Introduction
1.1 Hardware Overview
The GTEKModel 2010 single board computer is intended to be the
best single board computer to use for control applications ever made.
The 2010 has 40 programmable I/O lines. Each I/O line may be
programmed foreitherinputor outputwithoutregardto itspositionon
the connector. Eight ofthose40are PORT1of the processor.The other
32 are on 2 Z80 PIO chips.
In addition to those 40 I/O lines, are lines to be used to expand the
functions of the 2010 board. AD0-AD7, ALE, RD, WR, PSEN, A8- A15,
ROM, CMM, VDD, P1.5, P1.6, P1.7, Vcc, Vdd, DTR and GROUND are
brought to a 34 pin expansion bus (see appendix A). This makes
expansiontomorememoryorboards,likeaD/AA/Dconverterormore
I/O, easily attached. With proper design, the board could just piggy
back on top of the 2010.
The 2010 has a built in 5volt regulated power supply. It needsto be
connected to a single ended power supply capable of at least 9 volts
at 500 milliamps to be adequately powered. If you attach expansion
boards to it, you must usean adequate power supply. The RS-232 uses
a MAX-232 chip to obtain the + — 12 volts for the RS-232 supply.
With the proper power supply, you can supply approximately an
other 250 to 500 milliamps to peripherals. You must provide for
adequatecooling ofthe regulator,however.Theregulator iscapable of
delivering up to 1amp provided proper heat sinking is provided.

1.3 Software Overview
Much of the software for the 2010 is strictly communications
software. That is, you could use other programs to communicate with
the 2010, but our software will recognize upload, download and other
commands and handle them accordingly.
Most of thecommands are handled by the2010directly, rather than
on your computer. This allows it to run in the same way on virtually any
computer or terminal.
The software used to handle communications is called B51.COM.
A program called PINSTALL is provided to install it for the Baud Rate
or COM port you are using. The software used to handle
upload/download from the BASIC option is called B51.COM. Use B51
to save/load your basic programs either in an ASCII format for imme-
diate use with an EEprom, or in a tokenized format so that you can
dedicate the controller with a BASIC program in an Eprom.
1.4 Software Specifications
Although the 2010 is capable of communicating at Baud Rates of
from 300 to 57,600 Baud, B51 communicates at 9600 Baud. Com-
mands areavailable to saveor load an ASCII BASIC program, and save
a tokenized BASIC program to execute from a burned Eprom.

1.5 Firmware Overview
Much of the versatility of the model 2010 board comes from being
able to refresh ram through an interrupt service routine every 2 mil-
liseconds.Thebuiltinmonitorfirmwaretakescareofthisinconjunction
with the PAL. You arenot awareof this going on except that you cannot
make exclusive use of the timer taking care of this function.
Much of thefirmwaremonitor istied into thePAL functionality. This
means that if you write code to go into the Eprom or EEprom, then you
must also includethemonitor code. Ifyoudon’t you may losefunction
of the ram refresh and of course all of the built- in commands and
RS-232 communications. When using the B51 program to save
tokenized basic to beput intoan Eprom,youshould usetheMKE.BAT
program to put the monitor and other things into the correct location
in the Eprom.
1.6 Firmware Specifications
The firmware included with the 8052AH BASIC chip takes care of
the Ram Refresh and new commands added to 8052AH BASIC. Refer
to the memory map. Locations 0-1FFFH in code memory are reserved
for 8052AH BASIC. 2000H Through 7FFFH is reserved for BASIC and
the firmware monitor. When using a 2864 or 2764 (8K memory device),
it is inserted at locations 2000H through 3FFFH. When using a 16K
device, it is inserted at 2000H through 5FFFH. When using a 32K
device, it is inserted at 2000H through 7FFFH. Note that you lose 8K to
the 8052AH BASIC monitor rom.

