Knew someone would look. ;)
Has anyone
designed a quick-n-dirty Qbus IDE adapter?
see ftp://digital.dp.ua/DEC/ata/ ATA disk interface
See above.
BOOT EPROM or Flash
MRV11 with what you need in eprom or MXV11
M8189 11/23 takes eproms on the cpu.
Crystal CS8900 Ethernet
DELQA
512KW SRAM
MS11 memoriesare out there.
SuperIO (ie; WinBond)
or
NS16550A (or eqiv high-speed, deep FIFO) UART for networking/kermit
Floppy ctrlr (capable of driving Shugart 8", 5.25" 3")
Well the 16550 is basically a DZV-11, DHV11, that will get you a
bunch of lines good to 38kb
FDC for the mix if 3.5 or 5.25 is RQDX3, late rom.
5.25 is rx50(400k) and rx33(1.2m)
3.5 is rx23(1.44m) and rx24(720k)
8" is RX02/RX12. 256k/512k with 256k standard sssd 8"
media and formatting.
ISA Bridge
Why bother.
Now if you wanted that all on a 8x9" board then I'd perk up my years.
