He learned to program on the 1000, eventually switching to the Commodore 64. He’s recently returned to the Timex/Sinclair fold. He’s considering making a LISP-based interpreter of Sinclair BASIC. - [Jim March](http://localhost/indiv/james-c-march/), co-author of [The Timex/Sinclair User’s Encyclopedia](http://localhost/book/the-timex-sinclair-users-encyclopedia-ts1000-ts2068-and-zx81/), told us about how he got into computers as a kid in the late 1960s and the Timex/Sinclair 1000 in particular, and how that led to co-authoring the Encyclopedia. Jim was also in the [East Bay Zilog User’s Group](http://localhost/usergroup/easy-bay-timex-sinclair-user-group-ebzug/) and he had several columns published in Timelinez. - [Stewart Newfeld](http://localhost/indiv/stewart-newfeld/) jumped in to chat with Jim about the best way to distribute his collection and also gave us a short history of his company, [Zebra Systems](http://localhost/company/zebra-systems/). - Newcomer Chris asked in chat about what he could use to program on. We recommended [ZEsarUX](https://github.com/chernandezba/zesarux) or [FUSE](https://fuse-emulator.sourceforge.net/). Tim Horner recommended [EightyOne](https://sourceforge.net/projects/eightyone-sinclair-emulator/). - Stewart asked about making the replacement 1000 keyboard (with tactile switches) emulate an IBM keyboard, for use with the emulators. [David Stephenson built something along those lines](https://www.zx81keyboardadventure.com/p/zx-key-support.html). - [Adam Trionfo](http://localhost/indiv/adam-trionfo/) asked about which emulator might do single-stepping, a feature helpful in debugging code. Adam is disassembling the Q*Bert cartridge. - [Johnny Red](http://localhost/indiv/johnny-red/), from Portugal, joined us to talk about [his website](http://timex.comboios.info/) and the [Timex Portugal](http://localhost/company/timex-portugal/) disk drives systems ([FDD 3](http://localhost/product/fdd-3-disk-drive-system/) and [FDD3000](http://localhost/product/fdd-3000-disk-drive-system/)). Johnny has had a website about the Timex computers since the early 2000s. We talked about the disk system and Johnny described the disk structure and showed us a version of [Fuse built with an FDD3000 emulator](https://sourceforge.net/projects/fdd3000e/) that can load disk images. He told us about [CPCDiskXP](http://www.cpcmania.com/cpcdiskxp/cpcdiskxp.htm), which can be used to read FDD 3″ disks directly with a Windows XP computer. - Adam gave an update on his [BackBit cartridge](https://www.backbit.io/); he only tested it 15 minutes before the meeting. He has also continued with his disassembly of Q*Bert and has made tremendous progress. - [Jeff Kuhlmann](http://localhost/indiv/jeffrey-kuhlmann/) gave us an update on his work towards making bootable binary images for use with the TS 2068 cartridge. He told us about [OshonSoft’s Z80 emulator](https://www.oshonsoft.com/), which he’s using to program and debug his work. - [Ingo Schmied](http://localhost/indiv/ingo-schmied/) told us about a 4 port I/O board he built for his computer using the Z80 PIO chips. - We got back to Jeff’s projects and referenced the [Third Party Software Guide](http://localhost/document/timex-sinclair-2000-third-party-software-guide/). - Stewart caught us up on his collaboration with Tim Horner. Tim has designed a circuit to allow connecting a ZX Printer/TS 2040 printer to an Arduino, with an ultimate goal of being able to print to either printer from a Windows computer. Stewart is going to make Tim’s circuit board available, when it’s ready. ## Youtube embed
