LJN Videoart Main Board. I have identified most of the components. 7805CSP is a standard 5v voltage regulator. EF6805R2P is an implementation of the Motorola 6805 microprocessor. EF9367P is aGraphics Display Processor produced by Thomson. The D41416C-15 appear to be 4-bit 16K DRAM chips. The TSGB01019ACP is sadly a complete unknown. The various "74" chips are generally known as "Glue Logic", used to connect between other components. T74LS04B1 is a Hex Inverter. T74LS373B1 is an Octal Transport Latch with 3-state Outputs. I'm not entirely sure what DM74LS374N is.

LJN Videoart: Note on internal construction and disassembly. Okay, when LJN made the oversized top piece that covers the comparatively small circuit board, they made it as one solid piece. I'm still not sure how they slipped the gray plastic piece in there. However, I now know how they snapped the tiny circuit boards for the buttons in place. They slipped the buttons' circuit board between The grey plastic button panel and the inner part of the white top shell. The circuit board then sat on pins from the white shell. They then heated the white plastic from the inside to melt the pins and hold the buttons' circuit board still. I think this was a terrible design choice, and it isn't just because it meant I had to dremel the case to get the button panels out.
Allright, just received a Ti486 SXL-40. An even beter upgrade processor for my Toshiba T5200. This is the 8kb chip that i believe can be clock doubled. This means that the old 386DX 20MHz will be screaming at 40MHz.
Texas Instruments Majestic Line Reshoot. I figured that I should take another picture of my calculators from Texas Instrument's "Majestic Line". I took the original picture back in June 2018, and I mentioned that I was just missing the Gould's Pumpulator to have a complete set of all of the Majestic Line members that were released in the U.S. Here we are over a year later, and I finally have one. The complete U.S. Majestic line consists of all of the calculators pictured here except for the four calculators on the right side of the bottom row. Those are members of the Majestic line which were not released in the U.S. There were some unique model numbers such as the TI-15 and TI-31. There were also minor tweaks, such as a Brazillian "Money Manager" with a brown case instead of black. Personally, I care more about unique model numbers, and I probably won't chase down small tweaks that cannot easily be searched for.
Second bit for the Apple 2c. The monitor stand and an Apple branded printer. I have 0 experience with Apple 2 computers, so this is gonna be a lot of fun.
First half of an Apple IIc haul. The apple 2c, monitor, extra drive, box of manuals, boxed set of finance software, full set of original apple 2c disks and a whole load of floppies and printer ribbons. I couldn’t fit the monitor stand and the printer in my motorcycles cases. So i’ll pick those up tomorrow. The computer also comes with the original box, which is a first in my collection.
And it’s in the Toshiba T5200. And even with the most ineffective settings turned on, there’s a nice speedboost. My testgame was Raptor: Call of the Shadow, which would really slow down when the shooting and explosions start. Now it runs a lot smoother, and it should improve with better settings. And it needs a heatsink, as these upgrade CPU’s run HOT🔥
2 Texas Instruments TI486DLC/E 33 processors in PGA132 format. These are upgrade CPU’s for 386DX motherboards and can give these older motherboards quite a boost. It should boost the performance of my Toshiba T5200 (386DX @ 20MHz) quite a bit. The other one will be tested in my IBM P70, also a 386dx @20MHz. These are the 1kb cache memory models without a clockdoubler. I’m still searching for a SXL 40 or SXL2 50, which have 8kb cache and a clockdoubler.
New project just arrived. An Advantech PPC123. I’m going to try to use this as a Win XP computer. It comes with almost every port under the sun, including a game/joystick port. But... ctrl/alt/del to log on to NT, thats a problem with no keyboard. Touchscreen works though
After much searching, I now have a presumably complete collection for the Mattel See 'N Say Video Phone (1989-1990). This is an obscure VHS-based console, and possibly the most obscure piece of my collection. I say "presumably" because I have never seen an official games list, and all I have is the box with a picture of a stack of four VHS tapes.
Battle Of The Tapes! Not many movies got S-VHS releases. Now that I have an S-VHS VCR, I want to see how much of a difference the "Super" part made.
Something a bit random. Found this on Ebay, I really like the concept. It’s a 3” CRT from an old scope, used as a clock.
How To: Capture Video from the "View-Master Interactive Vision" VHS console (or how to get it to display on a picky TV)

Well then... nothing of note, easy machine to work on. The drives are going to be a pain to get to so i hope they’ll just work. Smoke test past i guess, full ram, self test all passes. Took the little Varta battery out, it hasn’t leaked at all, but is will eventualy.
Just picked up an Olivetti M21 personal computer. The outside is in pretty good condition, but it’s an untested attic find. So i will have to check some things inside, clean the drives and do a smoke test hopefully tommorow.
The complete "Wedge Line" from Texas Instruments. This was the first family of scientific calculator from Texas Instruments. The line began around 1972, and it apparently ended around 1975. The SR prefix dealt with the slide-rule, the tool that TI was trying to replace. Several early scientific calculators from TI use this prefix. There were three variants of the SR-10, two variants of the SR-11, and the singular, rare SR-16.
Complete set of Cougar Boy handheld games, All fifteen of the Megaduck games that were released under the Cougar brand in Brazil. Seller claims that all of them except The 4-in-1 are CIB, as they are NOS from Cougar factory. 4-in-1 was always bundled with the console, so no box there. I have seen a few Brazilian eBay sellers with full sets NOS lately, so it looks like there has been some warehouse inventory liquidation. Word of warning, though. I had these shipped from Brazil to US, and it took about a month.
2-XL Tape Collection as of June 29, 2019. I have 24 (out of 45) of the U.S. 8-track tapes releases from Mego. I also have 6 (out of 44) of the U.S. compact cassette releases from Tiger. I dont have any non-U.S. tapes, such as the Mexican and French-Canadian 8-tracks or the compact cassettes that were released in Germany, France, Italy, Spain(?), or the U.K.
Pop Station Watch! Apparently this was released in the Soviet Union in 1988. I already bought one in a different color (of course), so I figured I would let people know about this one.
And here is "Alien" on the Watara Supervision running on real hardware via the TV-Link upscaled to 4K. Colors are inverted and a border is generated by the TV-Link.
