). So I added SKEW 1 to the definition but that's not helped either.

JonB,
The SKEW for the COM8 Definition should be 3 and the TRSx 9.

The current cpmtools (& libdsk) definitions I have are:

BEGIN TRS4 TRS-80 Lifeboat CP/M (256 bytes/sector) - SSDD 8" - 256 x 26

BSH 4 BLM 15 EXM 0 DSM 242 DRM 127 AL0 0C0H AL1 0 OFS 2
END

Can you create a IMD or TD0 file of the floppy?

I can't upload it, it's too big even after zipping.

However, if you have a copy of the Maslin archives, it's the TD0 file at [archive root]/1995/tandy/trsiilbt.td0

Well, you know that if you're a registered user of 22Disk, Sydex will work the definition out for you, free, gratis. All that's needed is an image.

Of course, if you're not registered, you're on your own.

JonB

How do I do that, Chuck? Their web site just offers services, no "register". Or download for that matter...

There's an email link--use it?

JonB
February 20th, 2016, 04:31 AM
Obvious though it sounds, I didn't look for an email address because the menu says it is 20 year old software, so I don't expect any contact details to be still valid...

Edit: After hunting around I found info@sydex.com. I'll drop them a line. [Edit 2: Done.]

The menu is almost never updated--it's just a shell program to invoke individual utilities. I suppose we could rebuild the whole thing, but there's no point to it.

What we do update is the definition file--pretty often.

We? Are you associated with Sydex, Chuck?

Uh, yeah--since at least 1987.

Ok.... I didn't know that.

Anyway, I'll be sending you a registration fee today. According to document linked above, you're the author. Awesome work, Chuck. :)

(Edit: sent.)

If you need a definition worked out, as a registered user, just send an image or a physical disk and we'll work it out, add it to the database at no charge--for as long as we're around.

Thanks!

Thank you Chuck, I have sent images to your info email address and they have replied to say they forwarded them to you.

One of them is from the Maslin archive, it is the Lifeboat Associates boot disk. The other two are IMG and TD0 images of a disk that I formatted, SYSGENned and copied some files to on the Model II. I think it is a different format to the Maslin image.

I'm looking to use 22DISK as a transfer tool, so I need to be able to read and write from/to these formats. The non Maslin images are the priority.

Regards
JonB

I'll have a look at them and also see if they'll boot on my Model 16 (they should).

No need. 22DISK145, which you sent me, seems to work fine! Hurrah!
