Tandy a full system closed to Sharp one.

Most of you better know the Sharp system. Why ?
Maybe because Tandy/Radio shack didn’t follow Sharp along the years for this pocket computer.
Here is the Tandy system :
EMI_2609

We know some PC-3, PC-4… but the PC-2 is still at the PC-1500 step.
I don’t know exactly why…
Someone can help me with this item ?

I already presented the PC-2.
To be precise I presented one version of the machine.
Yes, you really read “one version”, maybe the third one.
On the picture you can see lot of blue straps and a IC named “SC613128” with “A03”.
TRS-80_PC2_004

We know it’s the firmware revision. Then A03 seems to be the third.
Does someone have the first and the second ? Uh… that sounds mysterious…

I have the fourth !
Tandy_PC2_A04

As you see, no blue straps on the CPU board.
In fact it’s exactly closed to the PC-1500 evolution.
But… one moment please…
With some friends we had a really interesting discuss about Tandy and Sharp.
Like the chicken and the egg … which came first?

After reading this first article you have more questions than answers, isn’t it ?
– who have the versions one and two ???
– who can answer the chicken/egg question ???
