I posted on vogons using my 200lx some time ago: https://www.vogons.org/viewtopic.php?p=787032#p787032 Several books about the 100/200lx were published in Japan, like the hardware/software/internet bible series. The hardware bible has chapters about pcmcia serial, parallel and pcmcia devices, did …

>lab username is guest that is a nice render. I could build the circuit board for that in a day or so, mostly. an issue though is, when the onboard LPT1 is enabled I believe I would need to disable one of the slots. And, the OPL chip when enabled would use that same LPT port, otherwise we would …

Hi again yyzkevin, I let my imagination loose and made a quick 5 minute 3d model of "The Imaginary Penultimate Expander" for the 200LX ;) This would be a device that slides into the PCMCIA slot on the left of the HP Palmtop, similar to those Amiga 500 hard drives that attached on the left of the …

Also, i'm not sure if it was you, but you (or someone else) pointed to "yahoo auctions" for looking for things like an SCP-55 PCMCIA soundcard and a such, but after some googling it seems that there are only 4 yahoo marketplaces all for asian countries. Which one should I look at ? The japanese one …

On the topic of PCMCIA audio, has anybody ever seen the connector used in the Roland SCP-55 on any other product? I was hoping to find another cable I can salvage the connector off or search for new old stock connectors. I have other types from hirose etc but nothing quite like this. I want to make …

I do see there is the VXPocket V2 listed for sale on ebay (multiple of them) with quite a wild array of input/output connectors including xlr not sure if balanced or not, but according to the matrix in this thread though it is not supported in DOS so not useful to us.

Hi Terrence ! Listening to your recordings, I have the impression that the processor may not be able to cope at certain moments. Maybe lower the mixing speed a little? Try this module: 3d demo tune(mf) I have listened to it countless times. I will tell you for sure :) BTW. Nice little machine ! Hi …

Yeah my HP200LX has upgraded memory and clock speed so not an issue for me but I also have an unmodified one I test stuff with. My main intention was for an onboard ESP8266 which presents as a standard serial/uart, and to meet the current limitations of the HP even under transmit which seems to …

Nice selection of tracks :) That little setup is incredible - especially knowing it's all coming from an 8086/80186 class processor, the mouse really tops it off I think. Have you tried out PS/2 to serial mouse adapters with their own power source to see if that helps? Then you're not tied to that …
