TE-1507 : Prototype updated

Hi, In my PC-1500 i had problems with the first TE-1507 version using Xicor memory.
It was impossible to write something in an unprotected X28HC256.
http://www.pc-1500.info/2015/07/30/te-1507-the-memory-module-for-developers/

The Team1560 needs were to have a big system RAM and a place to test system ROM extensions.
Done ! The TE-1507 is now working with 2 RAM ICs and the R/W protection is done by jumper.

Here are some pictures the prototype :

This one, number 3, is reserved for…….. ? Stay tuned 😉

The release version should be available in one month.

Happy birthday !!! The second candle !!!

Hi all my readers !
Two years ago when i started this website i didn’t imagine to find all these informations about the Sharp PC-1500.
Did you imagine that this little pocket computer was distributed all over the world ?
Under other brands like Hiradastechnika or Nanfeng ?

It’s always a pleasure when a reader contact me and tells me it’s story with the PC-1500.
But it’s very rare ! Who wants to share his experience and knowledge ? Send me some articles with pictures and i will publish it !
Do you have some old program tapes ? Do you want to teach machine language programming in a set of articles ?
Your English language writing will sure be better than mine ! lol

300 000 visits since last year… incredible ! Thank you !
I know that my visitors are from lot of countries, some close to me in France like the Silicium.org forum, some from the other side of the planet like Neil in Australia or Waon in China, Toplica in Russia… Thank you for following the SHARP PC-1500’s story.

My next big task will be to contact Sharp in Japan and to ask for their help.
They may have lot of documents to share with us and shipping a parcel with rare informations, schematics, books, pictures, peripherals (like CE-165), is not an excessive cost ? They may have a museum, isn’t ? My website is the PC-1500 museum 😉
Please, Sharp company, read this page http://www.pc-1500.info/donors/
Some of you are already generous donors and i thank you again and again !!!

Who can answer this question : Which is the last serial number signification ?
My suggestion is something like the factory or the target country…

Ok, it’s time to close this second year with a Graal : the Blue PC-1500 in the rare Japan case !

The Sharp CE-515P printers (Part II) : European/US version opening the box

The box don’t have the classic PC-1500 peripherals brown look.
It’s the for the next generation, the PC-1600, and have a nice blue color.
The parcel looks strong and the printer seems to be well protected.

The inside part is made of two blocs of polystyrene. The user manual is on the top.

And on the top bloc we discover places for a paper roll and 3 pens sets. Nice idea !

Next time we will open the printer 🙂

Tape of the week : URSoft Tool Kit V1.1

TapeOfTheWeek
I begin a new article type : Tape of the week.
Months after months i have found software on tapes and will offer you these oldies 🙂

This software comes from Switzerland, a hundred kilometers from home.
The tool kit V1.1 is written by Urs RIBI from the URSoft company.
URS_RIBI_URSoft_ToolKit_V1.1

It’s a set of new basic keywords :
REPEAT… UNTIL, WHILE… WEND, LOOP X MAL… LOOPEND, INITLOOP, POP, DATE$, ZEIT$, CLOCK, SECONDS, JAHR, GET , SWAP, SORT, FRAC,HEX$, BINDEC, BINSTR$, INC, DEC, INVERT, PRON, PWROFF.

This kind of package is rare and each time it’s a real pleasure to discover new keywords.
This one may be inspired by some PASCAL language.

You can download the files here : Package and Manual
There is a special file named URSOFT.KEY in the package. It’s to use with Torsten’s software WAV2BIN and this adds these new basic keyword when converting a Wav file to Bas file. 😉

In the manual you will read something about a TOOL KIT V2.
If someone own this kit and want to share it with us… please contact me 😉

H.-G. SCHLIECKER : ROM-Unterprogramme I

If you want to learn what’s in the system ROM then you must know H.-G. Schliecker publications !
Do you remember the “PC-1500 INTERN” with the whole disassembled and commented ROM ?

Today i have something all the assembly language programmers are dreaming to :
SHARP PC-1500 ROM Unterprogramme I“. When learning machine language programming you discover that there are 128 system routines you can directly call by short instructions. For example, some ones can handle Basic tokens and their parameters, others can execute mathematical calculations on real numbers…
But who knows all the 128 routines ?

This very rare paper describe all of them with calling parameters but it’s in German language 😉
As it’s named “ROM-Unterprogramme I” i suppose that a number II exists somewhere…
Maybe one of you can help me to find it ?
