If it’s early it won’t be marked either way.
Sometimes the first batch were 32bit clean.
I owned one where the person purchased a “bad” 386 beige box full tower on purpose to save money.
Really sucked because it actually couldn’t run as much software as a 286.
It is if you can remove the disk interface overhead. Physical ram as virtual memory only requires an extra address instruction to decode as compared to in address ram, add the drive layer and max throughput drops fast.
A ram device that is not behaving as a disk drive has a max output of about...
I can easily have 64mb of virtual memory as it’s not tied to any physical address limit. Even with 2mb of ram in 386 enhanced mode I have a 20mb swap file setup and can run (very slowly) software that is designed for 8mb+ minimum.
And I’m not able to expand its memory past 2mb and when I’ve...
A more fruitful endeavor (possibly) would be to fix windows 3.1/95 memory service to directly support using virtual memory on an ISA/VLB or PCI card so the multitude of machines that had very low real or artificial memory limits could have a slightly faster memory option.
As an example I have a...
In theory that should be good for 20mhz right?
Kind of an odd speed grade, unless it really overclocks many FPMs can cycle that fast (after the initial read on burst)
There used to be an app (I believe made by a member here) that could scan the entire memory map on your system .
You could then install the mystery memory run the app and get the start address and memory size of the adapter you installed . Note the jumper settings.
Change one of the jumpers...
I’ve often wondered why “Tandy sound” usually had inferior sound effects as compared to the master system which used the same chip, I have to guess less expertise and budget?
iMP mark on the CPU appears to be a subsidiary of National, considering neither national or its overseas compatriots never made a 286 (that I’m aware of) must be a evolutionary dead end.
Sort of like the ns486 or N7 that only existed on paper
I never did understand why XT286 motherboards were a thing
they weren’t that uncommon and Tandy made a business of having XT class motherboards with 286 processors
Kinda breaks the point of having a 286 board when you can’t break the 1mb barrier, have XT DMA & IRQs and are stuck with everything...
There was one from the 80’s as there is an active archivist who “has them all” (not quite) and is slowly processing them

Most scammers are shielded in certain foreign countries in legitimate businesses.
Generally we know who and where they are, eliminate about 6 of these high rises and 95% of scam calls and 80% of “hacks” would end for a period of time.
If we wanted we could certainly fight this rather...
Mine has an external little narrow box/bracket that snake through there off the multi-function card with clock that sort of just hangs off the sheet metal sandwiched by the case cover, gives me an LPT and game port on the top edge of the rear of the case, even has a grommet in that hole
There are utilities that will resize a partition even if its formatted with data.
He could do that so there is leftover space, I can’t imagine Compaqs bios requires more than 5mb, likely a lot less.
Oddly printers of this type first came out in the 90’s
There were ways of dealing with the banding by using a very coarse half tone. Folks that did stickers, foil and other novelties didn’t have to worry about banding because they only printed solid colors.
3rd parties at one point offered...
