bot devices led and lcd plug into serial ports (which is a problem in itself, as my optipac also uses a com port)
finding Motherboards with more than one standard serail port is next to impossible nowadays
and by standard I mean
COM1 3F8 IRQ4
COM2 2F8 IRQ3
COM3 2E8 IRQ4
COM4 2E0 IRQ3
(those whom existed before PnP know whom you are)
I also have the machine interfaced to my TCPIP network (DOS CLIENT)
Sound is comming from a PCI SOund Blaster Live
getting a motherboard that has what I need and allows the devices to play well with ine another in DOS is nowadays nearly impossible and since MAME is no longer compiled for DOS, the whole sense of it all is quickly fading.
I am very close to switching to a WIndows environment possibly TinyXP (TIny/hacked version of XP), only thing that hurst me is that it actually took me several years to track down one of the ArcadeOS Programmers (Carlos Santillon) and another while to convince him to help me with this project only to have DOS support for Mame dropped about a year later.
I also deviced a means by which control panels could be swapped in the cabinet by using Spring loaded centroniccs connectors, my next project was to have Carlos help me program into ArcadeOS the ability to detect what kind of controller was plugged in, joysticks, Drivign wheel, roller ball etc and have it display the list of according compatible games only.
needless to say this never came to fruition.
ALso if anyone out there knows whom is maintaining the ArcadeOS site/links, I still have a copy of the previously unreleased (ArcadeOS 2.53) with support for multiple serial ports. I would like to get out there before it is lost forever with Permission from Carlos Santillon of course.
