I bought one of these from a local store. I also got the 16k memory pack by Timex Sinclair too. This time I used velcro to make the connection more stable and this worked pretty well. The computer came bundled with software (whereas the ZX 81 did not) on cassette for Personal Finance, 2k games, 16k games, and Flight Simulator. I played flight simulator for hours on end. I also wrote some programs for it including a cassette file based inventory program in which you read the whole file in from cassette into arrays. Then you could manipulate the files as needed and when you were all done, you could write the file back to cassette. I also wrote an invoicing program but could never really test it because I never got a printer for this computer. - author: Clay Bowen (USA) date: Thursday 18th April 2013 text: I remember this being given away in boxes of Cheerios, like a "prize" - author: Jim (Canada) date: Wednesday 26th December 2012 text: |- I had a Timex Sinclair 1000 with the 16K mem expansion and thermal printer.\ This thing was a throwback to the dark ages of time sharing when you used a teletype for input and then waited around for something to happen.

I realy wanted the TS 2068 when i seen it.\ I had an old tape deck as well and a 16K back pack.\ You know what''s kinda funny?\ As i type this, the laptop is not much bigger. HA! - author: Paul S. (Cincinnati, Ohio U.S.A.) date: Wednesday 29th November 2006 text: Wow, seeing this brings back a flood of childhood memories; this was the first "real" computer that I had owned; I remember lusting over it, and the additional memory pack, for what seemed like a an eternity until my parents surprised me with it on Christmas morning. This was my first computer love and I spent many hours typing- keying in rather- those many lines of BASIC programs just to have the satisfaction of being able to see some line go across the black and white t.v. "monitor" (an old extra b/w tv my parents also gave me) or to play what could barely be considered a game now. Then, if all the stars alligned properly, I was able to save the program to a cassette tape (an old tape recorded- that can probably no longer be found in a store) and would be elated if I was then able to re-load the program from the tape (which, I seemed to have a very low success rate- but hey, I was only about 11 years old then). As I recall, I was able to make it produce some sort of sound, a low pitch and a higher pitch, even though the specs seem to indicate that there was no sound. After a couple of years, my parents moved me on to the Radio Shack TRS-80 Color Computer 2. I wish that I still had both of these computers but had decided to hand them down to younger cousins to play with after Windows came out, those kids can now sling code in circles around me and are making triple my income; I wish I had never of gotten lazy with lazy operater systems and pursued programming. When I have a child, I am going to locate and buy one of these old systems so that he or she will "cut their teeth" properly; kinda like when Dad insisted that I learn to drive a stick shift car before being allowed to drive an automatic transmission car. If you have one of these old systems, please keep it nice because I might offer a tidy sum when the time comes. - author: Craig Brophy (USA) date: Monday 14th November 2005 text: This was the first computer I ever owned. I first learnt how to program on this one using code I found in Mad Magazine. I had a tape drive with it. It used regular cassette tapes. I had a flight simulator the used both side of the tape. It took 45 minutes to load up the game. I also had a 16k Ram pack (Yup, 16K!). A big black box that plugged into the back. The ram pack cost as much as the computer. On a side note, I had to return the thing two times because of the poorly designed keypad. It would just stop working. - author: Bruce Roeser (Lake Mary, FL) date: Monday 7th July 2003 text: |- Oh man ... I remember this little guy. I had one of these back in '82. The computer allowed you to load BASIC programs off cassette. A friend of mine in California and I wanted to be able to work on software together but loading two halves of the program from cassette wasn't supported. SO ... I got a ZX80 manual and learned how to write assembly code for it. (To that point I had only written in BASIC or FORTRAN). Using the manual, I HAND assembled (in Octal if memory serves) a loader that would enable the two of us to work on our respective halves of the program. The loader would enable me to load the first half of the program into memory then it would move "MEMTOP" below the loaded portion so the 2nd half could load - then the loader would "splice" the two halves of the program together. Worked the first time I loaded it. This little machine was one of a couple of machines that really got me into software development. - author: tf (Ionia, MI) date: Monday 9th June 2003 text: I actually remember learning to type on one of these little buggers, rofl... it SUCKED!!! - author: Kevin (Dallas) date: Sunday 28th April 2002 text: The Sinclair was so simple that it begged to be modified. SYNC magazine offered a monly forum for enthusiests share programs and hacks. If you had patience and small fingers you never needed to buy software. Just type whatever you want from redily available source code. There were dozens of companies who manufatured various add-ons for the Sinclair. You coul get a real keyboard, up to 128K of memory, a sound modual and long life baterie to take it on the road. There was also a 40 coloum thermal printer and a modem. Because the sinclar had a simple instruction set and consumed only 9 volts many of these handy little black wedges ended up being uncased and stared new carears as the brains of various home robotic projects. The direct descent of the machines is still alive and well today in the for of the Rabit Technologies prototype / experimentors board which is powered by a Zilog Z180. The Z180 is an 18 MHz update for the classic Z80 1MHz chip and uses virtually the same instruction set. At one time Sinclars were used as door stops at Commodore headquarters. Comodore offered a short lized promotion where by they would give a $100 rebate on the purchase of a C64 with the trade-in of your old computer or video game system. At the time the promo went to press the sreet price of the TS1000 had slipped to about $44.95. So lots of people bought TS1000's just to turn into Commodore and get the $55. Commodore was flooded with the little black weges, some of which had never been opened! related: - /museum/czerweny-cz-1000 - /museum/czerweny-cz-1000-plus - /museum/lambda-electronics-ltd-pc-8300 - /museum/microace - /museum/sinclair-zx-80 - /museum/sinclair-zx-81 - /museum/tonel-pc oc_id: 477 source: url: https://web.archive.org/web/20230531221915/http://www.old-computers.com/museum/computer.asp?c=477 date: '2023-05-31' --- This is the US version of the Sinclair [ZX-81](/museum/sinclair-zx-81/) marketed by Timex.
