MicroDrive Problem

Submitted by Gumdoc on October 5, 2021 - 12:24am

Hi All,

 

This one driving me a bit crazy. I have the GS version of the MicroDrive Turbo. I have 4 volumes on there, 3 that came with the card, one I created. The first is PRODOS and utilities, the 2nd is a GS/OS volume, 3rd is Total Replay, and the 4th I've created both a GS/OS 6.01 and 6.04 volume.

GS/OS

Submitted by Gumdoc on October 4, 2021 - 6:18pm

Silly question, why does my GS/OS show two 5.25" drives on the desktop? I don't have any physical drives connected other than the 3.5" one, does it have something to do with the daisy chain on the back of the 3.5" drive?

3.5" Drive question

Submitted by Gumdoc on October 4, 2021 - 1:30pm

I just obtained a nice IIGS system which included the A9M0106 drive. The system also included around a dozen 3.5" disks that the seller created...but these are all on DS/HD disks. Can I even use these disks? I thought the A9M0106 was an 800k drive that would only work with DD disks.

Thanks for any help.

repair or replace ALPS key switch

Submitted by dfxgordon on October 3, 2021 - 9:59am

The right arrow key on my //e finally became unusable.  It appears this is a long stem ALPS switch.  Taking it apart and digging online I find the way it works is when the plunger goes down, the pressure is redirected horizontally by a "leaf spring" which presses against a switch plate.  There is a tiny dimple in the center of the leaf spring which I suppose enhances the pressure.  Experimenting with an ohm-meter shows that the switch plate works fine if I remove the leaf spring and apply the pressure directly with a small screwdriver.  So I wondered if it might be worth trying to reshape t

"Vaporlock" technique from Don Lancaster's Enhancing Your Apple II and IIe

Submitted by PraetorX on October 1, 2021 - 3:00pm

I was reading about Don Lancaster's "Vaporlock" technique for finding the exact timing of the vertical blank during screen refreshes.   Does anyone happen to have the sourcecode available or know where I can find the companion disk that came with Enhancing Your Apple II and IIe?  I am hoping to avoid typing everything in manually

The Ultimate Apple II Accelerator - The MCL65-Fast

Submitted by MicroCoreLabs on September 29, 2021 - 5:35pm

I just uploaded a short demo which replaces the 6502 emulation of the MCL65+ with the ability to run compiled C code. I adapted a printf, scanf, and a few functions to allow access to the video memory and the keyboard which makes it easy to run regular C code on a vintage computer via the 6502's bus interface.

Apple ][e strange composite behaviour (PAL AFAIK)

Submitted by Ronin47 on September 29, 2021 - 9:15am

 I'm looking at ways to improve the composite signal from my ][e, because the composite video output is really poor quality.  I did read this  Thread on composite  however it didn't really enlighten me.What is interesting is that the Apple only seems to work with my Dell monitor, which has a composite input.

FloppyEmu Question

Submitted by Gumdoc on September 28, 2021 - 6:15pm

Anyone familiar with the boot process for the FE? I am using the card that came with the system but also tried to copy everything to a 32 GB FAT32 card. I have no issue booting a 3.5" or a 5.25" image, but when I set it to SmartPort mode and turn the machine back on, nothing happens. I looked inside the SMART0.po image, seems to have ProDOS and a bunch of other utilities. Clearly I must be missing a step, any ideas?

 

Thanks for any help.

//c Serial to Parallel Converter

Submitted by nick3092 on September 27, 2021 - 11:13pm

I have a //c serial to parallel/centronics converter box from when I was a kid.  I still have the matching parallel printer, but sadly it doesn't look like the ribbons are available any more.  I have since acquired an ImageWriter II (which does have ribbons available), so I don't need to use this.  But I recently picked up some Epson FX compatible Commodore printers that have both the Commodore serial and centronics ports on them (and have ribbons available).  I was thinking about testing out printing from my //c to one of them.
