here's a nice little TV. 7" round crt.

this capacitance meter looks like it wants to be controlling your air conditioner

old computers. how about that 2-in-1 floppy drive?

Tube❄️Time replied to Tube❄️Time

vicmodem and a commodore modem 1200

Tube❄️Time replied to Tube❄️Time

what did i buy? well, i bought this Micro Switch keyboard. 53SW1-8. i'll have to find keycaps. apparently it uses 2SW keycaps.

Tube❄️Time replied to Tube❄️Time

i picked up this Seagate ST-251N which is the SCSI version of the 251 drive I've reverse engineered. I haven't documented the control board in this one yet.

and i got a type 2 planar for an IBM PS/2 Model 80. this one is meant to run a 386 at 20MHz. i could use it to upgrade my model 80 which has the slower type 1, 16MHz planar.

(there's a whole story about the type 1 needing matched memory cycles and the type 2 not needing that)

Tube❄️Time replied to Tube❄️Time

it's missing a few chips and has some damage.

@tubetime Oh.

That's uh...

That's a crack. 😬

Tube❄️Time replied to Tube❄️Time

digging in my stuff I found a loose keycap. I wonder...

root42 replied to Tube❄️Time

@tubetime Weird place for the 7. Does it come from a keyboard with the numpad on the alphabetical keys?

Richardus replied to Tube❄️Time

@tubetime oww. Never seen a crack in a chip like this.

Abe the Honest replied to Tube❄️Time

@tubetime so that's what it is! A friend of mine gave me a motherboard very similar, noting that there was almost no estàndard conector. I knew it was an IBM but never looked into it further than that.

John Wilson replied to Tube❄️Time

@tubetime I think I had one of those, I wish I had the audio recording of that thing booting into DOS 6.22

@tubetime Hall effect? Honeywell had some nice kryboards in the 80s.

@tubetime Ooh Performa 630 aka LC 630 and Quadra 630.

@tubetime loving the "Z80 Inside" cards ... the popularity of older electronics based on a recently defunct processor is exciting.

@tubetime Given the magstripe - > Chip and Chip -> tap evolutions, there must be a ton of these credit card readers lying around.

Martin Rundkvist

@tubetime I still don't need much more processing power than those machines offered.

Osunderdog

@tubetime An old #micron PC in that lot. Brings back memories.

Those were heady days. Stupid heady days.

root42

@tubetime and it’s a Micron computer! I only know them from DRAM.

lopta

@tubetime I remember those! Save you a whole drive bay!

@tubetime The scary thing is that looks like the one I sold at the swap meet about 6 years ago. 😆 I really liked the re-purposed dimm type boards for personality.

VanillaSkunk

@tubetime huhuh I understood that reference, and I think I know which thermostat you're referring to. Even I did a double take.

Ed W8EMV :radio_tower:

@tubetime

I had one of these, that's a Z-158 if I'm guessing right. lovely systems, no motherboard just a bus connector to put all of the parts into. with a new PAL chip the memory board can take 256K DRAMs for a RAM disk, which was very exciting compared to running programs from floppies.
