Warning ! This page contains a build log, and therefor schematics and layouts which aren't tested or which contain errors. DO NOT attempt to build anything described here.
Schematics for review, please post comments/suggestions/fixes with signature.
Both boards sent to fab --Furrtek 23:43, 6 August 2012 (CEST)
Boards received, will start tests the 9th --Furrtek 01:22, 4 September 2012 (CEST)
According to documentation, MAX II isn't 5v tolerant. --Hpman 15:40, 5 September 2012 (CEST)
True, will do basic durability tests. If they fail, I'll add level translators as suggested. --Furrtek 02:28, 7 September 2012 (CEST)
Errors on first prototype:
- 4MB/ROMOE swapped because of part-footprint link wasn't updated.
- 245s in the wrong direction (AB/BA), added an ALS04 inverter on direction pins to fix.
- Cut /ROMOEL to AND (wasn't going low ?), connected /ROMOE instead.
- Missing connections for LOAD, H and EVEN to the CPLD, added jumper wires to pins 48, 49 and 50 respectively.
- Zoom problems, will try adding the RC delay on EVEN.
Puzzled works, KOF95 seems to work with some bad colors (maybe bad palette ram), Metal Slug 2 resets at the title screen.
