Shouldn't it be possible to get an NXP MC7448THX1267N to work in there? Note it's a lower power part bin specifically for that use... the 1400-1700mhz parts are higher power even at idle/sleep than this chip. Looking at the datasheet if using 2.5V IO, the IO pins can tolerate 3.3v maximum, it...

There is an open source implementation of Ethernet over SCSI http://ipoverscsi.sourceforge.net/ it's for Linux 2.4 but that is probably a good thing as it will be simpler... It should at least give ideas about how to encapsulate the data over scsi... it isn't like TCP/IP encapsulaiton is a new...

Obviously a SCSI based Ethernet card caters to a different problem than built in Ethernet or add-on boards.... and doesn't have the advantage of being able to use a DeclROM driver.. That said it is a solution that doesn't require opening your Mac or interfering with other modifications... so...

Just bear in mind that using an ESP8266 is separate from direct Ethernet or WiFi support... since they are WiFi to Serial converters.... so basically you only have access to a socket that is handled on the ESP instead of actually having control of the TCP stack.. it just means the code for...

Also more on topic.. the TinySCSI is not a Disk Emulator only... it is a SCSI peripheral emulator, SCSI cabletron Ethernet emulation is in the works among other things... and the author even put Scuzzygraph emulation on the wishlist. Currently the Ethernet drivers crash with it.. but nobody...

SCSI2SD already supports SDXC AFAIK... I should test with my 128Gb uSD (44 Bucks on amazon) card I use for my action cam... lol I have the powerbook version in my SparcBook 3GX it works great and Micheal McMaster is a nice guy.... even on the older firmwares I'm sure he would fix bugs if people...

That makes sense about the DDR QSPI....I saw DDR and immediately thought SDRAM. The proprietary Apollo core does much better than 1 IPC ... IIRC it does more like 4 instructions per cycle max and averaging around 2.5. .... It throws alot of FPGA resources at the problem...

This guy has a goal of emulating cabletron SCSI ethernet + maybe others. Plus the device can probably also act as a disk drive at the same time. I also mentioned Scuzzygraph emulation and he seemed interested in that as well.... Also basing something on something that already exists is a valid...

The Problem with the ice40... is DDR probably wouldn't even fit in a 1k part, and would use up nearly 50% of a 4k part...that's and edducated guess based on the LUT figures for other lattice parts. SDR SDRAM fits in under 150LUTS for ice40 and they give you the code for that ... I'm not sure...

such things become an issue above about 20Mhz, 50Mhz was refered to as black magic stuff back in the days of SparcStations... (thats the max speed mbus will run at it maxes out at 40Mhz on the SS20 for instance as it isn't designed well enough to be reliable above that but the Hyperstation 30...

http://experiment-s.de/en/<- this guy has 68030 emulation code working for Atari for his Suska series of boards... he seems to not be updating much lately but he does cool stuff like most people around here. Personally I think emulating the cpu on an ARM is self defeating, and probably not...

Ram.... limitations???? Anything specific because the SE/30 supports 128Mb ram and with a flashed rom you can also disable the long ram check.

So... can you use this as a direct replacement for the SE/30 tube? Or is there something I missed there.. looks like you are only using it connected to a separate mac with VGA out at the moment?

Apparently a nice snazzy icon is needed! https://github.com/clehner/Browsy/issues/1

I agree you should logically understand the code you write.... however..... he asked for a compiler not an assembler and chances are if you are used to new compilers features you take for granted may be completely broken in the old compilers or non existant. so better to have it on hand from...
