Hi all,
I picked up a very nice Osborne 1 from a local thrift store yesterday. The
system powers up. Everything looks good. However, I don't have the boot
disk. I tried the CP/M boot disk from my Kaypro II. No good. If I
remember correctly, the disk drives on old CP/M machines are not compatible
with each other even though the binaries are. It looks like that I need an
Osborne formatted CP/M boot disk. Does anyone know where I can get one?
Also, it would be nice to get a CP/M communication software on an Osborne
formatted disk so that I can start transferring other CP/M software to it.
In the same store, I picked up a Peripheral Expansion Box for my TI 99/4A.
It comes with 1 floppy disk drive, 32K memory expansion, serial adapter,
and flex cable adapter. However, the fuse and the cap that holds the fuse
in place are gone. Does anyone know the specification for the fuse or know
where I can get a replacement for it and the cap?
Any help is greatly appreciated.
George

Contact Don Maslin <donm(a)cts.com>om>. He is the keeper of the Dina-SIG
System Disk Archive. He is a great source of system disks for CP/M
machines. He usually charges $3 for the first disk and $1-2 for each
additional disk.
I got some system disks for and O1 from him early this year. He is and
excellent resource and a righteous dude. Without him and the system
disk archive many otherwise working machines would have ended up in
the landfill.

Hey! I currently have a similar problem. I brought a Kaypro II home
recently (last week? I've forgotten already) and although it had a boot
disk in the drive, it wasn't an OS disk, and I can't format disks or
other boot disks. And the disk that was in the drive (a pirate copy of
WordStar) is flaky.
I transferred FORMAT.COM and SYSGEN.COM from my TeleVideo system, but
they gave me little more than the (C)1982 TeleVideo Systems message
before hanging the Kaypro. <s>

Seek out the comp.os.cpm FAQ. There is information in there on how to
get boot disks for CP/M systems. I'm still hoping to find someone with a
Kaypro II locally. I generally sit on these things for a while to see
what turns up before becoming really active in seeking things out.
In case you can't get the Osborne disk anywhere else (doubtful) I do know
a chap who ran a BBS on an Osborne until recently. He should have what
you're looking for. I could bug him to send you one if you send the
relevant information to me in e-mail.
Also, it would be nice to get a CP/M communication
software on an Osborne
formatted disk so that I can start transferring other CP/M software to it.
You should be able to also xfer software to the Osborne with a utility
for the PC called 22disk. Get it at:
oak.oakland.edu: /pub/msdos/diskutil/22dsk142.zip
I've used it a couple of times myself (in fact that's how I got those
files from my TeleVideo to the Kaypro) but you need an IBM-compatible PC
with a 5.25" disk drive (preferably 360K) which is something I don't have.
I actually had to open up my father's PC to plug in a 5.25" drive just
for that one operation. :/

Heh. This also sounds familiar. I have a CBM 2040 drive, sans fuse and
cap. I know at least one of the drive units works, as I got a directory
from a 1541 disk on my PET while holding a screwdriver
in the fuse
socket. Don't do this at home. :)
Any help is greatly appreciated.

The Kaypro is a pretty nice computer we have a Kaypro-10 at work
(locked away in storage till who knows when). Good video bios, no
hi-res like the Televideo but the terminal emulation was ok, (ADM 3A
compatible, I think). Can run Worstar on it as well as dBase II also a
handfull of simple video games and a drawing program (SCS draw). I
might have the disks under my desk at work... ;-)

I would get a panel mount fuse-holder from Radio Shack and replace it
(that is if the fuse-holder caps are incompatible), fortunately many of
the PET/CBM fuses are not PCboard mounted.

Mind you, I'd like to also get more memory for it somehow. I'm still
running on 8K. Does anyone know if I can get some other chips to plonk
in the sockets to give me more memory?

I think the power supply on my Kaypro II is anemic or something. The
display shudders when the drives are accessed, and scrolling in WordStar
causes the characters to not be fully drawn during the scrolling. Kind
of like a "black static" blotting out the green. That latter problem
might be normal, but the compressing screen on drive access thing looks a
little worrying.
How do I get the terminal emulation running? Do I need the boot disk for
this, or is there some mode I can turn this thing on into, to get it to
act as a terminal?
I'd like the same kind of info on the TeleVideo, BTW. Mine is a TPC-1,
the cool luggable one. I've got a copy of MDM803 that works on it, that
was on the disks I got from the former owner. I also started writing my
own terminal software for it (VERY basic, where I left it) and I still
hadn't figured out the serial port hardware. I had to run my program,
quit immediately, then run again or the system would hang. Basically, I
need manuals for the TeleVideo quite badly. I'd especially like to know
how to access the graphics... I have the TPCIDEMO program and a couple
of other graphics demos, and the graphics are really impressive for that
class of machine!
Oh, BTW, I opened the Kaypro up, and it looks like there has been a
modification made to it. The chip at U87 (markings were DM74LS390N) had
a couple of wires soldered to it. Pin 1 was pulled out out of the socket,
and a wire was soldered onto it connecting it to pin 6. Pin 9 was
removed entirely. Pins 12 and 15 were also connected with a wire.
Does anyone have any idea what this is? Is it a modification of some
kind, or was it a correction made at the factory?
