I recently bought an apple iie, used. I also bought an enhancement kit from Reactive Micro. The enhancement didn't work like I expected it to. Here is what happened:
I received the kit and did the install. I booted the machine and saw Apple //e, which was great. I then did the self test (CTRL-Closed Apple-Reset). It went to a crazy screen with different kinds of boxes all over it. It did some changes to the screen for 20-30 seconds and then said: System OK. I took this to be success.I rebooted, hit CTRL-RESET to get the ] basic prompt, typed in an obligatory basic program (hello, will; for infinity), ran it successfully and pressed CTRL-C when I got bored. Then I typed, call -151, to enter the monitor and then:
*300: A9 33 00
which displayed my code:
0300- A9 33 LDA #$33
0302- 00 BRK
...then, I tried executing the code:
Unexpectedly, it buzzed my floppy drive and continued seeking on the drive (no floppy in the drive)what should have happened, at least according to me, was, it should have displayed:
0304- A=33 X=FF Y=FF P=30 S=F0
and stopped*showing that the accumulator had been loaded with 33 hex (what my machine code told it to do).This works fine in the Virtual ][ emulator w/the enhanced iie and it worked fine with the unenhanced iie that I upgraded.
I replaced the original video rom and the problem persisted until I replaced both the CD and EF roms with the originals. It works fine with the new 65c02 chip, but not the ROMs. I talked with the Reactive folks and they sent me a second kit, but the result is the same with the new chips.
Help :). This should work as I've described, shouldn't it? If you have any thoughts on what might be at issue here, I'd appreciate it. I've done it several times and each time with the same result. I'm attaching a pic of the system and the identification from the board.
Thanks for any assistance you can provide.
