Hello Everyone,
This is my first post here, however I have used this excellent forum to gather information on vintage Macs and Newtons for quite some time now
A few months ago I acquired an Apple Twentieth Anniversary Mac (TAM) and have been having fun fiddling with it and upgrading it. I love the sound this thing produces and my intention is to use it as my DAW (Digital Audio Workstation) with Opcode Vision and Galaxy connected to my Kurzweil K2600xs and Teenage Engineering OP-1. Since I received the computer I have installed a fresh PRAM battery, upgraded the RAM to 128MB (max), replaced the HDD with a 120GB SD card, replaced the noisy fan on the HDD bracket with a super silent one, replaced the 256kb of cache with a 1MB L2 Cache card (this accelerated the 603ev quite a bit) and installed MAC OS 9.2.2.
I recently acquired a Sonnet Crescendo G3/L2 350 Mhz/1MB card and wanted to upgrade the TAM with this card. I installed the software v.2.3.1 (which came on floppy with the card) and replaced the 1MB cache card with the Sonnet. I made sure the card was firmly pressed in the slot, however when I turn on the TAM it does not boot. I get the boot chime but the "Happy Mac" icon does not come up (screen does note even light up). I have tried removing the RAM and the IDE HDD to see if these were conflicting with the Sonnet card, but there is no change. I disconnected the PRAM battery so that the PRAM would be wiped clean (and even pressed the little black round button next to one of the RAM slots), but again this made no difference. When I reinstalled the 1MB L2 Cache card the TAM boots normally. I tried installing the Sonnet card several times, but I get the same result.
I don't know what else to do. Did I receive a bad Sonnet card? Physically the card looks pristine. Any help would be greatly appreciated. Thank you all in advance.
Cheers,
Igor
