IIgs with flickering checkerboard boot issue...

Submitted by axel_m on March 25, 2022 - 1:05pm

Hi all,

I have a firends ROM3 IIgs here which refrains from booting properly. It goes straigt into a flickering checkerboard like so: https://youtu.be/bRoEhC-HIzo

Booting into self-test gives a more colored checkerboard with some random movements: https://youtu.be/Xb7L7TnC-GA

Initially I thought that might be a ROM issue, but after swapping the ROMs for known good ones as well as the CPU, it's clear that there's more to it.Do you, the nice people of Applefritter, have an idea what/where to look for? No chip is getting hot or even remarkible warm.

Creating 5.25 Floppy Disks from Mass Storage IIGS

Submitted by nd2003grad on March 23, 2022 - 6:46pm

This is following up on my previous post where I finally found out what was going wrong with my drives.  I'm so new to this but I have no one to ask so I'm hoping someone out there can help me.  I have  a new GS, both size floppy drives, and everything is functioning.  I have GS/OS floppy and a mass storage device.  I have figured out how to make 3.5 floppies this way from a .PO image.  My question is--can you do that as well with 5.25 floppies?  No disk shows up on GS/OS when I put a disk in--there doesn't seem to be a way to view, read, or write from it.  Is this by design or am I doing s

Apple IIGS 5.25 Boot Issue--Newbie

Submitted by nd2003grad on March 23, 2022 - 1:23pm

Hi--this is my first post and I'm a new IIGS owner.  It's not been easy so far, there's been an LCD (that does RGB) that didn't work, an incomplete mass storage device, a frustratingly non-functional CRT monitor (I'm temporarily still using composite on TV)...etc.   However, I've got one issue that I can't seem to find a solution for.  I was able to get GS/OS disks from a nice guy on a Facebook group, and if I just have the 3.25 drive hooked up it works fine.  IF I have the 5.25 hooked up (daisy-chained), the system starts to boot GS/OS from the 3.5 and displays the welcome screen but halfw

Help with Error Using MicroDrive Turbo

Submitted by OverlordSpock on March 19, 2022 - 7:46pm

Hello all! I am new to AppleFritter, so please forgive my simply jumping right in, but I'm having an extremely frustrating experience and am really looking for some assitance.

 

I recently purchased a MicroDrive Turbo from Reactive Micro for use in my ROM03 IIGS. I've heard excellent things about it and purchased the complete kit (that included the CF Card).

ProDOS ROM-Card issue

Submitted by Kingpin on March 19, 2022 - 5:30pm

I have assembled a couple of the ProDOS ROM-Card (by Terence J. Boldt) but it refuses to boot all the way to the bitsy boot menu amd it goes into the monitor when the Apple ProDOS 8 V2.4.2 screen has come up. Have tried go re-program the EPROM (no difference) and tested different slots and with a couple of Apple II's (same issue).

 

Chips have been tested as well even though they are brand new.

 

Anybody who have had some issues with these or have a suggestion?

Converting dsk images to ProDOS order

Submitted by RyanM on March 15, 2022 - 9:02pm

I have a Booti card and am trying to convert some DOS order images to ProDOS order. Some images even appear to be in RDOS order, if that makes a difference. The images in question are dsk files that I have downloaded from archive.org. I'm not very experienced at this type of thing, so hopefully someone here can point out something obvious I'm not doing.

 

I have tried the following ways to convert:

 

1) Using the DSK2PO python script mentioned here: https://ct6502.org/product/apple-ii-booti/

W65C02S Adapter

Submitted by saint on March 15, 2022 - 4:54pm

Finally recieved a real W65C02S from Mouser today and it is in the IIe with the adapter board working like a charm. I will run drive tests later tonight but having spoke with Bernardo at the Byte Attic and hearing he had no issues I am predicting all will be well. Now that I am confident the design I will put the board files up on pcbway for everyone.
