That's a very nice system you have there! :) thanks ! To tell the truth I rarely use it - keep it mostly for events, as the oldest "margin" of PC's for me is the 286 era - fast 286's like 16 or 20mhz that's is my maybe favorite era of PC's in retrocomputing... I never had a 286 PC back in the day, …

Bought that machine 4 years ago on a local retrocomputer forum... Originally it had MFM controller and ST-225 installed (PSU was replaced there many years ago by the first owner, as the seller told). I installed joystick card and ISA8->CF device. Now it works with a CGA videocard from Pravetz-16, …

P1/75 was my first own computer and back in the day it was used with win95. It was shipped with Win3.11 in 1995, though) I think 95 os ok for any pentium or 486DX4-100. For DX2-66 3.11 is better ) I recently few days ago) installed win95osr2 on one more p1/75 - Siemens-Nixdorf at my country place - …

Recenltly bought on a local retrocomputer forum that card - ATI Graphics Pro Turbo PCI / Mach 64 GX. IT was described as "excellent gaming card from 1995" there. Installed it in a P1/133 system by DEC. (Digital Venturis 5133). At least it gives a 1024x768xHi_Color option in win95 )

I don't know what board you have, but any typical award bios will have the option to reserve IRQs for legacy ISA. I use an LPT sound card and that is part of how I manage. For my system IRQ conflicts with LPT absolutely has an effect on some games but not most of them, so I typically run my sound …
