I've not heard back from Gregory, he's probably busy making TIPI's after his awesome demo Saturday at the 38th Annual Chicago Fair. (I went to the very first one at Triton College) I think I have an account created and the files loaded. It looks like it will be less then a hundred dollars to roll the dice on this one. If I don't hear back from Gregory, I will place and order and put a note up on this thread when they are in.

fwiw - Looks like that book has been on the cyc since 2017, the dsk file since 2015 Canonical Path: cadd>cyc>books>stevedav>moleswor>introasm>introasm.pdf

Disk of Horrors, Big thanks to blackbox for putting this out there for Halloween enjoyment! I few notes, I ran this on Classic99, setup was TI Disk Controller, automap Disk1. HORRORA.dsk <> DSK1. HORRORB.dsk <> DSK2. HORRORC.dsk <> DSK3. Everything seemed to run fine, the only time manual intervention is needed, is when you choose option A. You will be asked: Insert Disk C into Drive 1. Just do a pull down of disks, in Classic99, remap DSK1 <> HORRORC.dsk and press Enter

how is keyboard and joystick input on these devices?

Toucan, Interesting question. I know the cassette save a load commands in4A are pretty well documented, is it is possible to compute the amount that can be saved per minute of type. While saving as many bytes as possible was a goal, from interviews I later did with TI engineers, reliability was probably even more important. Also, mildly interesting to anyone playing with cassettes, I'm playing with a machine called a Z88 Cambridge, and have been following the adventures of company - not CCL - that made a cassette interface for the Z88. Two major problems they bumped in to hard was many records had automatic gain control, which after listening for a few seconds would decide to either set the line for blast, or ignore the incoming signal all together. and some of the units didn't have enough power to work reliable. The said a good rule of thumb was use a recorded with 3 or 4 batteries, or even better, always leave it plugged in. Now, one missing piece, back in the early days or the Huggers Users Group. A lot of cassettes where in play. The hit rate of read back was pretty good as long as it was the same record and tape and was plugged in to the mains (best luck went to GE's Computer Record and TI's own unit). Then it got dicey - with one exception. TI pre-record tapes almost always read back. It would be real neat to pump the person in charge of producing tapes for sale, the quality control they went through to make that happen!

Hi ArcadeShopper, are you interested in doing a group order? Or are the numbers to low? Thanks, Dan

Below, is a picture from 99er.net of a TI-99 in handheld form. Has anyone done a TI-99 handheld lately that they like?

For your Thursday evening reading pleasure. I stumbled on this document while doing a search... PL/99 a mid-level programming language. https://scholarworks.wm.edu/cgi/viewcontent.cgi?article=4122&context=etd

Hey, Back to the fake chip video... I have a question. One of the techniques that was used to quickly identify a fake, was to test for resistance between pins. I guess going back in time, your biggest worry was the 'pulled' chip you got might have been dead when the equipment was surplussed. He brings up a valid point, you don't know what you are going to do to the rest of your chips it you plug a cable modem chip in to your 9901 socket! 😵 So is checking resistance a good ideal? You can't explode a chip with a meter can you?

Matt, Another quick question, arcadeshopper said this program no longer needs tipi. What's the requirements for a non-tipi, no Finalgrom system? Thanks!

Hi Arcadeshopper, I see no way to edit topic!

I purchased a http://www.2600-daptor.com/ I've been hesitant to mess with joysticks and pc's as it seemed unfamiliar and uncharted territory... Fortunately, there is good help to be found on the above website. So I plugged in the -daptor and an old Atari 2600 joystick. I tested with joy.cpl. Then, the moment of truth, I started Classic99 and TI Invaders. Everything worked like a charm. Thanks Tursi and -daptor man!

Would you be interested in a group order of Jefimatt's keyboard pcb?

So there are many different level's of 'build it yourself' difficulty levels. There are heathkits that have instructions, all the parts, etc.. you apply solder and check connections and done. With the keyboard, getting a printed circuit board made - easy (after it's been designed of course!) The keys don't looks like standard cherry key/switches that can be ordered. The connection from the keyboard to the tomy - is that a standard part, or does something have to be McGiver'ed? Then at the end, does the keyboard screw in or clamp in to the same place, and the same way as the original, or does the case need to be modified?

