I only just spotted the previous posting in this thread. Has anyone else tested this? Has anyone else looked through ADVENTUR.COM to look for DI/EI pairs?

Very interesting to see the PromICE discussed here. Grammar Engine was founded by a friend of mine and when he stopped making hardware, he has given blanket permission to share information/files. I provided what I had to Bitsavers. Here are some photos and PDFs available online...

I just have the original (that I got from a shareware disk c. 1990) . I didn't see the 40-column version existed until just today. I'd love to look over a disassembly (rather than completing my partial one - I was just looking at the front bit of code, initialization and menu code because that...

I found the same thing with a specific version of CP/M Plus for the C128. Try grabbing a different version of the CP/M disk from zimmers. I found that one worked and one did not. It seems to be at the point that the application does a BIOS call to do console input to grab a character from the...

Hi. I'm the guy that found ADVENTUR.COM and added the RNDTST program and posted the collection to the IF Archive. I wish I had an answer for your question, but I can say that I have seen similar behavior with one version of CP/M Plus on the Commodore 128, but not a different (older?) version...

I personally spent several evenings in that Hell. All I wanted to do was to compile a simple test program (like "Blink") for the Pico from C++ source, *not* by uploading the pre-built TinyPython EF2 file and blinking an LED in Python. Part of the Hell was my own making - I intentionally chose...

That 1982 price of $10 per slide is why I later picked up a Polaroid FreezeFrame Video Recorder. It was only NTSC resolution, but I could make title slides on my Amiga and get a stack of images for the (incremental) cost of developing a roll of slide film (under $10 for 36-38 exposures at the...

Here's the lower board from the Dicomed box, the board with the RAM and the 7220 (and lots of '299s and '273s)

I don't know that a drill press makes a good rivet setter. Try looking at an arbor press. A small one shouldn't be expensive. If you look at a manual rivet setter you'll get an idea about what the dies need to look like. The big deal with these is the small finger that sticks up. In the...

I happen to have a foot-powered Stimpson riveter we used to use in at work in the 90s and 80s for attaching handles to our Qbus and Unibus boards...

Thanks for sharing that. I grabbed a copy (and found what you started from). I am not a Windows user so I may make a proper Makefile for this when I get that far. As of yet, I haven't reconstructed a working II+ or IIe but I'm closer as of this weekend (I picked up an empty IIe that should be...

Yes. Not much online about this product. I asked on FB and someone else said they had two of them, but no software or docs. I've worked out the pinout of the Apple card/40-pin cable 2-40 even GND 1 A2 ['373 pin 6] 3 D0 [Apple bus 49] 5 D1 [Apple bus 48] 7 D2 [Apple...

Greetings, all, I've recently had cause to go through all the Apple II stuff I have and this bubbled up to the surface. I got it from University Surplus quite some years ago, and even a recent Google search reveals my initial queries but no answers. Recent explorations reveal that it's a box...

Eric, I receive my notifications of topic updates to a Yahoo! account. Their spam filters snag the notices and label them as "Bulk E-Mail". Here's a header... X-Apparently-To: erd...@yahoo.com via 216.136.130.81; 01 May 2003 13:43:05 -0700 (PDT) X-YahooFilteredBulk: 64.235.234.245...

OK... moving on to one of my favorite machines of all-time, the PDP-8... I've had PDP-8s of one flavor or another for about 20 years or so. Back in college, I ponied up $600 for an RL8A and another $250 for an RL01 (with shipping) and so have had a hard disk on a PDP-8 for quite a while now...
