I'm trying to prepare an Apple // europlus for a small local no-profit museum so visitors can use it.
I am familiar with Apple //e and I am a bit lost here.
I understand the original Apple 2 did not auto-start so you had to type PR#6 to boot from floppy. However, ROM F8 is 341-0020-00 which I understand it should be the auto-boot one.
The other ROMS are
(D0 is unreadable from the pic I have)
If I power up with a floppy controller in slot 6 and drive connected (which I don't know if it works) I have "Apple ][" displayed. If I hit "RESET" it takes me to Monitor. I tried CTRL-C, CTRL-B, CTRL-P and 6 and nothing works. The only key which works is RESET.
Without the floppy controller, the Apple beeps twice and drops me to monitor straight away.
I see that 1 RAM chip at row E is missing and I understand that one might connect a language card there with a memory expansion. But I don't have a language card with this system.
What I have is pictured below, plus the controller card. I haven't tested the board with the VS1000 on it as it has tantalum on the 12V line and I'd rather replace them before I use it.
I've re-seated and contact-cleaned all the RAM and ROM but nothing changes.
I don't know whether I am doing something wrong or maybe there is something wrong with the system.
Someone recommended I checked the ROM are still correct but I understand they cannot be read directly with my TL866II? A link online suggests I can just use an inverter to make them (2316B) compatible with something the TL866II can read (2716).
Can someone help me? And is an inverter and some re-wiring really required to just read those ROMs with the TL866II? It feels weird.
Also, what would be the best way to replace those ROMs if needed? Is there a modern rewritable IC available? Does it have to be something which requires 21V programming?
Thanks for your help!
