when you are trying to revive an IBM 5150, that :
- you do not have a single AT powersupply in the house, just 20 ATX PS
- do not have a single PC compatible keyboard, but 10 AT & 10 PS2 keyboards
- at least 50% of your MFM drives have passed away in their sleep.
- you don't remember which is the last DOS version that runs on a standard 5150
Time to grow up I guess.

Its funny that I have a basement full of old PC equipment yet only have a
couple MFM drives (SCSI is my drive of choice for old machines). How do you
have MFM drives and nothing else of that vintage around?

Aside from the -5 line (which can be gotten with a 7905 voltage
regulator off the -12 (and may not be needed for anything but the
original 16-64K 5150), most ATX supplies can be pressed into service
for AT use, mostly by changing the connector and manually toggling
the "power on" lines. The guts of an ATX should easily fit into an
AT style PSU enclosure.

Too bad you're on the other side of the pond from me: I have a bunch of those old AT
supplies that I'm resisting sending to recycling. I'm just done with PC stuff,
but I hate to just dump this stuff because, well, there's always someone like you who
needs it to feed his jones.... -- Ian

Same here. Just got offered half a dozen on Freecycle last month, too. :?(
Jos: for my money, MS-DOS 3.3 was the classic version for the original
PC. With <=640K of RAM, no full-function version of DOS offers as much
functionality in as little conventional RAM. All the later versions
are bigger but normally hide bits of themselves in the HMA or UMBs to
maximise free base memory, which is no help if you only have base
memory and nothing else.
DR-DOS 3.4 might be worth a look if you can find it, but it's obscure.

I think the DR-DOS family tree went something like:
CP/M
|
v
CP/M-86 -> Concurrent CP/M -> Concurrent DOS -> CDOS/386 -> Multiuser DOS
etc.
|
v
DOS-Plus
|
v
DR-DOS (which also had some input from CDOS but I'm not going to try
to do it in ASCII!)
DR-DOS released versions went:
3.41, 5, 6 (from Novell), 7 (from Novell, then Caldera, then Lineo,
then DeviceLogics), 8 (from DeviceLogics)
DR-DOS 7.01 or 7.02 was open-sourced. 7.03 was closed again but the
7.01 or so branch begat the OpenDR-DOS Enhancement Project, but that's
now been overtaken by FreeDOS, which in turn has kinda withered on the
vine.

1000 years easy if kept from the elements. As far as running condition,
capacitors will need to be replaced sooner or later. Who knows what a modern
computer will look like in 200+ years (could be an implant in your brain by
that point), or a C64 running off of a waterwheel after WW3 is over.

when you are trying to revive an IBM 5150, that :
- you do not have a single AT powersupply in the house, just 20 ATX PS
An AT supply isn't a good fit in a 5150 case. Look for a PC or XT supply.
XT supplies have enough power for "medium" size MFM drives.
- do not have a single PC compatible keyboard, but 10
AT & 10 PS2 keyboards
- at least 50% of your MFM drives have passed away in their sleep.
The 5150 didn't originally have a "fixed" (veterinary context?) disk.
- you don't remember which is the last DOS version
that runs on a standard 5150
For reviving the machine, any will do.
1.10 or above for double sided drives
2.00 or above if you want 9SPT, subdirectories, hard drive, etc.
2.10 or above if you have a lot of non-standard hardware
(2.11 is MS-DOS only, and often already has weird add-ins)
3.00 or above if you want 1.2M (HD floppy controller
3.10 or above if you want a CDROM with MSCDEX, etc.
3.20 or above if you want built-in support of 720K
3.30 or above if you want support of 1.4M (HD floppy controller!)
3.31 or above if you want a drive larger than 32M
6.00 or above if you want built-in support for compression
Time to grow up I guess.

Depending on what you mean by 'standard' then everything up to PC-DOS
7/PC-DOS 2000, or MS-DOS 6.x. Both of those need 640K I think, acording

Just guessin.
This relates to the A20 switch logic, and access to mem above 1M.
It was eihter switched off and wrapped around, or enabled.

I run PC DOS 2000 (7.0 with y2k fixes) on my 5160 just fine. It's nice
using 2010 as a date and having it actually work.

No, but QRAM + a real hardware EMS board allows me to load TSRs high

I have the oposite problem. My IBM Type M is playing up (needs taking
apart and the heat-stakes replaced by screws...) and I don't have another
AT or PS/2 keyboard in the house. Got a few XT ones, plenty of HP-HIL
ones, LK201s, etc...
- at least 50% of your MFM drives have passed away in

at least I know where my 5150 techref is...
