Deirdre (US) Monday 28th September 2020 My first computer bought w/Tandy credit card at 21$ interest, so I got the bare bones model. Used a black + white portable TV as a monitor. Not great when I was taking a BASIC programming class. Had to scroll up and down to see the line $s due to the curved left and right sides of the TV''s display. Loved DeskMate software!

SteveAngel (United States) Sunday 26th November 2017 I had a base Tandy 1000. It definitely didn''t have DOS or Deskmate in ROM. I used the basic system until I realized it was almost unusable without the upgrade to 640K. I also had the Tandy 300 baud modem which was an abomination that had no speaker and couldn''t detect busy signal. I later upgraded to a 10 meg hard drive after I figured out how Tandy had flipped the Hard Drive and Video IRQ''s on the motherboard so you needed a specially modified Western Digital controller board to make it work. Despite all of that I loved the thing!

Guy (Hawai''i) Tuesday 2nd August 2016 I had both the Tandy 1000 (purchased in 1986) and the Tandy 1000 TL. I was very satisfied with both. I was a previous owner of the TRS-80 (my introduction to home computers and programming). The things which that drew me to the Tandy 1000-series were the price (several hundred dollars cheaper than the IBM counterpart), ease of upgrade (I always installed my own parts) and the 16-color monitor and 3-voice sound card (available in the PC Jr, but no one wanted a computer named Junior!)

Skel (Canada) Friday 30th January 2015 I HAD a Tandy-1000. It was in perfect working condition but sadly, when I had to move from a house to an apartment (downsizing) two years ago, it simply could not fit. I had a choice $ keep the Commodore 64 (the computer I had as a kid) or the T1000 (one that was gifted to me 10 years ago from family friends). The case of the computer was damaged in a house fire years before but it otherwise worked perfectly. In the end, it was scrapped for parts. :( I kept those parts and used them when I was teaching at university as part of a class project to construct a computer. :) In a way... it lives on. I enjoyed writing this article years ago and still love to read it. :)

Logan (Arkansas) Monday 17th October 2011 I have a tandy 1000 TL/2. It has 640kb of RAM, a 3.5 inch floppy drive for 760k disks, CGA monitor, and Deskmate 3. Deskmate comes with Hangman, a word processor, a program to create and record music, a worksheet program, a painting program, a caculator, some schedule keeping things, PC-Link, address keeping programs, a telephone answering program, and MS-dos 3.3. Deskmate and DOS are built into the ROM so it starts up very fast (3-6 seconds!). It has 4 8-bit ISA slots (I think), you can add an IDE hard drive, and a CD-ROM drive can be added. Somehow the monitor works even though one of the connection pins on the cable is missing. anyway its an excellent machine.

Pat (Canada) Wednesday 18th May 2011 Wow, what a trip down memory lane... I bought the the original Tandy 1000 (4.77mhz, 128k ram, 2 5¼ disk drives, CGA monitor) for $1600can the year it came out (I was a teenager). I later bought an expansion board to bring the ram up to 640k, which also set be back some serious dough back then! :) It was indeed a beast in its days. It''s unreal how many lawns I mowed and kids I babysat to pay for that toy!

Steve A (USA) Monday 20th September 2010 The Tandy 1000 was my gaming machine, side-by-side with my Colecovision. While the Colecovision has long since been dead, my Tandy 1000 still runs when I hook it up. I still have 20+ games, all in 16 color glory. It''s nice knowing it still chugs along, because it was a great introduction into PC gaming :)

Robert H (USA) Tuesday 31st August 2010 Much as I hate to argue, but the Tandy 1000 HX was not the first. The original was the Tandey 1000 (no letters after) I always wondered what dad $ped on mine was, but I spent many summers as a kid cutting grass just to pay him for it. It was my first true DOS pc. Prior to that I used a CPM board and a WHYSINC terminal. My T-1000 was a beast for the time I had the memory maxed, a 3.5 inch 720k floppy, and a 20 meg MFM HD card. (it was a drive mounted on a card that was latter replaced with two 70meg 5.25 full hight HD in a AT case. I went to the local computer junk store and had the ribbion cables custom made (about 3 feet a peiece. the data cable and the two control cables) I used that system till it finally died and I moved on the the 386/16mhz around 1988. It was the Best first real computer I ever hadm and even though I have sever Laptops and desktops with things that I never would have thought of then I still miss that old Tandy PC

