#Cpu speed accelerator 6.2 serial serial#Working: mouse, zorro listing of detected cards, composite video out, video out, serial (out at least), one audio ch (the other one should work too), keyboard.īooting a workbench from the accelerator CF sorta work until noise issue or something make any disk I/O hang and crash. My first prototype have been tested with DiagROM v1.1. Then you can add ICs and run DiagROM and then enjoy.ĭO NOT POPULATE: J1, J2, C902, C917, R901, FB904, FB906, RP904, RP906, RP905, C230, C240, they are unpopulated on factory 6.2 rev, so, let them as-is. Solder everything else, don't populate ICs yet, re-power and re-test. Then solder all the electrolytics caps, connect power, re-test all the lines. If building it for real: first test the PCB for short between GND and the various power lines (+5V, -5V, +12V, +5V_USER, etc.), the zorro should have all. Other chips (paula, denise, CIA, etc.) are got from a donor motherboard. The the table at the bottom of this README for a list of DigiKey and Mouser P/N for ZORRO, CoPro, Video and ISA slots. #Cpu speed accelerator 6.2 serial Pc#The ISA (8bit and 16bit connectors) fits perfectly a full-length connector got from like an old PC motherboard. Memory and RTC chip should be got from eBay, same for the PST reset thingy (U1). #Cpu speed accelerator 6.2 serial full#The file amiga2000.csv contains a full Mouser BOM, around ~150€. If using an A500-Flash from Retro 7-bit, U540 and U203 can't be socketted or they will be too high. So the five caps should be placed like this (IGNORE the + footprint on the PCB): The capacitors on the left of the POWER Connector are somewhat troubling if you don't have a lot of experience. ![]()
