Adding all kinds of stuff to the LGR Commodore A1200 build! Indivision AGA MK2cr, PCMCIA Compact Flash, 15-pin PC joystick support, swapping the mouse ball for laser, upgrading the Kickstart ROM, along with plenty of little tweaks and fixes.

The PCMCIA issue is fixed! Turns out the memory expansion's RAM was conflicting, so I needed to move a jumper from 8MB down to 5.5MB. Not an ideal solution, but I've ordered another board that won't cause issues. Also, I got some custom PCI brackets for the DVI and USB ports!

I just uncovered an old Amiga CD-ROM in a cd binder in my shed. I couldn't find it on Archive.org so I've uploaded it here: https://archive.org/details/creative-computers Lots of of MODs, a few games, and some applications that I'm sure are all available somewhere else, but back in the day it was a nice collection.

use an old back plane from a vga card that has a dvi and vga port. That should fit the usb and dvi headers you have.

Having an Amiga and not playing Turrican is a crime.

If I remember correctly, some Ram expansions interfere with proper PCMCIA operations. You really want to use a proper accelerator board, which puts the Ram in it's own system bus, and doesn't interfere with the PCMCIA memory space.

Don't know why that cracked me up, but it did.

I'd say put in the cd drive. It's there if you need it, and its always more content.

Why not just cut holes in one of your ISA slot covers with a Dremel for the USB and DVI?

PCMCIA needs more love, I thought those cards were the coolest thing back in the 90s, one slot that could let you add a hard drive, RAM, a modem, a floppy drive, it was kind of mind-blowing.

The cable manager in me is screaming, but it is a pretty case.

Oh look a shooting Star.

I wish for a Jagged Alliance 2 review in the future from LGR.

Also Congrats on a new Intro Logo.

Hi Clint I think you should put the dvd drive in even if you don’t use it because it will look good

for the dvi and USB you could take an old video card with dvi and vga ports and remove its backplate and mount those ports to it, the usb might fit the vga hole

I'm really not impressed with that case. So many caveats.
