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”)

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 !
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 😉
BMC : The MC-12A (Part III)
Let’s go for the technical view.
You can first download this advert in german language :

Manuals update : Japan PC-1500 Instruction manual added
Yes ! The instruction manual in Japan is here !
But there are some other manuals missing… can you help me ? 😉

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) |
| COM (E3AE | RANGE (E362) | TRANSREC (E39C) |
| DBUFINIT (E3AB) | RELAY (E39D) | POSTLOAD (F0DC) |
| INCHA (E386) | ROM# (E357) | RVSLOAD (F0FB) |
| 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 POSTLOAD 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.
…
Currently testing the BETA 0.1 and all works great.
Features to include ?
Data exchange with PRINT.
Basic decode routines when using CSAVE
…
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 more… there is a RAM and a ROM. Two sockets are unused for future extension.
The ROM IC will give you a really good surprise… stay tuned…
