I have been experimenting with these shaders. There are couple of decent ones, though those new Dosbox Staging shaders look like the best that exist I've been playing around with CRT imitation shaders ever since this option was available in DOSBox SVN Daum. To be perfectly honest, I've not used a …

Greetings! I have had great success using my OSSC with an LP2065 and getting a decent picture at 70Hz for MS-DOS games. As of now, I have as Pentium 3 connected to the OSSC, using a 4k freesync TV, as I was rebuilding it and putting a fresh install of, well, everything on it. It is a lot easier …

An old post on another forum site from around 2000 has someone claiming that Diamond Supra Express modems are hardware modems, and Supra Max modems are winmodems. Anything requiring a Pentium 100 and up is supposed to be a winmodem.

Yes. That looks like a good hardware modem. V.90 bis AND x2 There were 3 standards for 56k modem, and v.90 was the best one. KFlex was the 3rd one, and was rather maligned. But if you really want a diamond multimedia card... this is also a jumpered modem... https://www.ebay.com/itm/254461904732? …

Though it isn't a Diamond product, this U.S. Robotics modem looks like a viable solution. It has jumpers on the board, and the system requirements lack any mention of a required OS: https://www.ebay.com/itm/204158294331?_trkparms=ni_actn%3Anav%7Cni_nt%3ASellerInitiatedOffer%7Cni_apos%3A1%7Cni_sg%3A1 …

The sound and modem section shared a codec. If you used sound at the same time the modem was limited to 14.4 due to bandwidth limitations. AMR modems worked in a similar fashion, they basically used an AC97 codec with the CPU doing the rest of the work. That makes sense. I have seen many soundcard- …

The IBM HSC crap, at least, DID work 'acceptably' in highend (for the time) pentium systems. (Even if they did make the system lurch to a crawl the instant dialling happened...) They needed the processing power because the "modem" was just an ADC and the signal processing/decoding had to be done in …

Holy grail of ISA modems is U.S.Robotics. I came across a pdf manual of some form of 56k U.S. Robotics modem, and it mentions Windows 3.x support, so I think I need to hunt down that particular modem and give up on the Diamond brand name, hehe. If it works under Win 3.x which runs on top of DOS, I …

The typical setup would be to connect the midi side of um one to the retro pc via the sound card mpu401 uart. You will need an adapter from db15 to din. The um one will then send the midi to the device you connect by usb. For mt32 you will need softmpu tsr or isa card that provides hardmpu support. …

This old Gateway 2000 modem has "1994" printed on the pcb, and a sticker from 1/25/95, and it has jumpers instead of dipswitches. It should work, but definitely not a 56k. I'll research it later on and try to post a pic of it. It is probably a 28.8k modem.

As long as the PC supports "fast" 16550 UART I would have thought external is more desirable? flashy lights are sexy :) Out of interest what are you using the modems for? just the BBS's or some project? I do want to visit some BBSs and have considered starting my own. I think that it would be cool …

There *were* very early IBM HSC modems that were ISA. They used the isa plug and play bios extensions to get configured, and were basically just a crappy soundcard. See for instance, here, with this 'it's obviously lucent' and being 8bit isa. Note the complete lack of config jumpers. https://www. …