Jeddimatt42, Is the keyboard pretty much a drop in replacement - or does it require a lot of work?

A good pic here: Jeff White and I put together a similar device for testing and debugging.. VDP+XTAL+32K of Static Ram - of course half the ram was wasted, and signals you didn't want you could snip of off the wire wrap socket. So yea, those parts, wirewrap socket and a proto board.

The reason I posted the poll, is I wanted to get a feel for how many people use a source code control program (personally or professionally). Phase two, I'd like to find a number of people who would like to participate in writing a small game. That would serve as a proof of concept, of joint TI collaboration. The not fully formed plan would be something like this... Each person gets assigned a small section of code. We jointly check code in and out. To keep it simple, something that uses text-ish code - basic/xb/assembler. Dev's would be able to pick an engine - something that uses files in a directory would be great. A few simple tools might be needed for file transformation. For far to long, TI development has been lonely work. Beery Miller, tried to spur joint development by making MESS images available of his current development with tools and source code, that was a great advance. But I think now, many Dev's would like to (and DO!) break out of the dev environment presented by a TI or Geneve, where the TI and Geneve just become a target. I know I'm a very big fanboi of VS Code with language specific plugins. But this is a topic for a different post!

I'd like to see how many folks in the TI Community use github, either for personal or professional use.

If you are going to fix RAM, may as well do the upgrade!

Every time I see a 32K ram on the 16bit bus, I wish Gary and Don had finished the Accelerator, or I had box full of Top Radio Supply - 16bit boards to sell.

The creation of this sub board, energized me to go pull the tub of Tomy stuff that's been shuffling around with me for the last 30 years. I found: 2x Tomy Tutor's. 2x Tape Records - does anyone know if these use belts? 2 Joysticks, a set of paddle controllers, The two recent modules produced by Klaus Sommer Cartridge Jungler ---- I think Barry Boone (Aka The Master) ported all the Tomy games to the Geneve - which having all that would be pretty cool. Misc Documentation, some original housed at Calvin.ptloma.edu/~spectre by Cameron Kaiser, unfortunately, the wayback machine captured nada, but it looks like the owner kept everything and moved it to: https://www.floodgap.com/retrobits/tomy/ plus lots more! Not bad, for a mis-spent youth of going to computer shows and Goodwills. Something a little more interesting for your reading pleasure is the different levels of oxidization that can occur...

Klaus Sommer - I picked up a couple of his original boards.

So, yea for dfm - it started on the 990's and of course is very similar to TI-Writer/Editor Assembler editors. I think you have the heritage of later versions of dfm figured out, Gleen took it and made it available for TI and later HPUX systems along with ISAMATION. Larry Kroeker made a PC version available, at one point, I think Larry had a proto-windows version going. I also think Larry has passed. In the past, TI was very pragmatic about licensing. So I imagine it was as easy as say Larry talking to someone in management along the lines of: Larry: Do you have any plans of selling dfm in the PC market. TI: No Larry: Do you mind if I do? TI: No, but we get 2% royalties and maintain our original copyright.

Some thing like on topic... If you ever used DX10 or DNOS - you probably also used Df-Show, now a gentleman has rewritten that from scratch and made it available for linux. https://github.com/roberthawdon/dfshow I also wrote the company called CSI - they used to see DF-SHOW (with editor) for linux and hpux, I asked their general information email address if they would be interested in releasing that to open source.

How do you pack your cc40? I have a case I made in the 90's - It started life as an old cassette tape box like: https://www.ebay.com/itm/12-Cassette-Tape-Storage-Box-Carrying-Case-Faux-Brown-Suede-Black-Vinyl-Trim/163906644422?hash=item262998e9c6:g:KHYAAOSw74RdofmQ (Purchased at Radio Shack) I pulled the cassette racks out and custom cut three pieces of foam bottom, middle with the cut outs and top. I was able to fit in the cc40 and a power adapter. But - (everyone knows pelican cases $$$$) - I stopped by harbor freight and they have their own line of cases called Apache, and I was thinking I could make a pretty sweet cc40 carrying case out of one of those.. But now I'd need to fit - cc40, power adapter, and a Hexbus drive!
