content: 60Mhz tricky dicky branded (rebadged no doubt...).No probes, no power cable. what you see is what you get.Triggering isn't stable.Last time i used it, i recall some smoke escaping while it was left on to warm up, it was switched off for the last few years, only powered today to test while cleaning up (no smoke). Could be simple, could be involved, its free for someone to have a crack/play with.Pickup Northmead 2152, sorry i won't post.

Do any of the normal suppliers provide what you want?https://mouser.com/https://uk.farnell.com/https://digikey.comhttps://lcsc.cometcEven greymarket sources will do for this sort of stuff:https://ebay.comhttps://aliexpress.cometcAlternatively youmight want to buy from closer to home.NB "5V" leds are simply standard LEDs with an in-built resistor. Normal LEDs are easier to get and you can then use your own resistors.

content: There are lots of guides on the web for calculating resistor values for LEDs.At 5V: I'd just throw 1k at the problem and see if the LEDs are bright enough or not, then work from there. Most 5mm leds are rated to a max of 20mA, but I find even a few mA is enough brightness. Sometimes I even use 10K because I want them to be reasonably dim

content: QuoteGood question. Although I pay via cards, I note that I also have a bank account associated, yet when I get funds I still have to go in and manually extract them to that account. That suggests that the process of getting your funds out isn't automatic even if you associate a pukka bank account.So, I would suggest that you create a positive balance (send yourself some money, add it from your card or get someone else to be kind to you) and then go through the extraction process. Hard to argue with experience

content: The part number MN414100ASJ-07 is for the nine individual 4 Mbit DRAM chis on the sim, not the SIMM itself.The 30 pin SIMM is a Goldstar GT-3009, which is 4 Mbyte (with parity) 70ns. They are fairly rare as back in the day they were very expensive and had a very limited market as there wasn't much before Windows 95 that could make use of 16MB RAM, you had to fit them matched four at a time to 486 systems, and early Pentium era systems had 72 pin SIMM sockets, as did contemporaneous high end 486 systems.You should check if your motherboard chipset actually supports 32MB RAM. If you are unlucky, it may only allow 1MB SIMMS if all sockets are filled. It would be a pity to fit another four and find your usable memory capacity has halved!Google finds a few sellers but obviously, if any of our USA members has some they can let you have at 'mates rates' that would be preferable.

content: Thanks Ian.M!I knew when looking for the this SIMM memory that I had to get deep into the details, like you said, 4MB, Fast Page Mode, 9-chip, Parity, 70nS and that's why I wanted to look specifically for what was originally installed on the board. Sure enough too, you can see the GT-3009 printed on the PC board above.I have four of the 4MB Panasonic memory that came installed originally in bank 0.This Socket 3 GA-486TA motherboard from 1993 has two SIMM banks (0 & 1) with four slots each:https://arvutimuuseum.ee/th99/m/E-H/32006.htmI also read that the board will accept up to 128MB. The yellow dot represents the current configuration:I'm looking for four identical 4MB sticks which would bring the board's total to 32MB.Here are some other manufacturer's chips having the same specs:Hyundai, HY514100J-70NEC, 424100-70Texas Instruments, TMS44100DJ-70Hitachi, HM514100AS7Motorola, MCM54100AN70Toshiba, TC514100ASJ-70If anyone has a set for sale that fit these parameters, let me know

content: Hello,I am selling a Fluke 8840A bench meter.The case has some marks on the top (see pictures below), it is missing the handle and I glued the back plastic bezel in two corners (also shown in the below pictures) but, other than that, it is in good working order (to the degree I could test) and the VFD brightness is good as well.Asking price is £130.Due to the weight of this thing (I think it's over 4kg), as well as the relative fragility of the VFD while being transported, I would prefer local collection.If someone wants it shipped, I can do that and will look to pack the meter properly, but the buyer assumes the risk of the VFD being damaged in transit.Update:I recently received a similar meter which came in packed really nicely (thank you!), so I am confident enough I can now ship this one with minimal risk of the VFD getting damaged.

One (or better two maybe) times in a day at the same time perform quick ACAL and write down the values of CAL72 parameter together with internal meter temperature, all doable via front panel, will take a few minutes of your time.As the result (I hope) people may make a decision about meter's behavior. There is number of topics on eevblog where CAL72 is mentioned, so cool guys already wrote many words about testing.
