This is a modified/updated version of Mike Willegal's Brain Boards for Apple II. For those unfamiliar with them, it's a slot card which can be used for things like running integer basic or the Wozaniam pack (which mimics Apple-1 including BASIC and cassette interface). As such this is a great way to functionally build your own integer basic ROM card, with added Apple-1 "Wozaniam" mode.THIS RUN IS ON BLACK / ENIG PCB's. Purple was used for the initial batch, and is seen in the supplementary LISTING IS FOR PCB and full parts KIT. You must solder it, it is all through hole. I do not have any assembled units at this time.
Some Apple 1 software can be loaded right to the Apple II cassette interface. Not all Apple 1 programs will work with Mike Willegal's Wozaniam pack, but I have tested specifically the Apple 30th Anniversary machine code, as well as some programs like blackjack and buzzword which require BASIC at E000, and they work as expected.
The update to this version was done originally by Macnoyd who provided the ROM code for this version. I put the revisions into the PCB design; This version uses the previously unused DIP2 to toggle between the upper and lower ROM regions. The result is a Brain Board which can have Integer, Applesoft, and Apple 1 (wozaniam) modes depending on DIP configuration.
This is an open source project under GPL and as such you are more than free to fabricate or even sell these yourself :) The ROM is shared with permission of Macnoyd, who I am most grateful to. If you would like to download the gerber files, Osmond file, Concatenated ROM, or just read more about this, please see my github project which includes your is included and preprogrammed with my new QuickStart ROM, which can give you both Apple 1 and integer basic modes without losing your system ROM.
These work in Apple II and II+ normally, and IIe as well. The only thing for a IIe, since it lacks back slot openings like the previous cases, is I recommend taking a 5 pin section of right angle header, extracting pins 2 and 4, and soldering that in place of the toggle switch. Then you can wire any remote on/on SPDT of your choosing.
The original documentation for the card can be found on Mike Willegal's site: style="color: rgb(35, 31, 32); font-family: Helvetica, Arial, sans-serif; font-size: 14px; background-color: rgb(249, 249, 249);">
Normal operation is the same if you follow the quick start guide from the original Brain Board manual.
DIPS:
1,3,5,8: ON
4,6,7 OFF
To bypass your system roms, burn the other ROM from the repository with applesoft and integer, and change DIPS to the following configuration:
1,4,5,7 ON
3,5,6 OFF
2 - FP/INTEGER
If you do not need Apple II Integer basic, the first config is most compatible with other expansion cards and accessories. The second config makes the brain board more versatile in having 4 user roms instead of 2, but may cause conflict with some expansion cards since you lose access to the logic boards own ROMS that way.
