Brain Board II build - EPROM help

Submitted by Stargeezer on September 18, 2025 - 11:10pm

Hello friends:

I am in the process of building a Brain Board II. I have everything assembled, but I am confused about how to program the EPROM.  I have read Mike's manual from the original Brain Board, but I don't quite understand the table about programming the board.  I have 27c128's and 27c256's available. 

Are the values in the columns offsets for each rom file? In other words, when setting up the programmer, do I put the D000 rom at offet 0x1000, rom D800 at offset 0x1800, etc?

Any pointers are most appreciated.

Cheers,

New ROM 4X System ROM for the Apple //c and ROMXc

Submitted by jeffmazur on September 18, 2025 - 1:11pm

Thanks to MG, there will be a new version on the ROM 4X coming out soon that provides additional support for both the ROMXc and the Xdrive2c. And it will automatically detect if one or both of these devices is present and provide the appropriate commands. Although the Xdrive2c is still in beta testing, anyone with a ROMXc can test the new ROM image from this disk.The only difference you should see is the new "8" command which will now take you directly to the ROMXc menu.

Merlin32 and DOS3.3 binary header

Submitted by loderunner on September 16, 2025 - 1:51pm

Hello all,

    I am trying to set up a simply development environment on my Mac to learn 6502 assembly on Apple II, it's got the following components

  • Emulator: Mariani (AppleWin Mac port)
  • Editor: VS Code
  • Assembler: Merlin32
  • Disk Image handling: CiderPress2

Basically the workflow is

1. assemble the source using Merlin32

2. using CiderPress2 to import the produced binary into disk image (.po, .do) file 

3. using CiderPress2 to set proper attributes (BINARY, AUX)

4. reboot Mariani.

Anyone have experience with using this drive? Does it work pretty well in an Apple II?

Apple II+ keycap parametric model

Submitted by profdc9 on September 14, 2025 - 10:02pm

Hello,

I have an Apple II+ that I can't get a keycap for, and I got tired of seeing it without it, so I designed a 3-D part.

It is a parametric model made in FreeCAD with adjustable dimensions so the size can be varied for the other keys.

The text for the key is embossed on the top of the key, and the key text can be changed by changing the appropriate ShapeText object.

Submitted by Kubbie on September 13, 2025 - 5:01pm

Sorry for the noobie question but I'm trying everything poissble that I can think of o try and get my IIGS working  with the RamFast SCSI Card. My LacIE external hdd failed as the SCSI card won't reconginize it.I found an internal 50-pin SCSI drive but I'm unsure what cables to use so I can attach it as the ribbon cable connected it to the SCSI card that goes out to a 25-pin scsi header for attaching external drives in back of the IIGS.

Help identify make/model of this 80 col card

Submitted by Kubbie on September 13, 2025 - 9:03am
Can someone tell me the maker of this 80 column card? When I boot up my Apple IIE the screen is all jumbled and jumping around. I’m trying to figure out the intention of the card as which way it should face in the J0 slot. I tried changing it to different orientations since the slot is not keyed but it comes up to the Apple ][E prompt right away so I think think it’s facing in the right direction. Tia fir the help

Submitted by Kubbie on September 11, 2025 - 10:45am

I'm trying to figure out differences between these 2 revisions as I'm unable to find much info on RevB. I knoe RevC has USB port and RevB used the IDE. Can RevB mount 8 paritions at the same times so I can run "What is the Apple IIGS"?
