can't find "family tree" of Sharp pocket computers

[vaklaff]

Hi

Some time ago I came across a web page with a graph or "family tree" of all those Sharp pocket computers of the BASIC era. More or less like http://pocket.free.fr/html/sharp/sharp_e.html but expressed graphically and with little images IIRC. I even have a vague feeling it was linked from this very forum but I may be mistaken. Anyway, I can't find the page any more. Does anyone know the page? Please share the link!

Thanks in advance!

Never mind. It's http://retropc.net/ohishi/museum/pc.htm. Lost half an hour, couldn't find it, wrote the question above, and only then found it myself in half a minute. Sigh.

Always works! Great finding though, thanks for sharing. There are linked write-ups for many of the machines.

Thanks for sharing this! I've not seen it before. It is reminiscent (maybe even a copy) of a display I saw in a Sharp office in Nara (outside Osaka) where most of the engineering for these was done. It's an impressively large number of models, far more than most folks assume existed.

Baldwin's Third Law of Metafoolishness: a certain percentage of the questions you daily encounter must be asked publicly before you can find the answer yourself, thus ensuring you don't get a big head.

Believe me, I am the poster child for this happening!

Something similar:
I was waiting for a back-ordered component for a project at work, so I ordered one myself from a place that had it in stock.

Guess what got put on my desk at the same time it was getting delivered to my house?

This family tree is super nice!

It seems to leave out some older predecessors that are also designated as "PC" models. I believe the first (or one of the first) Sharp "PC" model designations was the Sharp PC-1001, a programmable desk calculator from 1973. The PC-1001 has a Rockwell PPS-4 microprocessor system, one of the first microprocessor systems competing with the 4004. But the PC-8101 was a non-programmable early LED calculator from 1973. I suspect "PC" later became associated with Sharp Pocket Computers, starting with the PC-1200/1201 according to the family tree. But like the PC-1001, the PC-1200 and PC-1300(S) are not BASIC programmables.

Yes, I know, I’m very happy to own a 1200 (classic keystroke) and a 1300 (keystroke but advertised as “minifortran”). Actually that’s how I finally found the page: Wait, what if my memory fails me and the page has more than BASIC machines only? Let’s add these two to the query! And that made it.

Very nicely put!

Hmm… a suitcase with $25,000,000 you won in a lottery and didn’t know about it?
