After the US Postal Service fiddlyfarted with a package for a month, I've
finally got everything together.

bags of non-static-sensitives: check

David -

Are there additional kits available for immediate
shipment?

Alternately, any interest in selling PCB's with SMT
only?

I'll have some kits available immediately as soon as I burn some more CDs.
I haven't heard from anyone yet who wants a plain PCB with SMT.  I'm not
sure what the sale price would be.

Greetings all,

  I assembled the P112 over the weekend, installed the card in an old
atx case that my daughter had left over when I built her a 3 GHz Celeron
system - works out nicely.  I simply drilled holes in the side internal 
panel of the case and installed it with standoffs.  The case is perfect 
since it has front bay slots for 2 3.5" drives, 3 5.25" drives (for two 
5.25 floppies and a CDROM).

   The front panel reset switch must be thru a high resistance as it 
didn't do the trick for the reset function, but the power on/off switch 
on the front works great and is much larger.  I still need to deal with 
some switch for power as the atx supply I have does NOT have a power 
switch on the rear.

  I jumpered the green PS-ON connection to ground on the ATX power
supply connector, then tapped into 5 volts via a fan power adapter I had.

  Troubles encountered:
    1 - read the manual - I had weird booting indications on the floppy
(I even corrupted the boot floppy and had to recreate one once or twice)
when the nvram settings were NOT set first in the monitor ROM.  So, you
may wish to be sure you can create a boot disk from image before you
destroy the one provided.  The ultimate issue, however, is getting the 
floppy cable hooked up correctly.  I had it totally switched around, 
putting the "twist" in the wrong place.

  2 - nvram doesn't seem to be holding info - I will need to check to
make sure the battery is good or perhaps installed backwards :( (update 
- the battery was dead as a doornail, but I had spares around and a 
replacement did the trick).

  Plans for the future - boost ram to 1 meg, add GIDE, 5.25 floppies, 
CDROM, and either a hard drive or CF slots.

Great little kit !!!  Now I need to refresh my memory on cp/m and read
up on ZSDOS.

This by far the easiest way to go, especially if you intend to go beyond a
basic floppy-only system.

Bummer.  Power strip?

The defaults for the NvRam are set for the 'standard' PC-type 3.5" floppy
drive.  In most cases, you will not have to do anything to the NvRam floppy
settings.  In fact, it will normally boot fine from floppy without ever
setting the NvRam data.

I'm standing by, ready to supply a GIDE (or two) at any time!  :-)
1MB RAM and 128MB CF-IDE adapters also on hand.

Grrr!  That's the second one I've sent out with a dead battery.  I'll go
back and check all the kits in stock for this problem.

John -

I also just completed a P112 and though I'd share my
experiences...

David must have received a bad batch of batteries, as
mine was stone dead too.  Also the tant caps I
received weren't marked with polarity in any standard
fashion that I've ever seen.  I ended up using a cap
meter and measuring leakage to determine polarity. I
have notes at home as to the polarity, but can't
recall at the moment.  Otherwise the kit went together
easily and was well packaged and documented.

Terry G. was a tremendous help, and is an all around
nice guy.  He is very quick to respond and very
supportive of his products.   I'd strongly encourage
you to consider the GIDE, and I especially like his
compact-flash option.  It works beautifully, and the
Banked bios is cleanly integrated with his 1mb
upgrade.  I'm currently running dual GIDE's, with 2 cf
media on the primary and a CD on the secondary.  I'm
considering putting another CF on the secondary as an
"offline" backup.

Now to get all of my old S100 software reinstalled on
the "new" platform!

I updated the docs to state that the positive lead on those color-coded
caps is on the right when you hold one with the white spot facing you.

Despite the strange marking system the tant caps did
measure very nicely both for value and leakage.

I do a lot of repair on older (vaccum tube based)
equipment.  My trusty Sencore LC-53 has paid for
itself many times over!

Greetings All,

  Terry, I haven't forgotten you - just trying to spread out my "fun" 
expenses over a few weeks so the budget doesn't look ugly.  I will most 
likely get one GIDE with cf card and interface.

  I did, however, obtain a 5.25" floppy drive for my P112 and am trying 
to get the board to recognize that it has a drive connected to P10.  
Before installing, I popped it in my desktop PC and was able to read an 
old 5.25" floppy drive and run scandisk, so I know the drive is 
functioning.  However, the setup of the nvram doesn't have an option for 
drive 2 and 3 and there is no LED activity when the system comes up to 
the monitor.  If I proceed and boot, ZSDOS doesn't know about any drives 
but A & B.  Any pointers??

thanks,
john

Additional info:  I have the drive connected on the end of the cable so 
it will be seen as drive 2 instead of drive 3.  Also, I pulled thr P11 
jumper to flush the nvram, just in case that needed to be done so the 
system would see the additional drive - no joy.

Take as long as you want, John - I'm not going anywhere.


Your problem is that P10 is not recognized as a 'valid' floppy port by the
OS you're using.

First of all, the Boot ROM has no way of accessing any floppy except Drive
0: (or A:, or whatever convention you use) and it is on P9.

Secondly, the Z-System BIOS that comes with the P112 cannot operate a floppy
via P10 in any way - it only knows about TWO floppy drives, 0: and 1:, and
both are on P9.

There ARE provisions in the BIOS for using 5.25" drives, but the only way to
do it would be to connect the 5.25" drive as drive 1: on P9 and use the Boot
ROM NvRam Setup to define drive 1: as a 5.25" drive.  Whatever is set in the
NvRam is what is used by the BIOS, so the BIOS would then see drive 1: as a
5.25" drive.

As for using more than two floppy drives, the supplied BIOS cannot do it.  I
suppose that's why there are no setup parameters in the NvRam for drives 2:
and 3: - makes sense to me, anyway.


The good news is that, when you DO get the GIDE, it comes with a fantastic
BIOS - in addition to other goodies - that allows 4 floppy drives to be
used, in virtually any combination of 3.5", 5.25", or 8".

It can read/write floppy disks formats from many different machines, too.

This type of flexibility would normally eat a lot of the TPA and make for a
huge BIOS.  That's where the memory banking comes in to play.  Much of the
added functionality is in banked memory, so the TPA can remain fairly large.


Standing by for more...

Terry

Thanks Terry - in reading the P112 manual again I could sort of read
between the lines and see that there were no provisions for drive 2,3. 
Until I get a GIDE et al., I will play with the 5.25 drive as drive 1.

tnx for the lightning response.
