[comp.sys.ibm.pc] Sota 286i and 386i Accelerator Cards

gec@cscosl.ncsu.edu (Errol Casey) (03/19/90)

I am interested in collecting comments on either of these IBM PC
accelerator cards (Sota 286i / 386i).

Questions:

(1)  Can you add additional memory to the accelerator card? How much.
(2)  Does the 386 use a 386 or 386sx? Does it come with 32bit memory?
(3)  Any compatiblity problems?

I have a SOTA 386si installed in a Zenith Z-159 (XT-level PC). Installed
it in early January, it ran well for 5 weeks, then started acting up --
I'm not clear if the problem was the card or the Zenith installation; they
have to "tweak" the board in various ways to optimize it for different systems,
and mine came untweaked originally. Anyway, it's back in my machine now & all
seems well. I have a Norton SI rating of 15.6 with the card installed & the
cache turned on. Turn caching off so you're running in the "native" (???)
386sx mode & the Norton is 2.8. They supply software drivers for all sorts
of caching; before my cad went in, I had to uncache my video & BIOS to get my
machine to run any software --WP50, LOTUS, etc. Everything works with all
caches turned on now, so they did something while they had my board.
   I have 1.2 megs of memory. It's all expanded memory (EMS4.0) & runs under a
Sota EMS driver. 256k is a hard drive cache (also SOTA software) & works ok.
Not sure where all my other EMS memory is, but LOTUS uses it.
   The 386si is a half-card. SOTA sells an add-on called Memory 16i which
plugs into the 386si & adds up to 8 megs of 1 mb SIMMS. They claim OS2
compatability (extended memory) or EMS 4.0 (expanded) capability - you
could use with DesView (they have a driver), etc. I plan to buy when I can
afford.... I'm not sure if the 16i will disable my other memory. I can reason
to an argument that optimum performance would dictate that the 16i memory
should take precedence -- 16-bit BUS, etc. Maybe I can move my present
memory chips to the 16i. I haven't gotten that deep into it yet.
i
   Anyway, all my software runs with the board. The folks at SOTA seem
responsive to inquiries, helpful, etc. No hassles concerning repair/modifi-
cation. I like the performance enhancement. I run WP50, SPSS-PC, LOTUS,
DBASE, ProComm Plus, Harvard Graphics, Norton Utilities & Commander, and
the WP Library shell program. Microsoft Paint, too. Maybe some others, but I
can't think of any. All run with no problems.
   I'm a little apprehensive
about reliability right now -- spooked by my earlier experience, I guess. But
everything is working fine right now. I have some 350+k LOTUS files that used
to take 1/2 hour to sort; they sort in less than a minute now.

In its standard configuration, both SOTA's use the existing PC's memory and
I/O peripherals. There are optional boards that allow you 
to add up to eight megabytes of memory and a 16 bit floppy 
and hard disk controller. However, with all the options added, 
its cheaper to buy a new machine.

>(2)  Does the 386 use a 386 or 386sx? Does it come with 32bit memory?

The 386 is an 386sx. It sells for about 460.00 open market with no
options.

>(3)  Any compatiblity problems?

The Sota will work with 8086 PC's while the Intel 386/PC will only work
with true 8088 IBM PC compatibles. The Sota can also run OS/2;
however, it is obvious to me that if you want to run OS/2, you 
have to buy all the options.

The Sota 386SX is a better, later design than the Intel 386/PC. 
Everything on a Sota fits on a half card while the Intel is a full card. 
The Intel has no 16 bit floppy/ hard disk controller option. My
bottom line is what do you get for the money. The Intel 386/PC can be
easily bought at a discount. The Sota was not as available as the 
Intel the last time I checked and the Sota was not bundled with 
any 32 bit memory. In the past, some vendors bundled Windows/386 with
the Intel 386/PC.

Additional note: it seems that Intel and Sota play different games: 
Sota attempts to make their product conform will all software. 
Intel attempts to make all software conform with their product.
If a software developer conforms to the latter, the software should
work on the former.

No, not directly on the card.  The SOTA Memory/16i card, released in the last 6
months or so, allows you to add up to 4MB (SIMMS), and cables into the
accellerator card.  There's a 4MB duaghter card (for a total of 8MB) if you
want more than 4MB.  The 16i memory is considered primary memory since its
obviously faster; any existing memory is used to backfill.

> (2)  Does the 386 use a 386 or 386sx? Does it come with 32bit memory?

Dunno.

> (3)  Any compatiblity problems?

None (that I've seen).  I have had a 286i card in my AT&T 6300 for a couple of
years now.  I think my Norton SI rating is up around 17 or so (I also have a
V30 instead of my 8086i chip).

SOTA 386si is available for $380 through PC Connection in New Hampshire. This
is where I purchased mine.

homerun@portia.Stanford.EDU (Matt Watson) (03/20/90)

Sota had to recall all the memory/16i daughterboards for the 286i/386i
because of numerous bugs.  This was told to me last week by PC Connection,
where I got my 386i board last summer.  It uses a 386sx chip, which is how
Sota hopes to use the same expansion board for the 286i/386i.  I have mine
running on an IBM ps/2 mod. 25 and it flies...

hope this helps...

  - The accelerator card itself uses the mother board's 8-bit memory
    I don't know about the 286i, but the 386i uses a 16k cache to 
    speed throughput.   The 8-bit memory is a bit of a bottleneck,
    but the card will speed up many operations.  You can buy a 16-bit
    memory card that attaches to the accelerator card, though.  It
    can be populated with up to 4mB.  
> (2)  Does the 386 use a 386 or 386sx? Does it come with 32bit memory?
    386sx.   16-bit memory, of course
> (3)  Any compatiblity problems?
   Many machines require special adjustments ("fixes") to the board.
   For example, the off-the-shelf board and/or the memory card will
   not work with a Zenith, but with the addition of some soldered wires
   and the odd capacitor or resistor the card works fine.  Phone Sota
   first and ask if a "fix" is needed for your machine; distributors
   usually don't know about this.

   A few minor glitches.  Anyone interested in details, send me an

  along more details of my own experiences (see my previous posting).

Well, I've had the Memory/16i daughtercard backordered for nearly eight
months now.  Does anyone know if it *is* out, ever *was* out, or when it
*will* be out?  Performance with the cache is usually pretty good (I'm
running with no problems on an IBM PC-1), but I'd like some EMS.

I've only had two minor technical problems with it, and in both cases,
a quick call to SOTA had the problem fixed within twenty minutes.

Can the Sota cards be used in a PS/2 model 30
(NOT the 30 286) with 8086?

Yes.
