The Replica One looks like a cool project. But I'm a little disturbed
that he calls it a 'replica' considering:
(quotes from web page)
A new circuit layout was done on the replica 1 to implement a more
simple circuit and replace older no longer available ICs.
Simply add your own PC 386-Pentium class power supply, a composite TV or
monitor and a PS/2 keyboard or Apple II style ASCII keyboard and you are
set to go.
(end of quotes)
The Apple 1 didn't use an 'external power supply.' You hooked up your
own power transformer to it, it had the onboard power supply etched in
the board. It didn't work with a PS/2 keyboard (obviously), you
attached any available parallel strobing ASCII keyboard. There WAS no
'apple' keyboard- Apple Computer's sole 'proprietary' component in
the
Apple 1 was the circuit board stuffed with COTS chips.
And it doesn't use the original chips? My hope was that it was a true
'replica' and you could order it for Big Bucks with vintage silicon, or
order a bare etched and drilled circuit board and have the fun of
seeking out (or digging through your junkbox of spare chips) for the
chips.
My memory from the above details about about Apple 1 power supplies,
keyboard, etc. comes from what I remember of the review article of the
Apple 1 that was in issue 2 of Kilobaud. (the same issue with the
full-page display ad for the Apple 1 with $666 price and all). I never
owned one. (was lucky to be able to afford a programmable calculator in
that era)
Damn, I wish I hadn't sold off that complete set of Kilobaud a number of
years back....

Or just buy a Replica-1 Apple-1 replica. Vince Briel has been
wonderful in providing Replica-1's as give aways at the past few
VCF's. Please support him today by buying one!

I'll donate the wooden case. Do you think if we put a 'vintage'
keyboard in it (i.e. one without the 'windows' keys around the
spacebar) it will fool them??
(there's probably a 'trick' involving a PIC controller or something
to convert a PS/2-type keyboard into a parallel strobing keyboard
which would make it work with an Apple 1. However, both the PIC and
the keyboard controller on the keyboard itself would be more
powerful than the 6502 in the Apple 1) Maybe we need a contest giving away an Apple 1
;)
If someone's willing to donate one then sure!
