Hard drive for the Apple II

Submitted by wment on January 15, 2020 - 3:32pm

I have a Corona Starfire 5 hard drive for the Apple II that has been in a dusty closet for over 20yrs. The other day I plugged it in to a IIe and to my suprize it booted. It appears all of the 33 partitions are readable. Wow... Who would have thought. I have a short video that is too big to up load here so I put it on Youtube. If you search for Corona Starfire you might find it.

 

If anyone has any docs or the origional s/w for this please let me know.

Duodisk analog board troubleshooting

Submitted by joel_graff on January 14, 2020 - 4:14pm

I'm trying to troubleshoot the analog board on a DuoDisk unit.  It's a 676-[]102.  Specifically, of of the two main jumpers (J3 and J4), J4 appears to be dead.  That is both disk drives spin when connected to J3, but neither do on J4, additionally, the LED is constant on for the J3 side, but not at all for the J4 side.

Leisure Suit Larry

Submitted by Spottedfeather on January 13, 2020 - 6:16pm

For the life of me, I can't find Leisure Suit Larry roms anywhere. At least, not ones that work. I've found some, and it will start, but when I hit a key to start the game, it just goes black.

Troubleshooting the II+ cassette interface

Submitted by Fuji on January 13, 2020 - 11:50am

UPDATE 2: ... and now I've gotten the 16K RAM card to work as well! Things are apparently moving forward quickly today!

Could be reseating some ICs, the IDC cable, the card itself in the slot or something else.. In any case it appears to work now and I've even gotten ADTpro to transfer with ProDOS, so that's one HUGE leap forward! I am however confused about some details regarding ADTpro, but think I'll post about that separately.

 

UPDATE 1: I just discovered that the cassette IN actually works! (after posting my message below).

Apple III video issues

Submitted by nicko6113 on January 12, 2020 - 6:51pm

hello i just joined this forum in hopes to get my apple III working again.

 

i have what i believe to be the mem diag screen. however it takes up the entire screen and is mostly random garbage. 

however if i remove the ram board completely i get a solid white screen.

 

i have tried reseating all the chips on the motherboard. and i swapped around ram chips to see if i could atleast get it to display a normal mem test. nothing i did changed it.

the on light on the keyboard is also working.

 

does anyone know where i should start looking?

Maybe it’s a clone?

Submitted by Fuzzyman on January 12, 2020 - 5:34pm

I was on the hunt for old keyboards and a guy in my area was selling off all the parts from his former computer repair business. One picture showed a bit of what appeared to be 70's vintage in a very large case. They were Honeywell Hall effect switches (cool!) but I opened up the case and there was some kind of motherboard in there. He asked for $10 and I walked away happy.

Apple II plus diagnostics card / ROMs

Submitted by CheshireNoir on January 7, 2020 - 6:35pm

Hi again,

So I'm still trying to get my EuroPlus working reliably. It's getting there, but I'm having a hard time tracking down some faults. 

(I've bypassed the PAL card for now, and I have a spare coming in a few weeks that'll help me isolate that part donw)

For most other systems I've worked with, there's usually a diagnostics card / cart / ROMset available. I know the later models had diagnostics built in, but this is only a Plus.

Need Help With Apple IIGS Memory Error

Submitted by Ahow77 on December 31, 2019 - 4:44pm

I have a rom 1 IIGS with a 4mb expansion card and I'm trying to get a music program called Sonix to work with it. I'm using Floppy Emu rev B to load the image. I get past the initial ProDos 8 title screen then it shows this memory error:

"Allocate 0101
***MEMORY ERROR***
Must be user #1
De-allocate all managed memory "

Then it gives me a command prompt and I don't know how to proceed. Any help would be appreciated.
