I built one myself about 6 months ago using Veroboard, Diodes and a pair of 9-pin d-type connectors. It cost close to your $15 limit for the parts alone and that was WITHOUT buying a project box to place the completed converter into. If you factor in a person's time to solder these parts together [30-60 minutes?] and postal charges, I doubt you'll find anyone here willing to put the work in. Your best bet might be to search eBay for a pre-owned one. They do show up on there occasionally. If I might make a suggestion though? Rather than set a hard cash limit for how much you're willing to pay (which could be misinterpreted as pushy or impolite), ask around here for a used one. I'm sure someone within the AtariAge Ti community will have a spare they'd be willing to part with and I wouldn't imagine the cost would be much greater - and most likely cheaper - than buying from eBay.

That's the mod I did. IIRC, it can be done without removing the case from the modulator. On my current HD TV, I get no picture at all but the same modified RF modulator gives a perfect colour composite picture on my Commodore 1701 monitor. I'm convinced modern TVs aren't as receptive to signals from old computers as the TVs released around the same time.

Lotharek sells via eBay and via his lotharek.pl site. Both products are the same and made by the same person. Compare both options and work out which is cheaper including shipping. You're getting the same hardware but only you can work out which method proves cheapest. If others are selling HxC, quality may differ but only Lotharek designs and builds Lotharek products. In the past, I've bought from him via eBay AND directly from his web-site. Sometimes P&P worked out cheaper on eBay, sometimes cheaper from his site.

Somehow, I can't imagine it'd be quick enough for the emulation to work at full speed under wine. Could the code (for ti-99sim) be recompiled to make more efficient use of the new ARM CPU on the Raspberry Pi 2? I notice there are Make files present. It would be nice to have the extra grunt of the Pi-2 behind this. I've just unpacked ti99sim-0.0.12.armhf.tar.gz on my RPi2 and the console version runs without reporting missing dependencies but complains about missing ROMs.

I had a Component cable from RetroComputerShack but Ian has since withdrawn this item from from his shop. I've modified my PAL modulator, picking up two points from inside to provide Composite output. I use my modified modulator with a Commodore 1701 monitor. Depending on your modulator (Aluminium or plastic), the modification differs slightly. The plastic modulators require addition of a few electronic components whereas the (older?) Aluminium one requires only soldering a pair of phono cables to a few points inside the case.

TBH, I'm not sure without looking it up online. I've booted my C128D with CP/M just to see if it worked but beyond that, I've not investigated further.

IIRC, CP/M was restricted to 64K max. Any additional RAM was usually used a RAM-Disk (as was the case in the Amstrad PCWs).

Commodores on a 1701 via chroma/luma cable, everything else on a Philips 8833-MKII via RGB. Poll needs updating to include an RGB input option. I couldn't vote, as I couldn't complete the survey accurately. No RGB on Atari 8-bits but others, yes. Atari 8-bit via Composite into SCART on 8833-MKII.

Funnily enough, I STILL own a Tandy 1000HX. Lovely keyboard and you gotta love MS-DOS on ROM. Did anyone ever release a later version on EPROM? IIRC, the version in mine is something like 2.11.

Few (if any) other micros at the time allowed the user to daisy-chain an extra CPU (via "The Tube") for extra processing power. Be it a second 6502, a Z80 (for CP/M) or even an 80186 in the case of the Master 512 (for partial PC compatibility). I'd have loved to work for Acorn at their high-point, even if only as a cleaner.

I asked a retro-computing friend only last week, if he could choose a single micro-computer to keep from his collection, which would it be? After careful consideration, we BOTH agreed ours would be a BBC Micro, despite NEITHER of us owning one back then. My personal path through computing went thus: ZX81, Vic-20, Spectrum 48k, Spectrum 128K, Amstrad PCW 8512 (along with an Amstrad 2086 PC), Atari ST, Commodore Amiga A500 before moving to a home-built 486 SX/25 PC and then to Mac. I bought my first (RetroClinic refurbished) BBC Micro about 5 years ago. Acorn certainly knew a thing or two about designing microcomputers. The Acorn BBC range had the best version of BASIC on any micro at the time. How many others allowed the user to include in-line 6502 assembly language, inside a BASIC listing? Most BBC Micro games were great but a few ports were lacklustre. The ACG/Ultimate ports definitely paled in comparison to their ZX Spectrum originals. Jetpac on the ZX Spectrum is my all-time favourite game on ANY micro but if it weren't for the BBC, we wouldn't have had ELITE! IMHO, the closest US equivalent to the BBC would be the Apple II. Both were infinitely expandable and featured heavily in their respective country's educational system (for very good reason). I've lost count of the number of times I've watched Micro Men. Yes, it features a little factual artistic-licensing here and there but a good programme nonetheless.

