BMC : The MC-12 (Part II)

Inside the MC-12 it’s a professional assembly. As in the MC-12, all ICs are on sockets.
No battery here, the system needs a power adapter.
The build is same, a main board and piggy-pack modules. We can see some double connectors on the right for, maybe, some filter ?
Under the AD/DA board we have :
– 2 RVS Roms with the firmware
– 4 static memory ICs with a total of 8Kb !!

There is a Basic program stored in the Rom. It’s the named “MC 12.QAS”
BMC_MC-12_QASDownload the user manual

The program is a good example for the new Basic instructions :

And here is it running :

BMC_MC-12_015 BMC_MC-12_016

Next time we will the optional modules and some industrial use.

BMC : The MC-12A (Part III)

Let’s go for the technical view.

A new one in the family : NANFENG PC-1500A

After the Blue Brother, a very rare PC-1500, i’m proud to present you the number 10 : NANFENG PC-1500A.
This one is the only one i know as a non Sharp PC-1500A.
It’s the rarest one !


In details you can see the NANFENG logo.
It’s not a paint add-on, it’s like original Sharp embossed logo.

On the back it’s like the other Sharp, The CE-161 memory module is a real Sharp one.

But the sticker is different and shows “Made in China” and the brand is NENFENG.
The serial number is “NF 002/83 J”. This means that it’s one of the firsts PC-1500A.
Was this a preproduction lot ?
I’m surprised that the front panel is EU/US and don’t have Katakana chars.
The screws are very cheaper than the originals.

Inside, on the boards nothing differs from the PC-1500A.

But the metal parts are wider, yellow/orange color. And the screws basic.

Well, is it really a chinese production ? YES only for font parts.
The brown paint is very similar to the Sharp but a little bit darker.
The varnish is not that brilliant.
The symbols near the function keys are brown and not orange.
The beige paint is darker.
The chars on the keys are bigger.
The CL key is a little bit transparent.
All this seems low cost.

This is the only one sample i know for the NANFENG PC-1500A.

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, one of the first EU/US version with A01 ROM

If was hard to find it but here is it : one of the first EU/US version with A01 ROM.

This one is in a mint state. Lucky guy, isn’t it ?
On the front side nothing can distinguish it from the successors…


On the back no more difference. But if you look closely on the serial number there is a big difference : it begins by “20000…” and ends with 892. This one is in the first 1000 sold items. For the Japan version you will have to find a serial number beginning by “1”

PC-1500_A01_002 PC-1500_A01_003

Inside we see lot of blue wire straps. It happens sometimes in the early A03 versions.

PC-1500_A01_004 PC-1500_A01_007

Let’s look closely on the boards…
The CPU board has lot of errors. On the keyboard/display board you can see the SC613128 ROM IC with A01 on it.

PC-1500_A01_006 PC-1500_A01_005

Now we remove the board from the front side.
The display board revision is F2075

PC-1500_A01_009 PC-1500_A01_010

And we do same with the CPU board and see F2076.


I will soon make same with the other versions.
See Sharp Technical Reports for ROM differences :

And same with the printers because they have many revisions and at least 2 ROM versions

Your Sharp CE-150 needs repair ?

The main problem on CE-150 is the battery pack.
This item needs to be kept in charge.
But after years in your attic…

The battery pack leaks and can damage the electronic board.
Sharp did a mistake when designing the CE-150.
Without battery pack the printer is unusable except for tape operations.

Do you want to repair it ?

Look at this video tutorial offered by Kai :
