My old equipment :)


Your old, I had & I gave.

There are appliances, witch I had in possession. I made their photographic documentation so you can see.

NEC PC-8300

In 1987, the NEC PC-8300 replaced the NEC8201A produced since March 1983.
My copy of the NEC PC-8300 was made in 1989.
In July 1990, the production of this model was completed.

The NEC PC-8300 measures 8.5 "x11" x 1". It has an LCD screen, displays 40 characters in 8 lines in standard mode, weighs less than 3.5 kg and can work from 18 to 20 hours on four AA batteries (mine powered in a basket of 6 batteries).
The built-in software includes the N82-BASIC interpreter, ASCII text editor and telecommunications software for use with a serial port and / or modem.
On the back wall you will find a 8.5V power socket from the left. Then, the PROTECT (ON-OFF) switch prevents data from being entered into the No. 2 memory if the memory has been extended to additional banks. The data in this bank is then protected against accidental loss. Next to the switch is the RESET button.
The next is the FDD Port - to connect the Micro Disk PC-8231A-KD module. The telephone port is the socket for the 8 pin plug next to it is BCR - 9 pin port for connecting the code reader. The centronics paraller printer port is located above the RS-232C port. The last the port is CMT for connecting the PC-8493A data recorder.
The right wall has a battery recess, screen contrast adjustment and a computer switch (1 ON - OFF 2).
The left wall has only a hollow recess of the expansion module slot.
The lower housing plate has a BACK UP POWER (ON-OFF) switch and a fully visible socket on the system battery. Two holes are interesting. One covered with a plate screwed with three screws and the other smaller with a plate for latch ("there were no screws).
In the larger hole the majority are covered with an aluminum foil-protective sheet, which I did not move. Two ROM memories are visible:
- ROM0 831000-438, N83A BASIC (C) 1986 MICROSOFT 8929 Z13
- ROM1 (programmable) TOSHIBA TC57256AD-15, JAPAN 8919EAI, VPP 12.5V
In the smaller opening you can see systems with M6, M7 and M8 symbols with symbols: 9G3 1, HD44102CH, JAPAN (according to GOOGLE: Dot Matrix Liquid Crystal Graphics Display Column Driver).
Partially, the circuits cover the PCB of the PLX256CH1X module with a 16-track tape.
This computer lay for a long time in anticipation of further work. It is in the condition I bought it. It was not cleaned, because traces of exploitation and storage are a valuable source of knowledge about possible equipment failures.
The PC-8300 required a new liquid crystal display. I decided to give it to another person for repair or for part.
Good signs and stickers have been kept in good condition. It is FCC ID: A3D9SBPC8300.
NEC PC-8300 has much to do with Radio Shack Model 100 / Model 102, Kyocera KC-85 and Olivetti M-10.
