Help with battery bombed IIgs

Submitted by fritter7 on December 8, 2025 - 2:25pm

I think I've bitten off more than I can chew. :) So I got my first two retro machines at VCF Midwest in September, and the SE was super easy. Just needed to replace the battery holder, added a few mods - fun! But I also got a battery bombed IIgs that I'm definitely not experienced enough to figure out what's going on. I've attached a pic of the area that was bombed - it's been cleaned up a bit since then.

Rana EliteOne Drive repair

Submitted by dayoff on December 8, 2025 - 10:16am

Hello!  I was wondering if anyone was familiar with any sources of information on repairing Rana drives?  I have a Rana Systems EliteOne on me IIe that just powers up and spins continuously.  I'd like to get it going but was surprised to see some manuals out there, but not a lot of people digging into this model, unless I'm just poking around the wrong places..

 

Thanks!

Pete

Smartport disk emulators and daisy-chaining

Submitted by colinleroy on December 4, 2025 - 11:39am

Hi,

In the last weeks I wanted to add a smartport "hard disk" to my Apple IIc setup, and chose a SPIISD for that. First I had a problem with it: it is not seen when booting from the internal floppy drive. Basically it's because it boots too slow and missed the smartport RESET/ENABLE sequence that is used for device ID assignment.

I fixed that in software.

Apple //e: DuoDisk Format Track $00 Errror (both drives)

Submitted by atomicham on November 24, 2025 - 1:46pm

I have an Apple //e with a DuoDisk Card and Drive Unit. I haven't used it in many years, preferring modern solid state; however, I wanted to get the drive going again. I tested it as-is and found speed issues. I performed maintenace to clean the heads, correct the speed, clean up, etc. Drives are operating as they should (speed check, etc.).
