I think we’ve seen Maderia .. 🙂
I bought a little notebook while being there.
I wrote about 12 pages of ideas, schematics and projects to start.
- Rewrite Wozmon to use my composite pcb (Atmega328)
access though via - Building a 68000 pcb with a minimal machine code monitor.
Using a atf22v10 as address decoder.
(Same as my 6502 , I love those devices)
Maybe I’ll add a micro sdcard reader - Add a lcd matrix display to my 8088/8086
- Creating a PLA alternative for C64 using ath22v10 (again)
- Make backplanes for my 6502, so I can plug cards with different POC cards.
Clockcard, Latched bus leds, multiple VIA’s, IRQ controller, SID + Buzzer (Maybe also AY-3-8910, see other posts), LCD, composite, serial, Matrix and serial_usb) keyboard) - IRQ controller because I have some devices without opendrain, so I can’t tie all IRQ’s together
- Amiga Chip Mem mod for rev 5 (using a ‘new’ 8372A)
- 8085 Cartridge new approach
- C64Pico fix and add backplane + breadboard version for POCs
- … more
8085 Cartridge revisited
Problem with cartridge: prg is 17k, exomized 10k.
So you need 2 banks of 8k.
This disables basic rom, needed for the program.
The program needs to be relocated to 0x800 anyway.
So my exomizer options will take care of that.
But the basic is not being enabled again.
exomizer sfx sys -o data.exo -Di_ram_enter=\$37 -Di_ram_during=\$34 -f'LDA #$37 STA $01' 8085.prg xa frame.asm -o frame.bin x64 -cart16 frame.bin
Result … JAM
