There is no rush, my first milestone would be to have a working doubleslot replica then we build from there. That will be at least two weeks, as it will be at least a week before I send off v1 pcb. My personal selection of old laptops/palmtops is limited, aside from the LX's I have my IBM PC110's …

if you run dtpl.exe -r 1 > dump.cis and attach that dump it would have what I am looking for. you need to run it on a laptop with normal card services though, does not work on the LX. Do you have dtpl.exe on any of your laptops within the card services etc? I hate to attach/distribute .exe files if …

There were a handful of fax/modem cards sold for the palmtops that also had flash memory on them, to avoid that chicken and egg problem of connectivity through pcmcia but low storage... Or the serial port floppy drive, which was a computer in disguise if I remember correctly, one such model was …

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 need …

On the topic of PCMCIA audio, has anybody ever seen the connector used in the Roland SCP-55 on any other product?

That is how it goes, when you are looking for it you cannot find it. I was not even sure what this was, but it seemed relevant to the PCMCIA work I have been doing so when I saw the user put it up I said yeah I'll take it. https://imgur.com/gallery/I1Oo5pB

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 work …

I already modified the the NE2000 emulation in Dosbox-X to use a UDP tunnel to connect to my cloud hosted virtual switch instead of using pcap to the local lan and it works great.

I actually was thinking about doing this also. Initially I was using a "wifi232" module I found which exposes an ethernet PHY, which I was coupling PHY to PHY on a salvaged PCMCIA card for testing. I had some issues and support from the company was not good on debugging the PHY. I purchased some …

Sorry to revive this old thread. I was just wondering, is there actually any interest or new info on the topic of an ESP8266 ISA card?
