The recommended switch settings for the OmniBridge controller are

as follows:

1-1 DOWN 2-1 DOWN

1-2 DOWN 2-2 DOWN

1-3 DOWN 2-3 UP

1-4 DOWN 2-4 UP

These settings select NO ADDRESS for the OmniBridge BIOS and

allow it to coexist with the internal FDC of the computer in which it

is being installed.

This way you do not need to disable the internal

FDC or connect any cables from the OmniBridge to internal floppy

drives. This was found to be a universal setting for all of the

computers listed above as compatible with the OmniBridge controller.

PSB No: S-0098

Page: 2 of 8

Q. What kind of printer can I use with the APEX 200?

A. The APEX 200 includes an IBM PC - compatible parallel interface which is

used to connect any printer or plotter with a standard parallel interface.

An IBM PC- compatible parallel printer cable (not included) is required to

connect a printer to the computer.

Epson currently offers outstanding printers in the ActionPrinter line. The

T- series printers are 9 - pin printers with near letter quality print.

The T -

1000 is an 80 column printer and the T750 is a 136 column printer. The

L- series printers are 24 - pin printers with superb letter quality print.

The

L1000 is an 80 column printer and the L750 is a 136 column printer.

Q. What type of hard disk drive does Epson supply with the APEX 200\20

and APEX 200\40 and what is the average disk access time?

A. The Apex 200\20 uses a 5.25”, half - height, 20 MB, Seagate ST- 225,

MFM hard disk with an average disk access time of 65ms.

The Apex 200\40 uses a 5.25”, half - height, 40 MB, CDC 94205 - 51 MFM,

hard disk with an average disk access time of 28ms.

Q. Can a higher capacity hard disk drive be installed?

A. Yes, if you install a new hard disk drive, refer to the Drive Type Table in

Appendix F of the Users Guide to match the drive type to the number of

heads and cylinders.

If you cannot match the drive parameters with the

drive type table you can use the next lower cylinder number with the same

head number, however, this will not give you the full drive capacity. An

alternative method, under MS - DOS, is to use a disk manager software

such as SpeedStor or Disk Manager (available from software dealers). This

software will allow you to format the full disk capacity for use.

Q. Is the Plus Development Hardcard 20 or Hardcard 40 compatible with the

Apex 200?

A. Yes, the Hardcard 20 or Hardcard 40 must be configured in SETUP as

not being installed by setting the drive type as none.

PSB No: S-0098

Q. What kind of floppy disk drive does the APEX 200 have and what kind of

floppy diskettes should I use?

A. The APEX 200 - series computers use a half - height, 5 1/4”, 1.2MB floppy

disk drive.

You can use both double - sided, double - density, soft - sector,

48 TPI, floppy diskettes for 360KB capacity and double- sided,

high - density, soft - sector, 96 TPI floppy diskettes for 1.2MB capacity.

The

360KB diskette boxes are usually marked DSDD or 2S - 2D, Soft - Sector,

48TPI and the 1.2MB diskette boxes are marked DSHD or 2S- HD, 96TPI.

New blank diskettes must be formatted using the MS - DOS utilities provided

before being used.

You must use the command “FORMAT /4” to format

the 360KB double density diskettes.

Q. Is it possible to disable the APEX 200 floppy disk controller?

A. Yes, by changing jumper 2 on the SPF2 board from the A to the B

position.

Q. Can I use other types of floppy disk drives with the APEX 200?

A. 5.25”, 360KB, half - height floppy disk drives are compatible with the APEX

200 personal computer.

The Epson 3.5”, half - height, 720KB floppy drive

(Epson Model code A112A- AA) and the Epson 3.5”, half height, 1.44MB

floppy disk drive (Epson Model code A811151) have been tested with the

APEX 200 computer and are compatible (available from Epson Computer

Products dealers).

These Epson drives come mounted on a 5.25” frame

with a matching front bezel.

Q. How do you disable the parallel port on the APEX 200?

A. To disable the parallel port, jumpers J3 and J4 on the SPF2 board must

be set to position BC. To enable the parallel port, set the jumpers to AC.

PSB No: S-0098

Q. Can I install a Math- Coprocessor chip and what type do I need?

A. A Math- Coprocessor chip is an option which speeds up the floating point

math functions used in many spreadsheet and math - intensive software

applications. It can be purchased at electronic parts retailers and computer

stores (Epson America Inc. does not supply them). An Intel (8MHZ)

80287-8 Math- Coprocessor chip, is recommended for use with the APEX

200 computer.

The Math-Coprocessor chip is installed in the socket

provided at I.C. location 5C on the APEX 200 system board. The system

must be configured for the Math- Coprocessor option in SETUP.

Q. Where can I get application software for the APEX 200 computer?

A. You can use virtually all software programs written for the IBM PC/AT

computers.

Make sure the system requirements on the software package

match your computer configuration and video adapter type. Software is

available through Epson Accessories, Inc. at 1 - 800 - 873- 7766, or at your

local software store.

Q. Is the APEX 200 compatible with MS-OS/2?

A. Since OS/2 is much more hardware - specific than MS - DOS, the Epson

version of MS - OS/2 is required (available from Epson dealers).

A minimum of 2MB of RAM memory is required to run MS-OS/2.

Q. Will IBM compiled BASIC programs run on the APEX 200?

Most BASIC programs written for the IBM PC- XT will run on the APEX

200. Some IBM and Tandy BASIC programs will not run. This is because

they require IBM BASICA which is resident in copyrighted ROMs.

All

compatibles use a version of GW - BASIC which is loaded from diskette.

Due to differences in the BASIC, some programs will not operate correctly.

Q. Can I use the APEX Monochrome Monitor (Model # AP1040) with other

IBM PC - compatible computers?

