Issues with Novy Quik30 & Mac Plus

[SportBikePilot]

Hi all! New to the site here, looks to be a lot of great information. Trying to relive my teenage years working on a Mac Plus with a 68030 accelerator card in it, which I believe to be a Novy Quik30.

To preface, I'm able to boot the external hard disk on a Mac Classic II just fine, so we know that works.

When booting the Plus, I get "Welcome to Macintosh", several seconds go by, and I get a loud repetitive tapping/clicking out of the speaker and corruption on the display. The red LED on the accelerator card comes on. This isn't the power supply tick you hear when the analog board has issues, this is a loud tapping/pulsing sound from the speaker.

When I try to boot the system in 68k mode (hold interrupt and press reset), the system comes up, I see the SilverLining disk indicator, but it dumps back to the flashing ? on the floppy disk display, it won't boot the hard disk.

I've re-seated the accelerator, re-seated all of the RAM in the machine including use of Deoxit, all to no avail. This machine was beat to heck and suffered a fall that required a replacement case, so it's kind of a sad orphan I've been trying to get going again.

My suspicion is bad RAM, but unfortunately I don't have any spare SIMMs or the means to test them anyway. That said, I'd like to know what folks use as a reliable tester for RAM (both SIMM and DIP).

I'd love to hear some suggestions/thoughts from the group! Thanks for your time.

Cordially,

Chris

I'll add this for the record.

Appears this may be a Novy RailGun thing? It seems like one place manufactured these things and six different companies sold them, all under their own names with their own drivers.

Confusing.

I have it working properly under System 6.0.7 using the RailGun 5.x drivers, so it appears something on the software-side of the hard disk that came with it is either incorrect or corrupt.

At least I've got some spare RAM on the way that it doesn't look like I need. Future use. Once the disk drive eject gear comes in and that's done, this unit can go back together and the fun can really begin! Knock on wood.

Hi Chris,

Sounds like a neat system you've got there! My first suggestion would have been to clean the Killy clip - but you've already done that and reseated the accelerator. You mention it's a Plus - have you checked the analog board and logic board for cracked solder joints at the connector? It's a super duper common failure mode, and can present itself as an issue in a variety of ways. The accelerator is pulling additional current from the analog board, which may be enough to cause an already weak connection to go open entirely.

Good luck!
