As @Trash80toHP_Mini said, I'm pretty sure it was @360alaska who did that?
Ahh... *thanks* for that!Yeah it’s here...
Aren't these 'filters' = there are capacitors inside as well? I'm sure I was reading about these somewhere - but can't put my finger on it atm...I have ever seen resistor do before!
Yes they are, the ones used in the macs are 2x25R resistors in series with a 200pico cap to ground from the midpoint.Aren't these 'filters' = there are capacitors inside as well? I'm sure I was reading about these somewhere - but can't put my finger on it atm...
Well... these guys have them for only £1.589 ea... only 2000 minimum!although you can buy them new they are £5+ each
Oops... I blame Google... (and my failing vision)! £1.20ea for 2000... a snip!Those aren't quite the correct ones
Yep, there are two AM29F040's (or SST39SF040's) there is also a tiny 74HCT1G04GW above the right chip that inverts R/W to generate OEIs the ROM-Inator just comprised of those two SMD chips in the very center of the logic board?
SST39SF040's
Indeed, it's just fab!I'm logging in for the first time in a year, just to say that this is cool!
Sweet! Things are realy coming together. Welcome back, BMOW.There's a "Flash Tool" software program on my web site to support in-system reprogramming of the ROM disk.
