Nice effort--and the yarn is an interesting touch. . .

The Alex Kidd demo will work on Red boards (using a 27C040 chip--512Kx8), on a Blue UberGROM board (using a 49F040 or a 29F040 chip--they are both 512Kx8 chips), or on a Yellow board (using a 27C4100 or a 27C400--note that both of these are 40-pin chips, and a lot of programmers won't program them as they are 16-bit chips that can downshift to 8-bits). One note on EPROMs: an EPROM tells you how many BITS it can hold--but your computer uses BYTES. Because of this, the overall capacity of the chip needs to be divided by 8 to figure out how much capacity it has in system. Some sellers do that math for you already (i.e., 64Kx8 is a 27C512 chip)--but always look for the x8 value when checking chip compatibility for the program you are burning.

And it appears that the second seller there is down to his last 13 E/A Cartridge sets. . .at only $47.99 each plus $8 for shipping. The manual is online and the cartridge is available as part of the XB 2.7 Suite--with a total cost in the same range, but the XB 2.7 Suite delivers soooo much more. . .

I'll have the boys do some experimentation with the game in the Games cartridge and see if it duplicates the odd behavior. . .

Some of them also have a standard serial connection on the back. . .so you could connect them together that way too using an Ethernet tunnel (Comtrol makes some nice devices to do that, but they are about $300 each and you need one for each end).

When looking at the picture in Photobucket, do not try to right click and download the picture. You will get the problem you've identified, Schmitzi. Instead, click on the Gear Icon and then click the Download selection from the dropdown. Note that the only two permissions you have to give the site to view the pictures (using No Script in Firefox) are photobucket.com and pbsrc.com.

I'd go with the screws--they introduce fewer problems in the printing process and in user assembly/disassembly activities.

I have something in the vicinity of 300 of these shelled boards sitting around now. . .It is interesting to look at how many different runs of boards get into some specific cartridge types.

You can use the Silent 700 as a nice standard terminal to access a minicomputer or old-school mainframe. I've seen them sell for between $50 and $200, depending on a lot of factors (submodel, condition, etc.).

I haven't had much playtime at all this week--vehicle maintenance got in the way. . . TI-99/4A Crossfire: 35 minutes (on an original physical TI cartridge no less--the only one I know of in circulation)

You are correct, Ciro. . .Rieti-Citta Ducale it is. I always mixed that one up for some reason. . .

Definitely something worth doing the Happy Dance over! Congratulations! :)

I bought this disk from Asgard back in the day. . .

You should be able to do that with a Myarc controller as well, Marc. I have one of those in my regular system. . .later versions of the Myarc DSR will format either type.

It is definitely neater than mine is right now. . .

I also seem to remember that on the 110V ones, the cables are always permanently attached--and the 220V ones had the connector like you have because they needed to be shipped with cords appropriate to the country they were to be used in.

The serial numbers and date codes won't tell you much at all on this one. All of the ones I've seen have been pretty mixed up. I swapped out the only 220V power supply board I had in one of my sidecars with a 110V board Gerd Weissman had in one of his sidecars before I left Germany. Otherwise, I could verify with the parts on the board, as they are the same power supply boards in all of the various sidecars. . .

It has a TMS9995. I have two of these. F18A chips work in them too. . .

The capability was later combined with the Terminal Emulator module and implemented as Terminal Emulator II. . .

Acadiel actually made the STL files I have now, so I don't have the capability to make variations (yet). I'll have to get some design software to experiment with before I can definitively answer your question, Toucan.

I have STL files for cartridge cases. The folks at the Faire saw what the results look like when done on printers at Shapeways. I might want a bunch of these, Toucan--especially as this is a much better price-point than Shapeways offered me!

If you look to the Formorall schematics for the PEB, you will find that you just need to move a couple of the wires from the power transformer in the PEB to some different positions on the jumper blocks to switch the push button PEBs to 220V. It would also be a really good idea to replace the slo-blo fuse at the back of the PEB with one rated for half the amperage at 220V too. I made these changes to a couple of PEBs while I was in Germany. . .and they work fine.

Note the typed label on the console. . .it shows that the system was the personal property of the named individual and that he was working in a government office. That type of sticker was pretty common on personal property in government offices back then--and they were to keep the property "personal" as failure to have then properly marked meant you had just "donated" them to the government without compensation. Of course, even with the labels, if you did any of your work on them, they ended up in the same "donated" status, as now the accomplishment of that set of tasks was dependent upon the presence of the formerly personal property.

You actually have a pretty early one--that is the last week of February (Eighth Week), 1980. That's a really nice find, as it is the first US machine I've seen from that specific time window. Most of the machines built in the beginning of 1980 went to Europe and had external power supplies with a DC output, an internal speaker, and a volume control slide in place of the Solid State Software badge. Many thanks for the data!
