137.90 US dollars. I hated being late to the project. I don't know if I overpaid, probably did. I still have to get all the parts. I've been wanting one of these forever and a day to use for music production. I think I'm an artist, but life doesn't agree all the time. We overpaid too maybe 30% less …

Was gonna suggest Logic Analyzer, didn't because you know your thing. I also think delay will not be significant and that is another selling point for this card. I am not sure if it is discussed here but next natural step for this to have a PCMCIA version of the card. It will be very useful to …

Yeah I checked the wiki and see you use OpenWatcom to compile. It looks like it has some optimization option for 286/086. If I ever build the card I will test it on my Tandy 1000, I have 100 projects on wait list to order PCB and source parts. It will be a cool add-on at least for experimenting …

I haven't read most of replies here. I tried to search in google but didn't find anything. Does PicoGus drivers/setup software work on XT class machines like Tandy 1000.?If not will upgrading to NV20 help?

Great info here. Reminded me of how much time it took to source parts; some parts are obsolete and you need to find similar one with matching spec and footprint, some are only available in other grades or tolerances e.g. more expensive automotive grade. If you are motivated it is not bad and can be …

Hi everyone, I've recently acquired one CM-11 with broken tabs on one side of panel door. The tabs are kind of delicate and not easy to recreate with glue or metal paper clips, I am not familiar with 3D printing and neither have a 3D printer but if anyone here can help with some resources or designs …

No you are not crazy I did the same thing. Be prepared to spend couple of hours, don't let comments like "I finished it in 2 hours" let you down. Follow the guide/zip file in the initial post for software and programming board. Also be prepared to debug; use microscope or any other magnification to …

I also did the mapping, turned out to be same as yours. On internal side, DS wire is connected to DS0 of internal drive, externally we should also connect it pin selected by drive (e.g. DS1 for DS1-set drive). I will order some 30 pin edge and 34 pin ide connectors then will make a prototype on …

As far as I remember I did not run into any other problems. I was able to play MYST with working audio and video. For those who still looking for solution, I followed the instructions on this page and it fixed the issue: https://support.dynabook.com/support/viewContentDetail?contentId=107632 It …

Hypothetically, could I use the toaster oven soldering method, or would that damage the Interwave? If you use same temperature ramp up and down used to stick Interwave in the first place, I don't see any reason not to. If you have experience with the same size boards and the same type of solder …

Finally done, so much trouble with solder paste, broken amp chip, weird software setup, but I am happy with the end result. I am really surprised by sound quality of this, the clarity beats classic GUS, AWE32 and all software trackers I've tried so far. A recorded tune is attached. What RAM did you …
