Exciting. Can't wait for IDE drive emulation (even if it sacrifices the sound). Does it really matter for the end user if it's IDE or Panasonic interface being emulated ? Well, CD-ROM drives can be Panasonic's interface. IDE? That's both CD-ROMs and storage . And that's why I'm interested. HP …

I caught Adrian Digital Basement release a Book8088 repair video. He did disassemble it and put on a CGA header.

It's been a while but @yyzkevin made a video update to his Pico PCMCIA board. It's close! He's gauging interest now. https://www.youtube.com/watch?v=YoJ12leojwo

And usually most systems have need for only one parallel port. 378h I think has some conflicts with a COM port... it's been a while since I mucked with manual assignments and I'd have to dig through the RB Interrupt List...

Amazing product. I could not imagine how to manage this with a pi pico and 26 I/Os only . Great Job done ! Well, if you multiplex the data and part of the address into 16 pins... could multiplex some of the control pins as well... Adafruit PSRAM only takes 4 pins plus power and ground... so …

Nah, double the height so you can mount a short ISA card under it. lol I actually hate thin tech, I like something to get hold of. In this situation I think, losing sockets and through hole components would make it just as soulless and stamped plasticcy feeling as anything else made in the last 20 …

Well, there's FE2010A chip and Micro8088 https://github.com/skiselev/micro_8088 project. And there's PC XT core for MiSTer FPGA as well. Or you want to keep the Book form factor? It's a bit two-pronged for me. It's got it's flaws but if we can get it to run Area5150, all the better. I think that's …

I was kindly gifted with a chip with v1.06 from STrRedWolf, but it didn't work on my rev.2 Book 8088 with the v20 swapped out with an 8088. I just get "no signal" when I try to boot. I suppose there is a small chance that it got damaged in shipping, but the packaging was good, and the package …

Unfortunately it was necessary to desolder both EEPROMs otherwise the TL866 complained about overcurrent when …

@STrRedWolf About the EMS memory, is a maximum 4 MB a real limitation? Remember that most of the EMS ISA cards at the time were between 1 and 4 MB. Of course it would be better to have 16 MB, but does any software can uses this amount of memory anyway? 4MB was the LIM EMS v3.2 limitation. LIM EMS …

I assume the LCD board may have it's own firmware in EEPROM? Is the correct EEPROM linked above? Anyone know how to find out if I got the good firmware? I wouldn't refer to those as good or bad, as both has their quirks. Simplest way to determine which fw you have is to set mode 12h and see if it …

Other than that, is the serial port driven by a 16550A compatible chip or southbridge? It sounds like it is which would be better than the older serial chips the XT and AT series had in the past. Hi. My ports board on V2 has 16C550CQ chip. As for BIOS - here's features list: https://github.com/ …
