Great! I can't look them right away now, work issue, but I'll return to this subject later.

Well... not at least quite yet... I think it would require some hardware support as well...
If someone is interested, here is the shit I did to make it post:

cd /temp/knit
extb shit
debug set_watchpoint write_io 4 {} {carta PAGE[expr {[$::wp_last_value /16)&3}].ROM}
carta PAGE3.ROM
reset

Here is my shit.xml extension:

<?xml version="1.0" ?>

Is this just a "knitting-oriented" drawing tool ? If yes why all the huge hardware around (or is there a knitting device that can be plugged in) ??

Just two Roms and a slot for a memory (probably SRAM) card. This software seems support the HAL Laboratory Handy Scanner (inserted in another slot).

Perhaps the sram is used as SRAM-disk. That would justify the many components. Otherwise it is only to manage the mapping of the two ROMs and the SRAM.

After the titles screen, does the designing screen with mouse-controlled cursor show up? If so it's fine.
Conceptual diagram here The knitting machine SK-581 is not connected to the Knit Designer (KD2) or MSX real time, you have to remove the memory card from KD2 and insert it in another device U-BOX controlling the knitting machine.
When KD2 is running on a MSX a printer and a scanner interface (which is connected to a scanner) can be connected to the MSX but not directly to the KD2. KD2 works fine without them. KD2 actually boots without the memory card.
SK-581 and U-BOX are available at around 10000 and 6000 yen respectively. They work like this.
Forgot one thing: KD2 has no megaROM or MSX logo, neither on itself nor manual. One more: The memory card requires a button cell so it's probably a common backup SRAM.

It never ceases to amaze me the different applications the MSX was used for Big smile . Thank you Takamichi for letting us know about it. If someone wants to buy this rarity...

So, NYYRIKKI, can you describe how it works?

How large is the total ROM and what happens with these 4 I/O ports exactly?
