Well, if its DEVICE 8 ... then simply type DIRECTORY.
If its not device 8, do this : LOAD"$",(device#) and when its done type
LIST
Thats how my setup works anyways ... PET 4032 - tested it with 8050 disk
drive, 2040 disk drive, 2031 disk drive and SFD 1001 disk drive

Aren't the drives in a PET dual drive unit 0 and 1? So to save to the second
drive it would be SAVE "1:filename",8.

As for a guess on the two switches, one may be going to the diagnostic sense
line and the other to reset. This can allow you to do a "soft reset" on a
Pet.
On to the drive problems:
*** Foggy Memory Mode ON ***
Your drive will have a device number, probably 8. The individual drives
within it are refered to as drive 0 (right-hand) and drive 1 (left-hand).
To get a directory on a Basic 2 computer:
LOAD "0:$",8 or LOAD "1:$",8
If that doesn't work, try other device numbers from 9 to 15.
To send a command to the drive (initialize used as example):
OPEN 15,8,15
PRINT#15,"I0"
CLOSE 15
The characters in quotes are "I" as in "I wish this drive worked", and 0 as
in my bank account balance....
Other commands are:
N -- "New" which is Commodore lingo for format
V -- Validate (get rid of problem directory entries)
C -- Copy
R -- Rename
I won't go into detail other than to say that you need to specifiy which
drive (0 or 1) you are referring to.
To load a file:
LOAD "0:MYFILE",8
To save a file:
SAVE "0:MYFILE",8
LOAD and save will default to PRG type.
Finally, to get the status of a drive:
A$="":OPEN 15,8,15 : GET#15,A$ :PRINT A$ : IF A$<>CHR$(13)THEN NEXT
(I have no idea if that last statement will work. It's been a LOOOONG time.)
If you have Basic 4.0 in your Pet, it is much easier. You should be able to
get a directory with:
DIRECTORY D0
or
CATALOG D0
Disk status should be available with:
? DS$
at least I think it is DS$....
*** Foggy Memory Mode OFF ***

Well ... if it worked with an 8096 it should work with any PET.
I had an problematic 2040 drive at one point ... it was turning on and
checking the drives, then the lights would flash (all of them) like 6 times,
stop, then do it all over again. I am not sure what chip it was, but I
replaced the 6502 and I think the 6522 chips and all was fine. Like I said,
I replaced both chips (pretty much pilaged one of my 10 commodore 1541
drives for them) .. so I don't know which was actually problematic.
Anyways, see if you can't get to a old 1541 or something you don't use, but
know works correctly. Swap out the 6502 at the very least .. more chips if
they match.

Actually, LOAD "$0",8 for drive 0, LOAD "$1",8 for drive 1 and LOAD "$",8
for both drives. Your syntax is correct for loading programs, though.

Ummm...
I personally don't know of any adapters to use an 8050 with a Plus/4 ... and
there would be little point anyways.
There was an adapter or two made for the C64 .. but I forget its name and I
know that they were a bit hard to find. I think that you plugged an adapter
into the cartridge port and a cable came out to attach the disk drive to.

With an IEEE-488 interface it's possible, but Commodore's IEEE cart-
ridge disables the serial bus in order to enable the IEEE bus. I
believe André Fachat has a fixed ROM though that lets you use both.
IEEE drives are quite a bit faster than stock serial drives, and the
8050 can put 0.5MB on each disk.

The Interpod-1 does that.. IEC -> IEEE-488 (but it's agonizingly slow)

Ville,
What's Interpod-1? I saw on Hendrik Lipka's site that he had an
interface for a 2031 and was going to put up the schematic
someday, but I this seems like just a lick and a promise for the
time being.
Thanks,

The PET has two EPROM slots available, one at $9000 and the other at
$A000. You probably can't tell which is which at a glance. Try
SYS 36864
or
SYS 40960
and see if you get anything. Possibilities that I know about that
your eprom might be-- 1) the micromon assembler 2) a "dongle" for
WordPro (word processing program by Steve Punter that is very
similar to PaperClip 64) 3) the "Command-O" BASIC programming
extension kit. 4) A "medium-res" graphics package (forget the
name)
You could get extender boards for the motherboard so that you could
have two eproms plugged into the same socket. If you have those,
they will be wired to a switch. If you attempt to switch on the
fly (without powering down) you will most likely hang the machine.
As another poster said, the two buttons are probably reset
switches. One will probably do an NMI reset (similar to
RUN/STOP-RESTORE on a 64) and the other will do a hard reset
back to the power-up screen.

drive with my c128d i use the sipod link system , which is a prg to run
on 8000/4000 and a cable from cbm user port to the c128 serial port .
will copy etc for anyone who sends me snail mail addy

You find a description on funet (see the link under the IEEE pages
on http://www.6502.org/users/andre)
And it is quite fast. I decided to use this adaptor instead of some
proprietary fastloader (I have a VC1541 with IEEE488 interface and
one without)

That's my interpod.. ;-) It's a bit battered as it was used in a
vocational school before I got it.
There's two IEC ports and one IEEE-488 port. I think it also has a
female d25, but I don't know what that's for.. (maybe parallel
printer?)
It works very solidly, but is extremely slow.

It's a RS232 port, you can send data there via device number 4. Don't
know it's default settings, maybe 300 baud. I couldn't figure out how to
receive data from that port, maybe it's not possible. Maybe I should
scan/type in the little doc sheet that came with the device?
My Interpod looks like new, maybe because it has never been opened and
used until I got it some months ago ;-) It had a broken IEEE port
though, I found that one trace on the PCB was open. The seller told me
that this is normal for UK manufactured hardware, and we both were happy
what an easy fix it was.
> It works very solidly, but is extremely slow.
Yes, damn serial bus.

Ok, then I presumed right. Is it really a female port? My interpod is
100km away.

Please do!

Hmm... :-)

No fastloaders either. :-(
Pity my parallel IEEE-adapter sucks. Made by Handic Software (it's the
SuperBox IIRC). Very fast indeed.
It transfers fine for a while but then it starts giving errors. Maybe
a grounding problem? (does anyone have docs for that beast?)

Mine was only 2m away ;-) It's a male DB25 port, the pinout is
1 GND
2 TXD
4 RTS
5 CTS
8 DCD
20 DTR
22 RI

May take a while, but I won't forget it!
BTW, the RS232 port's standard settings are to send data for IEC #4 with
parameters 1200,8,N,1 without ASCII conversion. There's also the
interpod command channel on this device number, but at SA 31. You can
send commands there for changing the RS232 and command channel to
another device number and set RS232 parameters.

Ok, I assume you'll notify us here in the group. :-)

Hmm, was this the case with CBM's IEC printers too or did they use 15?
