thanks for the kind words guys well I do have 20x FPGAs already 😉 the lead time for any more ranges from 7 weeks to 46 weeks 🤣 we are just the bottom barrel fish, the fpgas that end up in the market are what are spared from buyers that get them by the thousands....

No need to make recordings to prove anything 😀 Ofcourse there are good cards out there, it's just that the majority of als100 cards are indeed very cheaply made , I should have phrased that better.

I've had a somewhat recent experience with ALS100 chips sourcing: they are both rare and expensive. Which makes no sense because this was a chip on the budget side - unless maybe the whole stock was depleted and you can hope for is a small quantity here and there... About noise, on these cards it is …

Looks awesome Keropi! Do you have an estimate on how much The Mega Card will cost? :) I want to say something like 200~220eur shipped? it's not finished yet - some stuff are added and I actually want to see how much time I need to solder one of the final versions availability will be pretty low and …

Looks fantastic - can't wait 😁 - btw will the connection from the scan doubler to the mega drive clock have a connector on the soundcard side so that they can be easily separated ? yes, it's just a 2pin header so it is detachable on the megacard side - on the amstrad side it needs to be soldered in …

[...] I have a question... will the original Game port still work when adlib sound is disabled on the MD card? the correct course of action would be to disable the amstrad adlib and use the OPL3 on Mega Card :D disabling the onboard adlib is very easy, lift pin19 of U1 74LS245 and connect it to …

@kolderman all I can think about is a connectivity issue - the green light on the midi-thru device does not mean that you actually get a midi out signal so maybe it is a bad cable? a bad midi adapter? a bad jack? if you have a pcmidi with wavetable header install a wt board there and see if you get …

you do not detect it on the device, you select it from a list and tell the device what it is that you inserted... there is no auto-detection

I would feel safer if the card was tested on some random other system that is not branded... then go on to replace isa slots etc it seems that almost all serious issues we faced are because of OEMs and their early adoptions of PnP standard... dell, olivetti, gateway (perhaps) the fact that CS4237 is …

but did you clean the isa slots? assuming the card is bad it does not explain moving it in other slot and getting it half-working if you did then you can return it for checking to replace or refund , I cannot think of anything else to help you

I got serious today and stripped the machine down. I swapped my cards around and put the orpheus into a different ISA slot. Magically it works....to a point. Now with Orphinit and Unisound theres a crazy echo. I'm sure this is a known issue that I haven't gotten a chance to research. hmmm no this …
