IVS Trumpcard – Part 1

The Plan

I’ve got a couple Trumpcard SCSI add-in cards for a Zorro-II slot. My plan is to make a step-by-step instructions to installing and configuring it.

The scope is to install the card in an A2000, add a SCSI2SD adapter, and get everything to boot on my latest A2000 project box. The project box’s serial is RN2205009. A rev 6.2 mobo with some light battery damage. I picked up the box as a no-boot Amiga.

Prep Work

Unfortunately, the A2000 suffered physical damage when being shipped. PLEASE don’t ship an A2000 (17 1/2″ wide) in an 18x18x18″ box >>> something will always be damaged. For me it was some bent metal (meh, I could live with) plus a smashed face. The face had a couple glue points from 5-20yrs ago but now all of the points are broken.

First, gotta reseat all of the cards and try a boot. Remember, things shift and move when shipping something that size and weight. No joy. The cards were a

Next step was to pull out the Varta battery with some needle nose pliers, check. At some point I plan to solder in a coin cell . The next step was to test boot with no cards. Holy guacamole, it booted to WB 3.1 (sweet!).

I installed my gotek, as drive 1. Moved the Chinon FB-354 from DF0: to DF1:, added a jumper to J301. This jumper is right under where the FDD cable connects on the A2000 mobo. And now I have a dual FDD booting box. Mind you I’m skipping a bunch of testing and swapping FDDs to get to the end point.

Linux USB Audio

Just a quickie note. Probably more for me than anyone else. If you are running Linux and your audio deteriorates over time (noise/static/volume lowers), it can usually be fixed by replacing your audio chip. Linux support for audio chip is just meh. I used the Sabrent AU-MMSA. It plugs into a USB port and you plug your speakers/stereo lead into that. I’m a fan of LinuxMint my hardware ranges from newer AMD Ryzen 450/550 boards to old HP Z420 workstations. The chipset in there is solid under Ubuntu.

Sabrent AU-MMSA

It comes through as a Unitek Y-247A chip. I’m sure any device that uses this chipset is good to go. These cost under $10 from everywhere. A simple fast fix for your Linux audio irritations.

I haven’t tried the microphone-in plug. Have you?
