Re: Roland MT-32 CM-32L upgrades?

in MT-32 General
This is for 2nd generation MT32s without the PGA LA32 chip, for these you simply use CM32 or LAPC program ROM and burn a new sample ROM with the extra sounds and you get all the fun. You might have to solder a wire to bring in the highest address line to the sample memory chip. 27C801 and one wire …

Re: CT3670 RAM

Take a pencil eraser to the ISA connector of the card, this will clean things up and at least rule out one problem. Perhaps try different versions of the Creative drivers, there are a number of versions around.

Re: CT3670 RAM

Ideally you need two matching sticks, your options are 2x 1MB, 2x 4MB and 2x 16MB. Parity SIMMs will work but are not good to use on these sound cards because the parity lines are not connected and any digital chip with floating inputs can do strange things. The sticks you got should mix and work …

Re: Sound Blaster: From best to worst

I actually had similar experience with one other card, I used a MC33079 and things suddenly got a lot more noisy, in addition the output current seemed to be too low and I got excess distortion from there... buuuuut those were ebay chips from china and they may very well have been relabeled LM324 or …

Re: Sound Blaster: From best to worst

It depends a lot on what is going on in the particular machine and exact opamp itself as far as the floating opamps go. The high impedance inputs are going to react to whatever can disturb them (in this case seems mostly internal to opamp) and since the loop is open, maximal gain of the opamp is …

Re: Aphex' Aural Exciter - Uh-oh, it's Magic

I briefly listened the one track I knew from these and wow, what a difference lol. I'll have to do a proper listen with something beyond crappy laptop speakers to evaluate artifacts etc. later ~ EDIT: I listened through the Depeche Mode track on big speakers now and the main negative thing I noticed …

Re: KVM switches: which ones degrade VGA the least?

Almost all the KVMs I have seen use similar kind of switching mechanism using two transistors (one for termination when input isn't selected so video card still detects "monitor connected" and other to pass signal through) and it will produce an impedance mismatch as there isn't 75ohm termination …
