Description

For his 3rd series of MSX1 computers, Sony has choosen the simplicity. The design remains similar to the HB-101 and HB-201 series, but all the extras such as firmware and pause or reset button have been removed. The following models exist:

Product Region PSU Keyboard Video and audio out Colour
Sony HB-10 JP 100V 60Hz QWERTY w/JP ANSI RF, Composite video and audio Red, Black or Gray
Sony HB-10B UK 240V 50Hz QWERTY with £ key RF, Composite V+A DIN Black
Sony HB-10D DE 220V 50Hz QWERTZ RF, Composite V+A DIN Black
Sony HB-10P NL 220V 50Hz QWERTY with £ key RF, Composite V+A DIN Black
ES QWERTY with ñ key

The power supply is external and its connector is proprietary, being similar in shape but different in size to the mini-IEC used in Sony HB-F1 and Panasonic FS-A1 computers. The output voltages also are not the same (6V-900mA, AC16V-160mA).

Specifications

The HB-10 is a MSX1 with a Z80A from NEC (DA780C-1) or Sharp (LH0080A).

The non-Japanese versions have an MSX-Engine from Yamaha (S3527). The used VDP outside Japan is the Toshiba T6950, which does not support some undocumented features of the Texas Instruments TMS9918, TMS9928 and TMS9929 VDP's.

Quirk on port A8h

The models HB-10B, HB-10D and HB-10P and some very early versions of the HB-20P have a quirk on port A8h that makes RAM Page 3 appear both in slot 0 and in slot 3. This mirroring effect is emulated in openMSX for the Sony HB-10P, it can be very annoying as it can play havoc with games that need more than 16kB RAM, using the 16kB RAM mirror to store system variables and assuming that all the ram is in the same slot 0 as page 3.

This configuration can cause poorly written software to crash. Nevertheless, you can run these games if you type following command before loading:

OUT &hA8,240

For cartridges, the trick is to plug it after booting using a slot expander that has switches to disable each slot and prevent them from auto booting (WARNING!! Do not insert a cartridge when power is ON. It can damage the machine). Then type the following instructions on BASIC after re-enabling the slot:

OUT&hA8,240: DEFUSR=&H7D75: ?USR(0)

Alternatively, you can use ROM loaders like Execrom, LoadROM or OPFX /X. Since they start the game from MSX-DOS, this problem will be automatically solved as DOS already selects the proper slots for the RAM.
