Hypertrol Inc HyperBOARD V1.10

A hint from MacWorld, August 1989:

HyperBoard 

Stand-alone data acquisition 
and process control board de- 
signed to extend functionality 
of HyperCard. Plugs in to the 
serial port, includes 32K RAM, 
and has on-board BASIC inter- 
preter. $139.95. HyperTrol, 
303/938-1662. 

Can you dump the ROM of a P8052AH?

Doesn' t look like they're going to accept my $50 offer, and I'm not going to pay more than that for it with no software. I've attached photos from the listing, for anybody looking for this board in the future.

It's got the BASIC with the P8052AH-BASIC, 32K RAM, an RS-232 Transmitter/Receiver, and everything else is 7400 series. The barrel jack is down by the voltage regulator, so I'd imagine that's for power. RJ-11 is common for RS-232, albeit not on the Mac, but that's probably the serial port. The board is supposed to be for data acquisition and process control, but there's no I/O left besides the slots, so I would speculate they made various input cards to fit your application.

That's not necessary. These 8052AH-BASIC chips are well documented.

Well, there is the 16 pin socket marked "Socket" and the header connector marked "K1" so those could be for I/O.  I wonder if the slots use the Apple II pinout?  They're the right number of pins...

Found a guy who had one:

I've looked into this recently, and what I did was buy a very inexpensive
board from HyperTROL (in Boulder CO) which hooks up via the serial port.
The board has an 8 bit microcontroller (8052 I think) which you program in
basic via the serial port.  The board will run standalone and is easy to
interface with via Hypercard (calls to the serial port).  Right now mine is
being used as a fancy timer for a hydroponics setup.  The board is only $100.
Other cards are available for general D->A or A->D conversion.  They are a
bit more expensive and I'll probably build my own.  If you're willing to muck
around with hardware a bit but don't want to have to design everything, this
is probably a good way to go.

So there were A/D converters available for the sltos, but if the boards works standalone, you must be right about K1 or Socket.

No, it's not possible to built a Apple-II-Slot with these chips. The pinout must be different.

Some years ago I got a "standard" 8052 implementation of the late 1980s. In West-Germany sometimes called "EMUF":

There are 2 unpopulated sockets. You can develop some BASIC-Software with the BASIC interpreter (8kB or 32kB RAM), burn the program into an EPROM in one socket and put this EPROM into the other socket to run a small embedded system without need of interaction. There is a lot of I/O: GPIOs, AD and DA converter, two relais and a RTC.

The serial port is for the BASIC terminal, means you type in BASIC-Commands, you can start and stop the code similiar to other BASIC machines like Apple II, PET, C64.
