Before the 6502 came out, I had access to Tektronix catalogs, and definitely wanted one of the calculators.? So I found a source of surplus chips, all TTL, and a wirewrap board (sadly, all 16 pin/14

Thanks for confirming that, Global Test Equipment in Downers Grove have them on their website for sale, looks like I will get one from them, cant find one in the UK for sale

I had a wirewrapped Apple motherboard. I built a Heathkit H-something monitor and used that system for a couple of years. The Apple motherboard was wirewrapped as a sort of joke or something. I ended

Aha.? No Amigas. Clone apple ][ motherboards and clone IBM PCs until laptops somewhat took over. Harvey

I had one for my Amiga. DaveD KC0WJN Thanks for all the fish. ============================== All spelling mistakes are the responsibilty of the reader (Rick Renz, STK, ca. 1994)

Yep. Also, build the code so that there is no address 0x0000. "Base page 0" has a non-zero address. Basically, adress zero doesn't exist. This was a long time ago. Sheesh. DaveD KC0WJN Thanks for all

Some things I've found while working through the front panel controls section of the manual: Scan Width - #6 "turn scan width per div to 10mhz", result "LO Feedthrough, 30mhz signal, 2nd harmonic". I

... and use a language that reduces or eliminate the possibility of NULL or wild pointers occurring, or if it can't manage that, at least has the courtesy to tell you that you have screwed up.

I never found any Modula-2 compilers.? I looked at what was out there (circa 1980 or so) and I got what would work on a PC for free. Strictly low budget (and still, in a way, am). Harvey

and tests for null pointers................. Write paranoid code. Harvey

Pascal was originally intended to be a "teaching" language only and was never intended to be used commercially. Modula-2 was supposed to fix that. DaveD KC0WJN Thanks for all the fish.

Yeah, I got eventually. As team lead, I was responsible for code releases. It amazed me how many null pointers existed in the code. Apparently I wasn't the only engineer who didn't understand

I agree, I've used a couple of SP200s for many years. They are fantastic systems for general-purpose soldering, fine-pitch surface mount, and rework tasks. -Dave -- Dave McGuire, AK4HZ New Kensington,

Hi Jeff, thanks for reply. The switch is in the correct position. The display just reads 000020 and blinking. No matter what front panel change is made, the display remains the same. As i said i havnt

Hello all, My HP8563E is showing some peculiar behaviour. It sweeps OK to about 2.9GHz and then sporatically sees some frequencies. Below is an example of a 4-6GHz sweep. Has anybody have got an idea

Nope, Borland Pascal, then Delphi. It is possible to break the linker in Borland Pascal. Harvey

Pointers are relatively easy, if you can get the idea that it's a "look over here" kind of thing.? Given that, you can say "look over here and get me what's there" and then "here" when something

Yeah, I completely understand that. DaveD KC0WJN Thanks for all the fish. ============================== All spelling mistakes are the responsibilty of the reader (Rick Renz, STK, ca. 1994)

PS - I didn't run into EMACS until I was transferred to STK in CO in 1991. DaveD KC0WJN Thanks for all the fish. ============================== All spelling mistakes are the responsibilty of the

Sheesh. TECO. You are hurting my brain. We had PDP-7s at the first engineering company at which I worked in '77. Advanced Electronics Development. We designed and built prototypes of various machines