A. The Apex 12” Monochrome monitor (Model AP - 1040) uses a TTL video

signal which is IBM PC - compatible and can be used with other computers

that have a monochrome TTL video board. It should not be confused,

however, with the earlier Apex composite video monochrome monitor (Model

# AP - 1010A) which is not compatible with the APEX 200 video board.

PSB No: S- 0098

Page: 5 of 8

Q. Can I use the Apex color monitor with other IBM PC- compatible

computers and what are the specifications?

A. The Apex 13” color monitor is an IBM PC-compatible, 16 color, RGB, dual

function monitor which can be set up for either color or green screen

mode with a switch on the rear panel. It has a 640 x 200 (black and

white) or 320 x 200 (4 color) graphics dot resolution. It can display 16

colors in 80 column x 25 row text mode. The dot pitch is .52mm.

Q. What other monitors are compatible with the APEX 200 and is it possible

to use a television set?

A. Most IBM PC-compatible RGB color or TTL monochrome monitors will

work with the video board provided with the APEX 200 computer.

Composite monitors are not supported. IBM PC- compatible EGA and

VGA monitors can also be used if the existing video board is replaced with

an EGA or VGA video board (available from computer dealers). The system

must be configured for EGA or VGA by selecting “Special Options” under

Video in the SETUP program.

A standard television set cannot be used with the APEX 200, although

there are some new TV sets being manufactured which can also be used

as computer monitors with the proper interface card. Check with a

computer dealer for more information.

Q. How many option cards can be installed in the APEX 200?

A. The APEX 200 has six l/O expansion slots (3 8 - bit and 3 16 - bit). The

video adapter board and the SPF2 board occupy two 8 - bit slots and

the hard. disk controller takes up a 16 - bit slot in the APEX 200.

The

I/O expansion slots can be used for a wide variety of IBM PC (8 - bit) or

AT (16 - bit) compatible option cards.

Q. What kind of mouse works with the APEX 200?

A. There are many IBM PC- compatible mice that will work with the APEX

200. Most manufacturers make two different types. A bus mouse comes

with its own interface board and takes up an I/O expansion slot in the

computer. Ensure the IRQ jumpers on the bus mouse board are set up for

IBM/AT compatibility. A serial mouse plugs directly into the serial port and

doesn’t use any option slots.

Microsoft, Logitech, Genius, and Mouse

Systems are popular models that can be used.

PSB No: S- 0098

Q. What kind of option cards are available for the APEX 200 computer and

where can I buy them?

A. Most IBM PC/XT or AT- compatible option boards should work in the

APEX 200 computer.

Some products are “speed sensitive” and are not

designed to work at the higher clock speeds (above 8MHz). You should

visit a computer retail store to see a wide range of products. Since there

are many different manufacturers it is impossible for Epson to test all option

boards available to insure compatibility. We recommend that you purchase

boards from a dealer who will exchange the board if for some reason it

is not compatible.

Q. What kind of joystick can I use with the APEX 200 and where do you

connect it?

A. There are many IBM PC-compatible joysticks available and some have

different types of connectors. The joystick connector must match the

connector type on the board it is being used with. An IBM PC-

compatible joystick with a 15 - pin IBM compatible game port connector

must be used with the Epson APEX 200. We recommend using the Kraft

Premium or Kraft KC3 joystick, as we have tested them with the APEX 200.

You do not need to purchase a game card as it is included with the APEX

200 video adapter card.

Q. HOW do you connect two joysticks when there is only one joystick

connector?

A. A joystick adapter cable with 3 connectors is available from computer

dealers which allows you to connect two joysticks into the single port.

Q. What type of modem can be used with the APEX 200?

A. IBM PC/XT- compatible internal modems can be used, as well as, external

modems which connect to the serial interface port.

Epson manufactures both types of modems, the Epson Link 1200 external

1200 baud modem (Epson Part No. C202A- A) and the Epson Link

1200 - PC internal modem (Epson Part No. C203A- A), which can be

purchased from Epson Accessories, Inc. at 1 - 800 - 873 - 7766.

PSB No: S-0098

Q. Will the APEX 200 work in foreign countries?

A. The APEX 200 computer can be used in both the United States and

internationally simply by selecting the appropriate input voltage on the

voltage selection switch located on the rear of the unit. The APEX 200 will

operate on either 115VAC or 230VAC at 50/60 Hz power.

Most monitors and printers are not designed to operate on dual voltages

and will be damaged if plugged into the wrong AC voltage. This applies to

the Apex monitors and printers as well. You should use a heavy duty step

down transformer to convert 230VAC to 115VAC for these types of

products.

Q. What streamer tape drives can be used for high speed backup?

A. The APEX 200 has been tested with the following file backup units:

Backup Diskit -60MB, Model TEX- 60 (Idea Associates)

Everex Stream

- 20MB, Model 4.02 (Everex Systems, Inc.)

Mountain Series 4000 Filesafe (Mountain Computer, Inc.)

Tecmar QT - 60e (Tecmar Inc.)

Tallgrass TG - 4060 + (Tallgrass Technologies Corp.)

Q. Are there any extension cables available for the APEX 200 enhanced

keyboard?

A. Epson does not provide extension cables due to FCC restrictions. Third

patty extension cables will work although they will not have a 90 degree

angle connector.

Q. What are the CPU wait states for the APEX 200?

A. The default wait state for the APEX 200 I/O bus is 1, adjustable to 4, 3,

or 2 by setting jumpers J2 and J3 on the ANDRO board according to the

User’s Guide. The system memory, (RAM and ROM) defaults to one wait

state adjustable to two by setting jumper J1 to B on the ANDRO board.
