Notes The TS-1000 was the American version of the Sinclair ZX-81 which followed the successful Sinclair ZX-80. The popularity of these machines was driven by their low price. In an era of $1,000 computers a machine that came in at $100 to start was noticed.
Related Items in Collection Another TS-1000, books, etc.
Related Items Wanted Printer, additional RAM and software.


The TS-1000s in my collection are not yet tested.

Included in the collection are the machines, manuals, at least one RAM expansion (16K) and some software on cassette.

Thank you to Eric Lakin for the generous donation of a TS-1000 with docs, etc.

Today - NOW - people text on phones with little keyboards that are half the size of the Timex, and still everybody complains about the little Keyboard on the ZX-TS unit. The secret was to take 2 new pencils and hold them and polk with the erasers on the keys of the timex. U could key up the programming keywords almost as fast as you could say them. The TS1500 was the king of little computers that would run forever. I left it on in a basement with a programs loaded for over 5 years and it never crashed ! ALL was lost when the basement was flooded a year later back then. AND if anyone has the schematics for these - meaning TS1000, 1500, 2068 and QL - kindly drop an email.

My first computer was a TS-1000 for $50 at Radio Shack. Took it home with the two books and proceeded to key in every one of the programs in those books plus a few more (and then I had to figure out why some didn't work because of my shoddy typing skills. Sent money to Sinclair Corp. in England and got schematics. About 2 hours of cutting, drilling, and installing jumpers and I had 8K installed internally with the possibility of piggybacking another 8K chip or 3 or 4 later. Since I didn't have a printer, I handwrote the instructions in a notebook, photocopied them, and passed them out to some of my friends in and around Lexington, KY. Enter the TI 99/4A (QI), and I basically relegated the TS to the closet shelf from which a 'friend' stole it. Ahh, those were the days...

Looking for a TS100 complete in box. Contact me if you are willing to sell your TS1000. Oh, and a 16K RAM pack would be nice as well.

My first home computer, I wrote animation software , did machine code (wow fast) programing, even had a flight simulator. I even found a aftermarket clone in a shop in Toronto. Had a way better keypad, raised rubber keys, I wore out 2 keypads on mine I used it so much, eventually bought a aftermarket keyboard with real keys. My favorite thing I did with mine was a parallel output board, used it for a light control board with triacs, good times, was able to program light shows .

I just picked up a like new Timex Sinclair 1000 with original packaging/contents, 16K RAM Module (again like new with original packaging) and 8 tapes for FREE off of Craigslist. I am so happy. My dad and I learned how to program off of one of these back when they first came out!

Some positive attributes for the TS1000: 1. It was cheap. 2. It had a decent BASIC with graphics commands. 3. It had a damn good manual that one could learn how to program with (I did). 4. Did I mention how f*cking cheap it was?

This was my first computer. They had BASIC in ROM so we'd code programs in and save them to a cassette audio player. I remember it took ~5 minutes to save or load the simple programs. As often or not, the load would be bad and you'd have to start over.

I remember buying one of these at the Navy Exchange in Yokosuka Japan when I was in the mavy there back when they first came out. I absolutely hated the keyboard, and wound up ordering a supposed fix for it, I don't remember from where. It turned out to be a cheesy plastic plate that you glued onto your existing keyboard that had small posts that pressed the existing keys for you. Silly me, I thought I was getting a replacement keyboard. Despite all this, I had fun with the system and learned Basic programming in the process.

A friend had one of these, with no permanent storage so we had to key in programs from scratch! The thing would overheat after about a half hour so we'd sit a bowl of ice on it to get enough runtime to key in the program and use it. Fun times!

The reason I landed here is that I was looking for the TS1500 Schematic. Does anyone know where I can get a schematic of the TS1500 (Timex Sinclair 1500)? I've just repaired one, but one lead of coil L4 is broken loose and I don't know where to reattach it (I don't want to open my other TS-1500 just to look for the coil connection, but may have to if I can't find the schematic). The interesting thing about this machine is that several of the 4116's were bad, and the mask ROM was blank (contained all $FF's - I burned an eprom and replaced the mask ROM with that.) After replacing a couple of the 4116's and replacing the ROM the machine works great, but I don't want to leave the lead of L4 unconnected - a schematic would be great. The one from TS1000.us would be great, but it's not there anymore (http://www.ts1000.us/files/ts1500schematic.pdf) - I can't find it anywhere. Any help would be greatly appreciated. -Robert

My first computer was a TS1000, when people now complain that it was slow, and had a rotten excuse for a keyboard, I just have to shake my head, not because they're wrong, but because it was also amazingly affordable.

I bought my TS1000 with my measly allowance money, there's no way I could have saved up to buy an Apple ][ or even a TRS-80 or PET, but I was able to buy my own computer and learn to program, I loved my TS1000, and it still owns a small black wedge shaped place in my heart.

If I remember this correctly, part of the reason this computer was so inexpensive and slow is because the video interface was implemented in *software*, it could only run your program during the horizontal and vertical retrace!


(Submitted October 25, 2009 07:53:56 by Bill McCormack)

Yes, it was slow, but affordable. I was a COBOL programmer when this came out and I used one to teach my kids basic programming at home. My oldest son used it to create a menu for a local restaurant, funny, he now owns a restaurant and a computer. You never know.

This was my first computer. It drove me crazy with its slowness. But I used it anyway, because hey, it was a computer! In my own house!
