Have you tried formatting the disks on your TS803 and then using Media
Master to read/write them?

Yup. Uniform-PC by MicroSolutions. I can point you at a vendor if
local dealers don't have it ..

Subject: Re: Osborne Executive -- Part Missing
Message-ID: <1991Oct16.082033@IASTATE.EDU>
The Osborne Executive has two long connectors on each side of the
motherboard. The connector on the left is for the memory board. The
board is positioned upside down on spacers. If you lift the board off
you will find two rows of 4164 rams chips and some TTL support chips.
If you are missing this card your in trouble. I am working on a
replacement (see below), but I won't count on it right away.
The connector on the right was used for the hard disk interface card.
(Did I really say HARD DISK?) Yes, a very few Osborne Executives had
hard disks in them. I have not seen one, but a co-worker said he once
had one. ( I am trying to find out more about this.)
You didn't give very much information on the symptoms on why your
machine would not boot. I am willing to help you, but I'll need more
information on the trouble.
Since I used to service Osbornes (and still do) I have the service
manuals and schematics to the Executive. I am working on upgrading my
Executive to add the additional four banks of memory, a larger boot
EPROM to add additional routines to the BIOS and replacing the 5 1/4
inch disk drives with 3 1/2 inch HD drives. (The Executive was built
with easily expandable hardware.) I almost have the pc layout of the
memory board done. I am still trying to track down the Osborne
Technical Reference manuals to get the BIOS listings to do the EPROM
and disk drives.
Even though I don't mind altering my Executive, I would like to find
one I could experiment with. If anyone has an Executive they don't
want anymore I would gladly pay shiping and handling.
The Black Box BBS, formerly a Fidonet based system, is now on Usenet and is
available 24 hours a day, 365 days a week, with a full newsfeed. The two
lines are 713-480-2686 (V32/V42/V42bis/HST) and 713-480-2685 (2400 MNP-5).
I am a long time CP/Mer, from waaay back in the 70s, and am planning on including a section of my favorite CPM programs. I will also continue to support MSBBS, the Fidonet BBS I wrote in Turbo Modula-2.
The old Kaypro bit the dust, and I have replaced it with a 486, SCO Open Desktop, and am really enjoying it. In fact, I would like to give my old CP/M systems a good home. If you want one, give me a call voice at 713-480-2684.
1 Televideo 816, 32 meg hard drive, up to 16 users, $250
1 Televideo RWP, *4* Z80's, each with 2 serial ports, perfect for a BBS! $200
2 broken Televideo 800s, no floppies (diskless), $25/each
If you buy allof the above, $500. Full docs and LOTS of software will be
included, along with LOTS of spare boards, chips, etc. The system currently
is set up for 5 terminals, the 802 and the RWP with 4. Just add more and
turn them on in the config file for up to a 16 user CP/M system!
I also have a SWP ATR8000, with 4 floppies (2 5 1/4" ds/dd, 2 8" ds/dd), also with full docs, tons of disks, et al, $300. If you want the COPOWER 88 ramdisk
(1 meg) which can also run CP/M 86 and MS/PCDOS (I have both for it), $200.
It is GREAT for exchanging from CP/M to DOS, as you can use the DOS2CPM, and
CPM2DOS and CPMDIR commands in DOS to move files around! Full 973K TPA in DOS!!due to the lack of screen memory!
Buy both the ATR and the Copower and I will throw in an Atari 800 and a
Depends on WHICH hard drive it is - Seagates don't like being upside down as
a general rule, Micropolis and Maxtors generally don't seem to care....

A quick look at the schematic of a PC FDC controller would tell you
that regardless of the chip's logic, correct or not, the PC FDC
controller can't read or write single density anyway, since there is
no logic to change clock frequencies or modulation.
