Hey guys, i have a questions.
I am building an 486 DX system with the following (current) components:
Motherboard - Unknown model > Symphony chipset 6X ISA / 2X ISA+VLB / 30PIN SIMM 32MB MAX / 256kB CACHE 1MB MAX (Made in USA)
CPU - 33MHz DX CPU (Thinking of using AMD DX2 66MHz, or if found DX 50MHz)
RAM - 16MB 50ns (Thinking of using 32MB 60ns)
VGA - Tseng Labs 4000ET
AUDIO - I don't know, i will use a little bit of this and that, thinking of using Crystal CS4236B for a while
And now the main question - I want to use SCSI disk and CD ROM in this thing, so i got my self some controllers.
They are:
1. Tekram DC-300B (Has 256k x 16 cache chip)
2. Adaptec - AHA1542CF
3. Adaptec - AHA1420B
The disks i have are IBM UltraStar models 2x4GB and 1x2GB.
I know that transfer speed in the ISA bus is limited and having cache would probably give better performance, but Adaptec models are very good also. But i am not sure of small detail differences between them since i couldn't find an Tekram manual.
I am planning of getting an cool VLB Tekram DC-800 controller one day, or some other maybe (16MB CACHE - My 50ns RAM modules would come in handy here), and some VLB VGA card as well, maybe ET4000 W32P.
But for now i want to use what i have.