Looks like someone has this all figured out (though I'm not keen on his choice of description. "Upcycled"). https://www.etsy.com/uk/listing/181223834/texas-instruments-ti994a-usb-keyboard?ref=shop_home_active_5

I've seen cross-compilation instructions somewhere online. Maybe that would improve compile-times? Let's face it, the Pi isn't supposed to be in competition with a full-fledged PC (though Microsoft are supposedly offering Windows 10 for free on the Pi).

The Raspberry Pi 2 was released just yesterday. Now with a quad core CPU and twice the RAM. Wonder if this will improve matters?

Happy to be of service and glad the solution was so simple. As I only understand "simple", I guessed I'd throw in my suggestion and see if it helped.

Could it be an XB program which is auto-loading on startup? Do you have a disk-image mounted in the drive 1 of the nanoPEB? What happens if you hold the key down after selecting A, while XB loads (to skip the auto-boot)? I seem to recall there's a way of booting XB from the cart without the nanoPEB attached. Have you tried this? Do any other programs load and run? What about the games? Is XB2.7 the only problematic program? If the programmed ROMs have verified, I can't imagine they're the source of the problem unless the ROM images themselves have become corrupted. Edit: As you said in your post (which I clearly missed), the other programs you've tried seem to work correctly, so I still can't imagine there's a problem with either of the ROMs.

I know they're popular in the UK, further North than I am (Newcastle and Scotland) but I can't think of a worse thing to do to a Mars Bar. Frying them must make them taste horridible™. I love to FREEZE mine in summer and cut the into slices instead (so I don't break my teeth or bite my tongue, trying to bite them).

I was thinking of chipping in, but I think this thread has already been de-railed. (I'll get my coat). I think the Atarisoft titles are quite playable but just imagine if the programmers knew then, what some on these forums know now. How much could the likes of Rasmus have earned as a programmer back then. He'd have been the "Ultimate Play the Game" of the Ti world!

Ooh, I remember playing Fire Galaxy on the Vic-20. A Scramble-like game, IIRC. I liked most of the Anirog games when the Vic was my only micro.

Heh. Without reading the text, I thought it *WAS* a PET screenshot. Maybe a PET port to the C64? Ugh!

4 x Hitachi HM6116LP-3, so definitely a RAM expansion of some design. If this one fits on the side port, we could do with someone re-engineering and selling something like this via AtariAge as a companion for the new multi-carts. Needing a PEB/nanoPEB plugged in just to use them can be a PITA when your Ti-99 isn't permanently set up.

In my experience, chains wouldn't have stopped most 80's kids in Manchester anyhow! I've lost count of the cycle-chains I've seen still locked to posts around the city, with no bike in sight.

You need to have a word with Ksarul. http://atariage.com/forums/topic/233535-quick-tutorial-on-cartridge-pcbs-needed/?p=3148071

An adaptor is available for the USB GQ-4X Programmer. The ADP-054 adaptor is supposed to work with 16Mbit EPROMs including the 27C160 though it's not going to be any help to growing the number of TL866 owners on here. This (very wobbly) adaptor would probably fit the TL866 but without checking, I'd assume the TL866 doesn't have firmware routines to support the 27C160. It's a pity really as the 27C160 EPROMs are cheaper and more readily available here in the UK than the ones used in the 512K carts and the TL866CS will also program Atmel 1284s out of the box. It might be a while before I can splash out on yet another programmer and adaptor. I'd prefer to program my own rather than rely on others to do the programming for me.

This might be a little late if you've already ordered but you'll get a clearer picture using SCART instead of composite (assuming your TV has SCART - it should if you're in the UK). http://www.ebay.co.uk/itm/Atari-ST-High-Quality-RGB-GOLD-Scart-AV-Lead-Video-Cable-TV-Lead-2mtr-/250978089310
