A600 kickstart pinouts.

Smiley · 20 March 2007, 01:06

Can somebody please confirm that this is correct:

Pin 21 = +5v
Pin 10 = CS
Pin 30 = GND

here are some pinouts

27c210

this (and its larger memory brother 27c4xx) use a 40pin DIP with Vcc upon (pin40)

I currently I am using a 27cx400 (40P DIP UVEPROM) in my A600 with KS3.1*as is smiley*

I have helped Smiley design the following (based on some crazy russian shema from aminet)

heres the problem that has me some what confused..

these pinouts seem to be in contrivance to the datasheets I have

http://www.amiga-stuff.com/hardware/2mbit-maskrom.html

I cannot understand why, is the above not compatible with the A600 ? or do I have the wrong datasheets ?

Appreciate your help guys.

What pinouts do you have? The 27c400 pinout I have has VCC at pin 21. Are you looking at a pinout for a 27c240?

Edit: read your message again. The 27c400 and 27c210 do not have the same pinout.

Zetr0 I am 99% sure The Vcc is pin 21.

Have you got a multimeter to test with?

the DIP 27C4000 datasheet i can find is a 32pin format....

It would seem I have a lot of incorrect datasheets here....
