Sharp CE-158 : RS-232C and parallel interface (Part 2)

It’s now time to connect your favorite pocket computer to a big Personal Computer !

First, we have to build the good cable.
CE-158 side it’s a 25 pins male connector.
PC side it’s a 9 pins male connector.

Here is the schematics
Cable

Ok ? Now we make the test on a very well known operating system : Windows XP Pro.
(But my version is in french.)

First locate the Hyper Terminal application :
CE-158_Dialog_001

When it opens you’re prompted to name the new connexion.
CE-158_Dialog_002

Choose COM1 as the connexion mode :
CE-158_Dialog_003

And set the parameters and validate :
CE-158_Dialog_004

On the parameters tab click on “ASCII configuration” :
CE-158_Dialog_006

Then check the boxes as on this picture :
CE-158_Dialog_005

Now it’s time to try receiving something from the PC-1500…

Click on “Transfer” menu and on “Capture text” :
CE-158_Dialog_007

And set the filename to CAPTURE.TXT on the primary drive’s root :
CE-158_Dialog_008

Go on the PC-1500 keyboard and type the following program and finish by the CSAVE command:
CE-158_Dialog_009

The lines 10 to 30 are send to the PC trough the CE-158 and you can see the data on the Hyper Terminal screen.
When the CSAVE command disappear from the PC-1500 screen it’s time to stop data recording.
CE-158_Dialog_010

Please control the file C:\CAPTURE.TXT content :
CE-158_Dialog_011

Is it ok ? GOOD ! Close the Hyper Terminal application.
I show you here the hexadecimal content :
CE-158_Dialog_012

Now we have to test data transmission from PC to PC-1500.
Are you ready ?

Open the DOS box and set the COM1 parameters :
CE-158_Dialog_014

If you get an error message then verify that Hyper Terminal is closed.
Otherwise you’ll get the result :
CE-158_Dialog_015

Go to the PC-1500 and update the program to this one and finish by the CLOAD command.
CE-158_Dialog_016

And on the PC side send the CAPTURE.TXT file to the COM port :
CE-158_Dialog_017

Now control on the PC-1500 that the line 20 ends now by CO 😉
Is it ok for you ?

IWS Video adapter for the Sharp PC-1500 (Part 1)

Many of us have dreamed of this device!
But his selling price was 800DM did not make him accessible to all budgets.

It was designed by “Ingenieurbüro Walter Speidel” and sold a few hundred copies. To my knowledge the IWS is the only video interface for Sharp PC-1500.

So the mysterious listing we had:

IWS interface and PC-1500 connected to the TV IWS interface in it's original box

This peripheral offers the following features:
– Playback on TV with the resolution of 25×40 or 25×80 characters.
– Input / Output cassette
– Speaker Output

Opening the IWS video interface box Inputs and outputs of the IWS video interface for the PC-1500

The save/load with the tape are faster than Sharp instructions.

It is accompanied by a user manual in A5 size.
All is correctly described, the new Basic instructions, the memory organization, except the schematics.

And there exist a 3 page correction to it :

It can connect directly to the PC-1500 but needs it’s only power adapter.

And to the printer :

Next time we will talk about hardware considerations…

CE-165 W Specifications

Yes, you have correctly read the title !
I have informations about the unfindable PC-1500 extension : the CE-165W !

CE-165W

Many of us have long sought this device without finding anything.
But luckily a friend had a few pages stapled, lost in a pile of documents.

What is the CE-165 W ?
This is not an EPROM programmer.
I guess you are disappointed …
But it is actually a programmer for the CE-160 modules.
It can program 16 once.
The verification phase is done by module.

You can download all 4 pages of specifications by Sharp.
CE-165 specifications.pdf

I will speak later of the CE-160 and we will detail its operation.
Ah, many sites say that its capacity is 16Kb … but this is false, it is 7.8 Kb.

Please, note that the CE-165W needs a CE-155 module plugged inside the PC-1500.
The pocket computer must have enough memory to store the source program.
