Description

The HB-501 is the combination of the HB-201 with a data recorder, which looks quite similar to the separate SDC-500 Bitcorder. It has been released only in Europe. It was only available in black. The following models exist:

  • HB-501F: model for France with AZERTY keyboard layout
  • HB-501P: model for other European countries with QWERTY international keyboard layout including a £ key

The machine comes with a Personal Databank with support for saving on cassette tape or the HBI-55 data cartridge. It's the same software as on the HB-101P and HB-201P, it's however not built-in as firmware, but provided on tape.

Unlike the HB-201, there is no place to store the power cable underneath, and the retractable carrying handle has also been removed.

As an option, a removable stick can be added in the middle of the cursor keys, which can be used as joystick. The back of the case has a location to store the stick during transport.

Introduction price: ƒ 999.

Specifications

The HB-501 has two cartridge slots at the top of the computer, a Z80 from NEC (D780C-1) and a MSX-Engine from Yamaha (S-3527). The PAUSE button halts the CPU.

The VDP used in the HB-501P is the Toshiba T6950, which does not support some undocumented features of the Texas Instruments TMS9918, TMS9928 and TMS9929 VDP's which can cause some compatibility issues.

Connections

  • RF output (only on HB-501P)
  • Monitor connector with sound and composite video outputs (6-pin DIN) on HB-501P
  • RGB output (SCART-PERITEL) on HB-501F
  • Tape data recorder connector (only on HB-501P)
  • Centronics compatible Parallel port for a printer
  • 2 general connectors (Joysticks, Mouse, Graphic pad, Paddle controlers, etc)
  • 2 cartridge slots

Upgrades

As designed, this computer is compatible with the addition of a disk drive, contrary to the HB-55 and HB-75 machines. Some modifications have been made to allow the addition of a disk drive. The insertion of the HBI-55 cartridge in a free slot does not disable the disk drive.

Repair

The built-in Bitcorder is actuated by three Rubber belts (not easy to replace for everyone).

Approximate specifications:

Belt 1 : D = 47mm, W = 1.2mm (square belt for the counter)
Belt 2 : D = 46mm, W = 1.2mm (square belt for the motor)
Belt 3 : D = 36mm, W = 1.2mm (square belt for the motor)
