Sharp PC-1500 made in China… and PC-1500A too
A few weeks ago i told you about a PC-1500 made in China but now both versions were made in China too. These are not the NANFENG but real Sharp. I think that the NANFENG was the first in this country and later Sharp decided to produce on his own brand.
Do you have mode informations ?
Sharp PC-1500 serial 100xxxxY one of the first ?
Just after Christmas my friend CGH was at home for a “PC-1500 day”.
We have talked, tinkered and exchanged some machines.
I’m proud to present you this one : the oldest PC-1500 i know !
(Except his one with a lower serial number)
Externally there is no change, it’s a PC-1500.
And on the back the only difference is the serial number :
But let’s opening the machine :
It’s strapped like a A01 ROM. Uh… these straps are white ! The first time i see one like this.
We can see on the SC613128 IC that it’s a A01 ROM.
The biggest white strap is mine, to repair a memory access problem.
Do you see the diodes on straps ? First time too…
Ok, more ?
The display board version is F2025, the oldest i know.
And the mode exciting, the CPU board !
There is no board revision !!!
If some of you have similar PC-1500, please, contact me to compare boards versions. 😉
And if you don’t have… this is a new quest !
PC-1500 28Kb – Part 2
This PC-1500 is more than an updated version with huge memory amount and double-speed oscillator.
It’s one of the firsts samples of the A04 production.
In this picture you can see the ROM version on the SC613128 IC.
Do you remember the A03 versions ? They have blue straps… like here on the display board :
And now lets see under the memory extension…
The board shows many blue straps like the A01 and A03 versions :
Sure this is a rare item for collectors.
It’s serial number is 20024876.
Who owns a such collector version ?
Take a screwdriver and verify your PC-1500s 🙂
Thanks again to Lukas ZELLER for this gift.
PC-1500 28Kb – Part 1
Lukas told me about his gift that there will be a 28Kb PC-1500.
This was a good news !
But this is more than a good news.
Lets me present this updated machine.
Opening the CE-150 box shows us some nice things.
Do you see what i mean ? Examine this picture carefully…
First there is a sticker “28K”. This means that the memory size is 28Kb. It’s the maximum reachable on this pocket because of the display addressing method.
Let’s open the machine…
Here is it :
This extension it made of 13 x 6116 ICs and present a total amount of 26KB of memory.
It’s a very professional board. You can see where the RAM pins are placed ? Simply on the holes between sides. Well done guys !
This board is named “DF1SE PC 1503”. (If you know more about it then use the contact form to tell it to me.)
Second, there is a switch on the PC-1500 side :
Do you know why ?
The LH5801 microprocessor is driven by a 2,6Mhz oscillator.
In 1982 it was fast ! In 1984 it was slow ! lol
This button switch between the 2,6Mhz and a new 5Mhz oscillator. Yes, the twice !!!
Uh… this has some back effects to the real time clock… but the speed is here !
The printer case and the pocket pouch have being modified for the switch.
Third, there is a very nice update of the printer’s door.
A little black plastic strap help the opening.
Next time i will explain something very particular on this PC-1500.
Do you have an idea ???

PC-1500 : The Book of the Grail
Who has not wanted to know exactly what happens in the machine?
I remember rumors that spoke of an amazing book in which we could understand everything … on the PC-1600.
Oh yes, I searched long and I abandoned my quest for the Grail.
6 months ago, a friend offered me some books on the PC-1500.
He told me “there is a book with commented ROM listing.”
I thought it was for the PC-1600 but he told me the title: PC-1500 Intern
What?? For the PC-1500?? Great!
Wow, what a thrill opening my package and discovering this book among other treasures …
Here it is:
PC-1500 Intern
the book and the patch sheets
A sample page :
PC-1500
The European and USA version released in 1982.
The board is final, the production runs !
