The only 8008x that I ever had that did NOT function at 500kHz was the East German 8008 copy. To be fair, maybe it did work but none of my 8008 machines have “strictly by the book” clocks and maybe it wasn’t as tolerant. I have at least two ceramic Intel -1 chips from Barbados that work in my...

I was told by a book-writing 8008 expert that by the mid-late 70’s date codes, most if not all Intel 8008’s could operate at -1 speeds (attributable to process improvements, not a die shrink or technology change, like from PMOS to NMOS). Of course, Intel would not guarantee this. I will test...

“But yeah, I guess my 8008-1 wasn't happy for some reason. No 800kHz for me then if I need to use my 8008 regular.” Oddly enough, I am building an expanded version of a Jim Loos based 8008 SBC and it can run at 500 or 750 khz. The only issue I’m having is that the reset circuit doesn’t always...

I looked into this a long time ago and it involved long discontinued and genuinely rare TI 75xxx series IC’s. To do this one-off with discretes or even opamps would be heroic.

I don’t have any “files” anymore, but, generally, here’s how I did it. Remember, I used Microsoft Paint, which definitely is not good for “mass production” of labels and it is pixel oriented, not vector based. I have tenacity in place of artistic skill! I based the label on labels that I had...

Digital Equipment (DEC) 1” paper tape, in boxes and a roll. You get: 3 boxes fan-fold, full. 1 roll, 100% full. In very good condition, stored in cool, dry place. I punched some recently and it worked fine. There isn’t a lot of paper tape available anymore period, never mind, genuine DEC paper...

I worked for a company that made ferros, they were great, especially with PCB capacitors. Not printed circuit board, Poly Chlorinated Biphenyls! They really would last forever. We had a ferro regulator returned under our 25 year warranty that took a direct lightning hit. The cap blew up but the...

Well, they aren't "mine", but here they are. I'm not certain that the life game is working but I haven't really tried to use it much.

"That smacks of "cheating". The 8266 is considerably more powerful than the 8008. At least on the C64, the drive processor was the same as that in the C64 itself." Well, true; this was expedient because I still have a few low-EPROM space 8266's lying around. But getting an OS into the 16K of...

Not much going on in this section, so… This is actually a continuation of an old thread that went off course into something different ( https://forum.vcfed.org/index.php?threads/4004-4040-projects.1244204/ ) Over the last year, I added some peripherals to Jim Loos’ 8008 SBC design, and...

As I recall, windows NT 4 post SP4 was pretty darned good and the first version that I thought eclipsed Novell Netware for reliability/usability.

I would hope for 4289 support in this project, configurable with some kind of a file. This has been a shortcoming of other emulators. I’m glad you mentioned that the 4265 is complicated because I found it amazingly complicated and I thought it was just because I was dumb! There COULD be other...

The few vintage printers that I have probably would be of interest to very few collectors. I would, however, find some way to make room for a Xerox daisy wheel printer/terminal using the HyType II mech, though. They were genuine marvels of their time and built like tanks. I repaired them for...

I may have seen a keyboard like that in an early Byte magazine ad (Meshna?).

Thank YOU!
