Re: Sony HBI-50
Hi Does anyone know what is this?: http://page.auctions.yahoo.co.jp/jp/auction/31169109 It is not listed in the MSX HW List. It seems a slot expander, but Im not sure (there are two slots for cartridges). I saw it too and included it in the hardwarelist. But I forgot to upload it. :) I think it's a slot expander indeed. I also used the translation and my interpretation is that "increase cartridge box" means "slot expander". :) Grtjs, Manuel PS: MSX 4 EVER! (Questions?

wd273 emulation.
I'm working in disk emulation via the wd2793 in mess. This will have far more authentic emulation. First of all I'm working on emulating the Philips diskrom, I've found the following: Write: 7FF8: wd2793 command register 7FF9: wd2793 track register 7FFA: wd2793 sector register 7FFB: wd2793 data register 7FFC: side select. bit 0 : 0 = side 0, 1 = side 1 7FFD: drive select. bit 1-0 = drive. bit 7 = "in use" led (led on if bit is set and right drive in bit 1-0). 7FFE: nothing 7FFF: nothing Read: 7FF8: wd2793 status register 7FF9: wd2793 track register 7FFA: wd2793 sector register 7FFB: wd2793 data register 7FFC: bits 7-1 set, bit 0 is last value written 7FFD: bits 6-2 set, bit 7,1,0 is last value written 7FFE: unused (0xff) 7FFF: bits 5-0 set, bit 7 set if data request, bit 6 reset if interrupt request Can someone verify the correctness of this? Also does anyone know if the Sony machines use the same layout? Cheers, Sean -- For info, see http://www.stack.nl/~wynke/MSX/listinfo.html

Also does anyone know if the Sony machines use the same layout? There is a small difference in the way Philips and Sony machines handle the in-use led. The Sony machines disregard the bit used by the Philips machines to control the led. So the Sony drive led is on when drive select matches the drive. The Sony disk ROM selects drive 3 at any time when there is no disk activity to turn off the drive led. Bye, Maarten -- For info, see http://www.stack.nl/~wynke/MSX/listinfo.html

MSX2 in Brazil
Hi I was wondering if MSX2 computers were sold in Brazil (I mean that if they were distributed to shops by big companies like Sony, Sanyo, Philips, ...). Ive read that two companies (Gradiente and Expert) sold MSX1s. I also was wondering if other companies sold MSX1s in Brazil. Greets -- For info, see http://www.stack.nl/~wynke/MSX/listinfo.html

I´ve read that two companies (Gradiente and Expert) sold MSX1s. I also was wondering if other companies sold MSX1s in Brazil. The companies are Gradiente and Sharp, and the respectives MSXs were called Expert and HotBit. All MSX2 produced in Brazil were transformations over the original MSX1s made in Brazil. Unfortunatelly, Gradiente and Sharp had never made an original MSX2 from factory, so our only choice was to install adaptation boards originally created by Ademir Carchano for exchanging the VDP, add SUBROM in the appropriated slot and the necessary VRAM (always 128kb). Some years later an adaptation board was designed for transforming Experts and HotBits into MSX2+.

Re: wd273 emulation.
Hi, In Sony machines and in NMS8245, some wd2793 registers (track, sector) are write only. In first version of fastcopy I mantained track number and sector number by just looking at the registers. This version did not work on Sony or NMS8245. Later, I corrected by maintaining track number and sector number in variables in the program and write them to the registers whenever needed. For the rest: 7FFD is a little bit more subtile: bit 1,0 : drive number bit 7: motor on/off (and not simply 'in use' led) Following bit table is applicable for the two drive number bits: B1 B0 0 0 : drive A selected 1 0 : drive A selected 0 1 : drive B selected 1 1 : no drive selected And 7FFF is also wired (at least in Philips, I'm not sure anymore about Sony): bit 6: !INTRQ bit 7: !DTRQ I do not see a direct practicle usage for reading out the INTRQ and DTRQ signals of the wd2793 controller. But applications may exists that do rely on them so a perfect emulation should emulate these bits as well. But I think that in reality 99.999% of MSX software will work if you do not emulate them.
