A new addition to the collection and a new project. An Apricot FP portable. It has some diskdrive problems, as it just wrecked one of my backup MS DOS 3.30 floppies. It came with a case and technical manual, but sadly no disks. And i think i read somewhere the F series disk format is ever so slightly incompatable with standard IBM 3,5 inch floppies. Ah well, challenge accepted i guess
🤯 The Mac Portable just booted from a harddrive, not sure what’s on it... this machine has been such a headache to get going. (It pretty much died again after i got it to boot from floppy last week orso). I’m not sure it’s really stable yet. But this is something.
She Booted!! Which means i have a functioning Mac Portable. This is from floppy, not the harddrive. But, i can’t believe it’s working. A happy mac There are some weird shrieks coming from the speaker, and this screen has a line in it. So some work still to do.
Another Mac Portable joins my collection. And, as with all “affordable” Mac Portables, it also doesn’t work. But according to the sellers pictures this one at least goes into a “sad mac error” state when turned on. And it has upgrades! A modem, ram expansion and screen backlight (which was not standard on this machine). I hope i can get this one going, even broken ones are quite expensive.
Complete (U.S.) Exactra line of calculators by Texas Instruments. All of these were released in 1974. The handhelds were intended as a low-budget line. The Exactra 19 in particular was specifically designed based on requests from the University of Ohio for a cheap calculator, so these may have all been targeted at college students. The desktop unit is the odd one out. However, it sold for $49.88 in 1974, which was only slightly more than the cost of the Exactra 20, which was $39.88. The Exactra 19 cut costs aggressively by design, and only cost $16.30. I haven't seen prices for the 21, 22, and 23. It seems strange to me that Texas Instruments hid the company name on the back and referred to them as "Exactra" rather than "TI". The Exactra 19 and Exactra 20 apparently got a European release as the TI-1900 and TI-2000. However, these are quite rare. The TI-1900 is so rare that I have never even seen a photo, and I have not seen a TI-2000 for sale yet. Maybe this line will have a family reunion some day.
I just upgraded my retro setup with a 19” Dell Trinitron monitor. But man, are those things big and heavy, it barely fits on my desk.
LJN VideoArt complete collection. Here are all nine games released for this system.The games were in clear clamshell packaging with the manual cover serving as the front box art and the manual back serving as the back box art. All you got was the cartridge, the manual, and maybe a flier advertising the games. Thus, all of my games are CIB except "My Favorite Doll", which is loose. The generic "Activity Cartridge" was bundled with the console, and I don't believe it had a manual or was ever sold separately. Now, does anyone know where I go to redeem my "VideoArt Proof of Purchase Points", or remember what they could even be redeemed for?
After a year and a half of tinkering, searching and probing around i’ve finaly jury rigged my Mac portable into showing a sad mac code with matching sad chime. This means that most of system should be working, but the power management isn’t driving them. So, maybe... who knows, it might actualy boot someday...
A moment of late 70s/early 80s weirdness from Mego. These cartridges are both called "General Information", have the same label, and are copyrighted 1978. Thus, they should have the same content, correct? Nope. In 1978, Mego released "General Information", as the first cartridge for their 2-XL robot. Then, in 1981, they recorded a second version of the same cartridge (not to be confused with "General Information II" and "General Information III", which were different programs with different labels) with major content changes. It now contains two programs instead of one, an interview with Benjamin Franklin, and 2-XL's theme song. The second version is rarer, as it was released the same year that 2-XL was discontinued. However, for whatever reason, Mego never changed the label or copyright date. The only way to know is to listen to the content. As far as I know, the slightly different blue color and the lower placement of the label are down to quality control or sun exposure, and they are irrelevant to the contents.

The Complete Texas Instruments TI-1600 Line from 1976. These calculators were produced in an effort to slim down existing Texas Instruments calculators from "hand-held" to "pocket-sized". The main obstacle was the VFDs ran on 9V batteries. As such, Texas Instruments had to commission the French company SAFT to make custom 9v batteries. The circuit boards are shaped like a block-letter "C" to allow the battery to sit next to them to make the calculators as small as possible. This line was discontinued when Texas Instruments released their first LCD calculator, the Ti-1750, in 1977. The lower power consumption of LCD allowed for the use of smaller button cells, which allowed for calculators even slimmer than the Ti-1600 line. None of these are working. They may not be able to draw enough power from only the adaptor, and the custom batteries are long dead. There may also have been battery leakage.
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🔥
