Also it has an IEUG "Greatest Hits" tape.

I never heard about this. Google> http://www.computinghistory.org.uk/det/32329/IEUG-s-greatest-Hits-Vol-1/

Book is rare.

This is why I will bid on these!

I think I uploaded it many-many years ago. But there is again.

ah thanks
this is a demo from it (modified because of the "tape:" references)

This is why I will bid on these!

Then, I shouldn't bid for it, should I...?

Sorry, it was only a rather competitive joke...

But on the other side I would like to get one original parallel cable if this is really one of them. And also an original RGB cable if you have a spare one(you showed one of them on the pictures you sent me). I think that these connectors complement a lot with the overall design of the computer. My hand made ones adapt very good to the holes and edge, but aren't so stylish.

About the other connectors... EnterMice covers the rest of the holes much better....

No, I'm not interested on the tapes, thanks, I don't want to return to that era.... But may be my friend Sinclair200 can buy you some. He is a collector of all type of things. I can ask him. Put a price.

I can create topic where put all lost things (books, magz, soft) if you wish.

Good idea! Once I started made a list of missing programs.

WINDOWS I. Interlace Technic

It's IS-BASIC extension. http://ep128.hu/Ep_Util/Windows.htm (hm... it's non interlased)

I have been reading the Centrum catalogue. It is incredible, there are a lot of missing programs with suggestive title.

Do you think they where real, or just stuff to fill the list?

After the first 15-20 years I started think these are fakes. But in the last ten years we found many never seen things (for example the most of Level 9 adventures). Soo probably not (all) fakes

Have you heard of these programs from other users?

What I'm wrote to the list is the never seen programs, and some what we have but don't have the original tape/disk/cart release.
