The ULA does a lot more than handle the display ;>)

Okay, you are absolutely correct given the FORTH. I use calls to the BASIC
ROM routines from assembly and machine code, so I'm using more than just
the Z80 MPU.

Of course not ;>) But a ZX81 kit is still faster than starting from
scratch.

Try desoldering the RF modulator from a ZX81 board ;>)

Hi. Does anyone have a comparison of the performance of the various DEC
turbochannel framebuffers? Even a listing of the faster ones would
help.

That is true.

Hi.
I have this nice KXJ11-CA but I have no clue how to use it. I was able
to get to the ODT prompt, but nothing else. I need pinouts, jumper
descriptions, memory map (where are the EPROMs?), ... How to use that
digital IO port? ...
My idea is to use it in a my MicroVAX 4000-200 with the VAX as "frontend
processor". So I would be able to run NetBSD/vax and perhaps 2.9BSD in
the same box.

Yes, but if the connectors on both ends are the same I would be
able to use a SCSI cable to go from the 4000 to the HSD05.

Hmmm, is there going to be one up here around Connecticut sometime?

! Sounds like I need to either find a smaller PowerSupply, or
! else I'm going to have to have it external to the system
! (which I don't want).
What about taking the power supply out of the metal case? (Re)build a power
supply to fit? Also, I have seen some pretty small ATX power supplies. about
1/2 to 2/3 the size of an AT PSU...

Way back in '77 (I think), I got a mailing from TI advertising and
offerring for sale the TI Programmer, which was a simple 4-function
calculator in that standard black-plastic format they used to use,
replete with the also-standard LEDs. However, it wasn't actually a
four-function calculator, because it included radix conversion and
several standard logical operators.
At home, when I need radix conversion, instead of the Casio Fx-115m or
the Calc accessory, I still reach for the TI Programmer...
