Does anybody have any ideas on how to add a real OPL2/OPL3 chip to this box? For example, there is an OPL2LPT adapter that outputs OPL2 over a parallel port that can maybe be exposed on the weeCee? Any other ideas? I know the Crystal chip onboard supports an OPL2 clone but I'm wondering if we can …

I'm currently using a Rolls MX51s Mini-Mix 2 3+1 channel audio mixer but I need a few more inputs. I love the mixer but I can't even use the 4th input because it's a mono (?) XLR (?) input. I'm looking to connect my MT-32, SC-55, RetroWave OPL3, and one or two other devices. Can anybody recommend …

Has anybody been able to run FASTDOOM (VBE) under MS-DOS with this setup? According to SciTech Display Doctor (VBETEST.EXE), this chip supports VBE 3.0 and DUKE3D/QUAKE also seem to be running fine with VBE modes. However, when I try to run FASTDOOM (FDOOMVBR/FDOOMVBD), it crashes . (I'm only trying …

What 3D accelerators were available when Quake 2 was released? I'm trying to remember what card I had back in 1997 (?) so I can recreate a bit of my childhood. For some reason I think it was a Canopus Pure3D but they are selling for INSANE prices on eBay... What would be considered the best 3D …

I've purchased the Tripp Lite 0DT60002 USB to PS/2 adapter and it was ridiculously expensive ($72 on Amazon) but it works perfectly on the weeCee. I'm using a USB KVM (ie. USB hub) but the Tripp Lite works perfectly. The USB KVM goes into the Tripp Lite and it separates and converts both my gaming …

Yes, you can get one of these adapters: https://www.tripplite.com/ps-2-to-usb-converter~0dt60002 They work fine, but are quite expensive. I paid ~$50 for mine. Alternately, there is this project, if you're willing to DIY: Is that the adapter you are using? The reviews mention if you use a mouse …

Got it... thanks again. I think this has been posted but the USB controller seems pretty buggy. If I connect a USB keyboard it works, but if I connect a USB hub with a keyboard and mouse it freezes the system or causes an "Internal stack overflow". Are there any clever solutions to convert a USB hub …

Thanks for that detailed information! I've actually just received my DB15MIDI and Dreamblaster S2 a few minutes ago in the mail. I also have a bunch of other devices that I experiment with: * MT-32 (real hardware) * MT32Pi * SC-55mkII (real hardware) * Dreamblaster X2GS (coming soon in the mail) * …

Does the Crystal chip have onboard MIDI capabilities or does it require a wavetable board? I have a Dreamblaster S2 coming but I was wondering if I could switch between the onboard and wavetable (using DOS) and test the difference? If so, how do I switch between them?

Does it fit inside the case with the solder tabs still attached? In your picture it looks like the top tab is broken off. The fit inside this case is definitely very tight!

Thanks so much for the information. Everything seems to be working perfectly on my weeCee. However, I ordered a CR2032 battery and it's definitely too big. Amazon seems to only have CR1616 (as the smallest size with tabs), so I might give that a try but what size battery did you use? (if any?)

One more question (in addition the ones above)... How difficult would it be to make a revision of the mainboard to make a few changes? 1) Add 2x serial ports (from the SoM) 2) Add 3.5mm line input (from the Crystal sound chip) 3) Add a USB hub chip (ie. Terminus FE2.1 4) Increase power input (DC …

I think you misread me. R10 has to stay unpopulated. R19 also has to stay unpopulated. Only 2 pairs of pads aren't populated. R10 associated with the EEPROM and R19, part of the "pc speaker" signal. Sorry, my mistake (again). However, the BOM.xls lists R19 and R21 as "DO NOT POPULATE". It also …

OK - No problem... I found an extra 6.8K resistor for R10 and I was also able to desolder a DB15/VGA connector. Getting ready for first power on!

Is R10 supposed to be populated? It's listed as 'NP' but it has a description instead of "DO NOT POPULATE". EDIT: Can you also verify the VGA connector? I've finished building everything and was ready to solder the VGA connector but the part number in the BOM seems wrong? (ugh!) The BOM lists …

I also contacted ICOP but they asked me to through a reseller (WDL Systems) and I paid $183 + $17 shipping. They were extremely helpful and I received it really quickly. Tomorrow my PCBs arrive so I'll be able to get started with assembly and I'll post pictures and results 😀
