Yes, see the service manual (online at manualslib.com).

This is what the official tool looks like. I'm sure you could probably roll your own. Note the all-plastic construction so that the case...

Yeah, the 1052 looks quite a bit beefier. First cousin to the 2741.

I think that it's a simple display control for data/address lines. Definitely homebrew, right down to the repurposed telco wire. (brown-white and black-white). Note the 18-bit address. What we...

Was that console typewriter the direct descendant of the 1052? (My experience extends only to the S/360 stuff).

Well, around the mid 70's, I seem to remember there were several third-party contenders for S/370 memory expansion, Intel and CDC among them. I hadn't realized that MAI had gotten into that business...

Well, not a 1.2MB 5.25" boot, but I do have a 720K 5.25" boot. If you can set your system up to boot from that, I'll send along an image. You should be able to set up your 1.2M drive to handle it.

Just going by the OP:



Personally, if you want a capable CLI-oriented OS, I'd opt for MS-DOS. Easy to find support for with a wide base of applications. At least in early versions, not much...

I've been in similar disagreements with classical musicians who go for the "authentic" performance, using period instruments (or replications thereof). "That's nice and interesting but if you want...

Just pointing out that while I haven't run CP/M on "real" hardware in years, I routinely run CP/M programs on modern hardware. Works the same, only faster and less fidgety. My S100 systems have...

An emulator running on a modern platform is pretty darned accessible. Just saying... :)

That's only true, AFAIK, for the solder-tail TI units. I think that I remember that the wire-wrap ones are different--I'd have to dig in my stash to make sure, however.

I had a look at the files pointed to by NAPALM. It's for the Novastor backup package. Tapestar.sys is a driver for a DC2000 QIC tape drive.

Well, scratch that one.

Actually, it's a pretty smart move on China's part. If you want a nearly hack-proof platform, release no technical details on it and restrict distribution. Now that hacking has been nationally...

The Russian FTP indexers seem to be history, pretty much.

NAPALM is about the only decent one left, as far as I can tell. At one time Google had an ftp search capability, but that seems to be...

Have a look at the NAPALM ftp server (hint). (Google doesn't index ftp sites).

The SCSI tape interface is a standard ANSI X3T10 beast, so it's not difficult to write your own stuff if needed. I...

Again, the official distro has been in the works for a couple of years now and the proposed course of action is to install it in governmental offices, a relatively well-defined user community.
...

No, HGC and MDA will most assuredly not coexist in the same system. Both use the same I/O port addresses and memory address range. Of course, CGA and MDA/HGC can work together, but that's...

That's what I discovered ~10 years ago. Same for Chi Corp.

Fortunately, my only Qualstar drive (not that I use it much--at 6250, it's almost useless) is a SCSI unit, so generic utilities will...

The article refers to Chinese governmental installations. It has nothing to do with the civilian market. As China holds to an intensive surveillance approach for cybersecurity, this comes as no...

Do you (or anyone else) have any really Canadian-origin systems? (e.g. AES, MCM, etc.) Those would pretty much date back to the (Pierre) Trudeau days.

For the last 30 or so years, a system with a V20 with a repaired pin has been functional. I used a bit of phosphor-bronze wire--very stiff. I originally got the wire to convert SIMMs into SIPPs...

We could settle the C vs. F matter if the world would just convert to Reaumur. That 25F would be about -3.1Re.

That way, everyone would be at a disadvantage.

Mouser seems to have only a few in stock.

How about these from JDR

or

These from Jameco

Both suppliers are old-line hobbyist stores.

I used pins from TI gold-plated wirewrap sockets as prototyping board terminals. Just solder them in after clipping off the grabber ends. Honestly, TI sockets were some of the worst ever produced.