Seth (Earth) Thursday 8th February 2007 As a child, we had the Tandy 1000 HD in our house, which was the original Tandy 1000, but with a 10MB hard drive in the 2nd bay instead of a floppy. I can't imagine what my dad dropped to buy that machine at the time (circa 1985). Let me tell you, this thing was a rock! I think it never actually died, we just ended up replacing it with a 386 at some point. I owe my DOS skills and lifelong fascination with computers to that system.

The Tandy 1000 was a line of IBM PC compatible computers made during the 1980’s by the American Tandy Corporation for sale in their chain of Radio Shack electronics stores in Canada and the USA. The Tandy 1000 would be the successor to their influential TRS-80 line of computers, the Tandy 1000 would eventually replace the COCO line of 8 bit computers as well when Tandy decided to prematurely end that project in favor of the Tandy PC line of computers.

Targeted toward the home user with a modest budget, it copyied the IBM PCjr's 16-color graphics (PCjr's graphics were an extension of CGA video) and anhanced 3-voice sound, but didn't use the PCjr cartridge ports, instead the Tandy version had built-in game ports compatible with those on the TRS-80 Color Computer (COCO), as well as a port for a "light wand/pen". Most Tandy 1000 models also featured “line-level” sound and composite video RCA outputs built onto the motherboard so that a standard television could be used as a monitor, albeit with much poorer video quality. Unlike most PC clones, early Tandy 1000 computers had MS-DOS built into ROM allowing the OS to boot in a few seconds. Tandy also bundled onto floppy diskette “DeskMate”, a suite of consumer-oriented applications, with several models. Besides a composite output to TV, as mentioned earlier, Tandy 1000’s also housed a built in CGA video adaptor equal to PC standards built onto the motherboard and since the Tandy 1000 outlasted the PCjr by many years these graphics and sound standards became known as "Tandy-compatible" or "TGA," and many software packages of the era listed their adherence to Tandy standards on the package. One odd feature of the Tandy-1000, however, was a non standard edge card printer connector built onto the motherboard and protruding through the rear; an adaptor would be needed to work a standard IBM style printer.

In 1984, when the “T-1000” was in its prime, you may have paid up to $2499.00 (Canadian) for a full featured system with matching monitor.

The original line was equipped with the Intel-8088 CPU at 4.77Mhz, which was later extended to faster clock speeds up to 7.16Mhz, as well as the upgrade to 8086 and 80286 processors at 10Mhz (in the TL & TX configurations). Common models of the machine included the Tandy 1000, EX, HX, SX, TX, SL, SL/2, RL, and TL, TL/2, TL/3.

The “T-1000” was a workhorse in the IBM PC world, large numbers of units are still in active service today as it’s construction was quite robust. The T-1000 was Tandy’s last attempt in the home computer market. In the early 1990’s Tandy Corporation sold its computer manufacturing business to “AST Computers”. When that occurred, instead of selling Tandy computers, Radio Shack stores began selling computers made by other manufacturers, such as “Compaq”.

The original Tandy 1000 was similar in size to the IBM PC except it had a plastic case to reduce weight. The original Tandy 1000 featured a proprietary serial keyboard port along with 2 similar joystick ports on the FRONT of the case (a feature that would become standard in later models). The rear featured a PC standard monitor connector (compatible with CGA/EGA), a composite (TV) video-out connector, a single RCA-style monophonic line-level audio connector, a port for a light pen, and the unusual edge-card connector used to attach a parallel printer.

The original Tandy 1000 came standard with one 5.25 disk drive, with an additional bay usable for the installation of a second 5.25 disk drive (available as a kit from Radio Shack). 128k of memory was standard, with the computer accepting up to 640k of total memory with the addition of expansion cards. MS-DOS 2.11 and DeskMate 1.0 were included with the system.

The Tandy 1000 offered 256 characters: 96 standard ASCII characters, 48 block graphics characters, 64 foreign language/Greek characters, 16 special graphics characters, 32 word processing/scientific-notation characters.
