Declaring interest.(Interest withdrawn here)

The current a1kboard_00.zip found at Georg's site contains the IC53_01_15ns.jed (dated 09/09/2012) logic file. Probably, updated for the v4 board. Mike

That works for me too! ;) ---------- Post added at 01:16 ---------- Previous post was at 00:25 ---------- Looking at past GBA1000 builds K6R4008C1D-JC10 (+5.0V) fast memory chips were used quite a few times. Nothing has changed in this 4th version of the board that would require less...

@yamakakiche I have the same chips, and glad to hear that they are working. The only concern I have is that if the voltage being received is at the high end of the maximum or above that it will cause a failure at some point. Can you get a Multimeter reading of the voltage on pins 9 and 27 of...

Reading the data sheet on the CY7C1049CV33 the Supply Voltage VCC limit is -0.5 V to +4.6 VDC. Never want to operate at the upper maximum for any device as it will fail sooner than later. So, it is not looking very encouraging. Someone with a bit more schematic and voltage knowledge would...

I received my CY7C1049CV33-15VXC from Kipper2K. I have not installed them yet, but many of us have them. Below is the definitions for the codes on the chips that I have. You can find them in the datasheets. Ordering Code Definitions: CY - 7 - C -1 - 04 - 9 - C - V33 - XX - XX - X - X CY...

Damn, purchased what was supposed to be a non-working, broken, damaged, about to be thrown in the trash Amiga 500 only to find out today that it works just fine. I was about ready to take it a part to begin my component mining operations, but for grinds and giggles I decided to power it up, and...

I have been working on a spreadsheet that takes the Partlist from the schematic and details the component sources such as Digi-Key, Mouser, Jameco, or donor boards like A500, A1000, and A3000. Each component is hyper linked to the suppliers website for ordering or a donor board (orientation)...

Very nice work Massimo!!!!:thumbsup:

When will this next batch (#4) be completed and shipped? Thanks, Mike
