New Modular Firmware BETA:
Requires use of the new firmware data preloader to erase the flash contents and install the new font data.
Separate builds for LC and WiFi hardware, VGA and Z80 functions.
Faster booting thanks to delayed loading of VGA rendering code and data (improves system type autodetection).
Supports changing fonts using $C0nB register. $00-$1F are duplicates of the defaults included with the ROMXce character generator. $20-$23 are defaults for Apple II, IIE, IIGS and Pravetz systems (please see the notes below about compatibility) $24-$27 are custom font slots. $24 is a simple Bold style font.
Monochrome modes are now supported with the $C0n1 - $C0n3 registers. $C0n2 and $C0n3 act like the II GS TBCOLOR and BORDER registers when $C0n1 is set to $Fx. $8x - $Ex select Monochrome output and palette. $00 will reset to full color mode.
The ∀2 Analog is a VGA Video card for Apple II, II+, and IIe computers.
The ∀2 Analog builds on the AppleII-VGA by Mark Aikens, adding the ∀2 PicoPal to condense the slot selection logic typically needed for Apple II peripherals down to one chip. The firmware of the ∀2 Analog has been expanded to support Apple IIe compatible DGR, DHGR, and 80 column video, as well as Apple IIgs compatible registers for Text, Background and Border colors. Multiple alternate firmware modes including a PCPI Applicard emulator, and more features are still being added.
The -LC and DIY SKUs have been retired, but will continue to be supported with firmware updates for the foreseeable future. Projects are underway to produce easier to assemble PCBs for DIY builders.
All new orders through the Tindie store will be fulfilled with the Fully Assembled ∀2 Analog w/ WiFi (Pico-W) SKU.
Every order now ships with ProDOS formatted floppy disks (3.5" and 5.25") with useful utilities for configuring the card, uploading fonts, and transferring data to/from your Apple II. New disk images will soon be available with updated utilities to match the modular firmware.
The hardware has been tested with Apple II+ and IIe (Enhanced) systems.
Compatibility with 3rd party addons is not guaranteed. Some addons may interfere with the system type autodetection. Some accelerators may cause problems when installed along side the ∀2 Analog cards.
Partial compatibility with Apple II GS systems. The ∀2 Analog Rev1 hardware does not have access to the M2B0 or M2SEL signals on the bus to qualify 16/24 bit addresses. This means any accesses outside the shadow memory banks will probably cause visible glitches in VGA output and may cause the card to incorrectly interpret memory accesses as soft-switch or register manipulation.
More testing is needed for compatibility with CFFA3000 and ROMX/ROMXe hardware. Check back later for updates.
