Here is one bonus for you : the original MC-12 color advertisement.
And a big thank you to my friend Ray for this advertisement stored all these years
(And no thanks at all to BMC for their “no help”)
BMC : The MC-12 (Bonus)

Category Archives: 4-Extensions
BMC : The MC-12 (Part I)
This is MC-12A’s little brother in size and expandability.
It’s more compact and feel more robust.
And it can be stored and used in the CE-150 case
As you can see it’s not designed to be used without the CE-150. The main I/O are present.
But there is no other I/O connectors except power ones.
No V24 or digital I/O expansion port.
Next time we will open the case š
BMC : The MC-12A (Part III)
Let’s go for the technical view.
You can first download this advert in german language :

CE-158 : The advert
The CE-158 folder is not complete without this advert :
BMC : The MC-12A (Part II)
The BMC’s ROM is copyrighted RVS, Rasso Von Schlichtegroll !
This is a very good surprise, isn’t it ?
Then we have a very nice software to drive the BMC hardware.
The system brings us these new instructions :
MC-12A Basic instructions and codes
| AUTORANGE (E384) | INFUNCTION (E399) | SCREEN (E381) |
| BUFFER (E363) | LOADBUFFER (E3A6) | SELECT (E3A9) |
| BUFLEN (E350) | MCON (E38A) | SETCOM (E3AF) |
| BUFINIT (E3A1) | MCOFF (E38B) | SETRANGE (E389) |
| BUFNUM (E351) | MULTIMETER (E39B) | SETTRIGGER (E395) |
| BUFREAD (E3A3) | OUTCHA (E382) | SETSCANTIME (E396) |
| BUFOPEN (E3A4) | OUTSCREEN (E393) | SETPREHIST (E397) |
| BUFWRITE (E3A5) | PREHIST (E355) | SETFUNCTION (E398) |
| BUFRANGE (E364) | POSITION (E356) | SLEEP (E39E) |
| CHA (E361) | PLOT (E39A) | TRIGGER (E354) |

| DBUFINIT (E3AB) | RELAY (E39D) | POSTLOAD (F0DC) |

| INIT (E390) | SWITCH (E380) | |
| INSCAN (E3AA) | SCANTIME (E353) |
The last two (POSTLOAD, RVSLOAD) have special functions.
RVSLOAD loads a sample program originally stored in the ROM :
(Thanks to my new tools for the CE-158 with syntax highlighter)
But if you use POSTLOADĀ the program is bigger !
Download this program : MC-12A_Forth_Full.TXT
As a big bonus, here is the user manual for the FORTH language :

Next time we will discover the MC-12A technical side.
This will be a little boring but necessary.
CE-158 : Do you need some tool ?
Do you need some tool to use easily your CE-158 ?
My new software is now in BETA version and will be soon available.
Features ?
Communicate with your CE-158 using CSAVE, CSAVEM, CSAVEr, CSAVEa formats.
Application menu reflects your directories for .BAS and .BIN files.
Syntax editor with completion and code snippets.
ā¦
Currently testing the BETA 0.1 and all works great.
Features to include ?
Data exchange with PRINT.
Basic decode routines when using CSAVE
ā¦
Do you want some other features ?
BMC : The MC-12A (PartI)
The MC-12A, the most advanced acquisition tool.
As you can see, it fits perfectly with the PC-1500/CE-150 system.
What can this do ?
– Digital Multimeter -5V to +5V
– Data logger
– Transient
– Fonctions generator
– Data analyzer
– Regulation/Control unit
How can it communicate ?
– 5 input channels
– 2 analog outputs
– 4 CMOS switch
– 2 output relays
– 24 pol. l / O port
– V.24 interface
– 60 pins connector to PC-1500 or CE-150
It’s a strong tool, isn’t it ? It’s as wide as the CE-150.
The power supply adapter EA-150 is plugged directly in the MC-12A and is transferred to the CE-150 with a grey cable.
A very nice idea !
Removing the CE-150 is not really easy. You have to remove 2 screws and move the printer to separate it.
DO you see the white tube on the metal plate ? It goes directly to a hole under the CE-150.
Here is the CE-150 connector :
Now let’s opening the MC-12A and see inside.
There are some options installed. A really good thing ? All the ICs are on sockets ! Easy repairing…
There is a place on the left with corroded marks. It’s the battery.
The whole system can be used out of 110/220v ! You can take it and go on site.
Let’s open a bit moreā¦ there is a RAM and a ROM. Two sockets are unused for future extension.
The ROM IC will give you a really good surpriseā¦ stay tunedā¦

Sharp CE-158 : Hardware side (Part 4)
It’s now time to open the box.
The CE-158 is a nice extension with a multi-board construction.
On the bottom there is the main electronic board with the LH5801 multi i/o IC.
On the middle there is the RS-232C interface.
And on the top there is the Centronics interface.
The battery pack is 500mA/h 4,8v.
I know two versions of the CE-158 but don’t know the differences
Here are the Sharp specifications :

And the Service manual :

I have found the connexion cable for 2 CE-158 in a chinese book :

Sharp CE-158 : Tandy RS-232C interface (Part 3)
As for the PC-2 Tandy’s choice was to make the difference : RS-232C but but parallel interface.
This was a manner to reduce price.
I don’t know anything about the original packaging but all accessories are same.
The manual is smaller, the keyboard mask adapted to the geometric keyboard.
And the is no difference when connected to the black printer :
Next time i will show you the hardware of booth interface versions.
Stay tuned…
