Mr. Nagano, from Tokyo, Japan send me photos and circuit diagram of an AIM 65 clone he built.
It is a beautiful and functionally and esthetic faithful clone. In fact, he built two, one with a CPLD 3V3 version and a 5V version with a 6532 RIOT.
Features of the AIM-65 clone
Hardware
- TTY Interface (usb-serial)
- Thermal Printer
- QWERTY keyboard
- 20 x 16-Segment Display
- No Cassette Tape Interface
Power Supply
- Main Logic: 3.3V
- 16-Segment Display : 5V
- Thermal printer: 9V
Clock
- CPU/ROM/RAM:
- 16, 12, 8MHz etc. can be selected by replacing the OSC module.
- In addition, 1, 1/2, 1/4, 1/8 can be selected by the DIP switch on the CPLD board
- Peripherals ( VIA/PIA/RIOT ) :
- If the CPU clock is set to 1 or 1/2, peripherals will run at 1/4 of that frequency.
- When the CPU clock is set to 1/4 or 1/8, peripherals run at the same frequency as the CPU.
Software
The following can be selected by setting the DIP SWITCH of the FLASH memory board.
- 000: 8K BASIC/ASSEMBLER
- 001: FORTH + MATHPACK
- 010: PL65/ASSEMBLER
- 011: GWK-BASIC V2.1 for Siemens PC100
- 100: Instant PASCAL
- 101..111: Reserved
Mr. Nagano also made a version with a voltage of 5V and running at 2MHz. R65C02, R65C22, R6532A are used for it.
