Ahoj,

zakladam toto vlakno pro sdileni zkusenosti se $subj. Chtel bych diskutovat poznatky/problemy/zkusenosti se stavbou/testovanim/provozem. Proste vse. co by pomohlo k jejich pouziti.
1) K pametovym kartam jsem zjistil
Memory Mapping Register
address R / W Description
B4h W
Bit 7 6 5 4 3 2 1 0
signal
MRSEL
Select the memory mapping register to be read and written in B5h
After reading / writing B5h, the value of B4h is autoincremented
MRSEL Memory address MRSEL Memory address
0 0000h - 1FFFh 4 8000h - 9FFFh
1 2000h - 3FFFh 5 A000h - BFFFh
2 4000h - 5FFFh 6 C000h - DFFFh
3 6000h - 7FFFh 7 E000h - FFFFh

Memory block number to allocate
MB Memory block Weight when accessing
00h - 0Fh Main RAM (8K × 16 = 128K) On M1 cycle + 1
10 h - 1 Fh Extended RAM (8 K × 16 = 128 K) On M1 cycle + 1
20 h - 27 h Standard graphic VRAM (B / R / G / I) +1 (*)
28 h - 2 Fh Extended graphic VRAM (B / R / G / I) +1 (*)
30 h - 31 h Standard graphic VRAM (Read Modify Write) +2 (*)
32 h - 33 h Extended graphic VRAM (Read Modify Write) +2 (*)
34h-37h IPL ROM On M1 cycle + 1
38h Text VRAM +1 (*)
39h Kanji ROM / PCG +2 (*)
3Ah Dictionary ROM ???
3 Ch-3 Fh Communication ROM On M1 cycle + 1
(*) M1 cycle impossible · When accessing during the display period, wait until the blanking period separately takes effect
According to the survey of the X1 center , the CPU accessible period of the graphic VRAM is 24 KHz: memory write cycle + 50 clock + memory write cycle 15 KHz: memory write cycle + 91 clock + memory write cycle Normal access · additional weight by the read modify write They are + 1 and + 2, respectively, but the above values do not change

Slo by tedy vyzkouset zapsat na MemoryBlock (cislo bloku), pak na MemorySelect (cislo banky) a zapsat par byte (ne pro ROM) a pak je stejnym zpusobem precist.
Vysledkem by mohlo byt zjisteni, ze to tak funguje a ze pridavne karty funguji. Nasledne otestovat, ze jsme vyrobili repliky dobre a ze funguji.

HSCRL
Horizontal scroll amount 0 to 7 in 1 dot unit
A specified number of white pixels are inserted from the left edge of the screen, and the screen shifts to the right by that amount (scrolls)
Therefore, it is necessary to hide the left end from the display area
In 320x200 2 screen mode and 256 color mode, this function can be used only for screens 0 and 2, so it is practically impossible to scroll smoothly

G / RB 0: DATA [3: 0] is written in the blue component of the pallet number PALNO, and DATA [7: 4] is written in the red component
1: Write DATA [3: 0] to the green component of the pallet number PALNO
The validity / invalidity of the pallet board is controlled by the OPO IOA [2]

A pak tady zapisovat do registru PALNO cislo barvy G a RB a pak jeji hodnotu

4) Mel by nekdo schema a/nebo fotky teto pridavne karty? Ze by se mohla casem pripravit a vyrobit replika. samozrejme by to chtelo mit v MZ-2500 ten pridavny domecek, ktery by se mohl taky replikovat.
MZ-1 R 37 640 K EMM16 bit I / O access required
address R / W Description
ACh W Write address latch
EMM address [19: 16] = {A15 - A8}, EMM address [15: 8] = {D7 - D0}
ADh R Reading data
EMM address [7: 0] = {A15 - A8}, data = {D7 - D0}
W Write data
EMM address [7: 0] = {A15 - A8}, data = {D7 - D0}
* There is no auto increment of the address

Tak to bylo pro definovani par takovych bodu, kterymi by jsme se mohli zabyvat a urceni mista, kde je sdilet.
