Or at least have some decent horizontal scrolling. 
Yeah, I think if they would’ve introduced just that single feature in the V9938 in stead of the V9958, our games would look a lot different.
Nostalgia Section (I liked Piter Punk's idea)
When I was a kid, I "had" a "Gradiente Expert DDPlus" (borrowed from my cousin) and my father had a "Sharp Hotbit" at work (it controlled a huge electronic panel - using small light bulbs - that showed 24 8x8 redefined characters with transition animations). After some time my father bought me a PC and I returned the DDPlus. Both MSX got lost in time. 18 years later, I bought my first MSX, a Panasonic FS-A1WX, which I sold a couple months ago because I needed the money.
- Gradiente Expert DDPlus + Gradiente MBW-12 monochrome monitor (green phospor)
- Sharp Hotbit 1.2 + DMX disk drive interface 1.2 + DMX 3.5" 720kB disk drive.
- Panasonic FS-A1WX expanded to 256kB (and later 512kB)
Present Time Section
I have some MSX, but I have listed only the ones I use most and/or don't think I'll ever sell. Maybe I'll get a MSX2 and/or a 2+ to be on this list, but I'm not even saving for them right now.
- Panasonic FS-A1GT - Dream fullfilled
modded to 1MB RAM by l_oliveira - Toshiba HX-22 - MSX1 with Stereo PSG outputs, RGB output and RS232C port
- Gradiente Expert GPC1 - Fully socketed MSX1 with RGB output and keyboard to share with my other Expert
- Gradiente Expert GPC1 fitted with CIEL 2+ Turbo board - Fully discrete (no MSX-Engine, only 74LS chips) MSX2+ with turbo
Would be great to see dumps and internals of those!
PHC-77 is too hard to open and, as pointed by mars2000you, usbsecretbase already have the pics. But I can do the software dumps if you want.
I will try to take pictures and dumps of HB-T7.
Thanks a lot for all of this! PHC-77 ROM dumps would still be great 
If I get more information on that MSX-Write stuff, I'll let you know.
OK, good news, MSX Write is now supported by openMSX. Thanks to Rudolf Lechleitner for putting a hint in his 0.48 source code about the switch address and to BiFi for finding that and finding the other switch address.
In case you're interested, it's an ASCII16 mapper with 2 extra switch addresses: 0x6FFF and 0x7FFF.
So, PiterPunk, if you can get the software side dumping (I hope including the MSXMEM and ident.bas tool and keyboard test), I can make a configuration for this machine for openMSX
If it does, I'd like to get that dumped and the cartridge emulated with the font ROM included, of course