Getting Started
2.1 Unpacking
When unpacking the model 2010 board, be sure to watch for items
such as jumpers, disks, cables, and instructions and/or errata sheets
whileyouareunpacking.Many phonecallshavebeenmadeinthepast,
because in the haste of unpacking and getting to the main board,
material that was thought to be packing material was protecting a disk
or instruction manuals. These materials should be plainly marked as
"instructions"or "disk", but some people don’t take the time to read it
and discard it. If you think you are missing anything from your order,
please be sure to go back through the packing material to make sure
that it was not acci dentally discarded.
2.2 Installation
The 2010 board (depending on the options ordered) generally
comesset up to plug in and run. Yours should be set up with the Basic
monitor on a 2864. Jumpers will beset for this installationwith no other
option jumpers.
2.2.1 Quick Start
To begin communicating immediately with the board follow these
instructions:
1—Plug in RS–232 cable to computer and 2010 board. (or make
cable from instructions in appendix D).
2—Plug wall transformer into board.
3—Plug wall transformer into 120 Volt outlet.
4—Run B51 (B51 is an optional program) communications pro-
gram.
5—Issue commands.
Remember that if you don’t have theB51communicationsprogram
that you will have to set the communications parameters first on your
computer to communicate with the board. The 2010 is set up to be a

DCE device. This means that on an IBM PC or ATtype computer (that
has a DTE port) the cable will run straight through.
2.2.2 Normal Installation
After unpacking the 2010, set it up for your use. Normally, it will
already be installed to use with the 8052AH BASIC. However, you may
install the board in this manner:
1—If you didn’t get a cable from us, make an RS-232 cable like this:
a) The cable required is a straight through cable. Pin 2 on the
computer hooks to pin 2 on the 2010. Hook up pins 1, 2, 3, 4, 5, 6,
7, and 20. 8052AH BASIC does not require hardwarehandshaking,
so you could just use pins 2, 3 and 7 for a cable.
b) The computer end of the cable will require a female connector,
while the 2010 end requires a male connector.
2- Hook the RS–232 cable to the 2010 and the computer.
3- Check the jumpers for operation. A normal first time operation
willalready havethejumpersinthecorrect location,howevercheck
the jumpers as follows:
JB5
—1 is /EA of the processor pulled high by a 2K RP (for internal
program memory).
—2 is Ground (for external program memory access)
Default: leave thisjumper open for usewith 8052AHBASIC. Ground
it to use the 8052AH as an 8032.
JB6
—1 is Vcc. (used for 2764/27128 /pgm pin.)
—2 is pin 27 of the program memory socket (common).
—3 is A14 of the Address Bus
—4 is /WRfrom the processor
Default: 4–2for 2864. Hook 1–2for 2764,27128. Hook 4–2for 28256
to allow /WR to program EEprom. Hook 3–2 for 27256, 27512 to
allow A14 on pin 27 (A14).

Default: 4–2for2864.Hook 1–2for Vcc to Vpp of 2764,27128,27256.
Hook 4–2 for 28256 to allow A14 onto pin 1 (A14). Hook 3–2 for 27512
to allow A15 onto pin 1 (A15).

27512 32K Eprom 1–2 2–3 2–3 ML
27512 24K Eprom none 2–3 2–3 BASIC
JB5 controls external access of program code fetches. If it is
jumpered /EA is grounded,forcing theprocessor to fetch codeexter-
nally from the Eprom. If you have a 8751 or 87C51 you should leave
pin1and2ofJB5open(none)tofetchcodeinternallyfromtheEprom.
JB6 controls where pin 27 of the program memory socket (Eprom
or EEprom) connects. Pin 27 connects to pin 2 of the jumper block. If
pin 2 is jumpered to pin 1 (Vcc) then that pin is held at Vcc for a 2764.
To pin 3willconnect line A14 to pin 27for a27256. To pin 4will connect
/WR to pin 27 for for /WE for 8K EEproms, Xicor X2864A for example.
JB7controlswherepin1oftheprogrammemorysocket(Epromor
EEprom) connects. Pin 1 of the program memory socket connectsto
pin 2 of the jumper block. If pin 2 is jumpered to pin 1 (Vcc) then that
pin is held at Vcc for a 2764. To pin 3 will connect line A15 to pin 1 for
27512. To pin 4 will connect line A14 to pin 1 for a Xicor X28256 for
example.
