Notes about Disk System
|

- Ports 44 to 47 are for standard connection to FD2793.
|
||||
- Port 48 is used for drive/side/density select on write, and intrq/drq on read.
|
||||
intrq and drq are OR'd together, then gated to bit 7 of the data bus whenever
|
||||
port 48 is activated on read. There are no interrupts used.

|

Tests of old keyboard. Start mbeeic.
|
||||
1. Load ASTEROIDS PLUS, stay in attract mode, hold down spacebar,
|
||||
it should only fire bullets. If it sometimes starts turning,
|
||||
thrusting or using the shield, then there is a problem.
|
||||
|
||||
2. Load SCAVENGER and make sure it doesn't go to the next level
|
||||
until you find the Exit.
|
||||
|
||||
3. At the Basic prompt, type in EDASM press enter. At the memory size
|
||||
prompt press enter. Now, make sure the keyboard works properly.

TODO/not working:
|
||||
|
||||
- Printer needs to be understood and fixed.
|
||||
- Keyboard loses characters if you type at a normal rate.
|
||||
- Fix Paste (it loses most of the characters)
|
||||
|
||||
- 256tc: Paste ignores shift key
|
||||
- All others: Paste drops most characters, shift operates randomly.
|
||||
|
||||
- various fdc issues:
|
||||
- B drive doesn't work.
|
||||
- some disks cause MESS to freeze.
|
||||
- ENMF pin missing from wd_fdc.
|
||||
- incorrect timing for track register causes 256tc failure to boot a disk.
|
||||
- 56k model takes about 2 minutes to boot a disk if loaded via command line.
|
||||
|
||||
- 56k model takes 120 seconds to boot a disk if loaded via command line.
|
||||
|
||||
- mbeeppc, mbee128p: In Basic, keyboard loses characters. Works fine in Wordbee.
|
||||
|
||||
- 256tc: At the menu, if F2 pressed to activate the Monitor, the emulated machine
|
||||
crashes due to a bug in z80pio emulation.
|
||||
|
||||
|
||||
- 256tc: Keyboard ROM U60 needs to be dumped.
|
||||
- 128k: GOLD PAL needs to be dumped for the bankswitching.

- 64k: RED PAL needs to be dumped for the bankswitching.

Tests of keyboard. Start mbeeic.
|
||||
|
||||
1. Load ASTEROIDS PLUS, stay in attract mode, hold down spacebar,
|
||||
it should only fire bullets. If it sometimes starts turning,
|
||||
thrusting or using the shield, then there is a problem.
|
||||
|
||||
2. Load SCAVENGER and make sure it doesn't go to the next level
|
||||
until you find the Exit.
|
||||
|
||||
3. At the Basic prompt, type in EDASM press enter. At the memory size
|
||||
prompt press enter. Now, make sure the keyboard works properly.
|
||||
|
||||
|
||||
|
||||
TODO:
|
||||
|
||||
1. mbeeppc keyboard response is quite slow. You need to hold each
|
||||
key until it responds. It works much better if you overclock the cpu.
