I'm looking for an Integer BASIC ROM set for an Apple ][.
The Apple part numbers are:
E0 (part # 341-0001)
E8 (part #341-0002)
F0 (part #341-0003)
F8 (part #341-0003) - I might not need this...
Getting 2716s with Integer BASIC is no problem - I need the 2513
parts.
Basically, I'm "downgrading" an Apple ][ plus into an Apple ][.
I suspect I'll have to do a lot more to this machine, haven't take it
apart yet, but the power-on-reset circuit isn't engaging, and keyboard
reset doesn't help. The 555 chip at A13 appears to have red oxidation
on the pins - ie actual rust, Iron Oxide, not the black oxidation you
sometimes see on older chips.
Something may have spilled in the machine, or just really improper
storage... Naturally the 555 timer and 741 op-amp are the only two
chips without sockets on the board. When I build my Apple ][ clone,
I'll use two 558 (quad 555) timers and save a chip.
