[comp.sys.apple] UDC, SCSI, InnerDrive, No-Slot-Clock, etc...

tp@cbnewsm.ATT.COM (thomas.a.pierce) (08/19/89)

      I'm hearing about the UDC/Laser 800k drive combo. eating disks.  Is
this -ONLY- when used with an innerdrive or does this happen 'universally' :-)
Will it screw up a scsi drive (homebrew)?  Is this only with the card or does
it also happlen with the 128ex built-in UDC?  Does anyone out there have
good/bad expiriances with the No-Slot-Clock?  (Anyone running a proline with
one?)
     -Tom

The No-Slot-Clock is not compatible with ModemWorks; thus, it will not work
with ProLine.  According to Morgan Davis, the NSC doesn't return the correct
information to the input buffer when the time is asked for.  More spefically,
the problem is with the day-of-week and seconds not being returned in the
proper ASCII format.  It *does* work with ProDOS, although it does not follow
the specification exactly, and because of this could not be supported under
ModemWorks.

I'd avoid it if possible.  If you're really pressed for slot space, I'd
suggest getting a multi-function card (AE has one) that would allow you to
combine a serial card and clock.  The No-Slot-Clock requires every version
of ProDOS you use to be patched, which is fine if you have a hard drive, but
gets to be a bit of a pain if you're restricted to floppies.

I don't know about the No-Slot-Clock specifically, but the Smartwatch, which
as far as I know is functionally equivalent, is perfectly compatible with
ModemWorks.  I have been running OBBS (a ModemWorks based Shareware BBS system)
on a IIe with a Smartwatch ic for over a year with no problems.  It is true
that ProDOS has to be patched to find the clock, but only on those disks that
contain programs that need to tell time!  You do have to use a different
command from the built-in &TIME, but you get the same information.

The drive is a little weird (it can cause soft block errors if you start to
while it is just about to stop whirring), but mostly okay.  Slow though.

There appears to be some sort of conflict with the UDC and the InnerDrive
controller; when I use one and then the other, the computer kicks into slow
mode.  Note that this does *not* occur when using GS/OS; only ProDOS 8 and
ProDOS 16.

I have not had any problems with the InnerDrive by itself; just the lousy
3.5" drive.  I plan to buy a used AppleDisk 3.5 soon...

My best friend is running GBBS Pro v1.3j on an Apple IIe with the following
configuration....

1.  Super Serial Card connected to an ImageWriter II
2.  Epic 2400 BPS Classic II internal Modem
3.  Nothing, but 832K on an AE RamWorks II in the Aux slot
4.  Mouse Card (not yet installed)
5.  Central Point UDC w/1 3.5" Drive
6.  Apple Disk Controller Card connected to a DuoDisk
7.  Chinook 40 MByte SCSI HD w/Apple SCSI Card

SMT No-slot clock.  He's had no problems that I know of (and I think I'd know.)

I've been using a UDC/Laser 3.5 combo for the last year and a half with
varying degrees of success.  I've never had it cause a harder to crash (i.e.
my CMS s2/20s) but it has reached out and destroyed 3.5" disks at one time or
another.

I will add this however:  Since I've moved it to my dedicated ProLine system
and took off the 5.25" disk drive from the UDC it handles the 3.5" drive with
nary a problem.

If I had to do it over again I'd blow the UDC off.  They're junk in my book
but capable of (slowly) backing up a hard drive.

You probably forgot to mention that he has an Enhanced //e (with a
65C02) but not a W65C802.  I see that he doesn't have a TransWarp.
I "think" the UDC would have trouble with an unEnhanced //e.  But
so does everything else (software, at least), it seems.

But at least now I know the UDC works with the Chinook on a //e.  I've
been wondering if my UDC problems would escalate even further with a SCSI
drive.  Maybe I should sell the Apple 3.5ers, but I hate to lose that Mac
compatibility in removable media.
