Do you know that the Sharp PC-1500 was used in the army ?
In this picture we can confirm with a big surprise : it was in the Chinese army !
Who can believe this ? A Japan pocket computer in the Chinese army… but maybe was it the Nanfeng version…
I don know much about it’s use but it’s in a rugged box with a waterproof keyboard mask.
The logo seems to be Chinese Air Force or Airborne.
I would be please if one of my Chinese readers could tell us the item’s story and send us more pictures.
Can someone help me to get one ? I really like it !!!
Do you know similar use in your country ?
This is one very rare item produced only with only 250 produced.
If you own it would you share some pictures here ?
I will be back from holidays in a week…
The classic case exists in two countries Hungary and Brazil.
In Hungary we have two versions for the Hiradastechnika company.
They are very closed to the Sharp but with some differences.
For the PTA-4000 the color is between brown and orange and the plastic fell low-cost.
And the inside zone delimiters are only welded at the bottom, nothing on the sides.
For the PTA-4000+16 it’s the classic brown color
With the same problem for the separators
And here are the two in the same pictures :
For Brazil it a luxurious case, like a jewel case ! My preferred !
There is a special compartment for a memory module.
We all have this accessory with our CE-150 : the case.
But do you know all the cases ?
We have the classic Sharp :
Brown, well designed with 3 zones for CE-150, paper rolls and power adapter.
The rare CE-154 !
The top-most accessory.
The Tandy version.
This one looks very nice with two pockets for power adapter and accessories.

Impossible to find the box. Do you have one ?
The boards and the 74HCxxx components are here.
The memory ICs will arrive soon.
Here is another document from Reiner PUCH.
If you want to write Basic keyword yo must read this… after translation from German.
It explains how to give a code your new Keywords and it’s relation with the PU and PV cpu flags.
Can someone translate it ?
And if you own other documents from Reiner PUCH please contact me.
Ok, my tests are OK on the prototype board.
Here are the module features :
– Reference TE-1508
– 512KB of static RAM
– 16 pages of 32KB located in the ME1 zone
– Software selection of the page
– Software Activation/Desactivation (for example the IWS video interface uses same zone in ME1)
– Optional CR-2032 backup battery
– Optional write protection by jumper.
The page selection uses a very special feature of the LH5801 processor which was never being used before… because Sharp never routed this pin !
The data bus can work as a multiplexed bus like the Intel 8052 from the MCS51 family. It means that at one time data are on the bus and another time it’s something else. And this is f… good feature ! I don’t have to use many logical cells. Page 42 of the Technical Reference Manual describe it as the ATP instruction. It pushes the accumulator value on the data bus and provides all signals to store it in a latch. And here we just have to plug an octal latch.
Manual routing is done !
Installing it in your Sharp PC-1500(A) will need some wrapping wires…
I need some tests with the final board and i will tell you the price…
Is it enough to store your programs ? 😀
