Hallo, I have built some 2650 computers for educational use in s.ls (Hamburg, Germany in the 1980s). I still have got some working systems. For more infos, please reply.

That's cool, are there any more details about this machine? I assume you are intending to put a PIPBUG EPROM in that socket at some point?

I'm impressed! Can you tell us some more ...

I've recently been trying to track down the date when the S2650 first became available as the question has been asked on Wikipedia. The earliest reliable reference I have been able to find so far is in an article in Computerworld (via Google Books) dated 4 Sep 1974 where it mentions the 2650 in a list of "new and available systems" to be discussed in a survey session titled "Microprocessor - The 2nd-generation" at Wescon 74. Can anybody identify an earlier reference than that?

Regards,
Chris

>I am curious now, you made a compiler of some language for the 2650 ? Do you still have it ? I wonder, has anyone ever written some sort of OS for the 2650 ?

For languages, interpreters for BASIC and FORTH have been dumped. For operating systems, there are 8 which have been dumped: PIPBUG, BINBUG, the Elektor TVGC BIOS (aka Hobby Module), the SI50's USE BIOS, the CD2650 BIOS, the PHUNSY BIOS, the Dolphin BIOS, and the Chaos 2 BIOS. You can get all these, and further details about them, at my site (http://amigan.yatho.com). All of them are written for slightly different hardware configurations, but all are 2650 programs.

But you are correct: the vast majority of 2650 software, especially games and application software, has not been dumped. :-(

Hi Sig2650 nice to see you here.

I am curious now, you made a compiler of some language for the 2650 ? Do you still have it ?

I was trying to locate a bit of SW around for the 2650 but it really seems
there's no very much of it, all I can find is some thingies about some
Australian computer magazine(s) that published quite a few about HW with the 2650 but not very much about SW.

I wonder, has anyone ever written some sort of OS for the 2650 ? Is anything of that still around that could be recovered ?

It would be interesting some sort of "old SW restoration project" :)

Hello,

Since the project was cancelled by Sigi, I had a lot of time. The first thing I did was the compiler on the systems we had in house. The second thing was the board for our customers (none) to use for debug of the chip and their systems. Never actually used the board myself as I left before it came out of fab. But I am very happy it worked the first time, with no defects. The 2650 was the same way. From design to fab with no defects.

Thanks for your interest, J.
