TANDY 1000 RL/HD (25-1450/51) Settings Faxback Doc. # 1302
Note: Refer to Faxback Doc. # 1375 for locations on Main Logic Board and
Satellite Board.
Video Sync Interrupt Jumper: E12-E13 Jumped for IRQ 5 set for Video Sync
Removed for IRQ 5 on bus (default)
Microphone/Line Audio Jumper:
This jumper is to determine what is plugged into the microphone connector
on the back of the CPU. The jumper will fit over two of the three pins, the
two pins will correspond to the silk-screened words, Microphone Input and
Line Audio Input, on the satellite board.
The two choices are as follows:
Microphone Input: For a microphone only.
Line Audio Input: For things such as stereos, guitars, keyboards, and
other audio equipment that has line-level output into
the connector.

The Tandy 1000 RL Computer (250-1450 / 250-1451) is an 8 Bit, XT Class
computer that utilizes an 8086 processor. The machine was originally
designed to compete with the other 8 Bit, XT class computers that were on
the market at that time, most of which employed slower 8088, or NEC-V20
processors.
The 1000 RL was sold in two configurations, one being the 1000 RL
(250-1450) which did not have a hard drive, and which had 512 K of RAM.
The other was the 1000 RLHD (250-1451) which did have a hard drive and
768 K of RAM. The 1000 RL could also be upgraded by adding a hard drive
and memory up to 768 K.
If you are needing a replacement for the original software or the original
owners manuals that came with this computer, you can also order them from
the Tandy RSU department at 800-433-2024.
The original software consists of the following:
MS-DOS/GW-BASIC VERSION 3.30.22 - 1 DISK
DESKMATE / HOME ORGANIZER - 5 DISKS
These would be ordered using the catalog number of the 1000 RL (250-1450
/ 250-1451).
Unfortunately, you will find that at this time it is becoming increasing
difficult to find upgrades, peripherals, and software that meet the
limitations of your computer.
When the 1000 RL was originally sold, the majority of the machines on the
market that were affordable by the average consumer were XT Class computers.
The AT Class computers were mainly sold as business class machines and
generally cost at least twice as much as the 1000 RL did. Even those AT
Class computers, mostly 16 Bit 80286 and 80386 based machines, would be
considered to be slow and out of date by now. In just the short amount of
time between then and now, 80486 and Pentium based computers have become
the industry standard, due both to advances in technology and to the demands
of the customer. More than likely, these computers will also be considered
obsolete in just a short time.
When attempting to locate upgrades or peripherals for your machine, we
recommend that you concentrate on smaller mail order companies, rather
that chain computer stores. Most chain computer stores will only carry
the most recent peripherals. A smaller mail order company will have a much
lower overhead, and will be able to carry older or more specialized pro-
ducts. Listed below are the names, addresses and phone numbers of two such
companies:
PC ENTERPRISES DCS INDUSTRIES
2400 BELMAR BOULEVARD, BLDG B16 5265 HEBBARDSVILLE ROAD
WALL NJ 07719 ATHENS OH 45701
800-922-7257 800-537-3539
908-280-0025 614-592-4239
Both of these companies offer peripherals such as hard drives, modems, and
upgrade adapters for XT class computers such as the 1000 RL, and both are
fairly familiar with the Tandy 1000 line of computers.
Please note that the above mentioned companies are not affiliated with
Tandy Corporation / Radio Shack in any way. Therefore, we cannot guarantee
nor support the use of their products.
Unfortunately, you will find that even with these upgrades, it will be
increasingly difficult to find software that meet the basic limitations of
your computer. Many of the current programs on the market, will not work
on the Tandy 1000 RL or any XT Class, 8 Bit computer. Because of this, we
feel that we must advise you that if you wish to use most of the software
on the market today, you would probably be better off saving up for a new
computer, rather than sinking a large amount of money into your older
computer. However, if this is not specifically a requirement, and you are
simply interested in simple word processing and filing, the 1000 RL should
be able to provide useful, if somewhat limited service.
The Tandy 1000 RLX Computer (250-1452/1453/1452B/1453B) is
an 8 Bit, XT Class computer that utilizes an 80286
processor, that was originally introduced to the Tandy
product line in 1992. The machine was originally designed
to compete with the other 8 Bit, XT class computers that
were on the market at that time, most of which employed
slower 8088, 8086, or NEC-V20 processors.
If you are needing to replace the original disks or manuals
that came with the 1000 RLX, you can order them through
Tandy Software Replacement at 800-433-2024.
You would order the disks using the catalog number of the
computer itself, which can be found on the back of the
computer. It will be one of the following numbers:
CATALOG # DESCRIPTION
250-1452 1000 RLX - MS-DOS 3.30 - DESKMATE 3.04
250-1453 1000 RLX - MS-DOS 3.30 - DESKMATE 3.04
250-1452B 1000 RLX - MS-DOS 5.00 - DESKMATE 3.04
250-1453B 1000 RLX - MS-DOS 5.00 - DESKMATE 3.04
The owners manual for this computer can also be ordered from
Tandy Software Replacement. Insure that when you order the
software and the manual that you give the correct catalog
number for your computer so that you get the correct
software and manual for your computer.
If you wish to obtain other books on using PC Compatibles,
and MS-DOS, we suggest you look in the computer section of
your local library, or in a used book store. We suggest
this because you will be using an older version of MS-DOS on
that computer. The version of MS-DOS that came with that
machine is either MS-DOS Version 3.30 (250-1352/1353) or MS-
DOS Version 5.0 (250-1352B/1353B). The version of MS-DOS
that is currently on the market is version 6.22, which,
while it will run on the Tandy 1000 RLX, will not give the
user any advantages. Most of the books that are currently
on the market for MS-DOS will be for newer MS-DOS versions,
and the information will not be valid for either MS-DOS 3.30
or MS-DOS 5.0.
In addition, the 1000 RLX utilizes an 8 Bit Bus. To run
many of today's software packages, including MicroSoft
Windows, your computer must have at least a 16 Bit Bus.
Just as there is no way to turn a 4 cylinder engine into an
8 cylinder engine, there is no way to make an 8 Bit computer
into a 16 or 32 Bit computer, regardless of the make and
model.
When shopping for software, you must keep this limitation in
mind. On almost any software package, there will be a list
of the minimum requirements for that program to run. If the
computer does not meet any one of these requirements, the
program will not work.
You may also wish to contact one of the mail order companies
listed below when looking for software. Both of these
companies specialize in software, peripherals and upgrades
for older XT class computers, such as the 1000 RLX.
