Microsoft & Apple

by Murray McCullough

I had not realized it was 27 yrs. ago that Microsoft ‘gave’ Apple $150-$200 million. It was done to keep Microsoft safe from regulators - for its monopoly practices. Later did the lawsuits end between Apple and Microsoft. Did this save Apple? Haven’t researched this enough to deduce a learned response! Happy computing, Murray 🙂

Punch card info

by cctalk＠emailtoilet.com

Was updating my punch card database/site, www.ibmjunkman.com, and found something I don’t remember. The 026/029/129 keypunch units printed above row 12 using a dot matrix style character. I still marvel at the plate and the whole mechanism that did the printing. The 557 Interpreter could print on different rows using a solid type slug to print. I have run across cards that had dot matrix type printing on rows other than above the 12 row. Any idea what machines could do this? If any of you old unit record guys have any cards laying around I would love to add them to my collection. Needless to say the stock 5081 would have to be real unique for me not to have it already.

Looking for Sharp PC-5000 disk drive (CE-510F or possibly MZ-80B)

by Steve Lewis

A while back I started studying more about the Sharp PC-5000 (and had it up and running at VCFSW in 2023). I'm now coming back to that project, and one thing I was never able to find was a compatible 5.25 disk drive. I've collected some information about this system at here: https://voidstar.blog/sharp-pc-5000/ And I am hoping to put together a video about out. But one challenging aspect is that its LCD screen is difficult to record (lots of reflections). And despite having lots of schematic documentation now, I'm still not savvy enough to try to export its screen content to an external device that might have a backlight. From my notes, as I recall.... The 37-pin connector at the back of the PC-5000 is not the same as the 37-pin connector at the back of the IO card with the original IBM PC 5150. I believe the Sharp product model number I am looking for CE-510F (which might be the same as MZ-80B in certain markets). This isn't an urgent thing - the Bubble Memory modules of this PC-5000 are still all working fine and make the system functional. But I do have a set of disk with the system that might be interesting to try out. So just broadcasting here, on the off-chance someone might be familiar with these and know of a stash of accessories (most likely within a Japanese-speaking community, where I think Sharp products were generally more popular). Thanks! Steve v*

MS-DOS

by Murray McCullough

I had not realized that 43 yrs. ago Microsoft purchased 86-DOS for $50,000 – US not Cdn. money. With this purchase the PC industry, IBM’s version thereof, began. I remember using it to do amazing things, moreso than what 8-bit machines could do! Happy computing. Murray🙂

WTB/Borrow: RK05 Alignment Pack

by Jonathan Chapman

All, I'm getting ready to dig into my RK05s, two of which are parts units, of which I hope to make a functional unit. I will definitely need to align it as heads from one will have to go into the other. Does anyone have an alignment/CE pack I can buy or borrow? Obviously prefer pick-up at VCF MW to avoid the possibility of shipping loss or damage. Thanks, Jonathan
