RiscPC PC Card

Post by markdryan » Sat Jun 30, 2018 9:43 pm

I've just acquired a PC card and am amazed at how well it works and how nicely it integrates with the RiscPC. I realise the computer was designed with PC support in mind, but nonetheless, I'm really impressed. So much so, that I thought I start a PC Card thread. There doesn't already seem to be one and I thought it might be a useful place to collect hints and tips about using the card.

Initially I had some problems getting the card to work. The software on the disc that's supplied with the PC Card is not compatible with RiscOS 4.39. I needed to download the latest version of the software from http://www.riscos.info/index.php/PC. PCConfig requires a patch to work on RiscOS Adjust. The link to the patch on riscos.info is broken. However, I was able to find a copy of the patch (don't remember where) by googling the patch name (PCconfigPatch.zip).

To get the CD drive working in DOS I needed to download the "Sources for various PC card drivers" from http://www.riscos.info/index.php/PC and use the HPc_cd.sys driver. The driver mentioned in the PC card manual, A1cd.sys, did not work for me.

So far, the only DOS application I've really tried is UFO, which works perfectly, albeit without any sound. Which leads me to my first question. Does my RiscPC need to have 16bit sound to get sound working on the PC card?

My second question is, what software recommendations do people have for the PC Card?

I've installed the Open Watcom compiler but haven't tried it yet.

There was various cool stuff possible with the PC card - like the early Linux port by Mark Brinicombe, or ARMASPI by Andreas Walter which allowed access to every SCSI device directly from DOS and Windows software. And Windows 95 with Netscape for sensible Internet access via the "I am two networking cards" feature of the EtherH.

I remember letting Doom run in the PC card window when presenting the Risc PC on German computer shows, along with a few Replay windows with the few high quality movies available. And then drawing something with ArtWorks and dragging the result into Impression. Totally pointless, but it really amazed the visitors back in the Windows 95 days :D

In theory, "Win,Risc" would have been the real PC card killer application. It crashed all the time however and worked only with very few software reliably. Then, the maximum amount of memory usable from the PC side became a constraint, along with that lousy 486DX4-100 CPU. Before that, quality of emulation was the problem - it was not really a PC card, but a x86 CPU with an emulator capable of running DOS and (certain versions of) Windows. No OS/2, no Linux (the effort by Mark was quite shortlived and not really stable), no BSD, no Windows NT.

Have fun

I'm afraid I can't remember, I set up my PC card a couple of years ago but I wasn't sure I got sound going, I did get the network card to work though!

I setup Windows 95, got old versions of IE and Opera going on it for internets. I installed a couple of games too

Stars, https://en.wikipedia.org/wiki/Stars!
MS Flight Sim 95 [1], https://en.wikipedia.org/wiki/History_o ... Windows_95


[1] This was a bit lacking in framerate on the 486 sx 33, but just about playable. I think it would be better on the fpu enabled faster 486 dx.

I think the original PC card software only did the internal PC (buzzer) sound output.
I have the extra aleph 1 sound stuff somewhere that allowed it to pretend it had a soundcard on the PC side.
I'll try to dig it out. What version of the PC card software are you using.

Looks like the soundcard emulation software is included in the one you are linking to.
You have to install the driver on both the Risc PC and DOS sides.

It seems to the in the "Sources for various PC card drivers", not sure if its been compiled as part of the community downloadable version.
