I remember that exact ad. I'm old.ðŸ˜.
Wheagy@reddit
I bought one based on this ad back in the day. Took a long time to arrive in the states. Good times. I still have it.

I recognize this ad from back when I got mine too. That $149 was steep but I’ve been programming computers ever since, so it was well worth it.

My trash 80 has 4k with 8k basic.

Nice of them to throw in the manual for free.
Glidepath22@reddit
It’s a $10.95 value.
icedcornholio@reddit
Really though it’s priceless.
Academic-Airline9200@reddit
American express!
RebeccaBlue@reddit
It was actually a really good manual... Not only explains BASIC, but had a list of Z80 opcodes, too.
Glidepath22@reddit
I practically memorized IBMs Basica documentation, they don’t document like that anymore.
RebeccaBlue@reddit
Yeah, the manuals that came with the XT were amazing. The whole BIOS listing was in there.

This reminds me of- how did we all know Sys 64738 reset a c64…was it in a manual?
Many_Dragonfruit_837@reddit
I remember sys 49152 being the command to start many programs..0xC000.
Block of memory outside of the BASIC area if I recall correctly.
RebeccaBlue@reddit
It might have been- there were definitely some PEEKs and POKEs in the C64 manual, although, I think I learned about it in Compute magazine. I also bought the "Mapping the C64" book, which had a ton of stuff like that.
SomePeopleCallMeJJ@reddit
Yup. One of the best from that era, IMHO.

I still have the Timex Sinclair 1000 complete with 16k memory module. Lost the power adapter though but it should still work if I can figure that out.
droid_mike@reddit
You can use an Atari 2600 adapter... Same tip (+) and voltage (9v). Some of the newer adapters are low on amps. Check for like 700-800 mAmps.
The_WolfieOne@reddit
Cool, thanks 😊
venerable4bede@reddit
I had the bootleg 64kb memory module, for super extra games of Snake (or something, I don’t know. I got tired of typing in games on that damn membrane keyboard)
Away-Squirrel2881@reddit
I have one of those and it’s packed up in a Ninja Turtles plastic lunchboxÂ
Responsible_Hat_6056@reddit
I still have two of those in the basement somewhere and the wife's BBC Micro too. BASIC gave way to assembly and FORTH, early analog to digital processing, peer to peer comms, homebrew expansion cards. I owe a lot to Sir Clive.
brettonart@reddit
My first computer. I was so frustrated with it, and with the 16k expansion module that wobbled and disconnected, that I boxed it all back up and took it back to the store I bought it from.
Rockola_HEL@reddit
First computer I saw in someone's home.
Sample_And_Hold@reddit
My first computer was a ZX81 clone with 2 KB RAM, later expanded to 16 KB. I also did a couple of simple mods: reverse video switch and reset button.
masmith22@reddit
Nice, I owned one of these back in the day.
Ornery-Practice9772@reddit
Was the printer released shortly after?
the_bashful@reddit
Inspired an entire generation of British coders.
DrDynoMorose@reddit
I still have mine, and it’s Spectrum bigger brother
Trenchbroom@reddit
This is an ad from when Sinclair was selling them direct to the U.S. before Timex took over.
AirlineOk3084@reddit
I bought the kit when it first came out. I believe it was $99.
