Brave man! FWIW, possibly the optimal DOS for that machine would be DR-DOS 3.41. It's as small as MS-DOS 3.3. All later DOSes (MS or IBM PC DOS 4, 5, 6, FreeDOS, etc.) take more base memory and rely on tricks with high/upper memory on 2386 and 386 chips to sideline most of it. DR-DOS 3.4 does >32MB disks and has command editing and things, but it's tiny and is the smallest but richest DOS for an 8088/8086 PC. Only the upgraded PC-1512 (and the later PC-1640) had 640kB of course. Stock models had 512kB, thus the number in the model name. Which makes this even more important. There's a tenuous historical justification: the PC-1512 shipped with DR DOS-Plus in the box, which is an ancestor of DR-DOS. -- Liam Proven ~ Profile: https://about.me/liamproven Email: lpro...@cix.co.uk ~ gMail/gTalk/FB: lpro...@gmail.com Twitter/LinkedIn: lproven ~ Skype: liamproven IoM: (+44) 7624 227612: UK: (+44) 7939-087884 Czech [+ WhatsApp/Telegram/Signal]: (+420) 702-829-053 _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
