Those two little square holes at the bottom remind me of what they are — a R/W lock and an indicator of it being a 1.44MB disk or a 720KB one. Back in the daze the 1.44 disks would cost 2, 3 times what the 720 disks costs. So BF got out his eighth inch drill, drilled a hole in the 720 disks and made them 1.44s.
They worked just fine because there was no difference in the medium they used to make each disk by then.

thats how it started, Walter, but they continued doing it when that was no longer an issue.

IBM's MCA (Micro Channel Architecture) bus was light years ahead of its time...at the time :)I do believe you are absolutely correct. I was on the fargin design team for the PS/2. Which means that what we had to prove was the best possibobble results. Hence 1.44MB only for stuff we could use for testing. But... that wasn't ever thought of again (by us Engrs.) after it went out there.
Dem sneeky Sales bastages. In this age, such a simple fixeroo would never stay unknown to anybody at all.
Ha Ha Ha, yes it was — butIBM's MCA (Micro Channel Architecture) bus was light years ahead of its time...at the time :)
PreciselyHa Ha Ha, yes it was — but
IBM tried to force everyone onto their proprietary architecture and collect royalties on it's use.
Where the 8/16 bit buss was open architecture.
FAIL!!

It was still better than that huge standard keyboard connector. I remember when USB was first introduced. It seemed like pie in the sky to me at the time but it's lived up to the hype over the yearsThat is awesome. Just wanted to say that. Plugged in more PS/2 keyboards than I could count over the years.![]()

Spent around 10K on a micro channel in the early 90's then it was tough getting a graphics card for it.
It was like a 486 50mh with 32 ram.
