My name is tim lindner. I live in the San Francisco Bay Area. My main hobby is computer emulation. I relive my youth by focusing on my Tandy Color Computer and Mattel Intellivision.<\/p>\n
I work in the commercial printing field as a Digital Stripper. I like the way that sounds.<\/p>\n
I consider myself a computer programmer. I have worked on a number of projects over the years. I started my emulation career by forking the 6809 CPU core in MESS into a 6309 CPU core. Most people believe the Hitachi 6309 is just a pin compatible 6809, but it also includes a number of improvements. More registers, more instructions, and a mode that runs most instructions in fewer clock cycles.<\/p>\n
Then I started helping out with the Color Computer drivers in MESS. I rewrote the floppy disk controller to support reading of different size sectors. Added track read, and finally DMK disk image support. I did this so I could run my Diecom games without breaking the copy-protection. I also added 1 bit sound support so the heart beat in Dungeons of Daggorath<\/i> would work.<\/p>\n
Afterwards I became interested in the Speech\/Sound Cartridge. I wrote a brand new CPU core for the device, the TMS7000. In December of 2006 I ported a SP0256 emulation from Joe Zbiciak to work as a MAME\/MESS sound core. The SP0256 is really cool speech chip. In June of 2017 I finished the S\/SC emulation in MAME.<\/p>\n
One long term project I have for MESS is to re-implement the WD179X core. The current code is focused on being sector based, and I think a better emulation would focus on emulating a rotating disk. This was eventually done in MAME independent of me.<\/p>\n
Old Email Addresses<\/p>\n My first email address on the internet was akabar@aol.com, that was from around 1992 thru 1994. Then I got a Netcom dial up UNIX account and used tlindner@netcom.com. Netcom changed their plans sometime around 1996 and I had to change to tlindner@ix.netcom.com. I had that email address up until mid 2006.<\/p>\n My current email address can be discovered by taking the domain name of this web site and changing the first dot to an at sign.<\/p>","protected":false},"excerpt":{"rendered":" My name is tim lindner.
