Here is my full SHARP system “in box”.
– PC-1500 small box
– PC-1500 big box with manuals
– PC-1500A big box with manuals
– CE-150 printer and tape interface
– CE-151 4KB memory module
– CE-152 tape recorder
– CE-153 Soft ware board
– CE-154 Briefcase
– CE-155 8KB memory module
– CE-156 Katakana software tape
– CE-157 Katakana ROM module
– CE-158 RS-232C and parallel interface
– CE-159 8KB memory module with write protection
– CE-160 7,8KB Read only memory module
– CE-161 16KB memory module
– CE-162E Tape and parallel interface
The CE-163 2x16KB memory module is missing.
Impossible to find the box. Do you have one ?
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 ? 😀
I’m testing a new hardware to take place inside the PC-1500(A).
The schematics is OK, the circuit board is manually routed.
And i’m testing it with some classic DIP components.
This new module will be the TE-1508, a 512KB RAMDrive.
It’s like 25x the maximum user RAM area.
All this memory is organized in 16x32KB pages with a write protect jumper and a CR2032 battery.
It’s in the first half of the ME1 zone and can be disabled by software. (Remember that the IWS video interface uses the same ME1 zone.)
But installing it inside the PC-1500 will be a big job.
I remember having a non Sharp tape recorder… it was one from Realistic very closed to the CE-152 : the Minisette 9 !
It’s the landscape version of the CE-152. Buttons, case, counter, strap… all are very closed or exactly the same as on the CE-152.
But it’s not the CE-152 clone… stay tuned… 😉
This morning i received a mail from an australian friend, Bronte, telling me about belts problems in his CE-152.
Do you have problems with your Sharp CE-152 or want to look inside ?
Someone explains this tape recorder better than i can do : www.petervis.com
You can find the belts on eBay. But some vendors are very expensive… search… search…
For example : this one in China or this one in UK
Hello, we all have to thank AXEL for these documents !
I contacted him some days ago about his MC-12A picture on his website :
He searched everywhere in his hard-drives and found two scans of the manuals.
The pictures had black margins with text inside.
With my favorite image processing software (Aperture) i corrected it, sometimes with letters by letters words reconstructions.
Here are the manuals :
Thanks you again Axel !
