rfka01 Senior Member Registered: 01/01/12 Posts: 159 Loc: Bavaria	I've taken apart a few machines to send ICs to a guy who'll try to read as many of them as possible. I've used this opportunity to take a few more pictures, and in some cases re-read eproms. The ITT 3030, a Z80 machine, was on the old "ROMs wanted" list ... unfortunately mine is not functional at the moment. This archive contains a few teledisk images, the character and boot roms, the docs I have and a few pictures.

robcfg Member Registered: 03/26/08 Posts: 93 Loc: Madrid, Spain	Hi, what kind of ic's are they? If I can read them and you don't find anyone nearer, I can read them for you and return them. That is, if you don't mind sending them to Spain Originally Posted By: rfka01 I've taken apart a few machines to send ICs to a guy who'll try to read as many of them as possible.

rfka01 Senior Member Registered: 01/01/12 Posts: 159 Loc: Bavaria	I've taken apart the machines from the "Requirements" thread, they're controller chips with internal roms like the 8741. Thanks for your offer, I'll contact you if he has any problems or ICs remain unread. Robert _________________________ NCR DMV- DEC Rainbow- Siemens PCD- ITT 3030-Oly People- Acorn A5000- Olivetti M20

rfka01 Senior Member Registered: 01/01/12 Posts: 159 Loc: Bavaria	Andreas, who's contributed to the M20 emulation progress, has dumped some more ICs from other PCs which I'm posting in the appropriate threads: This archive has been updated with the contents of the 8741AD graphics chip: ITT3030 To my best knowledge now all code should have been dumped.

I couldn't take no for an answer and poked around a bit ... the keyboard cable (it's fixed to the main case) had come just loose enough to malfunction.

rfka01 Senior Member Registered: 01/01/12 Posts: 159 Loc: Bavaria	Hi Micko, the system uses the Z80 PIO, a D8741 for keyboard, a character EPROM, 256KB of RAM (1 page on the CPU card, 8 on a daughter card), a MK3886 for serial I/O, 256 bytes of shared RAM, 2 timers and interrupt control, a WD1791 floppy controller and a VTAC 5027/TMS 9927 Video controller. I'm doing a quick translation from the system and user manuals that will contain a memory map.

Micko Senior Member Registered: 02/29/08 Posts: 307 Loc: Serbia	Thanks, that would be great. It's faster that way Also will probably first do it using old wd17xx core, to see how it boots and all and then add TD0 support for new style floppy.

rfka01 Senior Member Registered: 01/01/12 Posts: 159 Loc: Bavaria	OK ... here are the user and technical manual in German again, but I've added a partial translation of the parts that seemed most important to me. There's more on the MK3886 and the 5027/9927 if needed - I don't know if those are emulated yet.
