Clock program for COSMAC Elf microcomputer with PIXIE graphics

by spacewar＠gmail.com

I've written a clock program to run on an unexpanded Elf with PIXIE graphics. It proved to be quite a challenge to fit it into 256 bytes, but I've now got it working, with two bytes of RAM to spare. There are 12-hour and 24-hour versions. I've released it under the GPL 3.0 license. The source code is in a github repository: https://github.com/brouhaha/elf-clock A text file containing instructions and hexadecimal object code is at: https://github.com/brouhaha/elf-clock/releases/download/v0.1/elf-clock-v0.1…

Cekit 8085 micro trainer

by jules.richardson99＠gmail.com

I picked up a Cekit 8085 microprocessor trainer last weekend, model MT-01. Google seems to be of no help - has anyone else here got one of these? There's nothing really specific that I wanted to know, but it's just odd that there seems to be no info out there at all about it. Some of the writing on the PCBs is in Spanish, and it says on the back that it was made by Cekit for EKI - but throwing that into the Google pot doesn't appear to be of any help. I'm not even sure how old it is. The CPU, I/O chip and some of the logic is dated 1983/84, but then there are a handful of Goldstar 74LSxx ICs with 90xx codes on them. It may be that Goldstar just didn't follow date code conventions, or it's quite possible that it really is that recent (and some of the ICs just came from much older stock). cheers Jules

> Is anyone confirmed to be picking this stuff up? I sent the person an email, never heard back. Ditto for one of the people here who said they'd sent the person an email - I sent them an email, asking if they'd heard back, never got an answer from them either. Noel

Via Mike Ross, but contact Greg with any questions! ---------- Forwarded message ---------- From: "Greg Bebermeyer" <bebergee at gmail.com> Date: Feb 27, 2017 4:44 AM Subject: IBM System/32 - web response To: <mike at corestore.org> Cc: Hi Mike, Maybe this is no longer relevant since I can't tell from the web page how recent the post is... I am selling my house and in the back of the garage is a complete System/32 that was working when I stuck it there and covered it. Much other stuff is in front of it so I haven't seen it in a while. It's free for the taking to anyone willing to come to East Lansing, Michigan and pick it up. If you aren't interested then it'll just go to the scrappers because I need to get the place ready for inspection. The junk haulers should uncover it in a day or two at which point I could take pictures. I also have a PDP-11/60, if you know of anyone interested. Same deal - free, come pick it up. The 11/60 main box has been stored in a dry basement along with two RL01 disk drives (in free standing cabinets, not rack mounted) along with a box of flat interconnect cables. It was used in a cardiac unit to run heart monitors and has an extra card cage full of interface cards. Also there's 3 PDP-11/34s in a rack in the garage as well. All this stuff has to go in about a week to 10 days, unless arrangements/promises are made and kept. If you're interested in any of this stuff, or could refer me to someone who might be, I would love for this stuff to go to a good home. Yup, I started with FORTRAN and 80-column punch cards. Thanks.

Able board on eBay

by jnc＠mercury.lcs.mit.edu

> It's one part of a DMAX/16. Oooh, good catch. I hadn't looked carefully at those faint images, I was just looking at the brochure which had the separate images. > Not nearly as cool as an Enable :). Yes; the ENABLE was pretty clever: it used an MUD backplane as an EUB backplane, to hold the ENABLE and stock EUB memory cards; both the CPU _and_ DMA devices were on the incoming UNIBUS, and the ENABLE could tell whether a read-write cycle was from the CPU, or a DMA device (if you look at the UNIBUS spec, there's just enough to do that, even without being able to see NPG), and routed it through the appropriate mapping, depending.

Able board on eBay

by jnc＠mercury.lcs.mit.edu

So there was an odd board from Able up on eBay: http://www.ebay.com/itm/311809552775 Anyone know what it was? From the Able product summary it looked a bit like an Interlink/U or perhaps an Enable - although the detailed chip layout didn't look like the illustrations of either. Anyone know? Also, speaking of the Able ENABLE, I've recently discovered more about it, and now understand pretty much how it works. Noel

If you manage to find something, please let me know thanks Andrea >I've got a photocopied user's manual in this mess somewhere (used for the "VR:" VT30 emulation in E11).
