Sean, Fred, and Glen ?
Sorry, late to this ISA card thread.
I worked in Tech Support for an Apple/IBM/HP/Novell retail computer dealer,
during summers in early 1980s, when in Graduate school.
So I saw the ?wide selection? of add-in cards for IBM PC/XT and compatibles.
==
This is a ?Taiwanese generic 6-Pak? Add-In (8-bit ISA) expansion card.
RAM 384 kB; Serial port, Parallel port, Game port, AND Real Time Clock !
Glen is CORRECT, the National Semiconductor MM58167 is the RTC IC.
Texas Instruments bought out National in 2011, data-sheet still available.
The ?solder-in? B1 battery has been cutout (open space below/left of MM58167).
Replacement battery (likely ~ 3 to 3.6 Volt) can be acquired from Digi-Key.
Take measurements and closeup photo of ?B1? Area, to CONFIRM Model and Size.
?
My Quick Guess ?
Tadiran TL series 1/2 AA with Axial pins, 3.6V High Capacity Cylindrical battery

Tadiran TL-5902/P .... $6.65

Isn't the 24-pin DIP part number MM58167 ,shown in the images referenced above,

I got this (currently exploded) mystery RAM, RTC, and I/O board out of
a dead Sanyo luggable the other night, and once I replace the burned
up tantalums I'd like to put it in my 5150 so I can get a full 640k of
RAM.
Question is, does anyone know what this board is? It's a completely
anonymous board with not even an FCC ID to go off of. I'm assuming the
RAM is at least strapped right; all the banks are full which should be
384k, and the Sanyo was a 256k machine = 640k.
Here's a couple pictures; one's an actual picture of the card and the
other is a simplified TULARC/TH99-esque vector of what's on the board.

It resembles, although doesn't match, the AST Six-Pack.
But the AST Six-pack had a clock circuit.

BTW -
IF you look at advertisements in the 1985-86 PC magazines, this was typical:
PC Network (Mail-Order/Telephone reseller).
PC NETWORK SIX-PACK? CLONE with 0K $89.00*
Full Six-Pack? Features ?Game Port Standard. Direct Import from Taiwan at a Fabulous
Price!
==
The ?unknown? is whether the AST software utilities, ASTCLOCK and SETCLOCK
will work with National/TI clock chip in your Taiwanese multi-function card.
Some worked with it, others did NOT.
==
Jumpers behind the DB-25M serial port will be for
Serial Port configuration (IRQ, memory address).
Parallel Port will have jumpers for LPT1 or LPT2 (Monographic card installed, add 1).
==
The 6-switch (DIP) will be ?binary? for RAM installed & starting RAM address (256k?).

Exactly. The generic "QC OK" oval sticker is the tipoff that this is
generic Taiwanese. I've got other generic "Computer Faire" cards with
the same sticker. I think that Quadram may have used the same NS RTC
chip on their early Quadboards, but I'd have to go digging through my
hellbox to make certain.
Nothing wrong with the generic ERSO-inspired designs, either.
FWIW,

Is "QC OK" the brand name? :-)
They made a lot of stuff.
Some of their premium stuff was designed by Pat Pending.

Clearly we need a QC OK stickers reproduced onto a T Shirt for the next
time we can get together...

Well, thanks for all the help guys - Finally narrowed it down to a
JE1078 on Stason:
https://stason.org/TULARC/pc/io-cards/I-L/JAMECO-ELECTRONIC-COMPONENTS-Mult…
I can believe this thing was made in Taiwan - I had to repair probably
1/4 of all the joints on the card because they all had gone dry or had
holes in the joints. Have you ever seen solder bubble like boiling
water? That's how bad the original solder on this card was. It also
absolutely stank the whole way through...
