16KB RAM expansion for the Apple II+ fpga port

I’ve added a 16KB RAM expansion to the MiST port of the Apple II+. It’s seen as a language card in slot 0.

I’m also working on a Saturn 128KB RAM expansion but it’s not working yet and need some more work.
To implement both I made use of some manuals available on the net which show the control codes for those cards which need to be implemented in the hardware.

See: LANGCARDMAN.pdf Appendix D page 25
and: Saturn Systems 64K and 128K RAM Board – Operations Manual.pdf Chapter 9 page 68

Binaries are now on the MiST github repository: https://github.com/mist-devel/mist-binaries

vic20 update

I’ve uploaded a new binary with 8kb more RAM (28kb in total) and cartridge multipart support.

To run multipart crt’s turn on “CRT with load address:yes” and load the lower part first.
Use the Tosec crt’s without the “[a]” in the name because we need the load address. Load the $4000 or $6000 part first and then the $A000 part. The $A000 crt will trigger a reset and starts the game.

Astrocade update

I fixed the scanlines for vga output. Since its done in the scandoubler its vga only.
RGB output is working fine (mist.ini, tested with my new cable I got from Till).
Also the keys are remapped:

  -- Astrocade      maps to pc key
  -- 0..9           0..9
  -- x              keypad x
  -- -              keypad -
  -- +              keypad +
  -- =              keypad enter
  -- .              keypad . or ,
  -- c              c
  -- v              v
  -- ce             delete
  -- mr             x
  -- ms             s
  -- ch             w
  -- ^              a
  -- %              p

-- Astrocade maps to pc key

-- 0..9 0..9

-- x keypad x

-- - keypad -

-- + keypad +

-- = keypad enter

-- . keypad . or ,

-- c c

-- v v

-- ce delete

-- mr x

-- ms s

-- ch w

-- ^ a

-- % p

The binary and source can be found at the usual places.

Bally Astrocade console for the MiST FPGA

I’ve ported another classic console to the MiST resurrected by MikeJ from www.fpgaarcade.com: The Bally Astrocade.

There’re still some todo’s left as I didn’t got the joystick working yet and I’m thinking of redo the key mapping. The current key mapping:

  -- bit  console           maps to pc key
  --
  -- 0    c   ^   v  %      z  a  q  1
  -- 1    mr  ms  ch /      x  s  w  2
  -- 2    7   8   9  x      c  d  e  3
  -- 3    4   5   6  -      v  f  r  4
  -- 4    1   2   3  +      b  g  t  5
  -- 5    ce  0   .  =      n  h  y  6

Player 1
- Arrow keys and space for fire
Player 2
- Numkeys and Num0 for fire

-- bit console maps to pc key

-- 0 c ^ v % z a q 1

-- 1 mr ms ch / x s w 2

-- 2 7 8 9 x c d e 3

-- 3 4 5 6 - v f r 4

-- 4 1 2 3 + b g t 5

-- 5 ce 0 . = n h y 6

Player 1

- Arrow keys and space for fire

Player 2

- Numkeys and Num0 for fire
