XP on the 2ghz celery I have can’t handle 100’s of photos on a phone at all , even w/ 1gb of ram. The way systems handled large external volumes improved on Eindows 7+

P4’s were in colleges and Businesses certainly but my school virtually ignored P4 and where I worked stayed with P3’s and Win 2k until 2012 and jumped to Core & Win 7 skipping XP and Vista. In the engineering world AMD seemed to be more popular during the P4 era.

When the p4 was contemporary nobody I knew owned one. (They were an elitist machine). Most everybody still had K6-2 or Celeron/P2 machines. And then like a year later Athlon/Duron My school had some random P4 1.3ghz & 1.4ghz machines but they shoehorned them into rather low end applications...

Windows + EGA + 8088 = :(

It did work 640x200x16 color (Windows 2/3.0 real)

When did 64k boards stop manufacture?

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.

Ditto above, I wonder if it adapts to GPIB / HPIB or relates to old pos scanners / equipment. Hmm digital I/O?

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...

Nope

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...

Bytes, Nibbles and bits go back a very long time. I highly doubt the definitions were different in 1970 than today.
