Do you remember the PC-1500 RP2 found in Brazil ?
This new one is the RP and it’s the same for the printer.

This is a full set with all accessories and manuals. The instruction manual is only a bad copy.

The case is very clean ! And all accessories are present : power adapter, pens, paper, cables…

And the papers too : connector cover for the printer, sticker for name.

And the big surprise is the PC-1500RP 8K memory module. Uh, all seems to be named PC-1500RP…

The case is like the one the the PC-1500RP2 but with two rivets on each side. This makes it stronger.

Differences between the RP and RP2 ? None !

Each time the serials are same for the pocket computer and the printer.

In conclusion i think the RP version is the PC-1500 without memory module (or with 8K) and the RP2 is provided with the 16KB module (Remember the PTA-4000 and PTA-4000+16).
Not much differences but we can consider the two versions.
Now we have 11 PC-1500 versions !

Like Status Quo, in the army now, oh-oo-oh…

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 ?

CE-150 cases part II : for specific countries

Leave a reply

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 !

TE-1508 : Internal 512KB RAMDisk !

2 Replies

Ok, my tests are OK on the prototype board.

TE-1508_RAMDisk

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…
TE-1508_Reduce

I need some tests with the final board and i will tell you the price…

Is it enough to store your programs ? 😀
